EHONG STEEL –GALVANIZED STEEL STRIP

The core process of galvanized steel strip is "substrate + coating." It uses high-quality cold-rolled or hot-rolled steel strip as the substrate and, through a continuous hot-dip galvanizing process, firmly coats the substrate surface with a layer of zinc to produce a composite metal material. The primary objective of this process is to provide the steel with exceptional and long-lasting resistance to environmental corrosion, serving as an effective solution for material lifecycle management.

Comparison of Core Properties

Comparison Dimensions Galvanized Steel Strip
Core Properties Excellent corrosion resistance
Key Processes High-quality substrate + hot-dip galvanizing + post-treatment (optional)
Surface Characteristics Features zinc bloom (zinc-free option available); suitable for post-treatment such as passivation, oiling, and anti-fingerprint coating
Mechanical and Process Properties Substrate properties (e.g., yield strength, tensile strength) are influenced by the pre-galvanizing condition and post-galvanizing heat treatment; the coating itself has high hardness and significant brittleness
Primary Application Scenarios Suitable for applications with specific requirements for environmental corrosion resistance

Processing Procedures

Step 01
Cold Rolling
Cold-rolling galvanized steel coils to the required thickness to ensure dimensional accuracy.
Step 02
Coil Pretreatment
Treating the steel coils through cleaning, pickling, chromium plating, etc., to effectively remove surface contaminants such as oil and scale, improve surface cleanliness, and lay the foundation for subsequent galvanizing processes.
Step 03
Galvanizing
Galvanizing is performed using a galvanizing tank or spray coating system to uniformly coat the steel coil surface with a layer of zinc, ensuring strong adhesion between the coating and the substrate.
Step 04
Inspection
Key parameters such as product thickness, width, and zinc coating thickness are rigorously inspected to ensure the product meets quality standards.
Step 05
Cutting
The steel coils are cut to the required length and width according to customer specifications to meet the needs of various applications.
Step 06
Packaging
The cut galvanized steel coils are professionally packaged to prevent surface scratches and damage during transportation and storage, thereby protecting the product's appearance and performance.

 Main Applications

The use of galvanized steel strip has permeated various fields such as daily life, construction, and electrical appliances, making it an integral and inseparable part of our daily lives.

Daily Life
Primarily used in daily necessities such as water buckets, metal dustpans, chimneys, and kitchen range hoods, as well as in household applications like bathroom and kitchen drainage pipes and heating pipes, combining practicality with corrosion resistance.
Construction
Commonly found in roofing, wall cladding, roll-up doors, insulation casings for steel pipes, and water deflectors, it provides excellent protection for building facades and extends the structure's service life. Additionally, galvanized steel strip is widely used in steel frames for agricultural greenhouses and temporary construction structures.
Electrical Appliances
Used in household appliances such as refrigerators, washing machines, and vacuum cleaners, it offers excellent leak-proofing and protective properties, ensuring the stability and longevity of the appliances.

Classification of Tubing

Galvanized steel strip can be broadly categorized into two types based on application: tubing and profiles. Specific specifications and applications are as follows:

01
Tubing
Thickness: Generally 0.7–2.0 mm, with 1.0–1.6 mm being the most common
Zinc Coating: Approximately 280 g/m²
Application: Primarily used to manufacture various types of steel pipes to meet piping installation needs in different scenarios
02
Profiles
Thickness: Generally 2.0–4.0 mm
Zinc Coating: Primarily 180 g/m², customization available based on specific customer requirements
Application: Primarily used to produce C-channel, Z-channel, U-channel, and other profiled steel sheets, widely applied in building structures and other fields
