Our company is structural bolts factory, structural bolts manufacturers, structural bolts suppliers. We structural bolts specifications are complete, the quality is stable, the delivery is fast, the service is thoughtful, welcome to order. structural bolts are used for the connection and fixing of steel structural parts of various buildings and bridges. The use of structural bolts to connect large steel structure parts has become an important trend in fastening field. The main structural bolts are ASTM A490 bolts, A325 bolts, ASTM A193, A307 bolt, ASTM F3125, F3125M, etc. structural bolts are made of high-strength steel and require a large pretension. Structural bolts has good seismic properties and mechanical, and resistance to fatigue. Its connection stiffness is high, construction is simple, more used for railroad, bridge, high pressure and ultra high pressure equipment connection.

structural bolts are used to connect structural members.
