Typical Connection

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

Applications

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

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

Design

• High strength, section versatility & wide range of choice
• Having their shear centre within the section, less liable to twist

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.
