SN490C Building Structure Steel Plate
SN490 steel plate is Japanese standard steel plate for building structure, there are (B, C) two grades, that is, SN490B structural steel, SN490C structural steel plate, SN490B/C steel plate implementation standard: implementation of YB4104 JIS G3136 BS7191 standard.
SN490B/C structural steel sheet plate plate number said:
SN: one of the structural steel specifications used for construction in contemporary society
490: indicates the minimum yield value unit Mpa is 490Mpa
B / C: indicates the quality level of steel plate.
SN490C structural sheet itself with high strength, high toughness, fatigue resistance, impact resistance, wear resistance, corrosion resistance, weather resistance, welding and easy processing and other high-quality performance, SN490C steel is used in the housing structure, factories, stations, and other buildings, but also used in the construction of the steel structure of the skeleton.
