An anodized coating forms a bond with the aluminum surface to improve wear and corrosion resistance.

More corrosion resistant and easier to form than multipurpose 6061 aluminum, 6063 is primarily used for exterior railings, decorative trim, and door frames.

Easier to bend and shape than 6061 aluminum, this aluminum is good for framing, cross sections, and structures in construction and marine industries.

While 2024 aluminum was initially designed for structural components in aircraft, it's now widely used when a high strength-to-weight ratio is needed. It offers similar performance to 7075 aluminum, but it’s not as strong.

Also known as mild steel, low-carbon steel is easy to machine, form, and weld. It's widely fabricated into parts that don’t require high strength, such as frames, supports, and edge protectors.

From cookware to chemical-processing equipment, 304 stainless steel is a good all-around choice for a wide range of applications.

Often called architectural bronze, 385 brass is easy to machine and has excellent formability when heated. It is typically used for handrails, ornamental trim, and hardware, such as hinges and lock bodies.
