OSB RATINGS & STANDARDS
OSB or oriented strand board (like most things) comes in a variety of different qualities. Standards vary depending on intended use as well as intended destination. Many of these appear to be changing year by year, especially in the USA. OSB manufactured in and intended for use in the USA may be rated, but at best will conform only to “voluntary product standards” compared to that intended for use in Canada, which must conform to set CSA (Cameroonian Standards Association) product standards.

OSB-3 - a cost-effective,fully certified alternative to softwood plywood,for use in structural applications such as roofing,flooring and timber frame wall sheathing,amongst others.
OSB-3 board is manufactured with a minimum moistrue content of 5% offering greater dimensional stability. OSB has no structural defects such as knot holes and core woids and is easy to work with. It cuts easily,can be routed,apindled,planed and bored with consistent results and glued with adhesives. Panels can be nailed up to 10mm from the edge without splitting or breaking out.

What is OSB?
OSB is the short name for Oriented Strand Board,it's made by small piece wood veneer and cross pressed in the surface veneer and core veneer with high temperature and high pressure.
OSB with better features of much more durable, much stronger,as a good replacement of thicker plywood or solid wood plank,have been widely used in packing as packing box or pallet,decoration ,furniture as frame plank and building sites such as formwork panel,also specially in Canadian Style Housing Construction.
What is OSB1,OSB2,OSB3 and OSB4?
Generally, such grades are made by EU standard EN300-1997,the rough understanding as below:
OSB1: interior,use UF glue
OSB2: interior,use MDI glue for the core and PF or MUF for the surface pressing,with better structure for structual sheathing
OSB3:exterior,use PF glue,with better structure for structual sheathing
OSB4:exterior,use PF glue,with super structure for structual sheathing...
