Co-Extruded WPC / FRP / Steel Profiles

SIS has used our standard WPC and FRP range to develop ground breaking technology.  We are combining two different materials, WPC and either steel or FRP, to co-extrude a market leading multi-composite material that is manufactured in a continuous length manufacturing process. This has either a steel or FRP hollow core of any shape and an outer layer of WPC. If choosing FRP, the hollow core can also be filled with foaming agents of different density as per customer demand to for various compressive strength outcomes or reasons including vermin abatement. Although the FRP core is more expensive, it offers the stakeholder a WPC product with world leading strength and durability… When considering products such as decking, this new technology allows for clear spans never achieved before with a WPC product. With an outer WPC layer, it also removes the need for FRP to be painted for additional UV resistance in harsh conditions.
