Hot-rolled steel plate thickness typically ranges from 1.2 mm to 200 mm, with different thicknesses suitable for different applications. Thinner steel plates (1.2-6 mm) are often used in lightweight applications such as appliance housings and automotive parts; medium-thick plates (6-20 mm) are often used in building structures and container manufacturing; and thick plates (over 20 mm) are suitable for applications with high load-bearing requirements, such as heavy machinery and bridge construction.
Practical Tips for Thickness Selection
When selecting steel plate thickness, consider three key factors:
Load-bearing requirements: Dynamic loads require thicker plates.
Processing methods: Stamping is suitable for thinner plates, while welding processes are more adaptable to thickness.
Cost balance: While ensuring performance, choosing the right thickness can save material costs.
Thickness considerations for special applications
Some special applications have specific requirements for steel plate thickness. For example, shipbuilding, which needs to consider seawater corrosion, typically selects thicker steel plates with a corrosion margin. Pressure vessels require a minimum wall thickness calculated based on the internal pressure, while also considering safety factors and economic efficiency.
