Steel Plate

Steel Plate is an important metal raw material in international trade, typically referring to flat steel with a thickness greater than 4.75mm. It can be classified by thickness into medium-thick plate, thick plate, etc., and by application into shipbuilding plate, boiler plate, pressure vessel plate, etc. In foreign trade, steel plates are often delivered in hot-rolled (HR) or cold-rolled (CR) condition, complying with standards such as ASTM, EN, JIS, etc. Application scenarios include machinery manufacturing, construction, shipbuilding, energy industries, etc. Precautions: Material grade (e.g., Q235B, S355JR), dimensions (thickness × width × length), surface treatment (e.g., oiled, painted), tolerance range, and delivery condition must be specified; different standards have different requirements for chemical composition and mechanical properties, which must be stated in the contract. The difference from 'Steel Coil' is that steel plate is cut-to-length flat sheet, while steel coil is continuous coiled form, convenient for transportation but requires uncoiling; compared with 'Steel Strip', steel plate is usually thicker and wider. In foreign trade, trade terms such as FOB, CIF are commonly used, and attention should be paid to the unloading capacity of the destination port and steel plate packaging (e.g., bundling, wooden pallets) to prevent rust and deformation.
