S355 is a high-strength low-alloy structural steel (HSLA steel) produced through a hot-rolling process. Where:

S stands for Structural Steel

355 represents a minimum yield strength of 355 MPa

Simply put, S355 is stronger than ordinary structural steel while maintaining good workability. This means:

Thinner steel plates achieving the same load-bearing capacity

Lighter structural weight

Lower material procurement costs

Higher engineering safety factor

For large steel structure projects, reducing steel usage by just 10%-20% can potentially save tens or even hundreds of thousands of dollars in costs.

As a high-strength structural steel in the European standard EN10025, S355 steel plate not only has a yield strength of over 355MPa, but also excellent weldability, processing performance and low-temperature toughness, making it a widely used structural material by builders, equipment manufacturers and engineering contractors worldwide.

What are the grades of S355 hot-rolled steel plate?

S355JR
S355J0
S355J2
S355K2
S355N
S355NL

Higher yield strength means: The thickness of the steel plate can be reduced to achieve the same load-bearing capacity. For large projects, this directly reduces overall procurement costs.

S355 has a low carbon content, resulting in:

Less susceptibility to cracking during welding

Stable weld quality

High welding efficiency, Supports: MIG welding, TIG welding, Submerged arc welding, CO₂ gas shielded welding

Ideally suited for mass production in steel structure processing plants.

S355 steel plates can be: Laser cutting, Plasma cutting, CNC machining, Bending, Drilling

Meeting the production needs of various complex structural components.

For projects such as bridges, wind power, and port equipment, low-temperature impact resistance is crucial.

S355J2 and S355NL maintain good toughness and safety in low-temperature environments.

High-strength structural design means: Less deformation, Better fatigue performance, Lower long-term maintenance costs

This is especially important for projects requiring long-term operation.
