high density polyurethane
The high density polyurethane (HDP) provides many benefits such as: 

Excellent light weight alternative to GFRG, GFRC, FRP, and even traditional wood products.

Polyurethane products offer ease of installation using common woodworking tools and equipment which in turn save labour costs and machinery rentals.

Polyurethane has a closed cell structure which provides protection from moisture and therefore will not rot. Further, the closed cell structure prevents paint from peeling from the surface.

HDP products provide no nutritional value and as such also resist the growth of mildew and fungus.

Polyurethane will not crack or warp when properly installed using installation instructions as detailed in the catalog.

They are not affected by ultraviolet rays when properly coated.

As you can see,polyurethane offers versatility, durability and value for any project
