Aluminum Zinc Alloy Coated Steel Sheet in Coil S350GD+AZ
Good corrosion resistance
Due to the presence of the galvanized layer, S350GD+AZ aluzinc coated sheet in coil can effectively resist the effects of the atmosphere, water and other corrosive media, and extend its service life.
Anti-ultraviolet
The galvanized layer can effectively reflect ultraviolet rays, prevent ultraviolet rays from damaging the sheet, and maintain the appearance and quality of the sheet.
Good processing performance
S350GD+AZ aluzinc coated steel sheet in coil can be cut, bent, welded and processed, which is convenient for construction and installation.
Environmental protection
S350GD+AZ aluzinc coated roll is an environmentally friendly material. No harmful substances are produced during its production process and it can be recycled and reused after being discarded.
Composition
Ordinary galvanized sheets often rust in 3-5 years in coastal or industrially polluted areas, while S350GD+AZ aluminum zinc alloy coated steel sheet in coil uses 55% aluminum + 43.4% zinc + 1.6% silicon alloy coating technology to improve the anti-corrosion performance to 2-6 times that of ordinary galvanized sheets, making it the preferred material for high-end projects.

In the fields of industrial construction, warehousing and logistics, agricultural facilities, etc., the weather resistance and service life of steel directly affect the project cost.
Analysis of the core advantages of products
1. Excellent corrosion resistance
Salt spray test data comparison table
| Coating type | Red rust appearance time (hours) | Applicable environment |
|---|---|---|
| Ordinary galvanized coil | 500-800 | General dry area |
| S350GD+AZ | 1500-3000 | Coastal/industrial/high humidity environment |
2. Excellent heat reflection performance
The aluminum-zinc alloy layer has a solar reflectivity of up to 80%, which can reduce the roof temperature by 15-20℃ compared with dark steel plates, significantly saving air conditioning energy consumption.
3. Strong mechanical properties
Yield strength: ≥350MPa
Tensile strength: 420-510MPa
Elongation (A80mm): ≥18%
4. Economic advantage
Through double-sided coating weight control (50-150g/㎡), material cost optimization is achieved while ensuring anti-corrosion performance, and the cost of the entire life cycle is reduced by more than 40%.
Application
Construction field: S350GD+AZ aluminum-zinc steel coil is widely used in the construction field for the manufacture of roofs, walls, doors and windows. Its beautiful appearance and excellent anti-corrosion performance greatly extend the service life of the building. In addition, S350GD+AZ aluminum-zinc steel plates also have good thermal insulation performance, which can effectively reduce the energy consumption of buildings and conform to the concept of energy conservation and environmental protection.
Home appliance field: S350GD+AZ zinc coated aluminum coil is widely used in the manufacture of housings and parts for home appliances such as washing machines, air conditioners, and refrigerators.
Automobile field: S350GD+AZ galvanized steel coils are used in the manufacture of automobile bodies, chassis, and compartments.
In harsh environmental conditions, such as humid, rainy or industrially polluted areas, S350GD+Z al-zn coated steel coil demonstrate extraordinary durability.
Its galvanized layer can effectively isolate the steel plate from direct contact with moisture, oxygen and corrosive substances in the external environment, thereby significantly reducing the corrosion rate and extending the service life.
This is especially important for building structures that need to be exposed to outdoor or harsh environments for a long time, such as roofs, walls, awnings, etc., which can save maintenance costs while ensuring structural strength.
How to choose the appropriate specifications?
1. Environmental adaptation principle
C1-C2 environment (ordinary inland): AZ70-100
C3-C4 environment (industrial/coastal): AZ120-150
C5 environment (high corrosion area): AZ150+passivation treatment
2. Mechanical properties matching
Single-story building: S250GD+AZ
Long-span structure: S350GD+AZ
Heavy-duty plant: S550GD+AZ
3. Processing technology recommendations
Stamping: Recommended coating below AZ100
Roller forming: Adapt to all coating specifications
Welding processing: Plating compensation amount needs to be reserved
