Precision Sheet Metal Fabrication Capabilities
With over 100 advanced machines, like laser cutters, bending machines, and welders, in our China-based network, we can supply any quantity of fabrication sheet metal parts, from low-volume prototypes to high-volume production. Our domestic fabricators and engineers provide precision and fast delivery.
Laser Cutting
Laser cutting uses a focused laser beam to cut, etch, or engrave materials, vaporizing or melting them for precise edges and complex patterns based on designer specifications.
Bending
Bending applies a force to a thin sheet of metal to shape it into various geometries, like U-shape, V-shape, or channel shape.
Welding
Welding is the process of joining two or more metal pieces using heat, pressure, or both to form a strong bond. It combines skill and precision to create durable, sturdy metal structures.
Punching
Punching uses a punch tool to create holes or shapes by forcing it through a die, cutting the metal with a shearing action for precise, clean results in fabrication.
Sheet Metal Enclosures
Custom sheet metal enclosures for protecting electronics and industrial components. Precision fabrication and assembly ensure tight tolerances, clean finishes, and reliable performance.
Stamping
Stamping uses dies and presses to shape flat metal sheets into different forms, creating complex, three-dimensional designs through cold-forming techniques.

Materials for Custom
Sheet Metal Fabrication
Aluminum’s lightweight, corrosion-resistant, and has a great strength-to-weight ratio, so it’s ideal for aerospace, automotive, and construction. It’s also easy to machine.
Subtypes: Aluminum 5052, Aluminum 5083
Brass is super malleable, corrosion-resistant, and has that gold-like look. It’s found in everything from decorative items to gears and valves.
Subtypes: Brass C27400, Brass C28000, Brass C36000
Copper’s known for its excellent electrical and thermal conductivity. It’s really ductile, making it perfect for electrical wiring, plumbing, and roofing.
Subtypes: Copper C101(T2) Copper C103(T1) Copper C103(TU2) Copper C110(TU0)
Steel’s super strong and durable, commonly seen in construction and heavy industries. You can mix it with other elements for enhanced hardness or corrosion resistance.
Subtypes: SPCC, Galvanized Steel (SGCC / SECC), Q235, Steel 1020
Stainless steel’s great for resisting corrosion, it’s strong, easy to clean, and maintains its shine. It’s used in medical devices, food processing equipment, and marine environments.
Subtypes: Stainless Steel SUS 304
