A collaborative method that leverages the advantages of mechanical joints and welded joints!
The "3CW Reinforced Steel Welding Joint Method" is a new joint technology developed by a team of specialists in technical development. It achieves a good joint for high-strength rebar, which is considered difficult with current rebar joints. Additionally, it enables full-circle ultrasonic inspection, which was previously impossible, ensuring the provision of high-quality joints. 【Features】 ■ Utilizes high-quality bar steel (SNR490B) for excellent weldability ■ Joins high-strength rebar (SD490) and bar steel (SNR490B) using friction welding ■ Supports the skills of welding technicians for welding between bar steels ■ On-site rebar assembly uses fusion welding between bar steels ■ Guarantees high strength based on the cross-sectional area of the bar steel (SNR490B) *For more details, please refer to the catalog or feel free to contact us.
