Certified Roof Trusses

Our company, Lumbercraft, is certified by the Wood Truss Council of America (WTCA) and the Truss Plate Institute (TPI). Lumbercraft has a quality control team that provides a minimum of three truss inspections per week, per setup location and per shift using the Plate Placement Method. Every quarter, WTCA reviews Lumbercraft’s inspections electronically, while TPI sends an inspector to perform random, quarterly inspections at our plant. We are committed to our customers, and our experienced and knowledgeable team is ready to help you with your next project.
