01 / General
-
Our heavy-duty trench grates are made from engineered stone that’s both strong and durable. All our trench grate covers are designed to handle heavy loads, whether it be vehicles or pedestrians. Plus, unlike some traditional trench grating, it has rust-resistant and corrosion-proof properties, so it’s built to withstand all weather conditions.
-
Jonite’s commercial trench grates are versatile enough to be used in everything from driveways, and poolside areas to public walkways and parks. All of our trench grating has different load ratings, making it suitable for use in heavy vehicle zones as well as pedestrianised areas.
-
Our trench grate covers are designed to handle vehicular loads and are compliant with BS EN124:2015 standards. Our load-rated drainage grates are available up to load class D400, making them suitable for heavy-duty applications such as commercial driveways, car parks, and other hardstanding areas.
-
The matte finish of our trench grating means it is naturally non-slip. We’ve conducted Pendulum and Ramp tests on all our trench grate covers to make sure they meet industry standards for slip resistance. With a class V on the Pendulum test and an R10 on the Ramp test, our drainage grates can handle most locations and applications.
-
We’re committed to building better places for people and our planet. We manage our energy, water, and waste with the future in mind. We also use at least 30% recycled aggregates in our stone grating products, which reduces carbon emissions by up to 80%. All our decorative grating is Singapore Green Building Product (SGBP) certified (4 ticks, leader). This means when you choose our stone trench grates, you can score additional points under the Functional Systems Criteria (Flooring, Ceiling, Roof, External Wall, Internal Wall and Door systems) and/or Singular Sustainable Products outside of Functional Systems Criteria.

All our trench grate covers come in a choice of standard styles, colours and textures. Plus, you can customise our commercial trench grates further and collaborate with us to create something totally bespoke. To find out more about custom trench grate design, visit our custom solutions page or get in touch.

All of our trench grates are Americans with Disabilities Act (ADA) compliant. Plus, our entire range of trench grate covers is capable of handling heavy loads and is ideal for spaces with strict BFA (barrier-free access) requirements.
-
Trench grates play a crucial role in effective water management, preventing waterlogging and flooding in outdoor areas. In modern hardscaping design, we believe commercial trench grates shouldn’t just serve a functional purpose. That’s why we created our decorating grating—to complement every kind of urban design and make trench grates a focal part of any project.
