Standing at a new historical starting point, we adapt to the requirements of supply side A709 Gr 100 bridge steel plate structural reform, adhere to the overall strategy of "innovation driven, quality leading, quality improving and efficiency increasing, transformation and development", and constantly improve the development concept and development level with a forward-looking vision and grand vision. Now we have been ranked the International leading A709 Gr 100 bridge steel plate steel materials supplier.
ASTM A 53 A709 Gr 100 bridge steel plate covers seamless and welded steel pipe with nominal wall thickness. The surface condition is usually black and hot-dipped galvanized. ASTM A 53 A709 Gr 100 bridge steel plate is produced mainly for pressure and mechanical applications, and is also used for transport of steam, water, gas line pipes.
The five advantages of A709 Gr 100 bridge steel plate wear-resistant steel plate can reduce its own weight. The steel plate is designed according to the addition of several required alloy elements. Through the special heat treatment method of steel plate, the strength level of A709 Gr 100 bridge steel plate steel plate is improved to make it have high hardness (wear resistance) corresponding to various specifications. The result is a significant reduction in the weight of the structure.
BBN Group's first blast furnace blast dehumidification system: The project started construction on May 2 and began trial operation on August 28. All data are balanced and stable, blast furnace output indicators have improved significantly, and the daily dehydration capacity of the two blast furnaces is as high as 124 tons, with a daily increase of about 200 tons A709 Gr 100 bridge steel plate, and the blast furnace is running smoothly.
