Galvanized steel strip
We use high quality hot rolled coil as raw materials for producing cold rolled after pickling,continuous rolling, degreasing, annealing, skin pass, slitting etc. Good surface quality and high density can be widely used for food-grade tin plate, galvanized plate,house-hold appliance, building materials,electronics, automobile manufacture,petroleum chemical industry and architecture fields.

Production Process
Galvanized Steel Strip Production Process
Our galvanized steel strip is produced through a continuous hot-dip galvanizing line, ensuring stable coating thickness, strong adhesion, and consistent mechanical performance.
Raw Material Preparation
High-quality cold rolled coils are selected as base material.
Cleaning & Annealing
Surface impurities are removed and steel is heat-treated for better coating adhesion.
Hot-Dip Galvanizing
Steel passes through molten zinc bath forming a protective coating.
Air Knife Control
Precise air knife system controls zinc coating thickness.
Cooling & Surface Treatment
Coils are cooled and treated with chromating or oiling as required.
Slitting & Packing
Steel coils are slit to required width and packed for export.
Competitive Advantage
1. Corrosion Resistance: The zinc coating effectively isolates the steel substrate from corrosive elements such as oxygen and moisture. Even if the surface is slightly scratched, zinc will corrode preferentially, thereby protecting the underlying steel. Its corrosion resistance is typically more than ten times higher than that of ordinary carbon steel coils, making it especially suitable for harsh environments such as humid or coastal areas with salt spray and industrial atmospheres.
2.Workability and Aesthetics: Galvanized steel strip generally offer excellent formability and weldability, facilitating subsequent processing and manufacturing. At the same time, the surface is smooth and uniform with a silvery metallic luster and an attractive appearance, allowing it to be used directly in applications where aesthetics matter—such as roofing, wall panels, and home appliance exteriors—without the need for additional painting.
3.Cost Efficiency and Environmental Benefits: Although the initial procurement cost of galvanized steel strip is higher than that of carbon steel, their long service life and minimal maintenance requirements (no frequent repainting for rust prevention) can lead to lower overall lifecycle costs. From an environmental perspective, zinc is recyclable, and its use reduces VOC (Volatile Organic Compounds) emissions generated from repeated maintenance painting.
