Our Sheet Metal fabrication Technology
Cutting
Sheet metal is cut into the desired shape and size using various methods including shearing, laser cutting, plasma cutting, or water jet cutting. Precision cutting is essential to ensure accurate dimensions and smooth edges.
Bending
The sheet metal is bent into specific angles and shapes using press brakes or other bending machines. This process requires precise control of force and angle to achieve the desired bend without causing deformation or cracking.
Forming
Additional forming processes such as rolling, punching, or stamping may be used to create complex shapes, contours, or features on the sheet metal.
Welding
Welding is used to join multiple pieces of sheet metal together. Common welding techniques include spot welding, MIG welding, TIG welding, and seam welding. Welded joints must be strong and durable to withstand the intended application.
Finishing
After fabrication, the sheet metal may undergo surface treatments such as painting, powder coating, or plating to enhance its appearance and protect it from corrosion.
Assembly
The fabricated components are assembled together to create the final product. This may involve fastening, riveting, or welding the components together.
Our Common Processing Row Materials
Aluminum
Lightweight with good thermal conductivity, often used in manufacturing aerospace components, automotive body panels, and electronic product enclosures.
Stainless Steel
Recognized for its corrosion resistance and excellent mechanical properties, suitable for producing kitchenware, medical equipment, and architectural components.
Galvanized Steel
Steel coated with a layer of zinc for corrosion resistance, commonly used in outdoor equipment, pipelines, and structural construction.
Alloy Steel

Cold-rolled Steel
Known for its good formability and strength, commonly used in manufacturing automotive parts, machinery components, and furniture.
Copper
Known for its excellent electrical and thermal conductivity, commonly used in manufacturing electronic components, communication equipment, and decorative items.
Our Surface Finishing
Grinding and polishing
Improving the smoothness and appearance of the metal surface through grinding and polishing techniques.
Spray Painting
Applying protective or decorative coatings using spray painting techniques.
Sandblasting
Using high-pressure blasting to remove oxide layers and impurities from the metal surface, improving surface roughness.
Heat treatment
Changing the structure and properties of the metal by heating and cooling, such as quenching, tempering, etc.
Painting
Including electroplating, galvanizing, chromium plating, etc., depositing another metal or alloy onto the metal surface to enhance its properties or appearance.
