LD-015 Stainless Steel Door Hinge Assortment | Factory Wholesale Supplier

This stainless steel door hinge assortment delivers a full spectrum of sizes and load ratings for residential, commercial and institutional door construction projects. Choose long-lasting 304 stainless steel for coastal, high-humidity areas, or cost-effective 201 stainless steel for dry inland interior applications, both resisting rust and corrosion for over 20 years of indoor service.

Built-in ball bearing hardware replaces traditional flat washers, enabling quiet, friction-free door movement certified for 100,000 open-and-close cycles without wear or permanent sagging. Four standard lengths ranging from 3-inch to 6-inch plus three plate thickness grades support door weights from 40kg up to 120kg per hinge pair. The removable hinge pin lets users lift off doors for maintenance or relocation without removing the whole hinge from door frames.

Every knuckle is precision CNC machined to a tight 0.05mm tolerance to guarantee aligned leaves and perfect pin fit. Customization services include laser logo engraving, bespoke surface finishes and unique hinge shape development, tailored for branded hardware wholesalers and construction contractors.
