Parallam psl

Create long, clear spans and support heavy loads, whether inside or out in the elements. You’ll see the difference from the start—thanks to our new and innovative proprietary sealant. These billets are then cut into specified beam and column sizes. Parallel-strand lumber ( PSL ) is a form of engineered wood made from parallel wood strands bonded together with adhesive.

Our manufacturing process uses veneer strands, allowing a significant percentage of each log to become a high-grade structural member. They are made using long thin strands of wood and a super strong adhesive glue to give you perfectly predictable beams and columns. Column members can even be used in saltwater splash applications. Beam Modifications.

Using a patented process to bond together long, thin strands of woo Parallam unites strength and consistent performance to create support members that deliver over the long haul. Parallam PSL has been engineered to support heavy loads and span long distances. MacMillan Bloedel invented and commercialized PSL under the brand name parallam. This company is now present under the name of Weyerhaeuser. It is the only commercially manufacturer of PSL products.

Ideal for cantilevers and tall wall designs. PSL manufacturing involves little waste, as almost all parts of a log are used in the product. The ideal solution for super strong, stable decks, porches and balconies. Under the Parallam trademark, TJ markets its parallel strand lumber ( PSL ) products. Other products are available by special order.

Below are the engineered lumber items that we keep in stock. We also stock an extensive line of engineered hangers from USP and Simpson, the two major brands in the business. Le ParallamMD PSL permet des portées plus longues sans poteaux ou colonnes intermédiaires pour les plans à aire ouverte.

L’aspect unique de son fil en fait un matériau idéal pour des applications de poutres apparentes. Parallel strand lumber ( PSL ) describes long strands of engineered lumber that is formed together to create durability and strength. Because it supports heavy loads, it is used for beams, columns, headers and much more.

For use as a structural building column, Weyerhauser has simplified product design and specification by grouping the AWPA (American Wood Preservers Association) Use Categories into Service Levels. Parallam, manufactured by Trus Joist MacMillan (TJM), virtually defines the terparallel strand lumber (PSL). PSL is an assembly of long, thin strands of wood veneer glued together to form continuous lengths of beam. The wood fiber used is strong and stiff. Several widths from ¾” – 7″ are available in depths of ¼” – 18″.

The manufacturing process of OSL enables large members to be made from relatively small trees, providing efficient utilization of forest resources. Parallel Strand Lumber ( PSL ) Parallel Strand Lumber ( PSL ) provides attributes such as high strength, high stiffness and dimensional stability. In Canada, PSL is fabricated using Douglas fir.

What are the relative merits of the three beam types that they offer LSL(Timberstrand), LVL(Microlam) and PSL ( Parallam ). I have a few questions…. Builders use these materials to create durable, high-quality structural frames for demanding applications, while helping avoid costly callbacks from warped lumber, nail pops, wall cracks and other framing problems that arise after installation. We Carry Engineered Lumber Products From Names You Can Trust! Posts are embedded in the ground to a depth of roughly half the exposed height of the barrier and backfilled with crushed stone or concrete.

PSL beams are primarily used in beam and header applications where high strength is required.
