Plyform HDO Plywood Concrete Form panels

The mills manufacture concrete form or high density overlay (HDO) plywood with a resin fiber surface.  The factory impregnates the fiber surface with a thermosetting resin and then bonds the resin fiber surface to both sides of the board with heat and pressure.  The mills construct HDO plywood with 100 percent moisture resistant glue with interply construction of C or C-plugged veneer. Face veneers are B-grade.

HDO is rugged and is ideal for such punishing applications as concrete forming and industrial tanks. The tough resin overlay withstands severe exposure without further finishing. It also resists abrasion, moisture penetration and deterioration from many common chemicals and solvents.

HDO is a very versatile product. The rail and trucking industries use the product to line vans and rail cars. HDO’s agriculture uses include fertilizer bins, structural walls both interior and exterior where an easy to clean, abrasion resistant surface is desirable. HDO also works well in many marine applications such as bulkheads, transoms, hulls and hatch covers.
