What is the material of the seat belt

It is expressly stipulated in the seat belt standard that welded semi-circular rings, triangle rings, 8-shaped rings, pin-shaped rings and circular rings are not allowed. However, in order to reduce production costs, some enterprises still use welding parts to assemble seat belts, and some users have not paid enough attention to this problem, which has a great hidden safety hazard. The welding process itself is an ancient production process. If the welding quality is good, the strength of the welding joint will not be lower than that of other parts of the fittings; if the welding quality is not good, the metal parts will be disconnected from the welding joint first when they are stressed. Most of the enterprises that produce welded parts are informal manufacturers with low technical level, poor processing ability, and quality cannot be guaranteed. It is very dangerous to use such accessories to assemble seat belts. In the event of a fall accident, casualties are inevitable. Therefore, both producers, sellers and users should pay enough attention to this problem and control the quality individually.
