Certification

Our screws for building and commercial projects have obtained EU CE EN 15048-1 certification (SB screws). This means that our structural steel fasteners fully comply with the mechanical strength and safety requirements of the EU Building Regulation (CPR) and can be legally sold in the EU market and used in major steel structure projects.

Quality is the lifeline of fasteners. We follow the ISO 9001 quality management standard and have established a comprehensive and systematic quality control and continuous improvement mechanism from incoming materials, mold development, heading, thread rolling to finished product inspection, to ensure that every screw has high stability.

Our factory has obtained ISO 14064-1 carbon inventory certification, enabling transparent and digital management of greenhouse gas emissions during the screw manufacturing process. We are committed to providing global customers with green fastener products that align with low-carbon trends.

​We have implemented the ISO 50001 energy management system to optimize the energy efficiency of equipment in the plant area and reduce unnecessary energy waste, thereby ensuring process stability and fully implementing energy conservation and carbon reduction.
