Tree Gratings Specifications

Trees are essential in landscape planning. They are having positive effects such as reducing urban warming effects, providing shade to pedestrians, and adding a focal point to your driveway.

Tree grates are vital because they help avoid soil compaction and prevent tree roots from becoming obstacles to pedestrians, thus creating more walking space. 

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 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 as the tree matures.

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. 

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.

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.

Our tree grille designs allow for fully customizable light ports or sockets for the installation of many different types of lighting for night illumination. We are adding an exciting dimension to the natural beauty of trees. Efficiently emboss a corporate insignia or municipal logo right onto the tree grates in your environment, giving an exclusive identity to the locale. 

We also incorporate the use of at least 30% recycled content in our products, including our tree grates. This process is our commitment to contributing to a sustainable and green environment.

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 reinforced stone, which reduces carbon emissions by up to 80%.

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