FRP grating has a variety of options in terms of specifications and sizes. The thickness is commonly between 25mm and 75mm, such as 25mm, 30mm, 38mm, 50mm, 65mm, 75mm and other different specifications. There are differences in the load-bearing capacity of gratings of different thicknesses. Generally, the larger the thickness, the stronger the load-bearing capacity. The apertures (grid sizes) are also varied, with common sizes of 19mm×19mm, 25mm×25mm, 30mm×30mm, 38mm×38mm, 50mm×50mm, etc. Smaller apertures are more suitable for preventing small objects from falling, while larger aperture grilles are used in some scenarios where ventilation and drainage requirements are high and there is no need to prevent small objects from passing through. In terms of sheet size, it is generally produced and sold in the form of a whole sheet. Common whole sheet sizes include 1220mm×3660mm, 1000mm×4000mm, 1220mm×2440mm, etc. In actual applications, it can be cut and spliced as needed to meet the different installation site size requirements.
