Our Products >> Purlins
Purlins are widely used in pre-engineering buildings in place of conventional channel angles. Purlins are secondary members of steel structures which serve as the basic material of construction for fast-track projects. These purlins are categorized by high strength, yet low cost (as a result of the high strength to weight ratio). Purlins typically refers to roof framing members that span parallel to the building eave and support the roof decking or sheeting. We offer a wide range of standard C and Z purlins, hat sections, box section.
Purlins are generally available from 100 to 300 mm depth/height and 45 to 75 mm wide in several thickness with downturn lips (flanges).
Purlins are widely used in commercial, industrial and rural buildings, steel structures, sheds and awnings as well as in racking and wall framings.
Z and C made of Hot Rolled Coils are degreased, phosphated and then primer finished with Zinc Chromate Red Oxide Paint- matching test requirement of IS : 4777 and IS : 2074.
Special Treatment to combat severe atmosphere corrosion can be offered.
Multicolor Offers C & Z in Galvanised coated Steel in 120GSM / 175GSM / 275 GSM Coating per customer requirement for high corrosion environment.
ADVANTAGE OF C AND Z PURLINS :
- Fabrication and installation is easy, time saving and cost effective
- Z shapes are utilized in manner that allows flexural continuity between span
- Gives additional stability in lateral direction to the shed
- Excellent finish and elegance as compared to conventional channel
- Steeve purlin system ensures durability and rigidity of structure
- Due to availability in various depths, width and thickness which gives architects the freedom to select economical sections for the project
- Purlins usually delivered with holes punched at any position on the web & flange as required, this facilitates supplied material to be ready to use on site arrival thus saves time
- ●Capsule Punching dimension: 18mm X 35mm
- Round Punching dimension: 14mm X 16mm
