What Does Z60 Mean?
Z60 galvanized steel refers to a zinc coating designation defined in GB/T 2518 and EN 10346 standards. The “Z” represents zinc coating, while “60” indicates a total coating weight of 60 g/m² on both sides of the steel sheet. Under ASTM A653/A653M, Z60 is approximately equivalent to G20, with a total coating weight of about 0.20 oz/ft².

Z60 Galvanized Steel Manufacturer
Wanzhi Group operates professional hot-dip galvanizing lines to produce galvanized steel with Z30-Z275 g/m² zinc coatings, including Z60 galvanized steel coils, sheets, and strips. The products meet international and domestic standards, including ASTM A653/A653M, EN 10346, JIS G3302, and GB/T 2518. Z60 galvanized steel features a 60 g/m² zinc coating. It offers a balance of corrosion resistance, cost efficiency, and processing performance, making it suitable for construction, roofing, and industrial applications.
Common Zinc Coating Grades
- Z30-Z60: Light zinc coatings for cost-effective applications requiring basic corrosion protection.
- Z80-Z120: Common grades for roofing, construction, and general industrial applications.
- Z180-Z275: Higher zinc coatings for improved corrosion resistance and extended service life.


Z60 Hot-dip Galvanized Steel Manufacturing Process
- Raw Material Preparation: High-quality cold-rolled steel coils are selected as the substrate and inspected before production.
- Cleaning and Surface Preparation: The steel strip undergoes degreasing, rinsing, and surface activation to remove oil, oxides, and impurities.
- Annealing Process: The cleaned steel strip is annealed in a controlled atmosphere to improve mechanical properties and surface quality.
- Hot-dip Galvanizing: The steel strip passes through a molten zinc bath to form a uniform zinc coating. The coating weight is controlled to achieve Z60 (60 g/m² total coating weight).
- Zinc Coating Control: An air knife system adjusts the zinc layer thickness to ensure consistent coating weight and surface quality.
- Surface Treatment: The galvanized steel receives passivation, chromating, or oiling treatment to improve corrosion resistance and surface stability.
- Quality Inspection: Finished products undergo inspections including zinc coating thickness, surface quality, dimensional accuracy, and mechanical properties.
- Packaging and Delivery: The galvanized steel coils are packed with export-standard materials and prepared for shipment.

Z60 GI Steel VS Galvalume Steel
Z60 galvanized steel features a pure zinc coating for reliable corrosion protection. It offers good formability and cost-effectiveness for general applications. Galvalume steel features a 55% aluminum-zinc-silicon alloy coating. It combines barrier and sacrificial protection for enhanced corrosion and heat resistance. Galvalume steel generally provides longer service life in outdoor environments, while Z60 GI steel offers a cost-effective solution for general applications.
