With a wide range, good quality, reasonable prices and stylish designs, our products are extensively used in Mold, Electricity, Construction, Solar energy, Automotive, Machinery & Equipment and other industries.
Our company has purchased steel from several large steel groups, whose steel have good mechanical properties and stability of chemical component, it keeps the Mild Steel Hex Bolts to be of high strength.
We have many years of production experience in the production of fasteners. We not only have new imported production equipment and spacious storage space,but also have a group of experienced workers and professional engineering R & D team. Therefore, our company has enough strength to meet the needs of customers.
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.
Perfect Quality:
We have strict quality control from producing to delivery. Our company had strong technology support. We have cultivated a group of managers who are familiar with product quality, good at modern concept of management.
