The Difference Between Threaded Rebar Coupler and Cold Extrusion Rebar Coupler


In the current booming stage of China's construction industry, there are various types of building structures, which pose higher demands on steel connections. Among the mechanical methods of steel connection, threaded rebar coupler connection and cold extrusion rebar coupler connection are two common methods. So, what are the differences between them?

In terms of the connection method, threaded rebar coupler connection involves cutting off the longitudinal and transverse ribs at the end of the rebar, then rolling them into straight threads, and finally using a coupler to connect the rebars together. This connection method is simple and fast to operate, with high connection strength and fast construction speed. On the other hand, cold extrusion rebar coupler connection involves inserting the end of the rebar into a special steel sleeve, compressing the sleeve with an extrusion machine to induce plastic deformation, thus achieving rebar connection through the mechanical interlocking force between the sleeve and the rebar.

Regardless of the chosen connection method, emphasis should be placed on quality when making a purchase. DLADTO produces a series of steel couplers including threaded rebar couplers, cold extrusion rebar couplers, and reducing couplers, with a complete range of sizes and specifications, capable of meeting various needs while maintaining reliable quality.

When choosing steel connectors for construction projects, contractors and engineers should carefully consider the advantages and disadvantages of each method to ensure the safety and durability of the overall structure. By understanding the differences between threaded rebar coupler and cold extrusion rebar coupler connections, construction professionals can make informed decisions to achieve efficient and reliable steel connections in their projects.
