Steel Buildings vs. Conventional ConstructionA great advantage of pre-engineered buildings is that they can be relocated if required. Since your building is shipped to you with a complete set of instructions, detailed engineering drawings and a shipping list, you can erect you steel building without consulting a construction company. This also means that should you someday decide to relocate, you can take down your building and erect it elsewhere.
Adding partition walls in a steel building allows one building to be a meeting room, or office and storage facility and another to be a restaurant. Building with steel gives you the ultimate in design flexibility. You can either own one outright or purchase a steel building to rent to others. Your one time cost is regained sooner rather than later when you rent it as mini storage or public meeting space. Steel buildings can be designed with a almost unlimited amount of options.
If you have a need for a new building, don't make a decision until you have explored your options with a qualified steel building manufacturer. The Steel Building Network has reviewed a wide range of manufacturers, suppliers and building industry professionals, and we know that no matter what your intended use, there is steel building system to suit your needs. Getting I contact with the right company to get your questions answered is the first step in having your building needs met.
FoundationsDo I need a foundation for my metal building? - Some people choose to pour a full slab foundation, however if you're planning on leaving the floor in a dirt or gravel condition, concrete piers will do the job just fine. Please contact a customer service representative if you don't plan to pour a full slab foundation.
Can you provide an engineer stamped foundation layout? - Yes, but in some cases your soil conditions play a major role in the type of foundation you can use. Contact our special sales department for more information. If using a local engineer, we will provide anchor bolt plans to aid your engineer in designing the foundation.
Do you supply the hardware to attach the frame to foundation? - No, the anchor bolts are usually supplied by a concrete contractor and placed when the foundation is poured.
Structural DesignWe design and manufacture pre-engineered steel buildings, and offer you a number of advantages over conventional construction techniques. Steel buildings are inexpensive and incredibly tough. Our bolt-together design is assembled quickly without any specialized skills. Each rigid frame is comprised of two or more columns supporting a rafter across the width of the building. In most steel buildings, endwall bearing frames support one-half the load of a rigid "main" frame. In most situations, we utilize the more economical "bearing" end frames. Adding an expandable endwall or rigid frame is only a click away. Unlike any of our competitors, we allow you to choose the endwall condition of your building. Depending on design considerations, our endwall rafters and columns may be either hot rolled or cold-formed.
The space between the rigid frames of a steel building is referred to as a "bay."- an 80' long building has been divided into four 20' bays by spacing the frames 20' apart (4 x 20' = 80'). This configuration is described as "four bays at 20." A 100' building could be configured with four bays at 25 (4x 25' = 100')
Endwall bay spacing is usually determined by the building width. You can add one or more framed openings to most buildings. Endwall bay spacing can usually changed to accommodate your needs without changing the price.
Heat TransferEffectively controlling temperature in a steel building requires insulation to be present along exterior walls and roof. When a temperature differential is present in an enclosed steel building, heat will work from warmer areas to colder areas until the temperature in the building has stabilized. At the point of thermal stabilization, the cooler (and heavier) air will be present at lower elevations and warmer air will be present at the roofline. The function of insulation is to help stabilize air temperature at more desirable levels. When it is hot outside, preventing heat from transferring into the building is the goal, and of course in the winter we want heat to remain inside.
Heat transfer occurs in three ways:
Conduction : Occurs in a solid or liquid when heat from one object is transferred by touch to another object. An example of this occurs when a pot on a stove will heat up by conductive heat transfer from an electric coil.
Convection : Occurs with the physical movement of air. There are two types of convectional heat movement. The first is natural, where hot air rises displacing the cold air and moving it down. The second type is forced or mechanical convection. This occurs when an object, like a fan, physically moves or "forces" the air to move.
Radiation : Occurs when an object is warmer or hotter than the air around it. For example, the sun, which is hotter than everything around it, radiates heat waves that travel through the air and is either absorbed by or reflected by the surface it comes in contact with.
Installation and Selection of InsulationWe provide the highest quality products available. However, proper installation and selection is imperative for maximum effectiveness. Please refer to installation instructions to ensure correct procedures are used. Facings that have been torn or punctured are no longer capable of blocking water vapor and may eventually do more harm than good. Be sure to quickly patch any holes in the vapor barrier.
When selecting a facing, special consideration should be given to its reflective quality. A facing with high reflectivity reduces the need for high light levels in work areas. This results in reduced energy costs and increased productivity.
Although the fiberglass insulation itself is not affected by cold weather, the facing is. Colder temperatures can cause cold crack, a situation where the facing becomes brittle and if handled can crack. Bay Insulation recommends that vinyl faced fiberglass products never be installed in temperatures below 40 degrees.
