Z and C Purlin / Section

ALFAA 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.

ALFAA purlins, girts and eave struts are designed in accordance of the American Iron and Steel Institue (AISI) then cold formed design manual.

ALFAA sections may be used over single spans unlapped continuous and lapped continuous span in multi bay buildings.

ALFAA 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

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 accessories. No further fabrication required . Considerable savings in erection costs and time.

Holes & Cleats

Standard Hole for Zed section

Standard Hole for CEE Sections

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
