Introduction: Galvanized steel Z purlin is a common cold-formed thin-walled steel with a thickness between 1.6-3.0mm and a section height of 120-350mm. The processing material is hot rolled (painted) and galvanized.

In general, galvanized steel Z purlin must have large and small sides, and the large side is about 5mm higher than the small side. Because the installation of Z-shaped steel is basically continuous, the small side covers the large side. b. Due to the high requirements for raw materials and non-standard of raw materials, the finished products are not absolutely standard. The installation hole of Z-beam is generally required to be larger than that required by the drawings. For example: if the drawing is 12 holes, then the actual holes should be made into 14 holes. c. Z-shaped steel is suitable for large-span workshop because its installation is lap joint, and its strength and stability are better than C-type purlin. FAQ: Q: What鈥檚 your after-sale service?
