The construction and infrastructure sectors continue to rely heavily on galvanized steel due to its durability, strength, and cost efficiency. Among the structural grades defined in EN 10346, S250GD+Z galvanized steel sheet stands out as a practical and widely used solution. GNEE STEEL supplies S250GD+Z galvanized steel sheets for projects requiring dependable mechanical performance and corrosion resistance.
S250GD+Z is classified as structural quality steel with a minimum yield strength of 250 MPa. This makes it suitable for load-bearing applications while maintaining reasonable forming and fabrication capability.Unlike drawing-quality galvanized steel, S250GD+Z prioritizes strength and stability. It performs well under both static loads and long-term service conditions.
| Mechanical Property | Value |
|---|---|
| Yield Strength | ≥ 250 MPa |
| Tensile Strength | 330 – 410 MPa |
| Elongation | ≥ 19% |
| Standard | EN 10346 |
These characteristics make S250GD+Z galvanized steel sheet suitable for bending, welding, and assembly without compromising safety margins.
S250GD+Z galvanized steel sheets are commonly supplied with higher zinc coating weights to ensure long-term corrosion protection in outdoor environments.
| Zinc Coating | Typical Use |
|---|---|
| Z180 | General construction |
| Z275 | High humidity or outdoor exposure |
The hot dip galvanized coating significantly extends service life and reduces maintenance requirements, especially in roofing, fencing, and structural framing applications.
S250GD+Z galvanized steel sheets are widely used in steel structures, purlins, wall panels, cable trays, agricultural buildings, and light steel framing systems. The growth of solar mounting structures and prefabricated buildings has further increased demand for this grade.
GNEE STEEL ensures consistent mechanical properties, accurate zinc coating control, and flatness performance for every batch of S250GD+Z sheets. With extensive export experience, we support customers with reliable lead times and technical assistance.
Beyond S250GD+Z, GNEE STEEL offers higher-strength grades such as S280GD+Z and S350GD+Z, as well as DX54D+Z for forming applications and PPGI products. This complete product portfolio allows customers to source multiple steel solutions from a single trusted supplier.
