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.
