- John
Hot-dip galvanized S320GD steel is a versatile and durable material. It is dependable for building structures and serves as a durable option for exterior use.
SteelPro Group, a leader in the steel industry, provides high-quality S320GD steel products tailored to meet the diverse needs of our clients. Our products offer exceptional value and performance.
S320GD Hot-dip Galvanized Steel Description
Hot dip galvanized S320GD steel is a high-strength steel. “320” indicates the minimum yield strength of 320 MPa. S320GD steel is widely recognized for its excellent formability, strength, and superior corrosion protection. It can be produced through hot rolling and cold rolling, with a hot dip galvanizing treatment applied. It is extensively utilized in fields such as the vehicle manufacturing and building industries.
SteelPro Group provides S320GD in the form of coils and strips, ensuring high-quality material for diverse projects.
S320GD Equivalent Grades
S320GD is equivalent to the European standard EN10346:2015 grade 1.0250.
SteelPro Group manufactures S320GD steel in compliance with EN10346:2015 and other international standards, ensuring consistent quality, durability, and corrosion resistance
S320GD Galvanized Steel Coil Chemical Composition
| Element | Maximum Content (%) |
| Carbon (C) | 0.2 |
| Silicon (Si) | 0.6 |
| Manganese (Mn) | 1.7 |
| Phosphorus (P) | 0.1 |
| Sulfur (S) | 0.045 |
S320GD Galvanized Steel Coil Mecahmical Properties
| Property | Value |
| Tensile Strength (Rm) | 290 – 390 MPa |
| 0.2% Proof Strength (Rp0.2) | ≥ 320 MPa |
| Minimum Elongation (Lo = 80 mm) (A) | ≥ 17% |
Note:
The minimum elongation requirement varies with thickness:
- 0.5 mm < t ≤ 0.7 mm: The minimum elongation is reduced by 2% compared to the listed value.
- 0.35 mm < t ≤ 0.5 mm: The minimum elongation is reduced by 4% compared to the listed value.
- t ≤ 0.35 mm: The minimum elongation is reduced by 7% compared to the listed value.
The tensile strength range for this grade can vary by up to 140 MPa, depending on processing conditions and coating specifications.

S320GD Steel Coil & Strip Coatings
| Coating Designation | Total Coating Mass (g/m², both sides) | Coating Thickness (µm per side) |
| Z100 | 100 | ~7 |
| Z140 | 140 | ~10 |
| Z200 | 200 | ~14 |
| Z275 | 275 | ~20 |
| Z350 | 350 | ~25 |
Key Considerations:
- A thicker coating improves protection against corrosion, making it perfect for demanding outdoor conditions.
- Lower coating weight is often chosen for indoor applications or painted surfaces, where additional protection is unnecessary.
- The coating is applied uniformly during the hot dip galvanization, ensuring consistent protection across the steel surface.
SteelPro Group offers customized coating options to meet specific industry needs, ensuring optimal performance in construction, automotive, and manufacturing applications.
