Hardwood strength for
demanding applications.
Hardwood Extra Line Ply overview
The supplied product description identifies this range as being made from 100% hardwood lumber, using multi-laminate hardwood veneers and a high-quality rotary Gurjan face. It is intended for applications where strength and face-veneer quality are important.
The description also states that the plywood is treated using water-soluble fixed-type preservatives under vacuum pressure to help protect against wood-destroying organisms, including insects, borers, termites and fungi.
Construction and performance
The supplied feature list mentions waterproof PF resin, double pressing, calibrated thickness, a pre-jointed wider core and panel, and high nail-holding capacity.
The product material supplied for this page identifies IS:710 criteria and provides the technical values shown in the table below. Values are transcribed from that supplied table.
