Engineered Wood Products


EWP includes a wide variety of wood structural products made by manufacturers all over the world. We work with manufacturers primarily in the US, Canada, and Europe, but also have clients elsewhere. We test, inspect and certify structural composite lumber [(SCL) including LVL, PSL and LSL], wood I-Joists, glued laminated timber, and cross-laminated timber (CLT) products that are marketed to the major wood-consuming markets of the world. We are experts in the relevant standards for this broad class of products (including ANSI, ASTM and JAS), and understand how building codes treat these products in a variety of applications.


We know how to work across borders—because we do it successfully every day. To learn more about the certification, inspection and testing services available for the EWP products you manufacture and market, please contact:
