Architects, developers and other customers of hardscape design make Jonite their top choice when choosing eco-friendly grates for a landscape. We’re proud to hold a Leadership in Energy and Environmental Design (LEED®) certification for our global efforts to use materials responsibly. In our manufacturing process, we incorporate at least 30% recycled content in our products, including our tree grates. This process is our commitment to contributing to a healthier, more sustainable environment.

Our stone composite products consist of 95% natural aggregates and advanced natural polymers. The use of welded materials provides high performance and reliable, load-bearing strength for standards applications in zones with pedestrians and vehicles. We comply with BS EN 124:2015 and 1433:2008 directives, making our grates an excellent option for trees needing drainage solutions in any residential or commercial area.

Our company’s journey started with a dream to create the first grate made of stone with the long-term strength and durability to match one of metal. We wanted to provide the same aesthetically pleasing visuals as the stone castles created in the Middle Ages. After seven years of extensive research and development, we launched the world’s first reinforced stone grate for commercial use in 1994.

Our company encourages you to get creative with customized designs. You can bring any idea to life with artistic or contemporary patterns made with our stone composite.

Benefits of Custom Jonite Tree Grates

Trees are essential in landscape planning. They have positive effects, such as reducing urban warming effects, providing shade to pedestrians, and adding a focal point to your driveway. Suitable for any tree, the features of our grates offer the following advantages:

  • Pedestrian safety: Tree grates are vital because they help avoid soil compaction for proper drainage and prevent tree roots from becoming obstacles to pedestrians, thus creating more walking space. The rough and natural matte textures of our grates meet international slip-resistance guidelines, providing safety near hospitals and schools.
  • Nature accommodation: Our tree gratings are designed with the promotion of tree protection in mind, allowing rainwater to seep through while having narrow slits to prevent litter from falling through and smothering the soil. Some of our tree grates allow for the expandability of inner diameter to accommodate the exponential growth of tree trunks during the maturity stage. Add inner rings when the trees are younger and remove them as the tree matures.
  • Theft prevention: Cast-iron tree grates may be prone to theft. Jonite-reinforced stone tree grilles are theft-resistant because they do not pose any value for scrap due to their stone material integrity.
  • Temperature control: Jonite tree grates have low heat absorption properties to help create a conducive environment for the trees. Using cast iron or metal can cause surrounding temperatures to soar, which might not promote ideal growth in trees.
  • Americans with Disabilities Act (ADA) compliant: Some of the Jonite tree gratings are certified ADA compliant. Making our tree grates accessible in hospitals, clinics, and public areas as wheelchair users have no issues navigating their way around the grills.

Are Jonite’s tree grates compliant with the American Disabilities Act (ADA)?

Selected models are ADA compliant. However, Jonite can modify and customize any of your preferred designs to accommodate the ADA guidelines.

Do Jonite tree grates come with inner ring expandability for my growing trees?

Not all tree species need this feature, but if you do, we have selected models like our ADA Collection, which offers up to 4 different inner diameters (390/460/530/600mm). Should you need even more expandability, some models like the Square Slots can expand even beyond that. Feel free to contact us for further advice.

What kind of customizations are we able to do on Jonite tree grates?

Apart from the usual color and design customizations we offer for most Jonite products, we also provide custom configurations for our tree grates. For example, if you require tree grates for a large area or in a unique shape, we can customize their configurations to fit your needs. We can also customize its expandability, lockability, and light ports as well.

Do I need a minimum order quantity to customize tree grates?

Not at all. We are happy to customize just one set of tree grates for you.

Are Jonite tree grates suitable for the vehicular application?

Our standard models can only sustain loads of up to 5KN which is strictly for pedestrian application. However, feel free to contact us for custom tree grate designs and support frames for specific Load Classes. Please note that tree grate supports need to be certified by a professional engineer to sustain their Load Class.

How durable are Jonite tree grates compared to cast iron tree grates?

Compared to cast iron tree grates, Jonite tree grates do not rust with time and are extremely durable. By using a proprietary stone composite material that ages similarly to natural stone, they are also UV and weather resistant.

Are Jonite tree grates slip resistant?

Jonite tree grates are slip resistant. We have conducted Pendulum and Ramp tests on our products 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, Jonite can handle most locations and applications.

Are Jonite’s products sustainable?

Jonite commits to environmentally sustainable practices. We actively manage our energy, water, and waste with the future in mind. We use at least 30% recycled aggregates, which reduces carbon emissions by up to 80%.

Jonite products are also Singapore Green Building Product (SGBP) certified (4 ticks, leader).
