Application

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 center 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.

Typical Connection

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 , separate the purlins and wipe & dry it
