## Description

These folding hinges are constructed from solid cold-rolled steel plate with nickel plating on both sides for corrosion resistance and smooth operation. Reinforced welding points feature steel nail sealing to prevent joint failure, ensuring structural integrity under repeated use. Designed for heavy-duty applications, they support substantial loads without deformation or loosening. The hinge operates with a hard closure mechanism, where load-bearing occurs only when fully closed—approximately 85°—though optional shims can adjust alignment to achieve a true 90° closure. Installation requires precise marking, drilling, and screw fastening, followed by functional testing to confirm smooth opening and closing motion. Common applications include folding doors, portable tables and chairs, storage crates, display stands, and other collapsible furniture or fixtures where reliable, repeatable articulation is essential. The hinge’s compact profile and robust construction make it suitable for both indoor and sheltered outdoor environments without compromising performance over time.
