To provide reference opinions, and to treat customers with integrity. Consequently, we have won a lot of stable cooperated customers over the years in the international market. Our steel materials are widely used in power stations, bridges, ship manufacturing, offshore platforms, heavy machinery, oil and gas pipelines, tanks and so on fields.

We have very professional workshops for thin plates/ coils, medium and general thick plates. And also special workshop to produce thick plates that thickness is more than 300mm. we produce the steel plate include carbon and low alloy high strength steel plate, shipbuilding and offshore platform steel plate, boiler and pressure vessel steel plate, weather resistant steel plate, pipeline steel plate, alloy steel plate, automobile structure steel plate, and gas cylinder steel coil etc.

Shipbuilding steel plates have always been the key products of our company, and it is sold well in many countries and regions around the world. The thinnest certifiable thickness of our shipbuilding steel plates is up to 3mm. We cooperate with classification societies to certify the shipbuilding steel and issue EN10204 3.2 material test certificate. According to the certificate number, the customer can verify the source of the shipbuilding steel plates with the corresponding classification society near them.JIS SM400A plates

JIS SM400A plates,The characteristic of niobium in steel material is to increase the recrystallization temperature of austenite, so as to achieve the purpose of refining austenite grains. In general, the amount of niobium added in steel material is less than 0.05%, and the contribution of niobium above 0.05% to strengthening and toughening will no longer be obvious. JIS SM400A plates
