What is sheet metal fabrication?

Sheet metal fabrication uses laser cutting, turrets, brake presses, and panel bending to form parts and components with uniform wall thickness through cutting, punching, and bending. Sheet metal fabrication or forming allows for a high amount of flexibility during a product’s design, prototype, and production ramp.

With absolutely no marginal tooling investments, products can swiftly relocate from prototyping to production. It is more cost-effective than CNC machining.

Sheet Metal Fabrication Materials

20+ popular materials for sheet metal fabrication machining. We can help source for you if your need is not listed.


Aluminum is a pure metal that is easily alloyed with small amounts of other materials like copper, manganese, silicone, or magnesium. It is not magnetic or combustible and has good electricity conductor. It offers good corrosion resistance and is easy to form and process. It is often used because of its weight.

Avialable: 5052, 1060, 6061, 6063

Stainless Steel

Stainless steel is a wide range of sheet metals that contain at least 10% chromium. Standard or austenitic stainless steel is very common and does not require heat during the manufacturing process. These alloys are corrosion resistant, forming and welding friendly. Many different grades are available.

Avialable: 201, 304, 316


Brass is an alloy of zinc and copper. It has excellent electrical conductivity, and is easy to machine. With low friction properties and gold-like appearance, brass is commonly used in the architecture sector to manufacture gears, locks, pipe fittings.

Avialable: H65, H62


Copper can be shaped into many different shapes. Copper is a metal with good strength and hardness. It also has superior thermal and heating conductivity and corrosion resistance. It is therefore a material that is valued for both its aesthetic and functional properties.

Avialable: T2

Spring Steel

Spring steel are primarily used to manufacture springs as the steel will return to its original shape after twisting or load bearing. Spring steel usually requires heat treatment to obtain the desired spring and rebound properties. Carbon steel can be used for little springs, but huge springs are best when an alloy is made use of.

Avialable: 65MN

Cold Rolled Steel(CRS)

Cold rolled steel is essentially hot rolled steel that has gone through an additional rolling process at room temperature.This additional processing produces a steel with closer tolerances and a broader range of finishes. The result is an increase in strength by as much as 20% compared to hot rolled steel.

Avialable: SPCC,SAPH

Hot Rolled Steel(HRS)

Hot rolled steel is produced when steel is processed by a series of roll presses at temperatures over 1700°F. The procedure creates steel that is conveniently formed or formed into large pieces and is best-made use where resistances aren't as vital. HRS has good formability and weldability properties.

Avialable: Q235,45C

Cold Galvanized Steel

Cold galvanized steel has a zinc covering repainted to the steel surface area to shield it from deterioration. The coating will certainly supply both obstacle protection and a galvanic defense to help prolong the life of the product. It can be applied with brushes, rollers, sprayers, or through electro-galvanizing.. The paint includes special binders.

Sheet Metal Fabrication Finishes

Surface finishes are applied after fabrication and can change the appearance, surface roughness, hardness and chemical resistance of sheet metal components.

As Machined

Components as provided as cut, no additional therapy applied. Sharp edges are damaged and deburred for risk-free handling. For any type of crucial sides that need to be left sharp, please note and specify them in your drawings. For metals, as machined can be Ra 1.6 or Ra 3.2. For plastics, as machined usually refers to Ra 3.2.


Anodizing enhances aluminum parts' rust resistance, boosting wear resistance and firmness, and safeguarding the metal surface. Type II and Type III are both available. For Type II, it can be in different colors, clear, black, red, and gold are most usual. Type III layer is thicker and is better put on resistant and deteriorating immune.

Spray Coating

Spray coating normally includes the application of spray painting, powder coating, and Teflon coating for different covering materials and technologies. Spray painting and powder finish can have rich shades like black, white, red, and others. For powder coating, it can be glossy and matte. For spray painting, it can be shiny, matte, textured, metal.

Metal Plating

Electroplating is a surface treatment procedure that can enhance the deterioration resistance, hardness, conductivity, attachment, and decoration of sheet metal components. We offer vast layering options, gold plating, silver plating, zinc plating, copper plating, nickel plating, and chrome plating.

Mechanical Finishes

Mechanical finishing is a process that involves generation of different-looking surface textures on metal by brushing, tumbling, or bead blasting the surface. Its benefits lie in the aesthetic appeal and is also a great choice for covering and blending any imperfections or unwanted lines and marks that might appear as a result of the manufacturing process.

Part Marking

Part marking is an economical way to add logos or custom-made text to your layouts and is frequently used for custom components. Laser engraving and silk screening are 2 cost-effective techniques that permit better versatility with your design. They are an excellent alternative for logos and lettering that are tough to create with manufacturing alone.

Heat Treatment

Heat treatment is a material processing technique that involves heating and cooling materials to adjust their properties, including hardness, strength, toughness and more, to meet specific engineering or manufacturing requirements. Spring steel 65Mn must undergo heat treatment to acquire elasticity. S7 harnness can be increased by heat treatment.

Chemical Finishes

Chemical finishing includes chromate conversion gold, chromate conversion clear, passivation, black oxide, adodine, electropolishing. Chemical finishing can remove blemishes from a part, alter its conductivity levels, extend its lifespan, and even increase its resistance to wear and corrosion of the sheet metal fabrication parts.
