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.

Low-Carbon Steel 90° Angles
- Yield Strength: 36,000 psi
- Hardness: Not Rated
- Heat Treatable: See Table
- Max. Hardness After Heat Treatment: Not Rated
- Fabrication: Hot Rolled
- 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 frames, supports, and edge protectors. These 90° angles meet either ASTM A36 or EN 10025-2 standards for performance and quality.
Heat treatable steel can be surface hardened for added wear resistance.

Rebar
Reduce the chance your concrete will crack from expansion and contraction and other tensile stresses. Concrete inherently stands up to high compressive loads—adding this rebar strengthens it against pulling forces as well. The rebar's surface is textured; poured concrete fills in the gaps between those ridges to create a strong bond.
Carbon steel rods expand and contract at the same rate as concrete, further reducing the risk of cracking. In addition to using them in structural applications such as reinforcing concrete, cut, bend, and weld them onsite for applications like rebar fencing and shelving.
