Enviroplate Substrate

A greener, more durable road sign substrate.

Road Sign made with Enviroplate

Reduce the Cost of Your Streetwork Signs by Switching to a More Durable Substrate

We developed Enviroplate Substrate as a greener alternative for our Quick-Lock Post System and Temporary Signs. And it’s so good, we believe it makes some sign substrates obsolete. Because not only is it more durable and unlikely to break or bend out of shape. Which means signs last longer and are able to withstand deployment & on-site conditions. But it’s also made from 100% recycled materials that can be reclaimed and reused. So it lowers your costs and environmental impact too.


Resistant to Bending, Breaking & Corrosion.


Has Clean Edges when Cut, Drilled or Engraved.


A 100% Recycled Substrate that’s Recyclable.


Significantly Lowering its Carbon Footprint.

Make & Deploy Signs That Last

Enviroplate is our answer to temporary signs biggest problem, the substrate. Whatever you use, it struggles to cope with regular transport & on-site handling. Since it’s more durable than GRPolyplate and Composite, Enviroplate wont bend & damage your sign faces. And it’s resistant to standard impacts, chemicals and weathering. So your signs remain legible and effective for much longer too.

As a result of its dense structure, it’s highly resistant to the elements & will not breakdown and crumble. This also means it produces clean edges when cut, drilled and engraved. So you wont need to use brass eyelets for Quick-Fit toggle points.

Highways Safety Devices

As a Polypropylene Copolymer (PPC), Enviroplate is softer than general purpose homopolymers. But with better impact, higher stress and low temperature resistances. Moreover, polypropylene’s offer a combination of outstanding physical, mechanical, thermal, and electrical properties.

These traits also make it ideal for Highways Safety products like our Quick-Lock Posts & Cone Reflectors. Sheets can be laser-cut and routed, or thermally heated and folded to make products. And it’s compatible with Oralite Reflective films, used for common safety devices.
