Introduction to Stainless Steel

Stainless Steel

Stainless steel, a type of low-carbon steel, possesses numerous advantageous qualities for industrial use. Typically containing a minimum of 10% chromium, stainless steel is a popular metal in various sectors such as construction, automotive, aerospace, and more. Its versatility makes it an ideal material for a wide range of applications in these industries.

Name Description
As Machined

As Machined

Coming out of the machine after machining, our parts are cleaned of any sharp edges and burrs while retaining marks. Without any added material, the part had a surface roughness of 3.2 μm (126 μin).

Band Blasting

Band Blasting

Band blasting cleans the surface of any impurities and peels coating through the propelling of blast media streams over the parts.

Anodizing

Anodizing

To increase surface hardness and dissipate heat, we use anodizing techniques to enhance the look of parts and blend well for painting and priming.

Electroplating

Electroplating

Electroplating reduces metal cations in the electrolyte solution, producing a metallic coating on a metal surface. This process can be used for purposes of corrosion and wear resistance, as well as for decorative purposes.

Polishing

Polishing

Working on metal and hard plastics, our polishing uses highly efficient machinery to get our parts between Ra 0.8~Ra0.1 for a cleaner surface.

Powder coating

Powder coating

We apply a thin layer of protective polymer with the corona discharge phenomenon to give our part a lasting finish that protects from impacts and prevents wearing down.

Brushing

Brushing

Our brushing technique uses abrasive belts over the material to create diverse patterns that match the parts’ structure and color.

Painting

Painting

Painting involves Spray droplets can be dispersed uniformly or in fine amounts to cover a wide surface area and bring out greater color to the part.

Black Anodized

Black Anodized

Adding layers to metallic surfaces like steel, our black anodized technique improves appearance while maintaining durability.

Alodine

Alodine

We use chromate conversion coating or alodine to protect aluminum and other materials from corrosive elements, usually done before priming and painting parts.

Laser Carving

Laser Carving

Helpful in brand recognition or parts organization, we use laser carving that applies various printing methods during full-scale production to quickly embed barcodes, lettering and logos on the parts.
