Polymer composite drainage grate compliant with EN124 load standards, crafted from high-performance polymer composite material for superior corrosion and weather resistance. Featuring anti-slip texture and optional round/slotted drainage holes, it offers anti-theft, non-conductive and low-maintenance performance, ideal for municipal roads, landscapes and residential drainage systems.
Will never rust or degrade from exposure to moisture,fertilizers,de-icing salts,or mild chemicals,ensuring a long,maintenance-free life.
Significantly lighter than equivalent steel or cast iron grates,reducing installation risk,labor time,and cost—no heavy machinery needed.
The Grating style maximizes water intake for high-flow areas. The Round Hole style minimizes clogging from leaves and debris,ideal for landscaped zones.
High-quality polymer composite offers excellent toughness,withstands UV exposure without significant fading,and won't become brittle in cold temperatures.
A safe choice near electrical equipment or in areas where spark resistance is a priority,eliminating galvanic corrosion risk.
Provides superior corrosion resistance and good load capacity at a lower initial and lifetime cost compared to coated metal alternatives.
