S355M Thermomechanical Steel Plates

Bridge made out of S355M structural steel plates from Dillinger

S355M is a thermomechanical rolled weldable fine grain structural steel to EN10025-4. We have a large stock of S355M from 10 – 100 mm. It has a steel number of 1.8834

Typically S355M steel plates are used in construction projects where weight is a premium. The thermo-mechanically rolled steel is appropriate for these circumstances as the additional alloying makes it stronger than conventional EN10025-2 steels

Stock plates can be delivered to customer across Asia on a CIF basis to all major ports including: Singapore, Port Klang, Surabaya, Jakarta and Laem Chabang

S355M Steel Plates Available Ex-stock

There is a good selection of S355M plates on an ex-stock basis for most project requirements.

Thickness: 8 – 100 mm
Width: Up to 3 metres wide
Length: Up to 12 metres long

Plates can come with either an MTC to either 3.1 or 3.2 to EN 10204

For customers in Europe S355M plate can be ordered direct from Dillinger or from stock from AncoferWaldram. The EN 10028-4 standard can be purchased from the BSI
