Cutting 100mm Steel Plate: What to Know Before You Order
100mm steel plate sits in the middle of the flame cutting range. Laser cutting covers up to 55mm, so 100mm means flame cutting. Here is what to confirm before the order starts.
Why Flame Cutting Is Used for 100mm Steel
Laser cutting at YUNCUT handles 0.5–55mm. Above that, flame cutting takes over. At 100mm, flame cutting is the established process — not a workaround.
The flame cutting range is 30–200mm. 100mm falls comfortably in the mid-range where the process is well established.
| Factor | Laser Cutting | Flame Cutting |
|---|---|---|
| Thickness range | 0.5–55mm | 30–200mm |
| Tolerance | ±0.1 ~ ±0.3 mm | ±0.5–1mm |
| Max panel | 3500×26000mm | 5500×30000mm |
| Best for | Precision parts, thin to medium plate | Thick structural plate |
Tolerances and Edge Quality at 100mm
Tolerance for flame cut 100mm plate is ±0.5–1mm. For many structural applications, this is acceptable without additional machining — confirm against your drawing and tolerance requirements at quotation stage.
Surface quality is controlled according to material, thickness and project requirements. Slag removal is standard. Flame cutting creates a heat-affected zone (HAZ) along the cut edge; its exact width depends on cutting parameters, grade, and thickness. If downstream welding or machining is planned, discuss edge condition requirements with the production team.
If your downstream process requires machining or tight fit-up, specify a machining allowance on the relevant edges at quotation stage.
Maximum Plate Size and Capacity
Maximum flame cutting panel size is 5500mm × 30000mm. For large structural components, this can avoid mid-section welds that would otherwise be needed for smaller panels.
YUNCUT operates two production facilities — Suzhou (Jiangsu Province) and Jining (Shandong Province). Scalable cutting and fabrication resources support both recurring production and project-based demand.
Beveling Review for 100mm Plate
For 100mm plate, beveling is not a standard capability assumption. Requirements above the typical 80mm beveling range are reviewed case by case. Send the target angle, groove type, root face, and affected edges for feasibility review.
If beveling is required, specify it before production so the process route can be reviewed and included in the quotation.
What to Include in Your Order
- Drawing file: DXF, DWG, PDF, or STEP
- Material grade (Q235, Q345, S355, A36, or your local standard)
- Quantity (pieces or estimated total weight)
- Bevel requirement — angle, groove type, edges affected
- Surface treatment: shot blasting Sa2.5 if coating preparation is required
- Any machining allowance requirements
Lead Time for 100mm Flame Cut Parts
Lead time is confirmed per order at quotation. Orders with beveling, large quantities, or complex geometry typically take longer than simple cut-to-size scope.
For orders with tight delivery requirements, share your drawings early. We confirm feasibility and production schedule before the order starts — not after.
