Sheet Metal Fabrication Process

laser cutting service

Laser cutting

Laser cutting is a thermal cutting process that uses high-power laser to cut metals and achieve high-quality results. Applicable for all industries.

Cutting area: Up to 4000 x 6000 mm

Material thickness: Up to 50 mm

Laser sources: Up to 6 kW

Repeatability: Ps: +/- 0.05 mm

Position accuracy: Pa: +/- 0.1 mm

Plasma cutting

CNC plasma cutting is a widely used sheet metal technology, it is especially suitable for cutting thicker sheet metals.

Cutting area: Up to 4000 x 6000 mm

Material thickness: Up to 50 mm

Cutting area: Up to 4000 x 6000 mm

Maximum material thickness: Up to 50 mm

waterjet cutting

Waterjet cutting

Waterjet cutting is quite different with other cutting methods for its non-thermal feature. It is especially useful for cutting very thick metals, including steel.

Maximum cutting area: Up to 3000 x 6000 mm

material thickness: Up to 300 mm


Bending is a common sheet metal forming method used to shape steel, stainless steel, aluminium parts after cutting process.

Metal folding capacity: Up to 200 tons

Maximum bending length: Up to 4000 mm

Maximum thickness: Up to 20 mm



Sheet metal welding process fuses two or more metal parts together with high heat to realize complex structure or requirements.

Sheet Metal Materials

Sheet metal fabrication has relatively less options for materials, usually aluminum, copper, and steel. Please check the materials GUAN SHENG provides for sheet metal services.


Commercially, aluminum is the most sought after material for sheet metal fabrication. Its popularity is due to its adaptive qualities and its high thermal conductivity and low resistance rates. Compared to steel—another common sheet metal material—aluminum is more cost-effective and has a higher rate of production. The material also generates the least amount of waste and can easily be reused.

Copper is a broadly used sheet metal fabrication material in many industries as it offers good malleability and ductility. Copper is also well suited for sheet metal fabrication because of its excellent heat conduction properties and electrical conductivity.

Steel offers a number of beneficial properties for industrial applications, including rigidity, longevity, heat resistance and corrosion resistance. Steel sheet metal is ideal for producing complex designs and parts that require extreme precision. Steel is also cost-efficient to work with and has excellent polishing properties.

Stainless Steel

Stainless steel is the low carbon steel that contains a minimum of 10% chromium by weight. The material properties associated with stainless steel have made it a popular metal within a broad range of industries, including construction, automotive, aerospace and more. Within these industries, Stainless steel is versatile and is an effective choice for many applications.

Sheet Metal Finishing Options

The surface finish available for sheet metal fabrication depends on which material and what is the part used for. The finishing options GUAN SHENG provide for sheet metal services are listed below:


Anodizing improves corrosion resistance, enhancing wear resistance and hardness, and protecting the metal surface. Widely used in mechanical parts, aircraft, and automobile parts, precision instruments, etc.

Clear, black, grey, red, blue, gold.
Smooth, matte finish.
1.8 μm to 25 μm (0.00007")

Bead Blasting

Bead blasting results in parts with a smooth surface with a matte texture. Used mainly for visual applications and can be followed by other surface treatments.

ABS, Aluminum, Brass, Stainless Steel, Steel
Sa1, Sa2, Sa2.5, Sa3
Cosmetic parts

Powder Coating

Powder coating forms a durable, wear resistant and corrosion resistant layer on the surface of parts. Powder coating can be used to apply colors to parts and is compatible with any metal.

Aluminum, Stainless Steel, Steel
Black, any RAL code or Pantone number.
Gloss or semi-gloss
Vehicle parts, household appliances, aluminum extrusions

Electroplating can be functional, decorative or corrosion-related. Many industries use the process, including the automotive sector, in which chrome-plating of steel automobile parts is common.

Aluminum, Steel, Stainless Steel
Plate type:
Tin, Nickel, Electroless Nickel
Smooth, glossy finish
Electrical connections, jewelry, radiation shields
Galvanizing, nickel plating, tin plating, passivation
