Product introduction
◆ Application
S235JR Z60 galvanized steel sheet is a steel sheet coated with a layer of zinc on the surface of S235JR steel sheet. Z60 is one of the most commonly used coating types in manufacturing and construction industries.
Typical applications of S235JR Z60 galvanized sheet metal include:
Building elements such as steel structures (purlins and girders);
Steel frame decoration: painted rainwater pipe fittings;
Auto parts and body panels;
pipes and profiles;
engineering components;
Household appliances (washing machine frames and panels, cooker trays, clothes dryers, speaker stands, etc.);
Industrial products (oil pumps, oil tanks, heat exchangers, fan housings, trapezoidal profiles, cable tray systems);
Electronics and agricultural machinery components.
