What Is a Steel Building Kit?

Worldwide Steel Buildings manufactures metal and steel building kits right here in the USA, with the DIY builder in mind. That’s right, you save money because you’re buying direct from the factory and building it yourself. We provide step-by-step instructions, along with pre-punched and pre-welded pieces so that all you have to do is bolt or screw pieces together. It really is that easy to increase your property value and get the metal building you’ve always wanted.

Steel building kits make construction cheaper, faster, easier, and more efficient. Instead of buying all of your materials separately and hiring a contractor, everything you need is in one convenient package. We specialize in helping DIYers get the steel building building of their dreams. Our customers are the best example of the versatility of these pre-engineered steel building kits. They’ve built everything from custom homes to horse riding arenas, to barns and farm buildings. See some of our finished steel buildings in the gallery below or view more examples by building kit type.


What Is Included in a Worldwide Steel Building Kit?

Remember when you were a kid and the words “batteries not included” could ruin your day? We do too, which is why we’ve made sure to include as much as possible in these steel building kits. With help from your own basic toolbox, extension ladder, tin snips, screw gun, and metal cutting blade, you’ll have almost everything you need to assemble your kit. This means no renting expensive specialized tools, no hiring contractors, no running out to get more unexpected materials, and no reasons to slow down while you build the steel structure of your dreams. The only other thing you’ll need when your steel building kit arrives is a way to unload the materials from the delivery truck and to hoist supports during assembly. Our metal building kits arrive at your property ready to be assembled.

What Do I Do When My Kit Arrives?


  • There should be a definite loading and unloading plan. Least-handled material is usually safest-handled.
  • Have equipment on site to unload off a flat bed trailer, safety should always come first.
  • Your building will come in bundles for easy manageable weights.
  • Everyone should keep hands and feet clear and from under material.

tools needed for steel building kitHANDLING
On jobsites, reasonable care should be taken when handling painted surfaces during installation in order to protect the finish. Although the paint coating is tough and provides impact resistance, dragging the sheets across the surface of one another will mar the finish.


These DIY steel building kits come equipped with easy-to-read building instructions and, besides your toolbox basics, all you’ll need are these five tools for assembly:

  • A way to transport the materials to the building site and to hoist it into place. If you don’t have a tractor or a skytrack, look into renting one for the weekend.
  • Extension Ladder
  • Tin Snips
  • Screw Gun
  • Metal Cutting Blade

To preserve and protect the attractive appearance of your roofing and siding from damage caused by moisture, corrosive chemicals or improper handling it is necessary that you take a few simple precautions. When material is received bundled, sheets should be inspected for shipping damage. If present, the carrier should be advised and a notation made on the B.O.L. . . . (Bill Of Lading).

Prolonged storage of sheets in bundles is not recommended. If conditions do not permit immediate assembly, extra care must be taken to protect the material from damage caused by moisture.

Store bundled sheets IN A DRY PLACE ONLY. Strapping bands should be broken and sheets should be blocked off the floor with one end slightly elevated. Stacked sheets should then be completely protected from the elements while maintaining good air flow to prevent condensation. A properly draped canvas tarp is an example of a good protective cover. Do not use plastic, as it causes sweating or condensation to occur.
