waterjet cutting

Waterjet cutting

Waterjet cutting is quite a different sheet metal service 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 and custom sheet metal prototypes after cutting process.

Metal folding capacity: Up to 200 tons

Maximum bending length: Up to 4000 mm

Maximum thickness: Up to 20 mm

The 4 parts look great and work very well. This order was to solve a problem on some equipment, so only the 4 parts were needed.

We were very pleased with your quality, cost and delivery, and will certainly order from you in the future. I have also recommended you to friends who own other companies.

The service at RapidDirect is phenomenal and Cherry has assisted us with great patience and understanding.

Great service as well as the product itself, exactly what we asked for and works amazingly. Especially considering the small details we were requesting. Good looking produckt.

Drew Mumaw

Excellent job by production being able to use grips for the anodizing bath instead of a hole in the center of the part.

Always quick and easy dealing with Tammy – great communication! We look forward to doing business with RapidDirect soon.

Rayner Moss

The motor tube was great, within tolerances and the finish was very nice. It was packaged very well and even though the box was clearly thrown around in transit, the contents were perfect.

The next time I need something machined I will definitely be coming to you.

Material Options for Sheet Metal Prototyping

Sheet metal fabrication has relatively less options for materials, usually aluminum, copper, and steel, but each material has a wide range of subtypes to select. Please check the materials RapidDirect provides for sheet metal services.


Commercially, aluminum is the most sought-after material for sheet metal manufacturing. 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.

101, C110

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 RapidDirect 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 is a type of coating that is applied as a free-flowing, dry powder. Unlike conventional liquid paint which is delivered via an evaporating solvent, powder coating is typically applied electrostatically and then cured under heat or with ultraviolet light.

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
