Structural Bolts are a specialized heavy type of hex bolt intended for use in large structures, such as buildings and bridges. This bolt is designed to withstand the loads of steel-to-steel structural connections. They contain a flat, washer-faced bearing surface and a chamfered thread point. Plain finish, or bare metal, may or may not have a coating of light oil to resist corrosion.
From raw materials to end product delivery, it has a strict control program. Accurate completion is done about:
Standard parts: wiring- roughing – annealing- pickling – drawing – heading(cold forging or hot forging) – threading(rolling) – heat treatment -surface treatment –cleaning –inspecting-packaging
Customization parts: heading, stamping or casting-wire cut edm machine -CNC (machining center) -grinder threading(rolling) – heat treatment -surface treatment –cleaning –inspecting-packaging.
