Alloy Steel

Introduction to Steel

An alloy made up primarily of iron and carbon, steel is known for its high tensile strength and low costs. The combination of these characteristics has made it a ubiquitous material in the construction, infrastructure, automotive, maritime, tooling, manufacturing and defense industries, among others.

Surface Finishes for Your Choosing

Name	Description	Materials	Color	Texture	Link
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.

Electroplating	Electroplated coating preserves the surface of parts and resists rusts and other defects from causing decay by applying electric currents to reduce metal cations.	Aluminum, steel, stainless steel	n/a	Gloss or semi-gloss	Learn more
Polishing	Ranging from Ra 0.8~Ra0.1, polishing processes use an abrasive material to rub the part’s surface to make the shine more less shiny, depending on your requirements.	All materials	n/a	Smooth, glossy finish	Learn more
Painting	Painting involves spraying a layer of paint onto the surface of the part. Colors can be matched to a Pantone color number of the customer’s choosing, while finishes range from matte to gloss to metallic.
