Structural steel projects are used for the heavier loaded buildings that require stronger live loaded areas such as mezzanine floors, stairwells, or use of industrial equipment. Another name for this type of construction framing is wide flange, as the flanges on the hot rolled beams are typically thicker for strength. The steel connection plates that reinforces each member are already drilled for use of a heavier grade hardened steel fasteners, allowing for a specified torqued connection to each member. Also you may see a zigzag type open bar joist or truss system used for the roof or floor, which can span a great distance needed for open areas. If you have a project that meets or needs any of these requirements, LTH Steel Structures will configure the complete structural framing package engineered for your particular use. To save valuable time during construction, steel members are pre-cut, pre-drilled and pre-welded where applicable, and will included any freight to your building site destination. 770-781-8279 larry@lthsteelstructures.com
