Work with Our Team to Design Your Gym

Working with General Steel is a collaborative process that ensures that your final product reflects your specific needs. The process starts with a two-way conversation between you and our experienced team. We want to know exactly how you’ll be using your gymnasium, how it fits within your property, and your ideas for interior and exterior design, among other factors. We then research the location of the building to ensure that your gymnasium or gymnatorium is equipped to withstand the wind and snow loads of your area as well as any insulation requirements.

Once we get an idea of what building kit best suits your project, we work with you to add customization options, including a wide variety of doors, windows, and exterior color schemes. The ease of steel construction allows us to modify layouts and add further customizations without breaking your budget. From design to construction, we provide the materials and expertise to transform a building kit into a gymnasium.

Easy Construction and Reliable Durability

While steel is best known for its strength, there are a few other factors that make steel a superior building material. One advantage of steel construction is the use of clear span framing. This construction feature provides 300 feet of column-free floor space, which is especially important when installing sports fields or courts.

Another advantage of steel construction when compared to traditional building materials is efficiency. A gymnasium often requires highly specialized features, which not only come with high costs, but also extend your project timeline if you’re using wood or brick. Steel building kits are erected using simple, bolt-together construction, which allows you to save on labor costs and materials.
