Product Introduction
Spec Sheet

Basic Description

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.

Core Strengths

Total Corrosion & Chemical Immunity:

Will never rust or degrade from exposure to moisture,fertilizers,de-icing salts,or mild chemicals,ensuring a long,maintenance-free life.

Lightweight & Safe Handling:

Significantly lighter than equivalent steel or cast iron grates,reducing installation risk,labor time,and cost—no heavy machinery needed.

Two Purpose-Built Designs:

The Grating style maximizes water intake for high-flow areas. The Round Hole style minimizes clogging from leaves and debris,ideal for landscaped zones.

Durable & Impact Resistant:

High-quality polymer composite offers excellent toughness,withstands UV exposure without significant fading,and won't become brittle in cold temperatures.

Electrically Insulating & Non-Conductive:

A safe choice near electrical equipment or in areas where spark resistance is a priority,eliminating galvanic corrosion risk.

Cost-Effective Solution:

Provides superior corrosion resistance and good load capacity at a lower initial and lifetime cost compared to coated metal alternatives.

Installation and Maintenance

Installation
  • Ensure the supporting frame or channel is level and clean.
  • Simply place the lightweight polymer cover into position. No special tools are required.
  • For a secure fit,some models may include integrated clips or can be secured with standard fasteners.
IMaintenance
  • Remove leaves and debris from the surface periodically.
  • Grating Style: Rinse with water to clear slots.
  • Round Hole Style: Debris typically sits on top for easy sweeping.
  • The covers can be pressure-washed. No painting,rust removal,or sealing is ever required.
