What is a tji 210 joist?
Sold by lineal foot. Trus Joist® TJI® joists are lightweight, easy to work with, and deliver unmatched dimensional stability and performance. They are engineered to resist the bowing, twisting, and shrinking that can lead to squeaky or “soft” floors. 2-1/16 inches x 9-1/2 inches. Engineered for strength and consistency.
How far can you span a TJI joist?
According to TJI’s span table, switching to deeper 11-7/8 inch joists (a nominal 2×12), even when spaced at 19.2 inches on-center, enable you to go as long as 17 feet, 4 inches and still achieve L/480.
How far can an engineered joist span?
Joists are available in several depths and lengths and superior strength allows them to span up to 30 feet (TRIFORCE span tables).
What is a BCI Joist?
BCI® Joists are specially constructed I-joists with flanges made from strong VERSA-LAM® LVL (Laminated Veneer Lumber) with oriented stranded board webs and approved waterproof structural adhesives, providing outstanding strength and durability.
What are truss joists?
Joists are used in floors and as column support. The joist (also called Bandsill) supports the load which the floor is built to bear. It is like the skeleton a building. Trusses are of many types; the simplest is a planar truss which is used as a roof support system.

What is the difference between LVL and LSL?
LSL is typically less expensive than other engineered wood beams. Due to its high allowable shear strength, LSL beams have the capacity for larger penetrations than other engineered wood beam options. Laminated Veneer Lumber (LVL) is a commonly available engineered product that is manufactured similarly to PSL.
