Description
- Winwin drainage channels are made of polymer concrete. Using polyester resin as a bonding agent combined with mineral aggregates, polymer concrete offers exceptional compressive strength. It is highly load-resistant, durable, and long-lasting. Polymer concrete is non-flammable, frost-resistant, weatherproof, and resistant to diluted acids and alkalis.
- Stainless steel and galvanized steel wedge grating & trench covers are widely favored across global markets, featuring excellent durability and elegant appearance.
- These drainage Wedge grating cover meet EN 1433 and EN 124 standards, with load capacities from A15 KN up to C250 KN.

Winwin Polymer Concrete Channels are manufactured using resin as the bonding agent, combined with high-quality mineral aggregates. This makes polymer concrete an extremely compression-resistant building material that can withstand heavy loads while delivering exceptional durability and long service life.
Polymer concrete features non-flammable, frost-proof and excellent weathering resistance properties. It also offers reliable resistance to diluted acids, alkalis and various chemical substances, ensuring stable performance in diverse environments.Winwin Midddle Duty Drain Channel with Steel Grating System
