Many ordinary aluminium and low-carbon-steel mounting brackets suffer from insufficient hardness, easy deformation under heavy-load operation, coarse machining burrs and residual surface dust. The inaccurate positioning holes will lead to assembly looseness and short-term service-life failure for your automated-equipment fixtures.

Our custom alloy-steel L-angle bracket is manufactured via one-piece five-axis CNC machining. Every mounting hole, locating slot and engraved part-marking is precisely processed. We remove all surface dust and machining debris, delivering uniform cold-grey silver fine-brushed metal finish. 4140 alloy-steel material delivers outstanding tensile strength, wear-resistance and impact-resistance, perfectly suited for long-time heavy-duty industrial fixture installation.
