China Plain OSB Board OSB Packing Poplar Veneer OSB, Find details about China OSB Board, OSB Panel from Plain OSB Board OSB Packing Poplar Veneer OSB
From squeak-free floors to solid wall and roof sheathing, oriented strand board (OSB) is shaping how the world builds. OSB is engineered for strength and designed for a variety of
applications. OSB is a proven performer for many residential and nonresidential applications.
Its high performance capabilities make OSB ideal for diverse markets, including materials-handling applications, the structural insulated panel industry, do-it-yourself projects, wood I-joist products, and industrial applications such as furniture and trailer liners.
OSB is made from real wood
OSB is manufactured in a cross-oriented pattern similar to plywood to create a strong, stiff structural panel. OSB is composed of thin rectangular-shaped wood strands arranged in layers at right angles to one another, which are laid up into mats that form a panel. OSB is bonded with water-resistant adhesives. Most panels are also treated with a sealant on the panel edges to guard against moisture penetration during shipment.
As an added feature, panels are often textured on at least one side to provide a slip resistant surface. OSB uses the wood resource very efficiently, in part because sheathing panels can be made using smaller, younger fast-growing tree species, such as aspen and southern yellow pine. Plus, about 85-90 percent of a log can be used to make high quality structural panels, and the remainder--bark, saw trim, and sawdust--can be converted into energy, pulp chips or bark dust.
OSB manufacture
In the first phase of OSB manufacture, logs are debarked and cut to a uniform length. The logs are then turned into strands. The strands are dried with heat in a large rotating drum which is screened to grade for strands that are the correct size.
Liquid or powder adhesive is applied to the dried strands and then transported in layers on a conveyer system to a forming line, where the layers are cross-oriented into mats. Face layer strands generally run along the panel, while core layer strands are randomly oriented or run across the panel.
The mats are trimmed to a workable size and then moved to a press where the wood strands and adhesive are bonded together under heat and pressure to create a structural panel.
Finally, the panels are cut to size. Panels can be manufactured in many sizes simply by altering the cutting pattern.
OSB is engineered to perform
Nearly four decades of laboratory tests and use in the field have proven that OSB is an excellent performer. Performance begins when the panel leaves the manufacturer. The panels remain flat and square during storage and transportation, so they arrive at the jobsite flat and easy to install; tongue-and-groove panels effortlessly fit together. Relative to their strength, OSB panels are light in weight and easy to handle and install. Frequently, the panels are textured or splatter-coated on one side to increase traction on the panel surface. This is especially useful when the panels are used for roof sheathing, because
the textured surface provides better footing for workers. OSB is designed to withstand exposure to the weather during construction.
OSB's performance continues long after the panel is put to use. The panels exhibit excellent fastener-holding capability, even when nailed close to the panel edge. OSB resists deflection, delamination and warping because the wood and adhesives work together to create a strong, dimensionally stable panel. OSB panels are made of real wood, a natural insulator which provides excellent protection against heat loss and condensation. Many OSB panels are manufactured in large dimensions, minimizing the number of joints that can 4°leak4± heat and admit airborne noise into the structure. In addition, the panels resist racking and shape distortion under high wind and earthquake forces.

OSB for sheathing
OSB Sheathing is intended for subflooring, wall sheathing, and roof sheathing. APA Rated Sheathing/Ceiling Deck can also be made using OSB; it is made so that one surface has an overlay, texturing, or grooving.Common thicknesses for sheathing panels are: 3/8 inch
(9.5 mm), 7/16 inch (11.1 mm), 15/32 inch (11.9 mm), 1/2
inch (12.7 mm), 19/32 inch (15.1 mm), 5/8 inch (15.9 mm),
23/32 inch (18.2 mm), and 3/4 inch (19.0 mm).
OSB for flooring
OSB Sturd-I-Floor is intended for single-layer flooring under carpet and pad. Sturd-I-Floor
panels often have tongue-and-groove edges.Common thicknesses for flooring panels are: 19/32 inch (15.1 mm), 5/8 inch (15.9 mm), 23/32 inch (18.2 mm), 3/4 inch (19.0 mm), 7/8 inch (22.2 mm), 1 inch (25.4 mm), and 1-1/8 inches (28.6 mm).
OSB for industrial and do-it-yourself applications
OSB is also widely used in industrial applications. It can be used for mezzanine floors and shelving in commercial and industrial structures. OSB also is used in furniture, reels, trailer liners, recreational vehicle floors, roofs and components.
OSB STORAGE AND HANDLING
As with plywood, OSB panels require proper storage and handling. Always protect ends and edges, especially tongue-and-groove products, from physical damage. When moving bundles of panels with a forklift, place the bundles on pallets or lumber bunks to avoid damaging them with fork tines. When transporting panels on open truck beds, cover
the bundles with a tarp.
Whenever possible, store the panels under a cover. Keep sanded or other appearance-grade panels away from high traffic areas. If moisture absorption is expected, cut the steel band on the bundles to prevent damage.
When storing panels outside, stack them on a level surface on top of stringers or other blocking. Use at least three stringers. Never leave panels in contact with the ground. Cover the stack with plastic or a tarp. Make sure the bundle is well ventilated to prevent mildew.
