Press-Locked: see stock list
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: see stock list
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: see stock list
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…
Aluminum: see stock list
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…

Bar grating has a vast amount of uses that range 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 is a major concern, such as industrial plants, waste water 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.
What’s more, metal bar grating often provides the best solution for situations that require a high strength-to-weight ratio.
Choosing the Best Material for Your Bar Grating Products
We feature high-quality metal bar grating made from aluminum and steel in numerous styles for a wide range of applications.
- 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 bar grating 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.
