Decks.com. Beam Span Chart Table

The span of a beam is dependent on a few variables. The species of lumber, size of lumber and the load it carries. Fewer posts on upper level decks are typically more desirable to the occupants and this drives the use of larger framing materials for longer spans. Beam span maximums are based on a maximum anticipated 【Get Price】

Sizing Engineered Beams and Headers Building and Construction

No matter what material we specify, beams must provide adequate strength, stiffness, and shear resistance. Structural ability of sawn- and engineered-wood beams are predicted through mathematical calculation. Formulas that determine the allowable span and size of a beam rely on a host of variables like species, grade, 【Get Price】

Understanding Engineered Wood Beam Options - Nishkian Menninger

Jun 28, 2017 Due its high allowable shear strength, LSL beams have capacity for larger penetrations than other engineered wood beam options. While not as strong as LVL or PSL beams, LSL is generally cheaper and are ideal for short spans. LSL is also ideal for use in rim conditions due to minimal shrinkage, cupping 【Get Price】
