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 A572 Grade 55 HSLA Steel 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 A572 Grade 55 HSLA Steel steel transportation industry.

The preparation of A572 Grade 55 HSLA Steel galvanized steel before welding is the same as that of ordinary low-carbon steel. It is necessary to carefully handle the groove size and nearby galvanized layer. In order to achieve penetration, the groove size shall be appropriate, generally 60 ~ 65 °, with a certain gap, generally 1.5 ~ 2.5mm; in order to reduce the penetration of zinc into the weld, the galvanized layer in the groove can be removed before welding. In the practical work, the centralized beveling, no blunt edge technology for A572 Grade 55 HSLA Steel centralized control, two-layer welding process, reducing the possibility of incomplete penetration.

In 2015, we offered 230 tons 309S and 310S stainless steel A572 Grade 55 HSLA Steel plate to Vietnam fabrication company. The products are used in fabricating machine for this company. Then the customer sell the machine to south America and European market. This Vietnam company purchase more than 100 ton stainless steel from us every month.
