Galvanized sheets
Surface state: Galvanized sheets have different surface states due to different treatments in the coating process, such as normal zinc bloom, fine zinc bloom, flat zinc bloom, no zinc bloom, and phosphate treated surfaces. The German standard also specifies the surface level.

There are several advantages to using galvanized steel, including:
Corrosion resistance: Galvanized steel is highly resistant to corrosion and rust due to its zinc coating. This makes it a durable material for outdoor and marine applications, as well as in areas with high levels of moisture and humidity.
Longevity: The protective zinc coating on galvanized steel provides a long lifespan, which can help reduce maintenance costs and increase the product’s overall lifespan.
Cost-effective: Galvanized steel is relatively inexpensive compared to other corrosion-resistant metals like stainless steel, and its durability can help reduce maintenance and replacement costs over time.
Easy to work with: Galvanized steel can be easily cut, formed, and welded like regular steel, making it a versatile material for a variety of applications.
Aesthetic appeal: The unique appearance of galvanized steel, with its distinctive silver-gray finish, can be an attractive option for architectural and design applications.
Environmental sustainability: Galvanized steel is a sustainable material that can be recycled and reused, reducing the environmental impact of manufacturing and construction.
