Types of Foundation Bolts and When to Use Them
Not all foundation bolts are created equal, and using the wrong type can cause serious alignment and safety issues. Common types include J-type foundation bolts , ideal for light to medium loads like small steel columns and wall-mounted structures, and L-type bolts, which provide better pull-out resistance for medium-load applications like warehouses and factories. For machinery requiring future adjustments, sleeve-type foundation bolts are the go-to, allowing the bolt to be removed or replaced without disturbing the concrete base. Straight anchor bolts with nuts and washers are preferred for high-precision projects like bridges, metro rail systems, and large industrial equipment installations. The key to choosing the right foundation bolt lies in matching its design to the structure’s specific requirements. For example, foundation bolts for pre-engineered buildings (PEBs) must handle both wind loads and weight transfer, while anchor bolts for corrosive environments require hot-...
