Purlin roll is an important part of building which indirectly support the weight coming from roof. The architectural history about purlin has thousands of years. With the development of technology, the modern society mostly uses C and Z type of steel, which are stronger and durable. For many of us, purlin may be a unfamiliar word that never heard. However, no matter you is an engineer or just a common consumer who want to acquire some knowledge about the house you’re living. Reading this article may do some help to know building better?
Though purlin plays an irreplaceable role in supporting roofs, it does not directly sustain the whole weight of roof s. The main usage of purlin is that it can transmit the weight to steel frame of the building, which is simpler to assemble and recycle whereas traditional reinforced concrete architecture takes longer time to build and produce a lot of waste that definitely does harm to environment.
C steel is one of the most popular materials used for making purlin. Its special physical properties make it lighter and thinner. The surface of C steel is smooth and bright. Nevertheless, C steel has high strength and precision, which make it so popular in the field of architecture. Moreover, C steel can not only be used in constructing, but also in many light industries.
