Arbec Forest Products Inc. is a company specialized in the production of OSB panels. In Quebec, New Brunswick and elsewhere in Northeastern America, we do business with entrepreneurs, wholesalers, manufacturers and buyer groups who know they can count on our seasoned know-how and effective integration of the latest technological innovations.
An oriented strand board (OSB) is a structural panel composed of thin wood strands chipped from aspen logs. Since they are cut in the direction of the fiber, the strands retain the strength of the wood, making a resistant material.
After harvesting, the logs are transported to the factory wood yard where they are sorted according to species.
The logs are immersed in conditioning ponds for cleaning and thawing, to prepare for processing.
The logs then pass through a debarker, where the bark is stripped off. The bark will be used as fuel for the plant's energy production.
The logs are then sliced into thin strands (wafers) of a specific size.
The strands are stored in wet bins until ready to be dried.
The strands pass through a rotary dryer until the desired humidity is reached. Fine particles are sieved off, for use as an energy source.
The strands are then mixed with resin and a small amount of wax, which improves the efficiency of the resin and increases resistance to moisture and water absorption.
The strands pass through orienters which form a mat composed of individual layers superimposed perpendicularly to each another.
The mats are pressed at high pressure and high temperature which causes the resins to react, thus forming a high density structural panel.
The panels are cut into standard sizes (4 'x 8'), and stamped according to grade. Once stacked in bundles, a sealant is applied to the sides to increase water resistance.
Bundles are stored for a minimum of 48hrs. This is in order to complete the curing of the resin, and let the internal heat evacuate.
Finally, the panels are ready to be loaded and shipped to their final destination. Transportation is usually by truck, but can also be by train, or by boat.
