Structural Steels S235, S275, S355, S420 and Their Properties
Structural steels are the most widely used among steels because of their sufficient qualities and comparatively low price. This combination makes them useful in different sectors. Every year, about 25% of structural steels are used in the construction of buildings. Mechanical engineers favour it when building machinery that does not have many special needs like high durability or resistance to heavy loads.
