These values have been developed through intensive laboratory testing both during the initial product development stage at the Advanced Engineered Wood Composites Center at the University of Maine (www.aewc.umaine.edu) and on a continual basis at the Forest Product Laboratory at Mississippi State Unversity. We have broken in excess of 800 beams. (http://www.cfr.msstate.edu/generalinfo/facilities/forest_products).

Daily destructive tests are preformed on the product as part of our continuous quality control.

In addtion each billet (the 1' wide laminated composite element that is bolted together to make the mats) is proof loaded after machining and drilling operations. During the proof loading process each billet is loaded to 150% of the allowable design load. For example if we publish load tables that allow the engineer to apply a 20,000 lb load to a 4.5" think by 4" wide mat that is spanned over an 11' clear span, we load the mat to 30,000 lb prior to leaving our manufacturing facility. All product is proof loaded to 150% of allowable design value.
