Finish

Finish Type
Details
Galvanized G60
Zinc coating of 0.6 oz/ft². Recommended for general environments.
Galvanized G90
Zinc coating of 0.9 oz/ft². Ideal for highly corrosive environments.
Prime-Painted
Provides a base coat for additional protection or paint adhesion.
Bare Steel
Unfinished; typically for indoor use or controlled environments.

To ensure durability and long-term performance, Z Purlins are available in various finish options, including galvanized (G60 and G90) and prime-painted coatings. The galvanized finish delivers outstanding corrosion resistance, with G90 offering a thicker zinc layer for added protection in moist or chemical-exposed environments. The prime-painted option features a protective base coat, making it suitable for projects that require additional paint or custom coatings. These finishes greatly extend the lifespan of Z Purlins, providing consistent and reliable performance in demanding commercial and industrial settings.
