Low-Carbon Steel I-Beams
- Yield Strength: 50,000 psi
- Hardness: Not Rated
- Heat Treatable: Yes
- Specifications Met: ASTM A992
Made of rigid low-carbon steel, these I-beams are often used in construction, framing, lifting, and hoisting applications. Also known as mild steel, low-carbon steel is the most commonly used material for I-beams. It deflects less under load than medium- or high-carbon steel and is less likely to crack from welding. These I-beams have rounded corners, and are also known as American Standard I-beams. They weigh less than low-carbon steel H-bars, but are not as strong.

Low-Carbon Steel H-Bars
- Yield Strength: 50,000 psi
- Hardness:
Inch sizes: Not Rated
Metric sizes: Rockwell B70 (Medium) - Heat Treatable:
Inch sizes: Yes
Metric sizes: No - Maximum Hardness After Heat Treatment: Not Rated
- Specifications Met:
Inch sizes: ASTM A992
Metric sizes: EN 10034
Made of stiff low-carbon steel to deflect less under load, these H-bars are commonly used in machine bases, construction, platforms, and frames. Because of its rigidity, low-carbon steel is the most commonly used material for H-bars. These H-bars are less likely to crack from welding than those made of higher-carbon steels, and easier to weld than I-beams because they have a straight flange instead of a radius flange. H-bars are stronger than I-beams, but also heavier.

Track for Overhead Beam Conveyors
Track provides the runway for trolleys in manual and powered systems.
Note: Not designed for building structural support.
For technical drawings and 3-D models, click on a part number.
Trolleys for Manual Overhead Beam Conveyors
Prevent excess wear on the track and trolley—only the wheels of these push trolleys come in contact with the beam. Trolleys can be installed anywhere along the beam.
Trolleys for Powered Overhead Beam Conveyors
Use with conveying chain to automatically move these trolleys along the beam. The two-bolt bottom connection keeps the trolleys from loosening during use.
Chain for Powered Overhead Beam Conveyors
Chain connects trolleys and guides movement along the track. It can be assembled and disassembled without tools, yet its design makes it difficult to disconnect while in use.

Hooks for Powered Overhead Beam Conveyors
Hooks allow items to rotate 90° degrees while suspended. They attach to trolleys with a bolt and nut.

Highway-Style Guardrails
These are the same guardrails you see along roadways.
Drive posts into the ground and then attach rails and end pieces to create a barrier.
Anchor bracket end pieces secure rails to concrete. They’re often used to mount rails on bridges and buildings.

Fork-Mount Lifting Adapters
Use these adapters to convert a forklift for vertical lifting. They have latch hooks to connect to the load.
Style C have L-shaped fork brackets that accommodate a pair of forks of any width.
Warning: Never use to lift people or items over people.

A bolt fastened with a nut and cotter pin makes these shackles more secure than screw-pin shackles. Also known as anchor and bow shackles, the wide body provides room to attach multiple connectors.
Galvanized steel shackles have a thick coating for corrosion resistance.
Note: Capacities listed are for vertical lifting only. As the lift angle changes from vertical, the amount of weight the shackle can lift is significantly reduced.

Rotating for easy positioning before a load is applied, these have a latch to ensure that rope, chain, and fittings won't separate from the hook when the load slackens. The hook opening accommodates large anchor points and allows chain to move freely through the closed hook.
Note: Capacities are for vertical lifting only.
