Tips For Choosing The Suitable Purlin For Roof Framing
Hence it is necessary to have a strong and reliable material to build a durable roof. Purlin is one such material that helps building strong and durable roofs. Purlin is a strong horizontal beam used to provide structural support for roofs mainly in steel structure buildings. They are either supported on the rafters or the walls of the building.
Purlins are extremely important because they provide the required support to the roof, stabilize and strengthen the structure of the building and add additional support between the spans of individual framing bays. Owing to these reasons, it is essential to chose purlin wisely from the best purlin manufacturers after considering all your architectural/ structural needs. Hence, here are a few tips for choosing the suitable purlin for roof framing:
1. Pick The Perfect Material

A large part of the metal trusses consists of recycled material, superior tensile strength, highly durable, abrasion & corrosion resistant.

C and Z purlins are more prominent and are named so because they look like the respective letters in squared form. ‘Z’ & ‘C’ sections are accurately roll formed from high strength galvanized steel, cut to the length and are pre-punched to the required dimensions to provide efficiency in faster constructions. Each one has its own advantages and depends on your roofing type.
3. Purlin Installation
The installation of purlin is also an essential process of roofing. Installed on top of roof rafters and horizontally under the metal roof, purlin should be supported with an underlayment and vapor barrier.
4. Wielding Is Prohibited
Purlins should not welded or hot cut either. The material properties that provide high strength to the purlin is affected with heat produced in the welding process.
5. Purlin Supplier
