What Are Pre-engineered Steel Building Systems?

A pre-engineered steel building system is a building enclosure system that often includes roofing and wall cladding. These...

structural systems generally consist of rigid frames that are fabricated from plate steel which has been shaped through a manufacturing process. The frames created can span large distances without intermediate supporting columns, often up to 300 feet across or more.

On top of and running perpendicular to these frames are roof secondary structural spanning members often referred to as purlins. They are spaced several feet apart across the width of a building. The roofing system attaches to the purlins. The wall systems include wall secondary structural members called girts that also span from frame to frame. Girts support a wall cladding system (frequently metal panel.)

Like their namesake, pre-engineered buildings are planned, designed, and manufactured in advance of their installation. Materials for these systems are factory produced through a mixture of highly controlled manual and automated methods and techniques. The prefabricated constituents are then shipped to the specific field site for easy and quick bolt-together assembly.

A pre-engineered steel building is advantageous because it allows for the creation of column-free enclosures of just about any size, and at a reasonable cost. Other structural framing choices, such as mill steel and light gauge metal, use more steel and are often manufactured on-site, making them markedly more expensive to build with.

There is no single preferred application for prefabricated steel buildings. While commonly known for their storage, warehouse, and agricultural uses, their renowned versatility and flexibility makes them equally useful in retail stores, shopping centers, motels, auto dealerships, office complexes, airplane hangars, sports and entertainment arenas as well as schools, libraries, churches, medical facilities, and government buildings.

The pre-engineered steel fabrication industry has evolved over the years to include structural elements that work in unison to provide a construction system that combines the best in efficiency, sustainability, safety, and pricing. Each part of a pre-engineered system is designed to precisely fit together, allowing for them to be built with greater speed and accuracy. Additionally, steel systems construction offers significant cost and performance advantages over conventional construction methods including lower life cycle costs for greater return on investment, unlimited design flexibility and sustainability attributes such as 100 percent recycled steel and thermal insulation accessories.

Our Steel Systems

Our world-class steel building systems are designed to be affordable and include premier features that are often left out of lower-budget packages offered by other steel retailers. Each structure is designed with its future (as well as its owner’s) in mind, which means high durability, increased value, and the best resistance to weather, fire, insect and water damage that money can buy.

All Allied Steel prefab steel systems come stock with the following building details:

  • 100 percent commercial-grade steel framing, cut to length, welded to shape, and drilled for quick bolt-together assembly.
  • Clips pre-welded for easy attachment of girts and purlins.
  • High-strength bolts and nuts for reinforced framing connections.
  • Framing for openings up to 30 feet across, conventional and standard.
  • Options for finishing and trimming of your choice.
  • The promise that the framing will meet or exceed all structural local building codes.
  • Cover trim for all framed openings.
  • Engineered plans and all required letters of certification.

Most of our pre-engineered systems can be planned, designed, manufactured and shipped for assembly within several weeks of receipt of order, though particular complicated bids may take slightly longer.
