Our 200’ x 400’ all Steel I-beam construction buildings are available in a variety of heights. These buildings can extend to any length, and are clear span which allows for use of the entire floor space as well as the space under the roof. Interior columns are not needed to support the engineered steel structure. These building kits are easy to install, and will save you money on erection costs for your commercial project. Overhead doors, windows, and store-fronts can all be added, as well as lean-to’s and mezzanines if you desire a second floor. Great Western Steel Buildings come standard with a lifetime structural warranty, as well as paint warranties and 24/7 erection support. If you are on a tight timeline, we can deliver quickly or if you need to spend time finalizing your design we are flexible and can make changes to your project after you place your order.
