LD-180 SUS304 Stainless Steel Door Hinge 4 Inch | Wholesale Supplier

The LD-180 SUS304 Stainless Steel Door Hinge is a premium door mounting component engineered for reliable, long-lasting door operation in residential, commercial, and institutional applications. Manufactured from SUS304 grade stainless steel, the hinge offers excellent corrosion resistance even in humid, coastal, and high-moisture environments where standard carbon steel hinges would rust and degrade. The 4 inch (100mm) open width provides adequate support for standard residential doors weighing up to 25kg, while the heavy-duty 2.5mm leaf thickness ensures structural rigidity under repeated opening and closing cycles. Ball bearing construction between the hinge knuckles reduces friction for smooth, quiet operation and extends hinge life by minimizing wear at the pivot point. Available in both 3-hole and 4-hole configurations to accommodate different door frame and door edge mounting preferences. The 3-hole pattern suits standard residential lightweight doors while the 4-hole pattern provides additional fastening security for heavier commercial doors. Each hinge ships with matching stainless steel mounting screws for a clean, unified installation appearance. Available in satin stainless steel, polished chrome, matte black, and antique bronze finishes to coordinate with any door hardware set. Whether installing residential interior and exterior doors, hanging commercial building entry doors, mounting kitchen cabinet doors, replacing bathroom door hinges, outfitting office partition doors, or installing garden gates, the LD-180 stainless steel hinge delivers professional-grade performance.
