• The primary building blocks of our truss system is  ① C-Section ② 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
