Cold formed ‘Z’ and ‘C’ shaped members may be used as secondary structural elements to fasten and support the external cladding.

Cold-Formed Roof Purlins, Wall Girts, Eave Struts – All the members having section sizes varying from 150mm to 300mm depth are made from 120 GSM to 275 GSM GI coils confirming to ASTM-A-653 GRADE 50 or equivalent to yield strength of 345 MPA. ‘C’ and ‘Z’ Section Purlins, Girts, Struts are available in thickness ranging from 1.5mm to 3.0mm.

• Saving up to 40-50% weight of the structural steel and 25-30% in cost when compared to hot rolled sections.

• Saving up to 35-40% in weight and 20% in cost when compared to hot rolled Purlins.

• Truss spacing can be increased, hence less numbers of trusses, columns and foundations resulting in further economy.

• The Purlins are supplied in required lengths with pre-punched holes. Hence, reduction in constrained time and cost in fabrication & erection and no wastage.

• Purlin erection is easier than conventional options.

• Close tolerances on sectional dimensions due to process of cold roll forming.

• Low transportation cost due to reduced weight.

• High versatility, durability and uniform quality
