STRUCTURAL PLYWOOD OR MARINE PLYWOOD IN SOUTH AFRICA
In the Pacific IslandsMarine Plywood Marine Plywood Marine Plywood is often specified by building designers. Structural Plywood is specifically designed for bui Structural Plywood lding purposes whereas marine is made for use in boat building.
Structural Plywood made in New Zealand (such as Ecoply) is subject to stringent third party quality control audits by the Plywood Association of Australia (PAA).diy putting hand rail on porch steps Product compliance and performance in building (strength, stiffness and durability), is linked through the manufacturing standard. (AS/NZ 2269) to the design standards. (NZS 3603 and AS 1720) and into the Building Code.
No standard of Marine Plywood (e.g. AS/NZS2272:2006) is linked to the New Zealand building code however perceived durability appears to be the main reason architectural designers ask for marine. Consider both the adhesive and the wood.
The Adhesive The Adhesive
The glue bond in Structural Plywood to AS/NZS 2269 is the same as that used in high quality marine plywood. The adhesive is phenol formaldehyde (PF) resin that is cured at high temperature and pressure to give a brown coloured glue line with proven exterior performance of over 50 years. Once set, the bond cannot be reversed and will not release free formaldehyde.
Structural plywood therefore has the same so called marine bond.[url=http://compositedeckingfloor.com/news/8812.html]american made wpc decking[/url] In AS/NZS 2269 This is called the Type A phenolic bond. Hence the glue lines in properly made Marine and Structural plywood have the same durability.
The Wood The Wood
Marine plywood is made from essentially clear veneers throughout the whole plywood sheet to enhance water proofing and performance under localized water pressure. This makes it very expensive, because clear wood is more expensive than knotty wood.
Structural plywood is generally made with a specified A, B, C or D grade face veneers. The other non-visible plies are C or D grade veneer with knots or holes.balcony steps outside A and B grade faces are essentially clear , C grade is a filled face with small knots, and D has natural knots and open defects up to a maximum limit.
