Built for the most demanding environments,this hybrid system delivers uncompromising performance. The resin concrete channel provides a tough,monolithic trough with exceptional resistance to chemical attack,abrasion,and thermal shock. It is capped with a heavy-duty welded steel bar grating,designed for maximum open area to facilitate rapid drainage while supporting extreme wheel loads from forklifts and heavy vehicles. This combination creates the ultimate drainage workhorse for factories,logistics hubs,and industrial facilities.
The welded steel bar grating provides superior structural integrity,capable of supporting the heaviest industrial and vehicular loads (up to Class F900).
The resin concrete channel is impervious to oils,solvents,acids,and salts,while its smooth interior minimizes friction and wear.
The high percentage of open area in the steel grating allows for rapid intake and passage of large volumes of water,preventing surface flooding.
Combines the chemical immunity of resin concrete with the unmatched mechanical strength and impact resistance of steel for decades of service.
Optional serrated bar grating provides excellent traction for personnel and vehicles,enhancing safety in wet industrial conditions
Offers the best balance of extreme performance,longevity,and lower lifetime maintenance costs compared to traditional concrete or all-metal systems.
