manufacturers of engineered wood products: Structural Panels: Plywood and Oriented Strand Board (OSB) prefabricated wood I-joists shall be established and APA Product Reports • Report indicates that product meets the intention of the listed codes when used as stated and within the specified limitations. This econometric study covers the world outlook for engineered structural wood I-joists and I-beams across more than countries. For each year reported, estimates are given for the latent demand, or potential industry earnings (P.I.E.), for the country in question (in millions of U.S. dollars), the percent share the country is of the region and of the globe.
An engineered wood beam is a wood product or assembly designed to replace traditional structural lumber. The engineered product is stronger and allows for greater spans. Sizing engineered wood beams is not at all difficult. The easiest way to size engineered wood beams is to use the span tables that the manufacturer provides. [Show full abstract] included one floor framed with No. 1 Southern yellow pine floor joists, which served as a control, and two floors constructed with wood I-joists. All floors were sheathed with.
Advantages of I-joists - 1. Readily available and relatively cheap. 2. Long spans are readily available - We sell up to 48' 3. Cut to fit in the field. Disadvantages of I-joists - 1. fire performanceAdvantages of floor trusses - 1. Lots of room for mechanicals (Particularly in deeper depths) 2. . Because of the predictable spanning and load-bearing capabilities of engineered wood beams, builders, designers, architects, and engineers have made them a common framing component in buildings with wide open spaces and big daylight openings.

Geometry, Stress and Strain. Imagine what happens to a joist as you add weight to the floor. Intuition and experience tells you. Making the Best Use of Resources SCL Basics. Structural composite lumber (SCL), which includes laminated veneer lumber (LVL), parallel strand lumber (PSL), laminated strand lumber (LSL) and oriented strand lumber (OSL), is a family of engineered wood products created by layering dried and graded wood veneers, strands or flakes with moisture resistant adhesive into blocks of material known as.

A popular construction material these days are floor I-beams, sometimes called "Engineered Floor Joists." You have seen them. They are convenient and easy to use. But there are strict guidelines for notching or cutting holes in engineered floor joists.
From the side they look like a. Structural Wood Corporation's assistance is limited to engineered wood products supplied by SWC. Look to the design and engineering professionals to provide complete building plans that meet your design requirements.
Structural Wood Corporation is a wholesale distributor of Engineered Wood. Prefabricated Wood I-Joists are “I” shaped engineered wood structural members that are prefabricated using sawn or structural composite lumber flanges and OSB or plywood webs, bonded together with exterior type adhesives.
Typical I-joists for residential use are available in 9½, /8, 14 and inch depths. For I-joists over 22 inches in depth, the design should consider the possible. But other engineered wood products, such as wood I-joists/beams and laminated veneer lumber (LVL), surfaced in the mids.
Even so, it was not until the early s that engineered wood became widely accepted, and continues to gain popularity as the material and system of choice in present day design and construction systems. Prefabricated wood l-joists: an industry overview Robert J. Leichti Robert H. Falk Theodore L. Laufenberg Abstract Wood I-beams, limited to special applications for many years and mass produced only since the late s, have become a preeminent component of light-frame floor and roof systems and are commonly termed “I-joists” as a re-sult.
The modulus of elasticity averaged 2, ksi (14 GPa), while the shear modulus was ksi ( GPa) for the bamboo OSB and ksi ( GPa) for the three-ply material. Design values are developed from the test results following a hybrid approach based on ASTM procedures for wood I-joists and whole bamboo poles.
I-joists provide greater stability with 33% more stiffness than most building codes require. Most trusses are designed to meet building code requirements of L/ live load deflection, while WIDE OPEN™ I-joists are engineered to L/ live load deflection.
In some manufactured floor trusses, the top chord is supported at intervals as much as. Wooden I-joists have been called by several terms in the wood product industry and in the fire service, including wooden I-beams, composite wooden joists, plywood I-beams.
Engineered Wood Products. Structural has a complete line of engineered wood products for every application. I-joists save builders time, and therefore money. I-joists are typically pre-cut in two-foot increments and shipped to the job, minimizing job site waste.
I-joists can be trimmed and fastened with traditional framing tools and fasteners. A total of four-point quasi-static bending tests were performed on m and m long wood I-joists.
