Coupler

Couplers: the core connecting components of construction engineering Couplers are the key accessories used to connect various components in the field of construction and engineering, and the core function is to fix steel pipes, profiles and other structural parts into a stable frame, which is commonly used in scaffolding, support frames, storage shelves and other scenarios, and is mainly divided into two categories: cast iron Couplers and forged Couplers according to the manufacturing process, adapting to different engineering needs. Cast iron Couplers are made of gray cast iron/ductile iron as raw materials, cast and made, with low cost, simple structure, tensile bearing capacity of about 8-12kN, suitable for small and medium-sized buildings, interior decoration and other light load scenarios; Forged Couplers are forged and processed with carbon steel, which has higher strength (tensile bearing capacity of more than 15kN) and strong impact resistance, and is mostly used in heavy-duty scenarios such as high-rise buildings and bridge construction. No matter what kind of Coupler it is, it must comply with the standard of "Steel Pipe Scaffolding Couplers" (GB 15831-2016), ensure that the components fit tightly during installation, regularly check for cracks, bolt slips and other problems during use, and do a good job of moisture and rust prevention when storing. As the "connecting link" of the temporary structure, the selection and maintenance of Couplers directly affect the safety of the project and are indispensable basic accessories in engineering construction.
