Manual RFQ review — contact-only quotation path
Laser or flame — which cutting method fits your plate?
YUNCUT public cutting methods are Laser Cutting and Flame Cutting under Cutting Solutions. This page focuses on thick plate flame cutting; method fit for your project is confirmed during manual review.
Thinner plate & tighter edges
Laser cutting is usually suitable for thinner steel plate and cleaner edge requirements. See the laser cutting detail page or the Cutting Solutions overview.
Thick carbon steel plate
Flame cutting is typically the practical option for thick structural and heavy carbon steel plate — especially above 55mm — where laser may not be the best fit.
To recommend a method, send: thickness · material grade · drawing or specification · edge or tolerance expectation · application.
Send Requirements First Explore Cutting SolutionsWhen flame cutting makes sense for your project.
For heavy fabrication buyers who need thick plate or structural profile cutting reviewed against drawing and project requirements — not a universal solution for every cutting need.
Thick steel plate
Structural and heavy-section plate typically from 30mm upward, where flame cutting is the practical process.
Heavy fabrication parts
Base plates, frames, gussets, and large custom replacements for machinery and structural builds.
Structural steel profiles
Large plate components and heavy sections cut to drawing when panel size and thickness fit flame capability.
OEM, machinery, and project orders
Chassis sections, wear plate, and project-driven thick plate work reviewed for method fit before production.
Repeat-order discussion
Batch runs and repeat thick plate programs can be reviewed through the same manual contact path.
International export buyers
Export packing and overseas communication discussed per order — not assumed as a one-size standard.
What heavy-section buyers need confirmed early.
Thick plate flame cutting raises different questions than thin laser work. These are the most common before RFQ.
Is flame cutting right for my thick plate part?
Above 55mm, flame is typically the practical option. Between 30–55mm, method depends on tolerance — share your requirement during manual review and we recommend laser or flame before quotation scope is confirmed.
Will drawing and specification requirements be understood?
Material, thickness, geometry, edge condition, and tolerance expectations are reviewed during manual quotation review. Accurate scope confirmation depends on drawing or written specification — not assumptions from a brief message alone.
What tolerance and surface finish should I expect?
Typical flame cutting tolerance is ±0.5–1mm depending on geometry — wider than most laser bands. Cut surface is project-dependent — rougher than laser. Do not assume ±0.1mm on thick flame-cut plate. Final tolerance, edge treatment, and surface expectations are confirmed at quotation and project review — not guaranteed for every geometry without review.
Can parts be packed and prepared for export?
Packing method, protection, and export preparation are discussed against confirmed order requirements. Parts are inspected before packing where applicable.
How does flame cutting relate to Cutting Solutions?

Final cutting capability depends on material grade, thickness, plate size, geometry, tolerance and engineering review.
100mm and heavier plate requires case-by-case feasibility review.
Flame cutting is suitable for thick structural plate, but 100mm+ work is not confirmed from thickness alone. YUNCUT reviews each project manually before quotation scope is agreed.
Grade and preheat
Carbon, high-strength, and wear-resistant grades may need different preheat or process notes — confirmed during review.
Part size and holes
Plate size, hole patterns, narrow slots, edge distance, and web sections affect flame fit and sequence planning.
Heat and flatness
Thick cuts can introduce thermal deformation risk — critical dimensions and application context should be shared early.
Not one fixed band
Typical flame bands are coarser than laser. Do not assume ±0.1mm on thick flame-cut plate — confirmed at quotation.
Slag and finish
Slag removal, grinding, and weld-ready edge requirements are scoped per order — not implied in every base price.
Machining allowance
Precision-critical areas may need secondary machining, drilling, or beveling — discussed when confirmed in quotation scope.
Flame cutting tolerance is typically wider than laser — and heat can affect thick plate parts.
Final tolerance and flatness expectations are confirmed during manual drawing review and quotation. Flame cutting is a thick-plate process — not a universal precision substitute for laser work.
Flame tolerance bands
Typical flame cutting tolerance is ±0.5–1mm depending on geometry — wider than most laser bands on thinner plate.
Thermal deformation risk
Thick plate cutting may involve heat-affected zones. Part geometry, holes, narrow webs, edge distance, and cut sequence can affect flatness and dimension stability.
Share application context
Send application requirements and critical dimensions early. For precision-sensitive areas, secondary machining or machining allowance may be recommended.

Flame cutting questions before you contact us.
Do you offer laser cutting service?
Yes. Laser Cutting is a child capability under Cutting Solutions for thinner to medium plate where tighter tolerance and cleaner edges are needed. This flame cutting page focuses on thick plate work. YUNCUT is not primarily positioned as a thin-sheet laser shop; flame and heavy plate capability are the main strength here. Send thickness, grade, and application through /contact/#quote-form for method-fit review.
When should buyers choose laser cutting instead of flame cutting?
Laser cutting typically fits 0.5–55mm when tighter tolerance and cleaner edges matter. Flame cutting is usually the practical option for thick carbon steel plate — especially above 55mm. Share thickness, grade, edge or tolerance expectation, and application during manual review.
What cutting method is better for thick steel plate?
For thick carbon steel plate, flame cutting is often the practical method above 55mm. Between 30–55mm, method depends on tolerance and edge-quality needs — laser if tighter bands are required; flame if ±0.5–1mm is acceptable. Send thickness, grade, drawing, edge or tolerance expectation, and application so YUNCUT can recommend laser or flame during manual review.
Can you cut 100mm or thicker steel plate?
100mm and heavier plate can fall within the flame cutting band, but feasibility depends on material grade, plate size, part geometry, holes, heat distortion risk, edge quality needs, and downstream processing. Share basic requirements first through /contact/#quote-form — scope is confirmed during manual drawing review, not automatically from thickness alone.
How do I send drawings if there is no upload on this page?
Send basic project requirements through the contact form or email first. After YUNCUT receives your inquiry, the team follows up by email and you can send DXF, DWG, PDF, STEP, STP, or ZIP files as email attachments. There is no on-page upload system.
Can I send a simplified drawing or request an NDA first?
Yes. You may send a simplified drawing first or omit sensitive details until an NDA is arranged. For confidential heavy plate projects, contact YUNCUT before sending full drawings — use the contact form and note confidentiality in your message.
Does this website store my drawing files?
No. This page does not provide drawing upload. No drawing files are stored on this website. Send basic requirements first; share drawings by email attachment after your inquiry is open.
When is flame cutting suitable?
Flame cutting is typically suitable for thick structural plate and heavy fabrication parts. Above 55mm, flame is often the practical option. Between 30–55mm, suitability depends on tolerance — laser if you need tighter tolerance; flame if ±0.5–1mm is acceptable and the project fits thick plate work. Method fit is confirmed during manual review.
What information should I send?
Drawing or specification, material grade, thickness, quantity, part size, destination, application, and any edge, quality, packing, or secondary process needs. See the what to send section or the full quotation process page.
Can you quote without drawings?
You can start a conversation with basic project information, but accurate quotation and production scope usually require drawing or written specification review. Share what you have through /contact/#quote-form and the team will advise what else is needed.
Is flame cutting the same as Cutting Solutions?
No. Cutting Solutions is the overview for method selection. Flame Cutting is the thick-plate process option there for heavy fabrication buyers.
Can you guarantee tolerance and surface finish?
Typical flame cutting tolerance is ±0.5 ~ ±1.0 mm. Surface quality is controlled according to material, thickness and project requirements. Final tolerance, edge condition, and surface expectations depend on geometry, material, and application — confirmed during quotation and project review, not guaranteed universally without review.
Do you provide instant online pricing?
No. YUNCUT does not offer instant quote, online pricing, quote calculators, or on-page upload on this capability page. Submit project details for manual RFQ review through /contact/#quote-form.
How do European buyers coordinate?
European support is available through Aoke Industries ApS, our Denmark-based European Contact Point, for sourcing discussions and follow-up. Quotation review and production remain connected with the YUNCUT factory team.
How does heat distortion affect thick flame-cut parts?
Thick plate flame cutting can involve heat-affected zones and thermal deformation risk. Part geometry, holes, narrow webs, edge distance, and cut sequence matter. Share application requirements and critical dimensions during manual review. Precision-critical areas may need secondary machining or machining allowance — discussed when confirmed in quotation scope.
How does inspection connect with flame cutting?
Inspection scope for flame cut parts — dimensional checks, visual review, slag removal confirmation, and packing readiness — is discussed during quotation and checked before shipment where applicable. See the inspection process page for the full quality path.
