What Are the Classifications of Sanhe Steel Plates?

Sanhe plate refers to flat steel products featuring a large surface area and a high width-to-thickness ratio. By thickness, steel plates fall into two main categories: thin plates and heavy plates.

Thin steel plates of Sanhe Steel are manufactured via hot rolling or cold rolling, with thickness ranging from 0.2 mm to 4 mm and width between 500 mm and 1400 mm. They are rolled from different steel billets to suit diverse application scenarios. Common materials include ordinary carbon steel, high-quality carbon steel, alloy structural steel, carbon tool steel, stainless steel, spring steel and electrical silicon steel. Thin plates are widely applied in automotive, aerospace, enamel, electrical and machinery industries. Apart from raw rolled sheets delivered directly, there are also pickled, galvanized and tin-plated thin steel plates.

Checker plate, also known as patterned steel plate, has raised diamond or linear ridges on its surface. The patterns offer anti-slip performance and decorative effects, making the plates ideal for factory flooring, stair treads and workshop staircases.

Hot rolling is a forming process carried out above the metal’s recrystallization temperature. Ferrous steel materials are generally rolled at temperatures between 900°C and 1200°C.
