Additionally, the design minimizes the likelihood of stones and debris getting trapped in the grating, preserving the aesthetic appearance. Multiple slit holes are made in the special steel plate "patterned steel plate" on the top surface to balance drainage and strength. It has also been reported that the slip resistance exceeds that of conventional types. *For more details, please refer to the PDF document or feel free to contact us. 【Features】 ■ Safety (durable plate structure) ■ Reliability (non-slip patterned steel plate) ■ Strength (up to maximum T-25 load) ■ Lightweight (lighter than fine mesh) ■ Aesthetics (prevents clogging) ■ Damage prevention (distributes force over a surface)
