The company celebrates Hong Kong-Zhuhai-Macao Bridge Opening. In October 23th, 2018, Chinese President Xi Jinping announced the opening of the Hong Kong-Zhuhai-Macao Bridge (HZMB) in Zhuhai, South China’s Guangdong Province. The HZMB is a 55-kilometre (34 mi) bridge–tunnel system consisting of a series of A573 grade 70 structural steel plate three cable-stayed bridges, an undersea tunnel, and four artificial islands. Hong Kong-Zhuhai-Macao Bridge is the world’s longest sea-crossing bridge connecting Hong Kong, Macao, and Zhuhai—three major cities on the Pearl River Delta.
After comprehensive and professional training such as customer service, the customer service team has more strict discipline in the management of customer service team to ensure that customer service personnel respond to customers with a professional attitude. A process supervision system has been set up to let each customer supervise the process of the system with us
Specification range of available steel A573 grade 70 structural steel plate: thickness ≤ 650mm, width ≤ 4500mm, length ≤ 18000mm. Larger specifications of steel plates are also available as required. Our steel plates A573 grade 70 structural steel plate can be supplied according to Chinese standard, American Standard AISI / ASME / ASTM, Japanese JIS, German standard DIN, French NF, British BS, European EN, international ISO and other standards. Heat treatment process: controlled rolling, normalizing, tempering, normalizing plus tempering, quenching and tempering, etc.
As steel transportation belongs to the transportation of major parts, so in the process of transportation, modern logistics technology, such as centralized transportation, information technology, is a bit out of place. Based on the current situation of China's A573 grade 70 structural steel plate steel transportation industry, highway transportation is a way of transportation that many enterprises often choose. Naturally, its business volume also accounts for more than 50% of the whole A573 grade 70 structural steel plate steel transportation industry.
A573 grade 70 structural steel plate, Q345C steel plate is a kind of weldable low carbon engineering structure material, which is generally produced by continuous rolling mill. The carbon content of Q345C steel plate is less than 0.25%. The yield strength σ0.2 of Q345C steel plate is 300- 800MPa and the yield ratio is 0.65- 0.95. Q345C steel plate has excellent low temperature toughness. That is mainly owe to the solid solution of alloy elements (Mn, Si, Al, Cr, etc.), grain refinement (Nb, V, Ti, etc.), precipitation hardening (Nb, V, Ti, etc.), phase transformation strengthening (Mn, Si, Mo, etc.), and controlled rolling and controlled cooling, etc. new technologies.
Our steel products are widely used in petroleum and natural gas, chemical industry, shipbuilding, automobile manufacturing, power generation, mining, and other industries. The products A573 grade 70 structural steel plate are sold in more than 20 provinces, cities and all over the world. The company has strong technical force, complete production equipment, advanced production technology, perfect testing methods, and high-quality products.
The results of adopting two-level A573 grade 70 structural steel plate service system and implementing standardized management are mainly reflected in the formation of vigorous work style such as quick response and quick action. Our company's customer service center stipulates that employees must be accurate and quick in technical support and A573 grade 70 structural steel plate after-sales service. Through the formation of this fast, agile, vigorous style, to provide users with satisfactory service.
