Purlins and rafters are the basic and inseparable part of the structural roof. Purlin is considered a part of the steel roof load transmitter. They tend to transmit life paths, dead loads and even wind loads on the roof. Most often this is considered as part of a large steel structure with a low level of permeability.
In the construction process, the purlin in truss starts the ring beam. The main wall plate is tethered to the beam with the help of bolts. After the wall plate is repaired, the roof structure becomes stronger. After the design is finished purlin is added to the rafters. Decking boards are followed by attaching to a retractable purlin. The ceiling is only a distance of at least twice three shades of purlins. The board is usually thick and a total length of eight feet.
