The S355 steel specifications are high yield non alloy steels.


S355 is a low carbon steel grade often used for application which require better mechanical properties than that of S275 grade. Commonly supplied in the as rolled condition it is used widely in the construction, manufacturing and offshore industries.


S355 steel profiles are available as multiple or one off pieces. Flame cut steel plates can be supplied surface ground and edge machined to your required sizes. All flame cut steel pieces are dressed before final inspection and despatch. If you have any special requirements please inform our sales staff when you enquire for flame cut steel profiles.


Surface grinding and edge grinding of S355 is available on all flame cut steel plates. This is carried out on Lumsden grinding rotary reciprocating table machines. After being flamecut pieces can be ground to clean up or cut plates can be Lumsden ground to size on thickness to an tolerance of +/-0.25mm. A tighter tolerance may be possible, please provide your required tolerances when enquiring with our sales team.
