Steel 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.
For technical drawings and 3-D models, click on a part number.
Rails have bolt holes on all four sides. Connect multiple rails with brackets or slide one length of rail into the next larger size and bolt together using curved-bolt or locking-pin connectors. Select connectors based on the larger size rail in the connection.
Zinc-plated steel rails resist corrosion better in wet environments than plain steel rails.
Galvanized steel rails resist corrosion better in wet environments than zinc-plated steel rails.
Steel rails are lightly oiled.

Surface brackets connect rails. These brackets do not have mounting holes already drilled, so you can drill holes where you need them or weld the brackets in place.
Zinc-plated steel brackets are more corrosion resistant in wet environments than powder-coated steel brackets.
Galvanized steel brackets have better corrosion resistance in wet environments than zinc-plated steel brackets, and they can be used outdoors.
304 stainless steel brackets are more corrosion resistant than galvanized steel brackets. They also have good chemical resistance.

Mounting feet have a flange to attach rails to floors, walls, and ceilings.
Telescoping Weld-Together Rails
Create posts of varying lengths. To telescope rails, slide one length of rail into the next larger size rail (for example, a 1 3/4" height rail fits into a 2" height rail and a 3/4" dia. rail fits into a 1" dia. rail). Weld the rails together at the desired length to create strong structures. These rails are not compatible with weld-together framing and fittings.
Carbon steel rails are lightly oiled.
Galvanized carbon steel rails have good corrosion resistance in wet environments and can be used outdoors.
