Oriented Strand Board (OSB) is a type of engineered wood similar to particle board, formed by adding layers of wood strands (flakes) in a specific orientation that form a binder and then compress the wood. It was invented in 1963 by Armin Elmendorf of California. OSB may have rough and variegated surfaces, with individual strips approximately 2.5 cm by 15 cm (1.0 by 5.9 inches) placed unevenly across each other, and in various types and thicknesses.

•  Fireproofing Options – One of the biggest benefits of OSB is the option of fireproofing. Manufacturers can fire seal the wood to make it fire resistant, which is not possible with plywood.
•  Cheaper – No matter how you look at it, a piece of OSB is cheaper than a piece of plywood of the same size and thickness. In some cases, OSB is half the price of plywood. But in most cases, it’s about 20-30% cheaper.
• Thicker – OSB is naturally thicker than plywood. If you pay less for a thicker board, this may be enough to convince you to choose OSB alone.
•  Bigger sheets – OSB sheets are not only thicker, but they come in larger sheets.
• No knots – Unlike plywood, oriented strand board does not have large knots in the wood. Knots can break and leave holes in the wood, and it’s impossible to tighten them without compromising stability. So no knots are a good thing.
• Stability – OSB is often used instead of plywood and 2x6s or 2x4s joists due to the extra stability of the thickness and combination strategy. Plywood is not recommended to increase the stability of the joists.
•  Environmentally friendly – Because OSB is made from fast growing and abundant renewable trees, it is more environmentally friendly.Formaldehyde-free and chemical-free versions can also be found if you are concerned.

OSB boards all use the first-class environmental protection adhesive MDI glue, in line with the higher European environmental standards EN300 standard, the finished products also meet the E0 standard, formaldehyde emission is basically zero, compared with natural wood, fully meet the current and future needs of people for environmental protection and healthy living.

Environmental protection and safety, strict selection of high-quality pine wood, MDI glue, environmental protection and health.

Strong structure, multi-layer directional paving of board core chips, eliminates the internal stress of the board, and has no internal joints. Cracks, cracks, and overall uniformity. The upper and lower surfaces are added with middle plates, which further enhances the overall strength and supports strong support.

Impact resistance, excellent static bending strength and elastic modulus performance, impact resistance.

It is not easy to deform, the density deviation in the board is small, the moisture absorption rate is low, and it is not easy to deform.

Good nail holding power, easy processing, strong screw holding power on the board surface and board edge, durable furniture, convenient processing, meet various requirements such as sawing, sand, drilling, nails, files and so on.

As a new type of environmentally friendly building decoration material, OSB board is widely used in building structure, interior decoration and design, furniture manufacturing and other fields.

• Impact resistant – Plywood is more impact resistant than OSB. That’s why it’s often used in workshops and workbenches. It does not crack or dent under pressure like OSB, so it is also ideal for subflooring
• – Many variants – There are many more variants of plywood than OSB. That’s why it’s used in marker boards, cabinets and even airplanes.
• – Virtually waterproof – Plywood is very waterproof. It doesn’t swell much when exposed to water and is permeable, so it allows water to pass through without absorbing it. Another reason it’s used for subflooring.
• – Good curves – Plywood has much better curves than OSB. It is often used for curved projects, such as eyebrow windows. Plywood is more pliable, which makes up for its thinness and provides thickness for the purpose.
• – Solid wood – Plywood is more attractive than OSB because it looks like solid wood. This is one of the main reasons why people choose it. It has a better material appearance, whether it is present or not.
• – Longer lasting – Plywood seems to be more durable than OSB. This may be due to its water resistance unlike OSB, which absorbs and swells when exposed to water. However, the initial price may offset this.

The structure of OSB panels is more complex than that of other panels.The top and bottom layers of OSB panels are made up of a three-layer structure with the glued particle board arranged longitudinally in the direction of its fibres and the core layer of particle board arranged horizontally.

Solid wood particle board: This type of board is made from wood or other wood trimmings that are broken into pieces, glued together under heat and pressure after the application of an adhesive. OSB boards are an upgrade from particle board. Contrary to particle board, its internal structure is regular and not broken up.

The advantages and disadvantages of OSB board

Advantages.

1. High environmental performance, safe to use. The standard of environmental protection is high in the world.

2. OSB board is dried and de-oiled at high temperatures, with great strength and hardness, good stability, not easy to deformation and cracking.

3. OSB boards are novel in colour and style and can meet the personalised needs of consumers.

Disadvantages.

1. Difficult to process, due to the high hardness and density of OSB board, it is not easy to nail nails into the board when processing.

2. Expensive, as the quality of OSB board is very good, so it is also very expensive.

At present, the osong plywood on the market is uneven, the choice of osb board is a headache for everyone, how to judge the authenticity of osong plywood, and now this article hopes to help everyone.

1. Look at the surface decoration layer of oriented strand board.
   OSB has clear, natural, bright color, complete, real, strong overall feeling, soft luster and delicate hand feeling;
   It has the characteristics of anti-ultraviolet, strong color stability, long use time and no fading.
   Blurred, indistinct is the dull color of the pattern, and usually, there is a strong “shimmer” in the finish, rather than through the overall feel.
2. Look at the oriented strand board core.
   The directional board is made of fresh cold-belt coniferous material from the Alps. After cutting, skin and branches, crushing, drying, disinfection, high temperature and high pressure and other steps, strict processing procedures ensure the cleanliness and hygiene in the “aisle”. In order to make the directional board The core color is bright and white, no irritating odor, and has a natural pine fragrance.
   In the laying method, a thin-coarse-fine three-layer structure is adopted, and the boundaries between the layers are clear.
   Then, the structure of the domestic plate is adopted, and the gradient between the layers has no obvious boundaries.
3. Look at the oriented strand board sheeting.
   Look at the door panels, side trim panels, and box panels of the kitchen (or other furniture). “Oriented strand board” will not bend or deform;
   On the contrary, it may not be real particleboard.

Now People In The Choice Of Plywood Products, For Osb And Plywood Should Be How To Choose Very Headache, Now Yachen Small To Tell You How To Choose.

What Is Osb?
The Acronym OSB Stands For Oriented Strand Board. It Was Invented In The 1970s When People Started To Expand What Was Then Called Waferboard. Unlike Other Scrap Boards Such As Particleboard Or Cork, OSB Is Strategically Manufactured.
The Pieces Are Simply Placed In A Certain Way To Create A Strong New Board, But Without The Waste. It Also Uses Wood From Hardwood Trees That Grow Quickly And In Abundance. The Logs Are Cut Into Lines That Are Joined With Wax.

What Is Plywood?
Although OSB Is More Popular Than Plywood, Plywood Is Still A More Common Term And Is Often Used In Place Of OSB. Plywood Is Manufactured Differently Than OSB. Plywood Is Made From Boards Stacked On Top Of Each Other.
This Wood Is The Wood Veneer And Is Glued To Other Wood Pieces With Formaldehyde. These Layers Are Stacked In A Cross-Grain Fashion So That The Wood Will Not Split. The Better The Plywood, The More Angles Are Used.
