Welded Steel: see load table

Always-in-stock welded steel bar grating is the most popular type, due to its combination of strength, ease of installation, and cost-effectiveness. Applications include platforms, ventilation grates, stair treads, and safety covers. The available welded grating products include standard weld, close-mesh, railroad, and heavy-duty. Read more about welded bar grating.

Press-Locked: see load table

Press-locked grating features a system of perpendicular interlocking bars that provide a smooth, clean look. This makes it perfect for architectural applications where aesthetic sensibilities are of utmost importance. Press-locked grating can be produced from carbon steel, stainless steel or aluminum. Its surface can be treated by galvanizing, painting, or powder coating. Read more about press-locked grating.

Heavy-Duty: see load table

Heavy-duty bar grating provides maximum strength to accommodate heavier loads in industrial and commercial settings. It also has a long lifespan, making it ideal for demanding tasks over a long period of time. Standard widths are 2′, 3′, and 4′ in 20′ lengths. Standard bearing bars are 1/4″, 5/16″, and 3/8″ thick. Bars range from 1″ to 8″ deep. Read more about heavy-duty bar grating.

Aluminum: see load table

Swage-lock aluminum bar grating offers a lightweight alternative to heavier steel grating. It is manufactured with either “I” or rectangular bearing bars that are permanently locked to the crossbars via a swaging process, a technique that reshapes the rods. I-bar swage-locked is lighter weight and less costly than a rectangular bar grating with the same bar thickness. Read more about aluminum bar grating.

Bar Grating Uses

Uses and Applications

• Flooring
• Stairs, stair treads, and crossover platforms
• Sewage drain covers, manhole covers, forklift traffic, and loading ramps
• Racks and shelving
• Catwalks and crossover platforms
• Fire escapes, light guards, and loading ramps
• Mezzanines and platforms
• Infill panels
• Vessel internals and catalyst support grids
• Bridge sidewalks and bridge decking
• Architectural uses like building facades or partitions
• Security screens in residential and commercial buildings

Bar grating has a vast amount of uses ranging from flooring and stairs to bridges and sewage drain covers. It is a smart choice for flooring and stairs in work areas where slipping and falling are a major concern, such as industrial plants, wastewater treatment facilities, or manufacturing operations. The open design makes bar grating the best option for areas that require the passage of light. It also works well for projects that require fast, easy fabrication and installation.

Furthermore, metal bar grating often provides the best solution for situations requiring a high strength-to-weight ratio.

When caustic atmospheres are encountered, or when
corrosion resistance and/or minimum carbide
precipitation are essential considerations, stainless
steel grating is the answer. The longer lasting
capabilities of stainless steel under these special
conditions make it an economical selection over the
long term. Shot blasting or wire brushing should be avoided since
these operations can cause iron contamination which,
if not removed, will cause rusting and discoloration of
the surface. Such contamination can be removed by
passivation. Electro-polishing leaves a passive surface.
The swage-locked and presslocked processes will
not show discoloration due to welding. It is ideal for use in food processing areas, breweries,
bottling plants, dairies and meat packing plants. Stainless
steel can also be used in power plants, sewage treatment
plants, pumping stations and hydrocarbon processing
facilities where various caustic environments are normal.
It also has application in shipboard and building industries
where saline solutions or atmospheres are present. Unless otherwise specified, stainless steel grating
shall have a mill finish as fabricated. "As fabricated"
means as fabricated in our shop without a subsequent
finishing operation. Stainless steel will show some
discoloration around the joints due to welding
Finishes available to remove discoloration include
sand blasting and electro-polishing, the latter being
used where bright finish is desired.
