Durable Cold Extrusion Press Rebar Splicing Coupler

Cold Extrusion Transition Press Coupler= cold extruded connection + reducing function, specifically designed for extruding and connecting reinforcing bars of different diameters, and it belongs to a large-diameter, heavy-duty, and highly reliable reducing joint.

Size: from 12mm to 40mm.

Meet the requirements of steel bars: HRB500/B500B/SD600/ASTM 75

Material: 16Mn  

▎Advantages：

• No threading is required, and the steel bars are not damaged. The connection is achieved through extrusion and interlocking. There is no need for threading, and it is not sensitive to the material and hardness of the steel bars.

• It has extremely high strength and a large safety margin. The joint strength far exceeds that of the parent material of the steel bars. It is highly resistant to earthquakes, fatigue, and impact.

• It truly realizes reliable connection of different diameters. One end can be pressed with a larger diameter steel bar and the other end with a smaller one. The concentricity is good, and the force is evenly distributed. It is much more stable than welded diameter changes.

▎Application & Installation Position

• Main reinforcement bars of columns with varying diameters from top to bottom.

• Preferred for super high-rise buildings, frame columns, and bridge piers. Large diameter, high-strength steel bars with varying diameters.

• Main reinforcement bars with varying diameters in the foundation, bridge piers, cap beams, and box girders of bridges, high-speed railways, subways, and tunnels. Key structures where threading and welding are not allowed.

• Heavy-load beams, transfer floors, structures with seismic grade one, and high-intensity seismic zones. Varying diameter parts in underground, water-adjacent, damp, and explosion-proof environments such as basements, pipe galleries, water tanks, and civil air defense projects.
