Z275 Galvanized Steel Sheet is a type of steel sheet that has been galvanized to provide protection against corrosion. The "Z275" designation refers to the zinc coating weight, which means that the sheet carries a minimum average mass of 275 grams of zinc per square meter on both sides (140 g/m² each side for single-sided coating), according to international standards such as ISO 1461 or equivalent.

Ingredients:
1. Base Material: Similar to SPCC Galvanized Steel Sheet, Z275 sheets start with a base metal, usually mild or carbon steel, which provides the structural integrity and mechanical properties needed for various applications.
2. Zinc Coating: The key ingredient in Z275 Galvanized Steel Sheet is the zinc layer. This layer is applied through hot-dip galvanizing, where the steel sheet is immersed into a bath of molten zinc. As the steel cools, the zinc bonds chemically and metallurgically to its surface, forming a durable, protective layer.
Properties & Uses:
- Corrosion Resistance: The 275 g/m² zinc coating offers a high level of corrosion resistance, making it suitable for outdoor structures, harsh environments, and long-term use without frequent maintenance.
- Durability: With its robust zinc coating, Z275 Galvanized Steel Sheets are resistant to weathering, abrasions, and can withstand moderate impacts, thereby increasing their lifespan.
- Formability: While the thicker zinc coating may affect formability compared to thinner coatings, Z275 Galvanized Steel Sheets still maintain reasonable bendability and workability, allowing them to be used in manufacturing processes like roll forming, bending, and welding.
- Applications: Common uses include construction materials such as roofing sheets, wall cladding, guttering, and downpipes; infrastructure components like guardrails, telecom towers, and street lighting poles; industrial products including electrical enclosures, air conditioning units, and automotive parts where extended durability against corrosion is critical.
In conclusion, Z275 Galvanized Steel Sheets are a popular choice for professionals due to their enhanced corrosion protection and versatility, ensuring the longevity of the structures and components made from this material.
