Z275 Hot Dipped Galvanized Steel Coil
Hot dipped steel coil Z275 is a steel product with a high zinc coating, and its zinc layer weight reaches 275 grams per square meter.
Hot-dip galvanized steel coil Z275 is mainly used to enhance the corrosion resistance of steel and is widely used in construction, automobiles, steel structures and other fields.
| Parameter category | Z275 standard value | Ordinary galvanized coil | Advantage comparison |
|---|---|---|---|
| Zinc layer weight (g/㎡) | Double-sided ≥275 | 60-180 | Corrosion resistance increased by 300% |
| Substrate thickness (mm) | 0.12-6.0 | 0.3-4.5 | Wider range of applications |
| Yield strength (MPa) | 220-550 | 140-320 | Structural strength increased by 40% |
|---|---|---|---|
| Salt spray test (h) | ≥1000 | 200-500 | Service life extended by 5 times |
| Environmental certification | RoHS/REACH | Conventional standards | No worries about exporting to the EU |
Production process
Hot-dip galvanizing, also known as hot-dip galvanizing, is a metal surface treatment process.
In this process, zinc ingots are melted at high temperatures and certain auxiliary materials may be added. Subsequently, the steel sheet to be plated (here, the Z275 specification steel sheet) is immersed in a galvanizing tank to cover its surface with a uniform layer of zinc.
This zinc layer can effectively reduce the degree of corrosion of the steel substrate and improve its corrosion resistance.
Applicability in all scenarios
Construction and Infrastructure: Hot-dip steel coil Z275 is commonly used in house construction, floors, gutters and enclosures.
Home Appliance Industry: Hot-dipped galvanized steel coil Z275 is suitable for the manufacture of pipes, cutting boards, gadgets, corrugated sheets, containers and fences, etc., meeting the use requirements under various complex and harsh environmental conditions.
Other Industrial Applications: Hot dipped galvanized steel coil 275g is also suitable for the manufacture of various industrial parts and equipment to ensure the stability and safety of the structure.
