Zinc-Galvanized Low-Carbon Steel Sheets and Bars
These sheets and bars are zinc galvanized for good corrosion resistance. 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.

Flat and L-Shaped Bolt-Together Framing and Fittings
Rails are drilled with consistently spaced holes for multiple mounting options that do not require machining. Use this bolt-together framing to build guards, tables, and racks.
Zinc-plated steel rails are more corrosion resistant in wet environments than powder-coated steel.
Bracket fastener sets are required to connect brackets to rails.
