Frequently Asked Questions
Can these three-layer HDPE sheets be used outdoors all year round?
Yes. The sheets are manufactured from UV-stabilised HDPE and are designed for continuous outdoor use. They resist moisture, sunlight and general weathering, making them suitable for signage and panels exposed to the elements throughout the year.
How are the contrasting colours revealed for text and graphics?
The sheet is made with a coloured core sandwiched between two outer layers of a different colour. When you engrave, rout or machine through the top surface, the inner core colour is exposed, creating sharp, high-contrast text and graphics without the need for painting or printing.
What tools and methods are recommended for cutting and machining these sheets?
These HDPE sheets can be processed using standard woodworking or plastic-working tools. Common methods include routing, CNC machining, sawing with fine-toothed blades, drilling and engraving. Ensure tools are sharp and speeds are appropriately set to achieve clean edges and precise detail.
