What does PSL mean in construction?

Parallel Strand Lumber (PSL)

What does PSL stand for in construction?

Parallel strand lumber (PSL)

What is the difference between a PSL and LVL beam?

PSL beams are generally more expensive than glulam, LSL, or LVL beams. PSL beams can be stained or finished where an aesthetically pleasing exposed application is desired. Laminated Veneer Lumber (LVL) is a commonly available engineered product that is manufactured similarly to PSL.

What is stronger LVL or PSL?

Laminated Veneer Lumber (LVL)

LVL leverages heat and pressure to bind thinly sliced veneers parallel to one another, a process that is particularly accommodating to narrow beam dimensions. Its shear strength is superior to LSL but doesn't quite match PSL's ability to withstand bending stress.

Can you rip a PSL beam?

No, Parallam® Plus PSL must maintain its original cross section and shall not be re-sawn in depth or thickness.

PSL Construction - What We Do

How far can a PSL beam span?

* The span and load tables in this guide cover beam spans up to 60 feet; however, 2.2E Parallam® PSL beams can be delivered in lengths up to 66 feet.

Are PSL posts pressure treated?

Parallam® PSL products enter an airtight treatment cylinder—a highly controlled, pressurized environment where they are exposed to the Wolman® treatment process.

What is PSL beam?

Parallel-strand lumber (PSL) is a form of engineered wood made from parallel wood strands bonded together with adhesive. It is used for beams, headers, columns, and posts, among other uses.

What is the strongest engineered wood beam?

Power Beam® is the strongest engineered wood product (EWP) on the market with design values of 3000Fb - 2.1E - 300Fv. Power Beam® is manufactured with superior strength southern yellow pine MSR Lumber.

Can you drill a hole in an LVL beam?

Whenever possible, avoid drilling vertical holes through LVL beams unless the beam width is at least 3-1/2 inches. Prior to drilling any vertical holes, an engineer or architect qualified in wood design should be consulted.

Which is stronger LVL or glulam?

The laminated beam is stronger but more expensive and used when bigger cross-sections are required. Generally made from hardwood, rather than the lvl softwood. Better performance from a laminated beam can be got when using cambered lamination.

How much stronger is LVL than lumber?

Laminated veneer lumber (LVL) studs can be two times stronger in compression and tension than standard framing lumber of the same dimension.

Can you sand and stain an LVL beam?

NelsonPine LVL billets in standard thicknesses come with an industrial type finish that can have normal timber paint and stain systems satisfactorily applied to them. Enhancement of the visual appearance and coating adhesion can be achieved by relatively coarse sanding the surface prior to the first coat.

What does PSL mean on my bank statement?

PSL stands for Priority Sector Lending (finance)

What size lumber can span 20 feet?

For a 20 foot span, you will need atleast 2×12 size of lumber/ floor joist when spaced at 16″ apart. Thus, a 2×12 size of lumber can allow to span 20 feet. For a 20-foot spans, the lumber has to be at least 12 inches in depth used as floor joist.

How much weight can an engineered beam hold?

Note: a single 2×6 will support 347 pounds per lineal foot of beam. Therefore, a double 2×6 carries 2 x 347 = 694 pounds per lineal foot.

What size lumber can span 16 feet?

For a 16 foot span, you will need atleast 3-2×14 or 6×14 size of wood beam. Thus, a 3 nailed 2×14 or 3-2×14 or 6×14 wood beam can allow to span 16 feet. For a 16-foot spans, the wood beam has to be at least 14 inches in depth and 6″ in width (3-2×14) used for residential building, wood frame structure or projects.

What does PSL mean in wood?

Parallel-Strand Lumber (PSL) is one of the types of engineered or manufactured wood that was developed in the late 20th century. PSLs are usually used in wood-framed construction for girders to support smaller beams of laminated veneer lumber (LVL), wood trusses, or wood I-beams.

Can PSL be painted?

See specifier's guide for Parallam® Plus PSL Beams, Headers and Columns, TJ-7102, for additional information. Can Eastern Parallam® PSL be stained, painted or finished? Yes. As with any Parallam® PSL product, Weyerhaeuser recommends sanding the surface prior to apply painting or staining.

Can PSL be fire treated?

It is important to note that designers must always verify compliance of this approach with the authority having jurisdiction, especially for applications that require fire retardant treatment in the code. This is because Parallam PSL cannot be treated with fire retardant.

What is a Wolmanized PSL?

Weyerhaeuser Trus Joist® Parallam® Plus PSL products, with Wolmanized® preservative protection, are treated with copper azole (beams) or CCA (columns). These preservatives are U.S. EPA-registered pesticides that are used to protect against insect (termite) attack and fungal decay.

How big of a beam do I need to span 20 feet?

For a 20-foot spans, the wood beam has to be at least 16 inches in depth and 8″ in width (4-2×16) used for residential building or projects.

Is glulam stronger than steel?

Glued laminated timber, or glulam, is a highly innovative construction material. Pound for pound, glulam is stronger than steel and has greater strength and stiffness than comparably sized dimensional lumber.

How much does an LVL cost?

LVL beams cost on average $3 to $12 per linear foot for the material or $50 to $200 per foot installed. LVL beams are more cost-effective and durable than regular wood beams. LVL beams are fire-resistant, shrink-proof, and easy to install, especially in long spans.
