Z & C Purlins
Z-Purlin features one broad and one narrow flange allowing the two sections to fit together snugly, making them suitable for lapping Z sections of the same depth and different thickness can be lapped if any combination. Purlins and girts that are lapped form a structurally continuous line along the length of the building, a factor that contributes significantly to the reduction in building costs.
C-Purlin has equal flanges and may be used in single spans and unlapped continuous spans in the multi-bay building. Their freestanding stable shape allows easy handling and storage and is easily adapted for use in small and medium-sized buildings as a structural framework.
Materials: Z Purlin and C Purlin are roll-formed from a Galvanized, high strength, steel strip Conforming to ASTH A653, Grade D structural quality
Standard base steel thickness: 1.5 mm, 2mm, 2.5 mm and 3mm
