Bolts are one of the main fasteners for steel structure connections. High-strength bolts, ordinary bolts and friction type bolts are commonly used. High-strength bolts usually use a tooth-shaped structure that can withstand higher tension. Ordinary bolts have a lower load-bearing capacity and are generally used in some light load applications. Washers are mainly used to prevent loosening and friction between bolts and nuts.

Expansion bolts, also known as rooting bolts, are mainly used to fix the connection between steel structures and concrete or fiberglass structures. Its main components are anchors, pipe sleeves, expansion cores and nuts. When used, the expansion core is riveted on the anchor rod first, and then inserted into the pre-drilled or grouting hole. When the nut is tightened, the expansion core in the anchor rod will generate expansion force, so that the steel member is firmly fixed on the concrete or fiberglass member.

Welded connectors are a type of fastener that connects steel components by arc welding. They can withstand high-strength forces, but the quality of welding directly affects the service life and strength of the connectors. Therefore, strict quality control of welding technology is required to ensure the quality and safety of welded joints.

Anchors are usually used to install steel structures on concrete or stone walls to ensure the stability and safety of steel structures. There are many types of anchors, common ones are pre-embedded anchors, mechanical anchors, chemical anchors, etc. When using, you need to choose the appropriate anchors according to the specific situation to ensure their bearing capacity and safety.

Overall, there are many types of steel structure fasteners, and selecting the right one according to the application and requirements is of great significance to ensure the stability and safety of steel structures.
