Stamped Sheet-Metal Hardware With Hinge Bracket Assembly and Circular Mounting Holes

A hinge bracket assembly with mounting holes positioned outside their true position tolerance cannot be bolted to its mating structure without elongating the holes; the mounting hole bolt circle determines whether the bracket aligns to the structure's existing bolt pattern and whether the hinge axis sits at the design angle relative to the panel it carries. Shanghai Hanshen (Shanghai, founded 1991) fabricates this hinge bracket assembly from stamped sheet metal with circular mounting holes using gantry milling, CNC milling, and boring and milling machining at their north of 30,000 m² Shanghai facility, with hole true position, bracket face flatness, and hinge bore alignment inspected to match your drawing during initial part approval. EN 1090 and ISO 3834 certifications cover structural execution and weld quality for elevator, railway, machinery, and contract manufacturing hinge bracket assembly applications. Attach your print specifying hole positions, hinge geometry, material grade, and surface treatment to request pricing from our Shanghai production team. The plant works across energy saving and environmental protection, energy storage, and logistics sectors.
