Bar Grating Steel Grates 10"X24"X1.25" Heavy Duty Steel Floor
What Is Steel Bar Grating?
Steel Bar Grating, also known as welded steel bar grate, is extremely strong and durable for all load bearing applications and is primarily used for pedestrian and light vehicle traffic.
Steel Bar Grating is available in a variety of bearing bar spacing and thickness depending on applications and load requirements. Available in either smooth top or serrated for slip resistance.

Bar Grating, Metal Grating, is an open grid assembly of metal bars, in which the bearing bars, running in one direction, are spaced by rigid attachment to cross bars running perpendicular to them or by bent connecting bars extending between them, which is designed to hold heavy loads with minimal weight. It is widely used as floors, mezzanines, stair treads, fencing, trench covers and maintenance platforms in factories, workshops, motor rooms, trolley channels, heavy loading areas, boiler equipment and heavy equipment areas, etc.
Frequently Asked Questions
Can steel grating support heavy machinery?
Yes, with proper design, steel grating can support industrial equipment.
How is steel grating installed?
It can be mounted on support frames, welded, bolted, or anchored depending on the structure.
Can steel grating be cut on-site?
Yes, using cutting tools suitable for steel, such as angle grinders or plasma cutters.
What is the difference between welded and pressed steel grating?
Welded grating has bearing and cross bars welded; pressed grating uses pressure-locked joints.
Is maintenance required for steel grating?
Minimal maintenance is needed; periodic cleaning and inspection are recommended.
Can steel grating resist chemicals?
Stainless steel or coated grating offers resistance to many chemicals.
