S350GD – Hot-dip galvanized structural steel

 

The hot-dip galvanized steel S350GD in accordance with the EN 10346 standard is a high-strength structural steel that has been specifically developed for demanding applications in structural engineering and building construction. With the material number 1.0529, the minimum yield strength Rp0.2 is 350 N/mm², placing S350GD in the upper strength classes of hot-dip galvanized structural steels. Hot-dip galvanizing ensures a homogeneous zinc coating on the surface, which protects the steel against corrosion in the long term. Thanks to six different coating variants – +Z, +ZF, +ZA, +ZM, +AZ and +AS – the material can be optimally adapted to the specific environmental and stress conditions.

Packaging and shipping

 

 

S350GD galvanized steel sheets/plates could bring the following benefits to your project:

 

Corrosion-Resistant – The zinc coating helps protect against rust, perfect for outdoor and humid environments.

Strong & Durable – 350 MPa yield strength, built to handle heavy loads and tough conditions.

Long-Lasting – Its corrosion resistance keeps going longer, cutting down on maintenance costs.

Easy to Work With – Simple to cut, bend, and weld, so it's ideal for various manufacturing processes.

Versatile – Used across industries like construction, automotive, and appliances.

Flexible Processing – Works well for both cold and hot forming, giving you more production options.

Light but Tough – Strong yet lightweight, great for applications where you need strength without the extra weight.

1) Where yield strength is defined, the values apply to the upper yield strength ReH.

2) For all steel types, with the exception of S550GD, a span of 140 MPa can be expected for the tensile strength.

3) Depending on the product thickness, the minimum values of elongation at fracture are reduced as follows: 0.50 mm < t < 0.70 mm (minus 2 units), 0.35 mm < t < 0.50 mm (minus 4 units), and t < 0.35 mm (minus 7 units).
