About Us

Factory Facilities

Precision Manufacturing Equipment

Slitting Cutting: We utilize advanced slitting cutting technology to prevent defects commonly associated with traditional flame cutting (such as edge unevenness, cracks, unsmoothness, or slag issues).

Laser Cutting: Greatly improves cutting accuracy, aesthetics, and product alignment, eliminating component deformation and welding porosity.

3D H-Beam Drilling Machine: Realizes three-directional H-beam drilling (web and flange) simultaneously, improving hole-making accuracy.
