EGGER OSB HDX is a heavy duty, load bearing OSB4 panel suitable for use in humid environments. It has a tongue and groove profile on the 2 long edges.It is an idea solution for heavy duty load bearing environments such as mezzanine flooring, racking, shelving, working platforms and decking, where P5 or P6 38mm particleboard would typically be used. It is laid the same way as 38mm particleboard. However, due to being only 30mm thick, EGGER OSB HDX is around 20% lighter, making it easier to manoeuvre and quicker to lay.
