Galvanized Steel Strip Manufacturer in China
During the galvanization process, steel sheets or zinc steel coils undergo a treatment that applies a protective zinc coating to the surface, resulting in galvanized steel strips. This process creates a barrier between the steel and the surrounding environment, preventing corrosive substances from reaching the underlying steel. The zinc coating forms a sacrificial layer, shielding the steel from corrosion and extending its lifespan significantly.

Galvanized Steel Strip by Grades
Choose the galvanized steel grade you need, for any use, Delong always gives you the best solution.
Surface
Zero Spangle: An additional skin-pass process after the initial galvanization involves carefully applying tension to the steel strip as it passes through rolls. This additional step eliminates the crystalline spangle patterns typically seen on galvanized steel, creating a smooth and matte-like appearance.
Minimized Spangle: This finish has a smaller and less visible crystalline pattern compared to regular spangle. It is often used for applications requiring a more uniform appearance.
Regular Spangle: This is the most common finish, characterized by a visible crystalline pattern on the surface. It is created during the cooling process when the zinc coating solidifies.
Large Spangle: Spangles with a diameter larger than 3mm that can be distinguished by the naked eye are called large spangles. The internationally recognized optimal size is 8~12mm. It is widely used in construction, machinery manufacturing, home appliances and other fields.

Galvanized Steel Strip Properties
Cost-effectiveness
Galvanized steel strips’ long lifespan, low maintenance requirements, and resistance to corrosion ultimately reduce overall costs in the long run.The extended service life of Zinc steel coils translates into less frequent replacements and repairs, making them economically viable.
Durability
The zinc coating provides a robust protective layer, making the steel strips resistant to scratches, impacts, and abrasion. This durability ensures that Zinc steel coils maintain their structural integrity over an extended period, reducing the need for frequent replacements.
Corrosion Resistance
The zinc coating acts as a protective shield, preventing moisture, oxygen, and other corrosive elements from reaching the steel surface. This makes ideal for applications where exposure to harsh environments or moisture is common, such as outdoor structures or coastal areas.
Sustainable
They come in various thicknesses, widths, and lengths, allowing flexibility in design and application. Furthermore, manufacturers can easily form, weld, and manipulate galvanized steel strips, allowing them to be tailored to the desired shapes and sizes.
Galvanized Strip Production Process
1. Pickling and decontamination of the entire roll of strip steel to achieve a bright and clean surface.
2. Hot-dip galvanizing: After pickling, it is cleaned in the tank of ammonium chloride or zinc chloride aqueous solution or mixed aqueous solution of ammonium chloride and zinc chloride, and then sent to the continuous annealing furnace and then into the galvanizing tank for galvanizing.
3. The strip is galvanized and put into storage, and the galvanized layer can be customized according to customer needs.
4. If there is a requirement for the width, the can be processed into strips. Generally, the thickness of the toxicity file is 0.12-2mm.
Environmental Impact of Galvanized Steel Strips
It have a positive environmental impact due to their recyclability and sustainable production practices.
The widely recycled material used for galvanization is zinc. At the conclusion of galvanized steel’s service life, it can be easily recycled and repurposed into new steel products, reducing the demand for raw materials and minimizing waste.
Furthermore, efforts have been made to enhance the manufacturing processes for galvanized steel, reducing emissions and energy consumption. Ongoing initiatives are focused on improving the sustainability and efficiency of production, establishing Zinc steel coils as an environmentally responsible choice.
How long do galvanized steel strips last?
It have a lifespan that can exceed 50 years, depending on the environmental conditions and maintenance. The zinc coating provides excellent corrosion resistance, significantly extending the life of the steel strips.
Are galvanized steel strips suitable for outdoor use?
Yes, It is highly suitable for outdoor use. The zinc coating acts as a protective barrier, shielding the steel from moisture, UV rays, and other environmental factors. This makes them a reliable choice for applications exposed to outdoor conditions.
Can galvanized steel strips be painted?
Certainly, painting galvanized steel is possible. However, it is crucial to ensure that the surface is thoroughly cleaned and prepared before applying paint. For optimal adhesion and durability, it is recommended to use special primers and paints specifically designed for galvanized surfaces.
How are galvanized steel strips different from stainless steel?
It have a zinc coating applied to their surface, providing corrosion resistance. Stainless steel, on the other hand, is an alloy that contains chromium, providing inherent corrosion resistance throughout the material. Stainless steel does not require an additional protective coating and has a different appearance.
What is the typical thickness of galvanized steel strips?
The thickness of galvanised steel can vary depending on the intended application. However, common thicknesses range from 0.25mm to 6mm, with the most commonly used thicknesses falling between 0.8mm and 2mm. The manufacturing process allows for the accommodation of specific requirements through customization.
