Choosing the Best Anchors for Your New Metal Building

By Jay Lara   |   Posted In: Installations

Customers often question which anchor is ideal for their new custom metal building and its foundation. Selecting the right anchor will help your custom carport, garage, or other structure stay secured to the ground when faced with the elements. 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 type of anchor you need depends on the surface that your custom metal building will be installed on. Metal building manufacturers recommend that, regardless of the weather, you select an asphalt or concrete base to prevent erosion around the foundation. Here are the different types of anchors used for metal carports, garages, and other buildings:

Asphalt Anchors

Since asphalt is made with tiny particles such as small stones, gravel, or sand, the asphalt is likely to compromise under pressure. Therefore, the anchors are designed with barbs or screw-like threads on their shafts. Since they are engineered to work with asphalt, it is not recommended using this anchor with a concrete or soil installation foundation.

Concrete Anchors

If installing on a concrete base, concrete expansion anchors are highly recommended as they are specially made for this type of foundation. Concrete expansion anchors are installed through the base rails into 3″-4” holes that are drilled into the concrete. When these anchors are installed they will then expand, thus creating a firm foundation with the concrete base.

Mobile Home (Auger) Anchors

Often referred to as auger anchors, mobile home anchors are great for securing your steel building to dirt or soil. Even though a poured foundation isn’t required, the ground must still be level for a firm hold. If you plan on certifying your metal carport or other metal building, these anchors are recommended as they are the only ones that qualify for certified ground installation.

Rebar Anchors

These ½” x 32” anchors are often used for installation of metal garages and buildings on gravel or soil foundations. During installation, the anchor will be fixed into the base of the rail and then secured into the ground. They work best in areas with sturdy soil and low winds, providing strength and stability to your custom structure.
