Most our metal buiding structure connection is Bolting，as a result, our steel structure buildings are not only easy to install and disassemble, but also reduce the number of containers used when shipping.
Bolt connection divided into ordinary bolts and high-strength bolts.
Ordinary bolts divided into C bolts and A, B bolts. Class A, B bolts are suitable for the installation of essential structures where large shear forces need to transmit at the connection part. And Class C bolts are ideal for temporary fixing in the erection of steel structures.
Ordinary bolts are for temporary connection and the connection of removable static load structures. Among them, Class A and B bolts rarely used at present, and high-strength bolts replace them. Therefore, the standard bolts generally refer to C bolts.
High-strength bolts divided into friction-type bolts and pressure-bearing bolts.
High-strength friction bolts currently widely used in industrial, civil construction steel structure connections. They are the most suitable connection method for bearing dynamic loads among various links. They often used in essential parts of on-site splicing and installation connections. Where structures are not ideal for welding can replace with high-strength bolts. High-strength friction type bolts are the most common bolt form in the steel structure design.
