Documentation - Molded Grating - .75x.75xh1.5-minimesh
0.75 × 0.75 × H 1.5" (19 × 19 × H 38 mm) Minimesh
Product Overview
This 1.5-inch-deep molded FRP minimesh grating combines a pedestrian-friendly 0.75-inch top opening with a 1.5-inch structural base mesh. Its greater depth provides increased stiffness, load capacity, and span capability compared with shallower minimesh profiles, while the smaller surface openings help reduce the passage of tools, debris, and other small objects.
Common uses include industrial walkways, elevated platforms, trench covers, mezzanines, maintenance access areas, docks, marine facilities, water and wastewater treatment plants, food-processing facilities, chemical-processing environments, and applications requiring corrosion resistance, drainage, and enhanced structural performance.

Actual Panel Sizes and Tolerances
Minimesh panels are supplied closed-web, with all perimeter cells fully closed. Because each molded cell has a 1.50-inch pitch and a perimeter web of approximately 0.27 inch is added, the finished size equals the nearest whole-cell multiple plus the outer web.
For example, a nominal 4 ft × 8 ft closed-web panel is finished at approximately 48.27 in × 96.27 in. When exact nominal edges are required, specify open-edge trim. Open-edge trimming exposes the perimeter cells.
