In particular, the EU imports a large amount of iron ore from central and South America and Oceania, which are mainly transported by sea. The perfect port infrastructure makes the port operation cost of EU iron ore raw materials import relatively low. However, the SA514 Gr Q steel material steel transportation between EU Member States is mainly railway transportation, and the EU member states have established a very developed railway network and railway information infrastructure.

The preparation of SA514 Gr Q steel material 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 SA514 Gr Q steel material centralized control, two-layer welding process, reducing the possibility of incomplete penetration.

In year 2015, we ship 750 tons H beam to Pakistan for our old customer for building use. Because of urgent demand, the H beams are partial shipment by bulk vessel. Due to strong support of our customer, we also export many C channel steel, SA514 Gr Q steel material I beam and other profile steel to local market.
