S235 Structural Steel: Yield Strength and Properties

S235 Structural Steel has a specified minimum yield strength of 235 megapascals. The numbers below are the ones design and site work reach for.

Minimum tensile strength360 to 510 MPa
Elongationat least 26 percent
Density7,850 kg per cubic meter
Elastic modulus200 to 210 GPa
Typical uselight framing, secondary members, general fabrication

Notes for design and site

S235 is the gentle end of structural steel: easy to weld, easy to bend, hard to break badly. Its low strength rarely governs sections sized for stiffness or buckling anyway, which is why purlins, handrails, and light frames stay S235 while primary members moved on. The number 235 applies up to 16 millimeter thickness and eases downward beyond.
