How Do You Find LVL Span Chart Tables?
To find laminated veneer-lumber span chart tables, visit Georgia-Pacific’s website at BuildGP.com. Download the product guide for GP Lam laminated-veneer lumber located in the engineered lumber section of the site. The guide offers charts for span measurements for both floor and roof construction as well as general instructions for using the engineered wood in home construction.
To determine the size of beams required to support a single floor only, use the floor beams chart. Find the total floor joist span in feet in the left column and the spacing of the columns or supports in the top row to locate the appropriate size and ply of the necessary beams. Use the allowable-uniform-floor-loads charts to calculate the maximum weight load that a floor can support. To use the chart, look up the span in feet in the left column and the size and ply of the engineered lumber in the top rows.
To determine the size of beams required to support a roof, use the chart that corresponds to the location and type of roof. Roofs over patio doors, garage doors or windows require different types of beams. To determine the load-bearing capacity of the roof, use the allowable-uniform-roof-loads charts. Use the non-snow chart for warm climates and the snow chart for colder climates.
