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 trench grates have redefined the role of gratings and drain covers in the architecture industry. With Jonite 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.

All products in Jonite trench grates collection are available in exquisite textures and colours. All its trench grates give you the finish of natural stone with the strength to sustain pedestrian and vehicular load performance and durability for a lifetime.

Jonite absorbs much less heat compared to traditional ferrous gratings, making it a more comfortable material to have around the house and in children’s playgrounds. Also, it has dielectric properties equivalent to porcelain, making it an excellent electrical insulator- a significant plus point in times of tropical thunderstorms.

Landscape architects like yourself have used our trench grates for a variety of purposes, such as outdoor drain covers, trench grating along driveways, storm drainage and indoor applications. Aesthetics and functionality in a perfect marriage culminating in Jonite products makes us the natural choice.
