Structural Steel Applications: S235, S275, S355 (4)
Structural steels are used in many ways and their application can be diverse. They are particularly useful because they offer the unique combination of good welding properties with guaranteed strengths. Structural Steel is an extremely adaptable product and is often favoured by the engineer trying to maximise strength or s structure while minimising its weight. read more →
Structural Steel: S235, S275, S355 (3) – Yield Strength & Tensile Strength
The Mechanical Properties of Structural Steel are fundamental to its classification and hence, application. Even though Chemical Composition is a dominant Factor of the Mechanical Properties of steel, it is also very important to understand the minimum standards for the Mechanical Properties (Performance characteristics) such as; Yield Strength and Tensile Strength. read more →
