Products Description

Hot Dipped Galvanized Steel Sheet Manufacturer

No cutting corners on zinc weight. Accept SGS testing.

Hot dipped galvanized steel sheet is a type of steel product that has been coated with a layer of zinc to protect it from corrosion. The process involves immersing the steel coil into a bath of molten zinc, which forms a metallurgical bond between the zinc and the steel.

FAQ
Q: What is the HS Code for galvanized steel?
A: 721049. Please check local import tariffs before ordering from China.
Q: What is the service life of galvanized steel coils?
A: The lifespan depends on the application, environment, and zinc coating weight. For example, a Z275 galvanized roof in a marine environment typically lasts 5 years, while a Z180 cable tray indoors can last 15 years.
Q: How is the price of galvanized steel calculated?
A: Pricing is determined by the raw hot-rolled material costs, the specific zinc coating weight, as well as the width and thickness of the coil.
Q: Can galvanized steel sheets be oiled?
A: Yes, they can be oiled (typically 8-20g per square meter). Oiling helps prevent oxidation during short-term storage or transit.
Q: Is there quality inspection before loading?
A: Yes, all products undergo strict quality testing before packaging. Unqualified products are discarded. We welcome third-party inspections.
Q: What information is needed for a quote?
A: To provide an accurate quote, please specify the steel grade, width, thickness, coating weight, and the quantity in tons.
