Are you trying to determine which of the types of commercial concrete foundations will be ideal for your steel building? It’s an important consideration because the foundation is literally the support of the building. The right foundation will resist the loads from the building as well as loads from the climate, which means your steel building will be more durable and stand stronger for longer.
When designing a steel building foundation, building engineers will provide the requirements and guidelines necessary for the loading and anchor bolts. This information enables the foundation engineers to make sure the foundation is sufficient to support the building.

The excavation process of the foundation area will depend on the type of foundation the builder chooses to use. While a shallow excavation is possible by hand, deep excavation for foundations measuring over three inches typically requires the use of heavy, professional construction equipment.
Nearly all pre-fab steel buildings will require one of two commercial foundation designs: footing design or slab on grade design. Keep reading to figure out which one is right for your steel building:
Footing Design Foundations
Footing design, also known as T-shaped footing, is the foundation style that involves the installation of spread footings under each of the columns of the steel building. The footings are installed just below the frost line, and the pilasters stretch to the bottom of each column. A continuous wall or beam connects the pilasters and footing around the perimeter of the building. Then, concrete fills the space between the beams.
Slab on Grade Design Foundations
Also known as thickened edge design, a slab on grade design foundation is typically ideal for smaller steel buildings. The design is also economical for buildings that are in areas with lower frost levels.
In addition to these two foundation designs, you will also need to choose the right foundation type. The wrong foundation type can mean a weak base for your building, so it is important to have professional assistance as you choose the right foundation.
The three most common types we see for steel building foundations are:
- Floating slabs: a foundation with one continuous grade that features reinforcement at the bottom or spreads under the steel columns.
- Footing and grade beams: a foundation with rectangular and square footings that get their support from grade beams.
- Drilled piers: a foundation that has vertical piers instead of footings; these piers are a result of deep holes that the foundation professionals drilled into the ground.
