How to Select a Steel Plate Cutting Method.
Laser or flame cutting? The right choice depends on thickness, tolerance, edge quality requirements, quantity, and final part use. This guide helps you decide — or helps you explain your requirements to us.
Laser cutting vs. flame cutting.
| Factor | Laser Cutting | Flame Cutting |
|---|---|---|
| Thickness range | 0.5–55mm | 30–200mm |
| Dimensional tolerance | ±0.1 ~ ±0.3 mm | ±0.5–1mm |
| Cut surface quality | Surface quality is controlled according to material, thickness and project requirements. | |
| Edge finish needed | Minimal — deburring usually sufficient | Slag removal, grinding recommended |
| Complex shapes | Excellent — CNC controlled | Good — suitable for simpler profiles |
| Minimum cut hole size | ≥0.4 × Material Thickness | ≥0.7 × Material Thickness (burn risk increases on thick plate) |
| Thermal distortion | Lower risk | Higher on long/narrow parts |
| Best for | Precision, thin-medium plate | Heavy structural, thick plate |
Which method is right for your parts?
When precision matters
Plate within 0.5–55mm. Tight tolerance required (±0.1–0.3mm or better on critical dims). Complex shape or hole pattern. Clean edge needed for assembly or coating without additional grinding.
When thickness is the priority
Plate above 55mm. Heavy structural application where ±0.5–1mm is acceptable. Large format panel (up to 5500×30000mm). Cost-effective for heavy plate volume.
When you are not sure
30–55mm transition zone where both methods apply. Unusual geometry or application. Tell us your thickness, tolerance, and end use — we recommend the right method.
