High weathering steel (SPA-H) is mainly used in the hot rolled state and is widely used in the container industry. Because ordinary carbon steel is very easy to corrode in the atmosphere, causing serious economic losses, the development of weathering steel has broad market prospects.
The SPA-H container includes a pair of side walls, a front end, a door end, a top plate, a floor, and an underframe structure that are connected to form the container, and is characterized in that it also includes at least two longitudinally distributed and multiple bottom frames in the underframe structure. The longitudinal beams (2) connected by the cross beams (3) together form a frame body, the floor (5) is covered and welded on the frame body, and the cross-sectional shape of the side walls is a kind of multiple groups The trapezoidal corrugated structure composed of wave crests, beveled edges and wave troughs, through the use of a new underframe structure, steel floor and corrugated plates for the side walls of the new structure, reduces the material cost of the container, reduces the weight of the box, and improves the loading And avoid the impact of the shortage of wood flooring on container production and costs. There are many types of containers. According to the type of goods loaded, there are general cargo containers, bulk containers, liquid cargo containers, reefer containers, etc.; according to manufacturing materials, there are also wooden containers, steel containers, aluminum alloy containers, FRP containers, stainless steel containers, etc.; The structure is divided into foldable containers and fixed containers.
SPA-H container steel plate is widely used for shipping containers. Since 2006, we have successfully produced SPA-H container steel plates based on the Japanese SPA-H standard for high weather resistance hot-rolled steel plates and combined with the company’s actual conditions. The production practice of more than 30,000 tons shows that the chemical composition and mechanical properties of the steel can fully meet the needs of container steel.
