1. Manufacturing Process
Hot-rolled checkered plate
High-temperature rolling: After heating the steel, the steel is passed through rollers to directly extrude the pattern, forming an iron oxide layer (black-brown) on the surface.
No galvanizing required; corrosion resistance depends on subsequent painting.
Galvanized checkered plate
Cold-rolled and hot-dip galvanized: First, the plate is cold-rolled into a flat sheet, then immersed in a zinc bath to form a silvery-white zinc layer.
Double-sided pattern (one side raised, the other concave), zinc layer thickness 80-275g/m².
2. Performance Comparison
| Performance | Hot rolled checkered plate | Galvanized checkered plate |
|---|---|---|
| Corrosion resistance | Easy to rust, need painting protection | Strong corrosion resistance (zinc layer protection) |
| Anti-slip | Deep pattern, good anti-slip effect | The pattern is shallow and the anti-slip performance is slightly weaker |
| Strength | High strength, suitable for load-bearing | Better toughness, suitable for complex stress environments |
| Processing difficulty | Easy to cut and weld | Special equipment is required to avoid damage to the zinc layer |
3. Applications
Hot-rolled checkered plate for load-bearing building structures, machinery manufacturing, and anti-slip flooring (workshops, staircases).
Galvanized checkered plate for architectural decoration, vehicle manufacturing, outdoor billboards, and ship decks (where corrosion protection is required).
