Stainless Steel (SS) heavy-duty pivot hinges are specialized hardware designed to support the weight of large or oversized doors from the top and bottom rather than the side. Because the floor bears the bulk of the door's weight, these hinges reduce stress on the door frame and allow for a sleek, minimalist aesthetic.

Core Specifications
Material: Primarily Grade 304 or 316 Stainless Steel. 304 is standard for interiors, while 316 is used for marine or high-corrosion environments.

Weight Capacity: Standard "heavy-duty" models typically support 100kg to 500kg (220 lbs to 1,100 lbs). Industrial versions can reach capacities of over 1,000kg.

Rotation: Most offer 360-degree rotation, allowing the door to swing in both directions (double-action) or be restricted to one side.

Mechanism: Often features a ball-bearing system for silent, friction-free movement.

Why Choose SS Heavy Pivot Hinges?
Frame Longevity: Unlike butt hinges that pull on the side jamb, pivot hinges transfer weight to the floor. This prevents the "sagging" common in heavy wooden or metal doors.

Durability: Stainless steel is resistant to rust, moisture, and heavy wear, making it ideal for high-traffic commercial areas or grand residential entrances.

Aesthetics: They enable "hidden doors" or frameless designs where the hardware is nearly invisible.

Security: Because the pivot is recessed into the door and floor/ceiling, it is much harder to tamper with or remove from the outside.
