Delivery condition: According to ASTM A20/A20M.

Heat treatment: Plate 50mm and under are normally supplied in the as-rolled condition. The plates may be ordered normalized or stress relieved, or both. Plates over 50mm in thickness will be normalized.

We can do welding, drilling, edge milling, cutting, bending, heat treatment, shot blasting for ASTM A515 GR70 steel plate, our product include different kind of vessel and boiler, such as gas holder, water pot, chemical reactor, and so on.

We have X-ray crack detection room to inspect the inner flaw of the steel work/steel structure/steel machining parts, and 5 m x 10 m large heat treatment furnace to do annealing, quenching, tempering, hardening and tempering for the steel work.

With abundant experience in this filed, we can offer customer best steel work/steel structure/steel machining parts in lowest price, if you have demands, please contact us.
