Structural bolts are critical to various constructions including bridges, factories and mechanical equipment for structural connections. Because these construction projects require structural bolts to have high hardness and tensile strength, raw materials must be strictly selected and processed by specialty equipment. And the bolts and nuts are heat treated to increase their strength and hardness, thus satisfying a broad range of applications.
Since its establishment in 1985, HUIXIN MINDA has been specialized in engineering, manufacturing and supplying of high strength structural bolts, especially in production of high strength bolts for steel frame constructions. With our cold heading machines and hot forging presses, we are capable of manufacturing high strength structural bolts in various specifications to endure high loads according to your drawings and requirements.
Our structural bolts are made of selection of materials is used to produce, such as 20MnTiB, 35CrMo, 40Cr, etc. and are available in GB, DIN, ISO, ANSI/ASTM, BS, JIS standards.
