INFORMATION FOR REFERENCE:
We'd like to share a wide range of information on OSB (Oriented Strand Board) regarding the properties of OSB, how is OSB made, what is made from, why could it better than the alternatives etc...

OSB-2
OSB/2 -a cost-effective and versatile panel,ideal for non-structural applications such as boarding-up,packaging,signboards and furniture etc.
0SB/2 is used mostly in dry conditions whilst OSB/3 is used in more humid conditions. It is also available in tongued and gooved boards,Bitumen coated boards for roofing applications, Flooring OSB with a peel off protective film.
OSB/2 is used in the folwong areas, boarding up,packaging,flooring,furniture,pallet tops,signboards and temporary formwork.

OSB-3
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.
It's made for exterior sheathing, outdoor use only ,and no harm to the human and the environment.
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.
OSB/3 is used for roof decking, roof sarking,wall sheathing,flooring,packaging,hoardings,signboards and portable buildings.

What is OSB?
OSB also called waferboard,Sterling board, is the short name for Oriented Strand Board,it's made by small piece wood veneer(flakes) 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...

Why choose OSB instead of plywood ?
Our Consmos OSB panel won’t cup, warp, split or delaminate as easily as plywood. You can count on consistent quality, without core voids and knots. Our OSB sheathing is uniform, strong, dense, consistent, defective free, and easy to work with. And our OSB is environmentally friendly, using wood from small, fast growing trees locally or from the wasted veneer small pieces since here in Linyi there are hundreds of plywood factories which provide us the surficient small veneers. That means less waste and better use of wood resources.
