Protective and Architectural Trench Drain Grates

A fundamental hardscape design element of any modern city is the drainage system, which protects against flooding by draining excess water away. Now, underground drainage systems are designed to cope with frequent storms where any excess water always travels along the planned drainage flow paths to prevent flooding. Drainage systems are carefully planned to factor in the impact the drainage system has on our natural rivers and creeks. We are preventing waste from being washed into rivers and seas.

At Jonite, our reinforced stone channel grates and trench grates have redefined the role of gratings and drain covers in the architecture industry. With Jonite channel gratings and trench gratings, outdoor drain covers are more than functional products — they become a cornerstone in your design. They can become design focal points, inviting the viewer’s eye to follow intricate patterns that open up into the building design.

Our Impressive Materials for Channel Drain Grates

Inspired by aesthetically pleasing stone castles built during the Middle Ages, our company sought to transform natural stone into grates. Our journey included seven years of extensive research and development before producing the world’s first reinforced stone grate for commercial use. We launched the durable and functional product in 1994 and continue to lead in the trench gate industry as the only provider of stone composite products that can compete with metal.

Our materials consist of advanced hybrid polymers and 95% natural aggregates. Using at least 30% recycled materials in manufacturing makes our products a sustainable choice. We carry globally recognized green building credentials, such as a Leadership in Energy and Environmental Design (LEED®) certification from the U.S. Green Building Council, for responsible, environmentally friendly use of materials.

With welded materials joined in the stone composite, our grates achieve impressive load-bearing strength and performance. The result is BS EN 124:2015- and 1433:2008 compliant, meeting international guidelines for standard application in areas with vehicles and pedestrians. Architects, developers and our other customers of hardscape design enjoy the contemporary or artistic patterns produced with customization.

Landscape architects have used our channel and trench drain grates for various purposes, such as outdoor drain covers, channel grating along driveways, storm drain grates and indoor applications. A perfect combination of aesthetics and functionality in Jonite products makes us the best choice. Some impressive advantages of our designs include the following:

  • Temperature control: Jonite absorbs much less heat than traditional ferrous gratings, making it a more comfortable material around the house and in children’s playgrounds.
  • Electrical insulation: Dielectric properties equivalent to porcelain make our products an excellent electrical insulator —  a significant plus point in times of tropical thunderstorms.
  • Slip resistance: The rough and naturally matte surface meets international classifications as a slip-resistant safety feature for hospitals and schools.
  • Rust and corrosion resistance: Unique properties make our products suitable for indoor and outdoor applications, with rust and corrosion resistance providing durability and an ideal appearance.
  • Theft resistance: Our hardscape grates with stone materials don’t have the same raw material value of steel and cast iron scraps, so they’re much less likely to be a tempting target for thieves.
