183.5×65mm Heavy-Duty Weld-On Hinge

This hinge is ideal for heavy machinery, industrial enclosures, marine doors, equipment cabinets, and metal gate systems. Because of its reinforced stainless steel structure, it supports demanding industrial and outdoor applications.

The 4mm thick stainless steel construction improves load capacity, structural stability, and long-term durability. As a result, the hinge performs reliably under heavy door weight and frequent operation.

The hole version allows additional mechanical fastening during installation, while the no-hole version supports direct welding for a cleaner appearance. Therefore, users can choose the mounting style that best fits their equipment design.

Weld-on hinges provide stronger and more permanent installation compared with standard screw-mounted hinges. In addition, they help improve structural integrity for machinery doors and heavy metal enclosures.

Yes. Stainless steel offers strong corrosion resistance against moisture and harsh environmental exposure. Consequently, the hinge works well for marine equipment, outdoor machinery, and industrial applications exposed to humidity or weather conditions.
