The connection between medium and heavy plates and Open slabs is that both are types of steel plates and can be used in various industrial production and manufacturing fields. So, what are the differences?
Open slab: It is a flat plate obtained by uncoiling steel coils, usually with a relatively thin thickness.
Medium and heavy plate: It refers to steel plates with a greater thickness, typically used in situations requiring higher strength.
Specifications:
Open slab: The thickness is generally between 0.5mm and 18mm, and the common widths are 1000mm, 1250mm, 1500mm, etc.
Medium and heavy plates are divided into three types: A. Medium plates with a thickness ranging from 4.5mm to 25mm. B. Heavy plates with a thickness ranging from 25mm to 100mm. C. Extra heavy plates with a thickness exceeding 100mm. Common widths are 1500mm to 2500mm, and the length can reach up to 12 meters.
Material:
Open slab: Common materials include carbon structural steels such as Q235/Q345, etc.
Applications: Widely used in construction, mechanical manufacturing, automotive and other industries, suitable for making light structural components.
Medium and heavy plate: Common materials include Q235/Q345/Q390, etc., as well as higher-strength alloy steels.
Applications: Used in bridges, ships, pressure vessels and other heavy structures.
Difference
Thickness: Open slab is thinner, while medium-thick plate is thicker.
Strength: Due to its greater thickness, medium-thick plate has higher strength.
Application: Open slab is suitable for lightweight design, while medium-thick plate is suitable for heavy-duty structures.
