The grout rebar coupler is an advanced mechanical splicing system designed to connect reinforcing bars (rebar) through a full grouting connection method. This product is manufactured using specialized materials, high-precision production techniques, and strict quality control measures to ensure superior performance in structural applications. The production process integrates modern manufacturing technologies to achieve consistency, durability, and compliance with international construction standards.

Raw Material Selection

The manufacturing of grout rebar couplers begins with the selection of high-quality raw materials, which directly influence the product’s strength, corrosion resistance, and longevity.

Steel Alloy Composition: The coupler body is typically made from high-strength carbon steel or alloy steel, with precise chemical composition control to meet mechanical property requirements (e.g., yield strength ≥ 500 MPa, tensile strength ≥ 600 MPa).

Anti-Corrosion Treatment: To enhance durability, the steel undergoes hot-dip galvanizing, epoxy coating, or stainless-steel fabrication for applications in corrosive environments (e.g., marine or industrial structures).

Grout Material: The grout used for filling is a non-shrink, high-strength cementitious or epoxy-based material, ensuring optimal bond strength between the rebar and coupler.
