Comparison of Plate Thicknesses Commonly Used for Floors, Walls and Stairs

Steel plate is a material frequently used in construction because it is strong, versatile, and easy to shape. However, its use cannot be arbitrary. The thickness of the plate must be adjusted to the function and load it will support, so that the construction results are safe and efficient.

The following is a comparison of plate thicknesses commonly used for floors, walls, and stairs:

1. Floor Plate

• Common Thickness: 8 mm – 12 mm
• Reason for Use: Floors typically support heavy loads (people, machines, or goods). Thicker plates are needed to ensure long-term strength and durability.
• Applications: Warehouses, factories, parking areas, and mezzanine floors.

2. Wall Plate

• Common Thickness: 2 mm – 6 mm
• Reason for Use: Walls do not bear significant compressive loads, so a thin plate is sufficient. The thickness is adjusted according to the needs—for example, for partitions, cladding, or wall coverings to increase strength and impact resistance.
• Applications: Iron fences, industrial wall panels, tank linings.

3. Stair Plates

• Common Thickness: 5 mm – 8 mm
• Reason for Use: Stairs must support dynamic loads (people going up and down). Therefore, they require a medium thickness to remain strong but not too heavy.
• Applications: Factory stairs, emergency building stairs, and industrial home stairs.

Conclusion

• Floor plates: Must be thick (8–12 mm) to support heavy loads.
• Wall plates: Can be thin (2–6 mm) because they only serve as cladding/partitions.
• Stair plates: Medium thickness (5–8 mm) for strength and safety.

Choosing the right thickness makes construction safer, more efficient, and more durable.
