Steel grating raw panels are the flat, unprocessed versions of steel grating, often used as a base material for creating finished products such as walkways, stair treads, trench covers, and various other industrial applications.
These panels are typically made from carbon steel, stainless steel, or galvanized steel and come in various sizes, thicknesses, and load-bearing capacities.
Bearing bars: These are the main support bars that run parallel to the length of the panel. They provide the strength and load-carrying capacity.
Cross bars (or cross rods): These bars run perpendicular to the bearing bars and help to hold them in place, creating the grid pattern. They also add stability to the panel.
The raw panel itself is often cut to standard sizes or custom dimensions based on the end user's requirements. Afterward, it may undergo additional processes such as galvanizing (coating with zinc) or painting for corrosion resistance, or it might be welded or machined to meet specific design needs.
