A steel plate is a flat steel with a large width to thickness ratio and surface area. Steel plates are divided into two major specifications according to thickness: thin plates and thick plates.
Thin steel plate is a steel plate with a thickness between 0.2mm and 4mm produced by hot or cold rolling methods. The width of thin steel plate is between 500mm and 1400mm.
Thick steel plate is the collective name for steel plates with a thickness of 4mm or more. In practice, we generally call the steel plate with thickness less than 20mm as medium plate, the steel plate with thickness between 20mm and 60mm as thick plate, and the steel plate with thickness more than 60mm as extra thick plate.
The width of thick steel plate is from 0.6m to 3.0m. The thick plate is also divided into shipbuilding steel plate, bridge steel plate, boiler steel plate, high pressure vessel steel plate, pattern steel plate, automobile steel plate, armor steel plate and composite steel plate according to the usage.
Application:
The medium plate is mainly used in construction, machinery manufacturing, container manufacturing, shipbuilding and bridge construction, etc.
It is also used to make all kinds of containers, furnace shell, furnace plate, bridge and vehicle static steel plate, low alloy steel plate, shipbuilding plate, boiler plate, pressure vessel plate, checkered steel plate, steel plate for automobile frames, tractor parts and welding parts.
The plate is widely used in the manufacture of a variety of containers, furnace shell, furnace plate, bridge and vehicle static steel plate, low alloy steel plate, bridge plate, made like plate, boiler plate, pressure vessel plate, checkered steel plate, steel plate for automobile frames, tractor parts and welding connection component specific application.
They are commonly used in the fabrication of structural components, pressure vessels, storage tanks, bridges, machinery parts, and equipment frames.
These steel plates are known for their excellent mechanical properties, including high tensile strength, good weld-ability, and impact resistance. They can withstand heavy loads and harsh environments, making them suitable for demanding applications where strength and durability are crucial.
In summary, ordinary medium-thick steel plates are versatile and widely used materials in various industries. Their moderate thickness range and excellent mechanical properties make them ideal for structural and construction applications requiring strength, durability, and reliability.
In different countries, there are different product standards for steel plate and ordinary medium-thick steel plate. And here are some examples of the commonly used specifications and standards for ordinary medium-thick steel plate in China, the United States, the United Kingdom, and Japan:

Ordinary medium thickness steel plates are widely used in various industries. Therefore, according to the usage and material of these plates, different production standards have been established in China to meet the requirements of steel usage in various industries. Due to the limitation of web space, we only introduce here the specifications and sizes of three kinds of common steel.
