Specifications
LCP C & Z Purlins and LCP Girts are manufactured from G240 MPa, G345 MPa Steel ranging from 1.6mm thick to 3.15mm thick) with a minimum Z120 galvanized coating (120g/m2) and a maximum of Z275 galvanized coating (275g/m2). All purlins and girts shall be LCP C & Z Purlin sections, supported by submission of effective section properties, purlin capacity calculations and a performance warranty, produced and detailed for this project.
All cold-formed sections conforming to AS 1397 (or equivalent), with zinc coating from Z120 (120g/ m2) to zinc coating of Z275 (275g/ m2) having a minimum yield strength of 240 MPa to maximum yield strength of 345 MPa. All sections should be installed in accordance with the manufacturer’s instructions with particular regard to bolt locations on both web and flanges and lap sizes of 15% span. For more information on appropriate purlin section and other coatings, please contact LCP Building Products Pvt. Ltd., Technical Department.
Direct contact between galvanized LCP C & Z Purlin with other dissimilar material, for example copper pipe (bi-metallic corrosion) or treated timber (chemical corrosion) must be avoided to prevent premature corrosion.
