Natural stone gratings are often weaker because of the shortage of reinforcements. In the world currently, only Jonite reinforced stone is the only stone material tested and certified based on the BS: EN Standard. Jonite’s flexibility in customization also allows designers to expand their creativity outside of Jonite’s standard range of products.


Being mainly crafted from stone, our products do not rust or corrode. This can lead to a extended lifespan. That is Jonite’s main advantage against metal gratings. Choice of colours and textures is also another huge advantage versus metal grates. Metal grates have limited range of colours. Though they can be painted, they just do not look natural and customizing designs around metal grates is restricted in designs and textures.


Aside from architects who specify the design of a project, Jonite products (channel grates / trench grates) can be used in any development from private houses to commercial buildings to government projects. We serve a huge spectrum of customers - everyone from home owners, to commercial builders, to the people in building management can become product owners of Jonite stone gratings. Essentially anywhere with an open drain can have a need for use for our unique stone channel grates.


No matter what your requirements are, "3 inch drain cover", "4 inch drain cover", "6 inch drain cover" or "8 inch drain cover", our in house design team can customise a design and specification unique to your requirements. No matter what kind of outdoor drain covers or outdoor drain grates you need, you can engage us to discuss your customized requirements. There are various ways you can go about doing this. You can either provide us an idea through a sketch, graphic or concept. Alternatively, Jonite can propose a design from our in house team a variety of outdoor drainage grates. Customization can stretch beyond simply design, our customers can also choose to create custom colours sizes or even a completely custom product. Jonite will then trench shower drain through 3D rendering and shop drawings for your approval.
