EC73
- The primary building blocks of our truss system is ¢Ù C-Section ¢Ú Batten .
- The type of building, roof pitch, roof length, wind load and rain density are some of the deciding factors determining the design of our roof truss system.
D = depth , t = thickness (TCT) , b1 = top flange , b2 = base flange , s = lips
