Plain gratings are designed with smooth surface which is different from serrated grating. They share high strength-to-weight ratio and self-cleaning properties and are extensively engaged by trench covers, secure fencing, handrails, flooring and stair treads and other applications for their easy installation, recyclability and durability.
Plain gratings manufactured by aluminum, mild steel and stainless steel often take the place of solid metal plates. On one hand, metal gratings save a lot of original cost; on the other hand, debris, water, snow and other small things can get through the bar spacing.
Note: If skip-resistance is urgently needed, you should order serrated grating.
