Z Sections
Hot-rolled and cold-formed Z-purlins
Z sections are structural members with a Z-shaped cross-section, available in hot-rolled and cold-formed (galvanised) versions. The lapped Z-geometry allows continuous span construction at supports, making them the dominant purlin and side rail in modern industrial buildings.
