Galvanized Metal Structural Bracket

Custom-shaped metal bracket with an L-shaped 3D structure, designed for internal support or positioning connections in equipment. The base features a long mounting seat with countersunk holes at both ends for bolt fixation. The vertical side plate includes a large central round hole, multiple irregular slot holes, and circular through-holes. A right-angle flange extends from the side, creating a compact structure commonly used in mechanical transmission systems or fixture tooling as a link guide, limit stop, or load-bearing component.

This part requires strict control over the positional accuracy of multiple holes and the perpendicularity of bent edges. Center-to-center distance tolerances of mounting holes must ensure smooth assembly, while flatness is controlled to prevent warping of the mounting surface. The surface presents a uniform silver-white matte finish, likely achieved through electro-galvanizing or similar anti-corrosion treatment. During processing, burrs on sheared edges are removed and corners are deburred to prevent scratching mating parts or affecting subsequent assembly.

Leveraging our manufacturing experience in hardware and electronic components, we utilize 16T to 125T punch presses and shearing machines for blanking and stamping, followed by precision hole machining using bench drills. Vibratory tumbling and polishing machines enhance surface finish and edge consistency. Key dimensions are strictly inspected using dial calipers and height gauges. Please provide detailed drawings specifying material grades (e.g., SPCC cold-rolled steel or stainless steel), salt spray standards for surface treatment, and key mating tolerances to facilitate mold planning and lead time assessment.
