Durable Galvanized Coil | Advanced Oil-Coated Steel Solutions

​Product Overview

Our ​galvanized coil is engineered for exceptional durability and corrosion resistance, making it ideal for electromechanical, construction, and industrial applications. Manufactured by leading ​galvanized coil suppliers, these ​steel coil galvanized products feature a transparent anti-rust oil coating for enhanced protection against harsh environments. With precise engineering and strict quality control, our coils deliver unmatched performance in demanding scenarios.

​Product Specifications

​Technical Properties & Performance

​1. Tensile Strength

The ​galvanized coil exhibits a tensile strength range of ​350–550 MPa, ensuring structural integrity under heavy loads. This is achieved through advanced cold-rolling and annealing processes, which refine the steel’s grain structure. High tensile strength makes it suitable for automotive chassis, roofing sheets, and machinery components requiring resistance to deformation.

​2. Bendability & Formability

With a minimum bend radius of ​1.5x thickness, our ​steel coil galvanized maintains integrity even after severe forming. The zinc coating’s ductility prevents cracking during fabrication, while the oil layer reduces friction during stamping or rolling.

​3. Identification & Grading

Coils are labeled per international standards (e.g., ​ASTM A653 or ​EN 10346), including:

• ​Coating Mass (e.g., Z275 = 275 g/m² zinc).
• ​Surface Treatment (e.g., Oiled, Passivated).
• ​Grade (e.g., DX51D, SGC400).

​4. Weight Calculation

Weight per square meter is calculated using:
Formula:
$\text{Weight (kg/m²)}=\text{Thickness (mm)}\times \text{Width (mm)}\times 7.85(\text{Density})$
Example: A 1.2mm-thick coil weighs ​9.42 kg/m².

​5. Causes of Stainless Steel Rusting

While our ​galvanized coil is rust-resistant, stainless steel may corrode under specific conditions:

• ​Environmental Exposure: Chlorides (e.g., coastal air) or acidic pollutants degrade passive oxide layers.
• ​Mechanical Damage: Scratches or abrasions expose raw steel to moisture.
• ​Chemical Contamination: Contact with iron particles or low-pH solutions accelerates oxidation.
• ​Coating Defects: Inconsistent galvanizing or oil application leaves vulnerable spots.

​Why Choose Our Galvanized Coils?

​1. Superior Corrosion Resistance

The ​steel coil galvanized undergoes a dual-protection process: ​hot-dip galvanizing (zinc layer) and ​transparent anti-rust oil coating. This combination blocks moisture, salt, and UV exposure, extending lifespan by 20–30 years.

​2. Precision Manufacturing

As trusted ​galvanized coil suppliers, we employ laser-guided cold-rolling mills and automated coating systems to ensure uniform thickness (±0.02mm tolerance) and flawless surface finishes.

​3. Customizable Solutions

Tailor coils to your needs:

• ​Custom Sizes: Non-standard widths or lengths.
• ​Surface Treatments: Oiled, chromated, or phosphated.
• ​Certifications: CE, ISO 9001, and RoHS-compliant options.

​4. Cost Efficiency

Reduced maintenance costs and long-term durability make our ​galvanized coil a sustainable investment for construction, HVAC, and agricultural machinery.

​Applications

• ​Electromechanical Systems: Motor casings, transformer shells.
• ​Construction: Roofing, wall panels, gutter systems.
• ​Automotive: Body panels, chassis components.
• ​Industrial: Storage tanks, conveyor systems.
