Products | Plywood Bridge Decking

Plywood large section bridge decking was first developed by Hancock Bros as a replacement for timber “rattle” boards on Australia’s traditional timber bridges. It entered the market in the mid 1980’s as a CCA envelope treated panel taking many years to gain market acceptance.

With advances in preservation treating, in particular veneer treating, and bonding technology the product has evolved into a flexible light weight robust bridge deck panelling system suitable for road and rail applications a like.

NiuDeck is a purpose designed and engineered heavy plywood decking system which is primarily used for re-decking traditional timber bridges. NiuDeck is manufactured from sustainable plantation pine with H4 veneer treatment preservation with 100% penetration. In addition, a custom design service is available to manage the most challenging applications.

NiuDeck can be used with steel or timber supporting structures including wharf and rail deck applications.
