Welded steel bar grating is the most popular type, due to its combination of strength, ease of installation and cost-effectiveness. See Welding Standards for more information. Applications include platforms, ventilation grates, stair treads and safety covers. The selection of welded grating products available include standard weld, close-mesh, railroad and heavy-duty.

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…
Riveted bar grating is primarily used for engineering applications involving wheeled equipment that transports rolling loads due to its resistance to buckling. Available in both aluminum and steel, this type of grating features reticulated bars that are riveted to the bearing bars. The reticulated bars provide the smooth surface that is essential for the safe, smooth passage of rolling equipment. Read more…
Heavy-duty bar grating provides maximum strength in order to accommodate heavier loads in industrial and commercial settings. Heavy-duty bar grating also has a long lifespan which makes 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…
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 cross bars 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…
Choosing the Best Material for Your Bar Grating Products
- Carbon Steel: Carbon steel provides an economical, high strength grating for use in most industrial and commercial applications.
- Aluminum: Lightweight, corrosion-resistant and non-sparking alloys make aluminum ideal for use in chemical, petroleum, hydro and food processing plants, water and waste treatment facilities; munitions plants and other volatile areas; aboard ships; etc.
- Stainless Steel: Stainless steel is ideal for use in caustic atmospheres where corrosion resistance and minimum carbide precipitation are important considerations. It is especially applicable for chemical, food and hydro processing areas.
