Metal Buildings, Leading the Green Construction Movement

Tuesday, March 22nd, 2011

The protection and preservation of the earth’s remaining natural resources is now a global concern. The construction industry is well aware of this, that’s why it started the green construction movement. The American public’s response is positive.

Nowadays, the growing awareness of “going green”, coupled with the rising costs of energy, has increased the demand for structures that use environmentally friendly and energy efficient materials.

For using sustainable design practices and materials, metal buildings are leading the way in the green construction movement. Actually, the metal building industry has been doing this even before the green movement was conceptualized.

The core element in metal buildings is steel, the most recyclable building material today. Steel is 100 percent recyclable and the rate at which it can be recycled going as high as 60 percent.

Metal buildings are highly customizable. These metal structures are custom-designed by engineers based on the specifications of the customer, with building codes factored in. This technique allows for efficient usage of materials. The structural members are cut accordingly based on the design loads, no more, no less, resulting in minimal waste materials, and if there are any, would be recycled to create new steel.

Expansion of metal buildings is a hassle-free project. Existing structural members and wall systems can be easily re-used – a process which is not always possible with traditional methods of construction.

Another sustainable practice in the design of metal buildings that makes these structures energy efficient, is the use of the right amount of insulation. Installing insulation in the roof and walls of metal buildings is an easy task that results in structures that are highly thermal performing – low energy consumption.

The use of metal roofs or “cool roofs” is another plus for metal buildings. In places with warm climates and in cities where urban heat island effects are a great concern, metal roofs can be the best option. Today, developments in coating and pigment technology have resulted in cool coatings for metal roofs, increasing their energy efficiency even when the roof is dark-colored.

Major developers around the country are spending billions of dollars in the construction of office buildings, apartments, and homes that are certified to be environmentally friendly. It would not be a surprise that these structures are not made of traditional materials, but instead, are mostly metal buildings.

American Steel Buildings Offer More Benefits Than Other Construction Methods

Thursday, March 17th, 2011

Compared with traditional construction methods, prefabricated steel buildings are more attractive to American consumers because they are affordable, aside from their many other benefits. American steel buildings are strong, durable, and are resistant to fire, rust, termites, vermin, rot, mold, and mildew. In fact, they are virtually maintenance free.

All these benefits are mainly due to the main material used in American steel buildings, high-grade steel. Building with steel is environment-friendly because this material is highly recyclable. The following list enumerates the many other benefits of steel construction provided by American steel buildings.

· Steel is resistant to corrosion and decay more than any other construction material.
· American steel buildings are resistant to fires, floods, hurricanes, high winds, and heavy snow.
· The structural framing of American steel buildings will not warp or settle like its wooden counterpart. Steel framed American steel buildings are structurally sound, remain stay straight and true throughout their entire lifetime.
· American steel buildings are more economical in the long run, when compared with other conventional construction methods.
· Though steel framing is lightweight, it is extremely strong. In fact, the strength-to-weight ratio of steel is the highest among all construction materials.
· American steel buildings are designed to meet customers’ specifications and applicable building codes.
· Another highly desirable physical property of steel is its elasticity. Steel comes back to its original shape when the deforming forces are removed, making them resistant to seismic events.
· Steel fabrication strictly follows national standards, so wherever it is produced, it has the same quality.
· Construction of American steel buildings provides no surprises. Since they are prefabricated, assembly is fast, efficient, with firm timetables. In fact, compared to any other construction method, it takes 1/3 less time to erect a steel framed building.

Metal Building Systems

Tuesday, February 22nd, 2011

Due to modern technological advancements and improvements over the past years, metal building systems have become one of the top choices for various building configurations. In other words, metal is now considered to be a more flexible construction component than ever before.

Metal, most especially steel, is preferred by most architects and construction engineers because it is highly customizable and portable. In fact, steel building systems can be built to span large distances due to steel’s high strength-to-weight ratio. As a result, metal buildings systems are now regarded as a viable submarket within the construction industry.

Metal building systems are easy to erect and take lesser time to build. These structures are constructed “on-site” by assembling together sections of the building components, which are manufactured in factories. Metal building systems offer sustainable solutions for most construction needs because they do not contribute to non-biodegradable wastes. Why? Because they are energy efficient and highly recyclable, making them cost-effective and practical choices, as well.

Metal building systems offer other benefits including easy expandability and they also require minimal maintenance. These structures are not prone to mold, warp, rot, or rust. Applications of metal building systems include schools, airplane hangars, garages, agricultural structures, storage sheds, barns, institutional buildings, factories, and warehouses.

If you are seriously thinking of venturing into a metal building project, here are some guidelines to help you with your decisions and lessen your headaches. Ask yourself the following questions:

· What is the purpose of your metal building?
· Would you be able to acquire a building permit for your project?
· Would your metal building need insulation?
· Do you foresee any future expansion plans for your metal building?
· Will you build it yourself or do you need a builder?
· How many floors will your metal building have?
· What are your preferences for the building’s interior and exterior finishes?
· Do you need a clear-span frame? What do you think is the ideal width of your metal building?

Answering these questions will help you acquire the metal building that meets your particular needs and specifications and at the same time ensure that you will get the most out of your metal building.

Steel Buildings Offer Peace of Mind for Owners

Tuesday, February 8th, 2011

Steel buildings are durable, sturdy, low maintenance, and energy efficient structures that are very easy to build. These make them popular choices of homeowners and businessmen, alike. But the best selling point of steel buildings is the long warranties offered by suppliers of these metal structures.

Reputable suppliers of steel buildings offer warranties such as:
· 50 year structural warranty
· 40 year paint warranty on finishes used on panels, gutters, and downspouts
· lifetime warranty against rust on all stainless steel fasteners used on walls and roof

This shows that these suppliers are very confident on the quality and structural integrity of these metal structures. As a consumer, a warranty is your guarantee that any defects of the product you are buying, will be corrected at the manufacturer’s expense during the period that the warranty is in effect.

Oftentimes the warranties play an important role in a consumer’s decision in purchasing a steel building – sometimes more than the price. Steel buildings that come with longer warranties provide “peace of mind” to building owners. A long warranty enhances the worth of steel buildings and adds value to the consumers’ investments knowing that there is protection from potential costs of future repairs.

Why do steel buildings come with longer warranties that are not offered by other conventional methods of construction? Suppliers of steel buildings that are of good standing use laser-precision engineering in the manufacture of these metal structures.

Reputable suppliers even go to the extent of utilizing 3D modeling technology to digitally “build” steel buildings on computer screens that show detailers precisely where bolt connections are required. All these cutting-edge technologies allow the production of faultless steel buildings that have superior structural integrity and longer warranties.

Earthquake-Resistant Steel Buildings

Friday, January 14th, 2011

Steel buildings are well known for their resistance to extreme weather conditions such as high winds, hurricanes, and tornados. In fact, the evidence is on record of how well these metal buildings stand up to major weather disturbances. What is left standing and still intact after major disasters such as hurricanes, are the steel buildings built up to code and made of high-grade steel.

But how do steel buildings perform during earthquakes? The favorable performance of steel buildings in numerous violent earthquakes in the country (San Francisco, Santa Barbara, and Long Beach), has contributed to their proliferation. Engineers became convinced that steel is the material of choice as far as building earthquake-resistant structures are concerned.

There are two theories on the impact of earthquakes on steel buildings. One line of reasoning states, that an earthquake is a result from the movement of the plates, below the earth’s surface, against each other. This creates seismic waves that travel to the surface and move out from the epicenter of the earthquake.

The other theory is largely based on inertia or the tendency of a body at rest to remain at rest unless acted upon by a force. During an earthquake, the bottom of steel buildings moves with the earth as the surface begins to move away from the structures. But inertia keeps the buildings in the same spot for a while. It has been observed that the amount of seismic force that strikes is relatively greater for steel buildings that have more weight.

On the other hand, experts agree that the amount of seismic activity is likewise determined by other factors including the type of ground that the steel buildings stand upon. There are ground characteristics that are more susceptible to seismic activity. In addition, the rigidity of buildings is another factor. The good news is, steel buildings are designed with lateral load resisting features that make them resistant to earthquakes.

Prefabricated Steel Buildings, Worthwhile Replacements for Pole Barns (continuation)

Wednesday, January 12th, 2011

The disadvantages of pole barns discussed so far are:
· Not resistant to heaving caused by flooding and frost.
· Wood used has a high probability of shrinking and warping with time
· Pressure treated wood unsafe for livestock
· Costly to maintain
· Low resistance to fire

In addition to this list, another concern for pole barns is the fact that they do not come with the proper plans and drawings needed to secure the necessary building permits and learning how the parts are going to be assembled. Construction of pole barns require painstaking hours needed for sorting, cutting, and fitting of the building components which come unnumbered and unsorted.

On the other hand, aside from plans and drawings, steel buildings come with erection manuals that are easy to read and follow. Aside from these, all the components are sorted and numbered for easy identification. As a result, construction of steel buildings is as easy as solving a jigsaw puzzle – all the components fit exactly and perfectly, eliminating the need for onsite cutting, drilling, and welding.

Furthermore, pole barns have to be re-sheeted and repainted once every eight years, causing another dent in the farmers’ pockets. An additional common problem for pole barns is rusting caused by the steel members coming in contact with the wood. These concerns are unlikely to happen with steel buildings. These metal structures are coated with materials that make them highly resistant to rust and corrosion.

Steel buildings do not need re-sheeting and re-painting. Pole barns have an average 14-year lifespan while steel buildings are certain to provide many decades of efficient use.

Prefabricated Steel Buildings, Worthwhile Replacements for Pole Barns (continuation)

Tuesday, January 11th, 2011

Steel buildings have overtaken the popularity of pole barns on the American agricultural scene because of the many advantages offered by these metal structures. Yesterday’s post talked about the unfavorable performance of wood, the main material used in pole barns. Other major considerations that made farmers shift their attention to steel buildings are discussed below.

Exposure to the elements and wear and tear cause pole barn foundation members to shift. These components need regular straightening, which is done about every six years, requiring farmers to shell out thousands of dollars for their maintenance. On the other hand, steel buildings require minimum maintenance because steel is very easy to clean and will not warp, crack, split, or rot. Besides, the steel building finishes used today are also impervious to dulling, marring, or rust.

Another very important point to consider is the safety of livestock housed in pole barns. Since pole barns are made of pressure treated wood poles using copper sulfate, they are unsanitary and can be poisonous to livestock, unlike steel buildings, which are made of steel that is very safe, non-poisonous, and does not support rotting and disease. Compared to wood, steel will not splinter or crack and is kick and bite proof.

A major disadvantage of pole barns is that they are combustible, making their insurance premiums higher by 25% when compared to those of similar sized steel buildings. In contrast, steel buildings are highly resistant to fire because they are made of non-combustible materials. Since pole barns have low resistance to fire, they are deemed unsafe for occupancy. For this reason, some communities and localities in the country do not permit their installation.

Prefabricated Steel Buildings, Worthwhile Replacements for Pole Barns

Monday, January 10th, 2011

Pole barns have previously dominated the American agricultural scene. Today, however, farmers have shifted their attention to prefabricated steel buildings because of the many benefits they offer that are unmatched by pole barns.

The popularity of pole barns was mainly due to their low cost and availability. During their heyday, pole barns were the cheapest way to build an agricultural building, aside from the fact that they were the only material available.

Aside from their durability, steel buildings offer economical solutions, which can accommodate any farmer’s construction needs, like barns and other storage buildings. The onset of prefabricated steel buildings made farmers realize that they have a better choice and that their days of putting up with the many disadvantages of pole barns, have ended.

Firstly, since pole barns are typically made with pressure treated wood, they are not resistant to molding, shrinking, warping, and rotting. In addition, the poles of a pole barn are directly planted on the ground, making the whole structure highly susceptible to heaving during floods and heavy snow. For these reasons, pole barns are not recommended for use as permanent structures.

On the other hand, the high quality steel used in prefabricated steel buildings is the strongest construction material. Steel is highly resistant to warping, molding, shrinking and rotting. During construction, the steel framing of steel buildings are bolted to a concrete foundation, making these structures sturdier and more resistant to flooding and frost than pole barns.

Steel buildings will remain straight and true despite the onslaught of extreme weather conditions like hurricanes, heavy snow, high winds, tornados, and even earthquakes.
These metal structures are certified to meet local climactic conditions and building codes.

High LEED Ratings for Steel Buildings

Thursday, December 30th, 2010

The green building movement has changed the construction industry by making it more conscious of the energy conservation and environmental impacts of construction. Thus everyone involved in this sector, including building owners, are starting to realize the benefits of sustainable construction, not only in preserving the earth’s environment but also improving the built environment.

The LEED Green Building Rating System is the prime mover of this movement. Used as a design guide and third-party certification tool, the LEED rating system has given high ratings to prefabricated steel buildings in the following categories: Sustainable Sites, Energy and Atmosphere, Materials and Resources (Recycled Content), and Use of Regional Materials.

The rating system used by LEED is point-based, which means that the number of points a project earns determines the level of certification a building project receives. With the high ratings given by LEED, owners of steel buildings can qualify for a growing array of state and local government incentives, among other benefits.

Sustainable Sites (SS Credit)

The use of reflective and emissive cool metal roofing can contribute one point toward LEED certification. Cool metal roofing for steel buildings improves energy efficiency by providing high levels of solar reflectance and high thermal emittance. Cool metal roofing keeps the indoor temperatures of steel buildings, within comfortable levels.

Energy and Atmosphere (EA Credit)

With the use of cool metal roofing and wall systems designed to provide R-values up to R-40, steel buildings have demonstrated energy performance levels beyond the prerequisite standard set by the local energy code. Cool roofs and walls help save energy and electricity costs by reducing the use of cooling and heating equipments. As a result, up to nineteen additional points may be awarded.

Materials and Resources – Recycled Content (MR Credit)

Steel buildings can earn two points under this category for the use of materials that contains at least 5% recycled content. The steel used in prefabricated steel buildings contains at least 70% recycled content, which is 100% recyclable and reusable in the future.

Use of Regional Materials

LEED gives up to two additional points for steel buildings that use regionally or locally available building materials. This encourages projects to support the regional economy and at the same time lessens the environmental impacts resulting from transporting the materials to the job site.

The Stability of Pre-engineered Steel Buildings

Friday, November 5th, 2010

Yesterday’s post talked about the rigid frame system used in pre engineered steel buildings. This post talks about how the frame system gives steel buildings the stability and reliability they are most famous for.

A typical one-story pre-engineered all-steel structure is comprised of several main frames, the number of which depends on the building’s length. The steel main frame truss is the vertical I-beam that is bolted to the concrete foundation and functions as the central support of the rigid frame.

Focusing our attention to the steel building’s width, a clear-span frame is the open space between the steel framework supports. The main frame is composed of vertical and horizontal I-beams. The vertical element of the “I” beam resists shear forces while the horizontal element resists most of the bending moment experienced by the beam.

With regards to the roof, the purlin bracing system used in roofs of steel buildings include braces, which have pairs of tabs extending from one end. These steel roof components work in harmony precisely to provide interiors that are safe against the elements. At the same time, the roof parts direct all structural loads of steel buildings to the purlins.

All buildings are subjected to constant stress from forces like compression, tension, shear, torsion, and lift. Sideways balance is essential to the reliability of steel buildings. The rigid frames of the majority of these metal structures support sideways balance because they hold all the parts together.

In addition, incorporating different types of bracing into the steel building’s design can also add more lateral stability to the structure. These bracings are very effective at combating the various building loads. In addition, they are integral to the complete rigidity of steel buildings.
