Classic Collection
Clean lines, superior load strength, and an entire range of sizing options to choose from—there’s a reason these engineered stone trench grates have been with us since the beginning.
Our Classic Collection features some of our best-selling trench grate covers. Fit for everything from pedestrian areas to robust fire engine zones, you can choose from our standard selection of colours and textures—or, personalise your space further with a custom trench grate design.
Composition
<1% crystalline silica
Our composite mix replaces substances like quartz with safer raw materials. All our engineered stone trench grates now feature less than 1% silica and are approved for use in Australia.
95% natural aggregates
All our trench grate covers are crafted using at least 95% natural aggregates and just 5% hybrid polymers. The result: a more sustainable product—and a more natural-looking, long-lasting finish.
30% recycled materials
Every Jonite trench grate cover is made using at least 30% recycled materials. Any surplus stone and steel that doesn’t meet our strict manufacturing standards is reused as raw materials in future projects.
Reinforced with steel frames
Reinforcing our stone grating with treated steel frames makes them just as strong as cast iron alternatives. And by using 80% less steel in our manufacturing, we’ve lowered our carbon footprint by 16x.
Specifications
High-performance decorative grating. Designed with safety, durability and versatility in mind.
Approved worldwide
All the materials in our grating products meet the latest global safety standards. This includes the new legislation that applies to products containing crystalline silica.
Made to last
Made from natural materials chosen for their load-bearing qualities, our decorative grating is built to withstand high levels of traffic, whether it be pedestrians or HGVs.
Low heat absorbency
Jonite trench grate covers absorb less heat than traditional metal and cast iron gratings, making them safe for indoor areas and children’s playgrounds.
Non-slip surface
The naturally matte, slip-resistant surface of our commercial trench grates meets the international safety classifications required for schools and hospitals.
Rust + corrosion proof
The rust-resistant, anti-fade properties that come with engineered stonework mean our decorative trench drain covers are designed to last—both indoors and out.
A-rated electrical insulation
Our engineered stone outdoor drain grates have the same dielectric properties as porcelain, so are ideal for towns and cities prone to tropical thunderstorms.

Burj Khalifa, Dubai
Read moreSoaring to a height of over 2,700 feet, the Burj Khalifa stands as the defining landmark of Downtown Dubai and a global symbol of architectural ambition. As the tallest skyscraper in the world, it anchors a vibrant urban district filled with luxury residences, world-class retail, and cultural attractions. Seamlessly integrated into the fabric of the city, the tower offers direct access to The Dubai Mall, the Dubai Opera, and the scenic Burj Park, while its commanding views stretch across the Arabian Gulf and the desert beyond. The Burj Khalifa is more than an engineering marvel—it represents the bold, future-facing spirit of Dubai itself.

Tarrawarra Musuem of Art, Australia
Read moreSet against the rolling hills of Victoria’s Yarra Valley, the TarraWarra Museum of Art: Eva and Marc Besen Centre is a refined addition to one of Australia’s leading cultural destinations. Designed by Oculus, the centre expands the museum’s presence with a carefully integrated landscape and architectural response that honours both the natural beauty and artistic legacy of the site.
