Japan is a typical shipping first, and its raw materials are imported from Oceania, central and South America and other Asian countries. Most of the ASTM A588 structural steel plate steel produced is exported to China and other Asian countries, and a small amount is exported to America. Shipping is the main way of its ASTM A588 structural steel plate steel international transportation. According to the data, steel goods account for about 20% of the total sea freight in Japan. The domestic transportation of Japanese steel is mainly truck.
Laser cutting is that the horizontal laser beam emitted by the laser changes into a vertical downward laser beam through the 45° total reflector, and then focuses through the lens, forming a tiny spot at the focal point. When the spot hits the material, the material is heated to the vaporization temperature quickly, and evaporates to form a hole. With the movement of the beam on the material such as ASTM A588 structural steel plate, the auxiliary gas (carbon dioxide gas, oxygen, Nitrogen, etc.) blow away the melted slag, make the hole continuously form a very narrow width (such as about 0.1mm) cutting seam, and complete the cutting of materials.
