Our C/Z Purlins are lightweight, high-strength cold-formed steel sections designed to support roof panels and wall cladding in steel buildings. C purlins are suitable for simple-span structures and wall girts, while Z purlins can overlap at support points to provide greater continuity and load-bearing capacity for longer spans. Dimensions, thicknesses, lengths, hole patterns, and galvanized coatings can be customized according to project requirements. Featuring accurate dimensions, excellent strength-to-weight performance, easy installation, and reliable corrosion resistance, C/Z purlins are widely used in workshops, warehouses, factories, aircraft hangars, agricultural buildings, and commercial facilities.
