Steel

Cold-rolled steel

Everyday steel, paint it

Smooth, even grey steel — the everyday choice for brackets, enclosures and parts you will paint.

Rusts if left bare: add powder coat for outdoor use.

Hot-rolled steel

Structural, up to 1″ plate

Steel with a dark mill-scale skin, from thin sheet up to 1″ plate — the structural choice.

The mill scale is uneven and rusts bare: paint it.

Stainless steel

Stainless 304 · 2B mill

Aluminum, copper and brass

Aluminum 5052-H32

Light and rust-free

A third of the weight of steel, rust-free, and the aluminum alloy made for bending.

Softer than steel: scratches and dents more easily. Our aluminum gauges are BWG (14 Ga = 2.11 mm).

Aluminum 6061-T6

Structural: tube and plate

A third of the weight of steel and rust-free: the structural aluminum for tube frames and plates.

Cut and welded, never bent: 6061-T6 cracks in a tight bend, so bent parts go in 5052.
