What size should the concrete slab be for my steel carport, building or garage?

The concrete slab should be a minimum of 6” larger each side and end than the overall unit size. The length of the base rail is always 6″ shorter on each end or overall 1′ shorter than the roof line of the structure. For example: If you order a 12′ x 21′ carport, the foot print is 12′ x 20′ So your concrete would need to be poured at 12′ 6″ x 20′ 6″

How will my steel carport, building or garage be anchored when it is installed?

All “Non-Certified” carports have rebar pin anchors for ground installations. If you choose, you can upgrade to mobile home anchors for ground or asphalt anchors for an additional charge. If the structure is going on slab, footing or stem wall we will use concrete wedge anchor bolts to secure the structure. If you choose to have a Certified carport, building or garage on the ground, you will need to purchase mobile home anchors. Our engineers will determine how many anchors you will need to meet your areas wind and/or snow loads.
