Purlins
ABOUT Z & C PURLINS
MATCON purlins girts & eve struts are secondary structural members used to support the wall and roof panels. Alfaa purlins are used on the roof, girts are used on the walls and eve struts at the intersection of side walls and roofs.MATCON purlins, girts and eave struts are designed in accordance of the American Iron and Steel Institue (AISI) then cold formed design manual.
MATCON sections may be used over single spans unlapped continuous and lapped continuous span in multi bay buildings.
MATCON Z&C purlins are available in two Standard Finishes i.e., Red Oxide, Galvanized

Advantages
Economy
- Savings in steel consumption upto 50% and savings in cost upto 30%
- Savings of transportation & handling, erection and fabrication costs
- No wastages, No surplus left-overs, since sections are supplied in exact required lengths
Design
- High strength, section versatility & wide range of choice
- Having their shear centre within the section, less liable to twist
- Permit increased truss-spacings & larger bay centres thus reducing foundation costs and overall weight of the structure
- Sleeve system to exploit continuity concept for larger spans
- Empirical design rules apply, hence no design problems
- Excellent surface finish
- Less weight per unit length compared to conventional section without sacrificing the required structural efficiency
- Conforming to the requirements of IS-801, IS-811
Practical Advantages
- Ability to rotate 180 degrees and fit together
- A full range of fixing accessories is supplied. Therefore no extra material needs be procured
- Sections supplied are pre-painted hence prevents corrosion and promotes long life
- Sections are pre-engineered, pre-punched and with complete

Handling and Storage
- Purlin requires appropriate care during storage on site
- The period between delivery and installation to be minimized
- Purlin should be neatly stacked on a ground on a slight slope so that water can drain out
- On open site condition purlins should be protected with water proof covers and condensation
- In case if the bundle of purlins becomes wet , seprate the purlins and wipe & dry it
