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 →
Structural Steels: S235, S275, S355 (2) – Chemical Composition
The Chemical composition of Structural Steels is extremely important and highly regulated. It is a fundamental factor which defines the Mechanical properties of the structural steels material. In the following table you can see the Max % levels of certain regulated elements present in European Structural steels grades S235, S275 and S355. read more →
Structural Steel: S235, S275, S355 (1)
Structural steel is a standard construction material, made from specific grades of steel and formed in a range of industry standard cross-sectional shapes (or ‘Sections’). read more →

Definition of Mild Steel
Mild steel is the least expensive of all steel and the most common steel used. Used in nearly every type of product created from steel, it is weldable, very hard and, although it easily rusts, very durable. read more →
