Introduction

Another form of Z purlin is stronger than C purlin and is mostly used together at joints and overlaps. Z purlins are horizontal beams that are built to shape a building shell structure’s roof and wall joists. They sit between the roofing sheets and the building, acting as sheet support to ensure that it is firmly attached and secure in place. Due to its relatively high flexibility and lightweight properties Z purlins are most commonly used in agricultural and industrial buildings which make them easily adapted for use in a variety of different sizes.
