ASTM A572 Grade 50 – Mechanical Properties (Hot Rolled Steel Coil)
| Property | Typical Value | Notes |
| Yield Strength (YS) | 345 MPa (50 ksi) min | Stress at which steel begins to deform plastically |
| Tensile Strength (TS) | 450–620 MPa (65–90 ksi) | Maximum stress steel can withstand before breaking |
| Elongation | 18–21% | Measured over 200 mm or 50 mm gauge length, indicates ductility |
| Modulus of Elasticity | 200 GPa | Standard for carbon/low-alloy steels |
| Hardness (Brinell) | 130–180 HB | Approximate range for hot rolled steel |
Notes:
- Hot rolled coil ensures uniform thickness and good surface quality.
- Suitable for structural, construction, fabrication, and industrial applications.

1️⃣ Bulk Cargo
works for large shipments. The coils are loaded directly onto ships or stacked with anti-slip pads between the base and the coil, wooden wedges or metal wires between coils and surface protection with rain-proof sheets or oil for rust prevention.
Pros: High payload, low cost.
Note: Specialized lifting gear is needed and condensation and surface damage must be avoided during haulage.
2️⃣ Containerized Cargo
Good for medium to small shipments. The coils are packed one by one with waterproofing and anti-rust treatment; a desiccant can be added in the container.
Advantages: Provides superior protection, easy to handle.
Drawbacks: Higher cost, decreased container loading volume.
Stable cooperation with shipping companies such as MSK, MSC, COSCO efficiently logistics service chain, logistics service chain are we to your satisfaction.
We follow the standards of quality management system ISO9001 in all procedure, and have strict control from packaging material purchase to transport vehicle scheduling. This guarantees the H-beams from the factory all the way to the project site, helping you build on a solid foundation for a trouble free project!
