    Multipurpose 304 Stainless Steel I-Beams

    Image of Product. Front orientation. Stainless Steel. Multipurpose 304 Stainless Steel I-Beams.
    I-beams are lighter weight than H-bars, but they're not as strong. Use them when weight is a concern. From cookware to chemical-processing equipment, 304 stainless steel is a good all-around choice for a wide range of applications. It maintains its corrosion resistance in temperatures up to 1500° F.

    Multipurpose 304 Stainless Steel H-Bars

    Image of Product. Front orientation. Stainless Steel. Multipurpose 304 Stainless Steel H-Bars.
    H-bars have larger flange widths and thicknesses than I-beams, so they’re stronger and carry heavier loads, yet also weigh more. From cookware to chemical-processing equipment, 304 stainless steel is a good all-around choice for a wide range of applications. It maintains its corrosion resistance in temperatures up to 1500° F.

    Corrosion-Resistant Hoist Trolleys

    Image of ProductInUse. Front orientation. Contains Annotated. Trolleys. Corrosion-Resistant Hoist Trolleys.
    Made of stainless steel, these trolleys won’t corrode as they move hoists in areas that are frequently washed down with cleaning chemicals. They’re often found in commercial kitchens, because the wheels are coated in a lubricant that’s NSF registered H1 for incidental contact with food.
    A mounting bar and eye give you flexibility when mounting your hoist. Remove the eye and mount directly to the bar when you need those extra couple inches of space. These trolleys fit a range of beam widths thanks to spacing washers that you can add or remove. Anti-drop plates prevent these trolleys from falling off your beam if the wheels become derailed.
    Warning: Never use to lift people or items over people.

    Style 1

    Style 4

    Attach strut channel to structural beams without welding or drilling. Since these mounts clamp into place, you can easily reposition them as your needs change.
    Style 1—Mounting plates grip the beam flange while the square U-bolts cradle the channel. Fasten these mounts with the included hex nuts. Use in pairs; weight capacity is per pair.
    Style 4—Clamp strut channel to beams from both sides. Mounts fit into the channel opening and require a bolt and a 1/2"-13 strut channel nut (not included) to secure. Use in pairs; weight capacity is per pair.
    304 Stainless Steel—The choice for wet and outdoor environments, these resist rust. However, they won't hold up to the harsh chemicals that 316 stainless steel can.
