Types of Steel

The steel produced by our company mainly include the following types

S350GD+ZAM275 Zn-Al-Mg Alloy Steel Strip
Due to the presence of aluminum and magnesium elements, aluminum will form a dense aluminum oxide film on the surface. Magnesium can enhance the cathodic protection during the cutting edge corrosion process, which greatly improves the corrosion resistance of the alloy strip steel, which is several times or even higher than that of ordinary pure galvanized sheet, and can effectively resist various harsh environments.

DX51D+Z80 Galvanized Steel Strip
Galvanized steel strip is a steel product that is made by coating a layer of zinc on the surface of cold-rolled or hot-rolled long strip steel plate through a specific process. The thickness of the galvanizing can be customized according to customer needs, ranging from 5um to 60um.

SPHC Pickled Steel Plate
Pickled strip steel is a steel product obtained by removing the surface oxide scale from hot-rolled strip steel through the pickling process. The surface oxide scale not only affects the appearance of the steel, but also has adverse effects on subsequent processing and performance. Pickled strip steel can effectively solve these problems.

Q235B Cold Rolled Strip Steel
Q235B cold-rolled strip steel is a steel product made from hot-rolled strip steel and rolled into finished products at room temperature through a cold rolling mill. Among them, "Q" represents yield strength, "235" represents the minimum yield strength of 235MPa, and "B" represents the quality grade.

Q235B Hot Rolled Strip Steel
Brand meaning: "Q" stands for yield strength, "235" means that the minimum yield strength of this steel is 235MPa, and "B" stands for quality grade, which requires it to pass the impact test at room temperature (20°C) and have a certain impact toughness.

Benefits of Steel

S350GD+ZAM275 Zn-Al-Mg Alloy Steel Strip
S350GD+ZAM275 Zn-Al-Mg alloy steel strip have many advantages, including:

Strong corrosion resistance:Due to the presence of aluminum and magnesium elements, aluminum will form a dense aluminum oxide film on the surface. Magnesium can enhance the cathodic protection during the cutting edge corrosion process, which greatly improves the corrosion resistance of the alloy strip steel, which is several times or even higher than that of ordinary pure galvanized sheet, and can effectively resist various harsh environments.

Cut self-healing property:It has a unique self-healing function at the cut and punch position, and does not require subsequent treatment. It overcomes the inherent defect of traditional coated plates that are prone to rust at the cut, and can maintain good corrosion resistance during long-term use.

Good processing performance: It has good welding processing performance, paint adhesion and spot welding performance, etc. It can adapt to various cold bending, stamping and other processing methods, and can meet the processing needs of different industries.

Good thermal stability:It can withstand a certain high temperature and has good thermal stability. It can be used in some environments with temperature requirements.

Environmental protection and energy saving:It has passed a number of environmental protection tests and meets environmental protection requirements. It is a new type of environmental protection and energy-saving material.

DX51D+Z80 Galvanized Steel Strip
DX51D+Z80 galvanized steel strip have many advantages, including:

Corrosion Resistance:One of the primary benefits of galvanised steel strips is their exceptional resistance to corrosion. 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.

Durability:Galvanised steel strips are highly durable, capable of withstanding harsh conditions and heavy usage. 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.

Key Differences Between Hot Rolled Steel And Cold Rolled Steel

Surface Quality

Hot rolled steel has the tendency to have rough surfaces and edges, which need decarburisation or other specific treatments to eventually prepare it for use in production operations. In contrast, Cold Rolled steel tends to have a smooth and shiny surface that permits it to be used as-is in diverse product operations.

Material Hardness

The process of cold rolling produces steel with much-enhanced hardness and strength in comparison with steel produced by the process of hot rolling.

Internal Stress

The enhanced hardness and material strength produced by the process of cold rolling come with greater internal stresses. These stresses need to be relieved prior to processing of the material, failing which the final product or part may experience warping.
These two primary types of steel must not be confused with the grades or technical specifications that are used for the classification of steel based on physical characteristics and composition. Steel can be hot or cold rolled irrespective of its grade or metallurgical specifications.

FAQ

Q: What is aluminum zinc alloy coated steel?

A: 55% aluminum-zinc alloy coated steel is cold-rolled carbon steel with a continuous hot dip process metallic coating composed of: 55% aluminum, 43.4% zinc, and 1.6% silicon. The alloy coating is applied to both sides of the steel sheet.

Q: Does zinc Aluminium alloy rust?

A: All zinc-based alloys demonstrate excellent resistance to corrosion across a variety of environments. The presence of aluminum in these alloys significantly enhances the well-established corrosion resistance of zinc, which constitutes the primary component of the alloys.

Q: What not to use with galvanized steel?

A: Zinc and Steel (Stainless or Galvanized): Zinc is anodic to both stainless and galvanized steel, leading to rapid corrosion of zinc. Steel and Brass/Bronze: Steel is anodic to brass and bronze, causing the steel to corrode in the presence of these metals.

Q: What is the life expectancy of galvanized steel?

A: These coatings are formed by dipping the metal into molten zinc, which creates a thick, durable layer of zinc on the surface. According to industry standards, hot-dip galvanized coatings can last up to 50 years in rural environments and up to 25 years in more corrosive environments, such as coastal regions.

Q: What are cold rolled steel strips used for?

A: These materials are used in applications ranging from simple sections to complex deep-drawn parts. Cold-rolled steel strip is used in the household appliance industry in washing machines, dishwashers, tumble dryers, refrigerators, ranges and hot water tanks.

Q: How do you protect hot rolled steel?

A: Protect them from exposure to moisture, rain, or other environmental factors that can accelerate rust formation. Use plastic or metal strapping to secure the bundles during transit to maintain their rust-free condition.
