Customers often wonder about the best type of anchor for their new custom metal building. Selecting the right anchor will help your prefab carport, garage, or other structure stay securely affixed to the ground when faced with periods of high wind and strong storms. Failing to use the proper anchors can compromise the strength and stability of even the best steel buildings. At Carport Central, we are committed to helping you choose the appropriate anchors for your new structure.
The anchors you select will depend on the type of surface that your prefab metal building will be installed on. Metal building manufacturers recommend that, regardless of the weather in your area, you go with an asphalt or concrete base to prevent erosion around the foundation of your custom steel building. That said, here are the different types of anchors used for metal carports, garages, sheds, barns, workshops, and other buildings. In each case, anchors are installed through the base rails of the buildings at various points.
As the name indicates, these anchors are designed especially with barbs or screw-like threads on their shafts to keep them securely planted without compromising asphalt, which is made of sand, gravel, and tiny stones.
These are perfect anchors to secure your new metal building to a concrete base. Concrete expansion anchors are installed through the base rails into 3-4” holes in the concrete base. When installed, the anchors expand. These only work with concrete, because the expansion would cause fracturing if used in asphalt.
Often referred to as auger anchors, mobile home anchors are great for keeping your steel building secured to dirt or soil. These work well for dirt foundations because once driven into the dirt, the augers firmly catch on the soil. If you plan on certifying your metal carport or other building, these anchors are the only ones that qualify for certified ground installation. They are recommended for areas with high winds or loose soil.
These ½” x 32” steel anchors are often used for installation of metal garages and buildings on gravel or soil foundations. Rebar anchors work best in areas with sturdy (not sandy) soil and light winds. If you are in a high wind area, or one with loose soil, auger anchors would be a better option to secure your structure.
At Carport Central, we are committed to helping you choose the best anchors for your new metal building, so feel free to contact us if you need help deciding which anchor would best suit your needs based on your foundation and the weather in your local area.
