Galvanized Steel Coil
Need assurance on the verified Mechanical Properties Of S550GD? You've come to the right place. As a direct factory with 20 years of structural steel experience, GNEE Steel shares our testing processes for Mechanical Properties Of S550GD in S550GD Galvanized Steel Coil-plus compliance documents and factory prices.
Galvanized Steel Coil
S550GD galvanized steel coil is a high-strength structural material defined by EN 10346. Its reliable performance depends on strict verification of mechanical properties, which determine load capacity, flexibility, and durability.
Unlike generic galvanized coils, S550GD Galvanized Steel Coil requires specialized testing to confirm its enhanced mechanical properties, especially the ≥550MPa yield strength that sets it apart from lower grades.
Testing Standards for Mechanical Properties Of S550GD
GNEE Steel follows international standards to test Mechanical Properties Of S550GD, ensuring accuracy and compliance for S550GD Galvanized Steel Coil:
| Mechanical Property | Testing Standard | Key Test Parameters |
|---|---|---|
| Yield & Tensile Strength | EN ISO 6892-1 | Test speed: 2 mm/min; Temperature: 23±5°C |
| Elongation | EN ISO 6892-1 | Gauge length: 80mm; Calculated after fracture |
| Impact Toughness | EN ISO 148-1 | Temperature: -40°C; Specimen type: V-notch |
| Bend Strength | EN ISO 7438 | Bend angle: 180°; Mandrel diameter: 2×thickness |
| Hardness | EN ISO 6506-1 | Load: 3000N; Indentation time: 10-15 seconds |
These standards ensure test results are comparable and reliable globally.
Step-by-Step Testing Process for Mechanical Properties Of S550GD
GNEE Steel uses a systematic process to verify Mechanical Properties Of S550GD for every batch of S550GD Galvanized Steel Coil:
1. Sample Preparation
Cut specimens from the start, middle, and end of each coil to ensure representativeness.
Remove zinc coating from test areas (except for bend tests) to avoid interference.
Machine specimens to meet standard dimensions (e.g., 150mm×25mm for tensile tests).
2. Tensile & Elongation Testing
Mount specimens in a universal testing machine (UTM) with 1000kN capacity.
Apply gradual tension to measure yield strength, tensile strength, and elongation.
Record stress-strain curves for detailed performance analysis.
3. Impact Testing
Cool specimens to -40°C in a temperature-controlled chamber (±2°C accuracy).
Use a Charpy tester to strike specimens with a 300J pendulum.
Measure energy absorbed during fracture to determine impact toughness.
4. Bend & Hardness Testing
Perform 180° bend tests to check ductility and crack resistance.
Conduct Brinell hardness tests at three points per specimen for consistency.
Document all results in a batch test report.
