Integrated Pressure Welding Forming
Fully automatic mechanical pressure welding process is adopted to make the bearing bars and cross bars closely integrated. The welding points are full and firm, with uniform force, no virtual welding or missing welding, ensuring the overall flatness and structural integrity of the finished treads.
Precision Finishing & Size Calibration
All finished treads are precisely cut and sized according to industrial standard dimensions, with rounded edge trimming to prevent scratching. Reserved installation bolt holes are accurately positioned to ensure seamless matching with industrial stair support structures and realize rapid assembly.
Dedicated Anti-Slip Profiling Processing
For outdoor special anti-slip models, numerical control precision serrated processing is carried out. The anti-slip teeth are evenly distributed with moderate friction strength, which not only ensures safe anti-slip walking but also avoids excessive wear on pedestrian shoes and equipment.
Overall Hot-Dip Galvanizing & Quality Inspection
After the finished product is formed, the whole piece is hot-dip galvanized to form a uniform and dense anti-corrosion layer. Each batch of products undergoes load testing, anti-slip performance detection, salt spray corrosion testing, and size calibration to fully comply with OSHA industrial stair safety standards.
