About Aluminum

Yield Strength: 36,000 psi
Hardness: Not Rated (Medium)
Heat Treatable: See Table
Max. Hardness After Heat Treatment: Not Rated
Specifications Met: See Table

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 fixture clamps, mounting plates, and spacers. Some of these angles can be surface hardened with heat treating.

Anodized Architectural 6063 Aluminum 90° Angles

Yield Strength: 16,000 psi
Hardness: Brinell 60 (Soft)
Temper: T5
Fabrication: Extruded
Specifications Met: ASTM B221

The anodized coating on these 90° angles forms a bond with the aluminum surface to improve wear and corrosion resistance. Often called decorative anodize, it provides a uniform finish that readily accepts paint and adhesive. More corrosion resistant and easier to form than multipurpose 6061 aluminum, 6063 is primarily used for exterior railings, decorative trim, and door frames.

Easy-to-Form 6060 Aluminum

Yield Strength: 21,000 psi
Hardness: Brinell 65 (Soft)
Temper: T66
Fabrication: Extruded

Easier to bend and shape than 6061 aluminum, this aluminum is good for framing, cross sections, and structures in construction and marine industries. It’s corrosion resistant as well as easy to machine and weld. It can also be anodized to create a durable, decorative finish.

Hoist Trolleys

Transport hook-mount hoists along a beam.

Style B is rated for metric tons.

Trolleys with screw adjustment can be adjusted to fit your beam more quickly than trolleys that use spacing washers.

Warning: Never use to lift people or items over people.
