Galvanized Steel Coil A653
-
Physical Barrier
Isolates steel from contact with corrosive media.
-
Electrochemical Protection
Even if the coating is locally damaged, the zinc acts as an anode and preferentially corrodes, protecting the steel substrate.
-
Self-Healing
Zinc corrosion products (basic zinc carbonate) can slightly fill minor scratches.
| Thickness | 0.15mm - 3.0mm (thicker options available upon request) |
| Width | 600mm - 1500mm (slits available upon request) |
| Zinc coating grades | G30, G40, G60, G90, G115, G140, and other mainstream and high-zinc coating grades (please inquire for specific inventory availability). |
Corrosion resistance
Flexible zinc coating thickness: The A653 standard specifies different zinc coating designations (Gxx), such as G60 and G90, corresponding to different zinc coating weights (g/m²). This allows you to precisely select the required level of protection based on the corrosion environment of the end application (C1: mild indoor - C5: harsh industrial/marine), avoiding under- or over-protection.
Long-life guarantee: In typical atmospheric environments, the G90 zinc coating (275g/m² on both sides) provides decades of effective protection, significantly reducing lifecycle costs. It is an ideal choice for outdoor structures, guardrails, photovoltaic mounting systems, grain silos, and more.
Processability
Excellent Base Material Quality: Our A653 galvanized steel sheet in coil is constructed from high-quality, cold-rolled, low-carbon steel, offering an excellent balance of strength and toughness.
Strong Zinc Adhesion: Strictly controlled processes ensure a strong bond between the zinc layer and the steel base, preventing flaking or powdering during subsequent processing such as stamping, bending, and roll forming.
Smooth and Uniform Surface: The zinc layer boasts fine crystals and a high surface finish, creating an aesthetically pleasing finish that also facilitates subsequent finishing processes such as spray coating and lamination.
Surface Quality and Aesthetics
Standard Surface Treatment
A standard smooth surface is available, meeting most application requirements.
Special Surface Options: Spangle size control (Minimized Spangle / Regular Spangle) can be customized to meet different aesthetic or coating requirements.
Excellent Coating Substrate: A clean, uniform, and highly adherent zinc layer provides the perfect foundation for color coatings (PVDF, SMP, HDP, PE/Polyester, etc.), ensuring coating durability.
| Slitting | Precisely slit steel sheets to your exact width requirements. |
| Slab Cutting | We offer a flattening service, cutting steel coils into flat sheets to your desired length. |
| Special Zinc Coating/Material Requirements | We can assist with customizing production requirements by collaborating with steel mills. |
High Quality Materials
ASTM A653 galvanized sheet coil is made of high quality materials with good mechanical properties and corrosion resistance, suitable for a variety of industrial and construction applications.
Hot-dip galvanising process
The product is treated by hot-dip galvanising process, which effectively improves the corrosion resistance and durability of the product, and is suitable for outdoor environments or occasions that require long-term exposure.
Standard Specification
The standard covers different strength grades and thicknesses to meet the needs of various applications, including different specifications such as HSLAS-F 340 for different usage scenarios.
Reasonable price
The price of ASTM A653 galvanized steel plate is relatively reasonable and has a good cost-effectiveness, which is the preferred choice of many enterprises and individuals when choosing materials.
Applications
Construction: Metal roofing, wall systems (color-coated substrates), floor decking, C/Z-shaped steel, ventilation ducts, downspout systems, and building structural components (lightweight steel keels and trusses).
Industrial Manufacturing: Appliance housings (refrigerators, washing machines, air conditioners), computer cases, filing cabinets, office furniture, lighting, automotive parts (structural components, fuel tanks), granaries, and livestock equipment.
Agriculture: Greenhouse frames, breeding equipment, granary panels, and agricultural machinery components.
Infrastructure: Highway guardrails, noise barriers, cable trays, photovoltaic mounting systems, and municipal infrastructure (light poles and sign bases).
Why choose us?
Strictly Adhering to International Standards, Reliable Quality.
ASTM A653/A653M: This standard for hot-dip galvanized steel sheet and strip is widely recognized in North America and globally. It clearly defines key specifications such as material quality (base steel grade), mechanical properties, zinc layer weight/thickness, coating adhesion, and surface quality.
Material Certification (MTC) Available: Detailed quality documentation is provided with each shipment to ensure that the product meets your required specifications (e.g., SS Grade 33, 37, 40, 50, 80; HSLAS Grade 55, 60, 70, 80; or specific yield strength requirements).
Competitive Pricing: Leveraging our extensive procurement capabilities and sophisticated operational management, we offer customers the best pricing on galvanized coils in the market.
Transparent Quotation System: We provide clear and transparent quotations (weight, unit price, total price, delivery time, etc.) with no hidden fees.
Key Factors in Choosing the Right A653 Galvanized Coil
Clarifying the end use and environment: This is the key factor in selecting the zinc coating grade and material grade. High-grade zinc coatings (such as G90 and above) are essential for coastal, industrial, and high-humidity environments. Material grade (yield strength and tensile strength) should be considered for load-bearing structural components.
Precise specifications: thickness, width, length (flat), inner diameter, and zinc coating weight/code are essential for procurement. Providing accurate drawings or technical specifications greatly improves communication efficiency.
Surface requirements: Are there any special spangle requirements (no spangle, small spangle, or regular spangle)? Is the substrate color-coated? This will influence the production process and selection.
Certification requirements: Does the project require specific third-party certification (such as CE, JIS G 3302, EN 10346, etc.)? We can provide products that comply with multiple national standards.
Quantity and delivery time: Clarifying the required quantity and desired delivery time will help us provide the optimal solution (spot/futures).
