Your steel metal building or barn will need a good slab to sit on. And the slab will need to be reinforced.

There are three primary purposes for reinforcing slabs-on-grade and they are:

Shrinkage Control
Shrinkage control is the greatest design concern with slabs-on-grade. Steel reinforcing along with joint spacing offer two primary elements that can be effective in controlling shrinkage cracks. The most common mistake among designers and engineers is not providing enough of steel reinforcing for a slab-on-grade.

Temperature Control
Concrete is brittle — it is very susceptible to additional cracking and fracturing by dramatic changes in weather. The change in temperature is commonly referred to as Temperature Gradient. Steel reinforcing offers the best assistance because it essentially has the same coefficient of thermal expansion, thereby expanding and contracting at the same rate as the concrete.

Moment Capacity
Slabs-on-grade design procedures usually provide a designer with the slab thickness. The thickness of the slab is a function of loading, subgrade, modulus of rupture for concrete, and slab stiffness.
As you can there are three primary design considerations for a every foundation:
