Large metal parts are rarely decided by one machine size alone. The drawing usually tells us which process should come first: flame cutting for thick plate, laser cutting for cleaner profiles, press brake work for long bends, CNC machining for tolerance features, and finishing after fit-up.
This page gives project buyers a practical view of EONE's shop-floor capacity for custom metal fabrication. The numbers below are useful planning ranges. Final feasibility is always confirmed against the drawing, material grade, tolerance, hole density, bend geometry, weld sequence, finish, and packing method.
How to use these figures: send the drawing, material, quantity, finish, and delivery requirement first. We will match the work to the right process instead of forcing every part through the same route.
Capacity at a glance
| Process | Working range | Typical use | Check before quoting |
|---|---|---|---|
| Flame cutting | Up to 21 m L x 3 m W; steel plate from about 16 mm up to 180 mm | Heavy plate blanks, large frames, base plates, welded structures | Material grade, edge allowance, heat affected zone, later machining |
| Large plate preparation | Up to 2.5 m W x 8 m L x 20 mm, depending on process route | Oversized plates, structural blanks, plates prepared for bending or welding | Flatness, handling weight, surface condition, downstream tolerance |
| Heavy press brake | 1000-ton class; up to 8 m long; steel or aluminum up to about 16 mm subject to bend geometry | Long channels, guards, formed covers, heavy bracket sections | Inside radius, flange height, bend sequence, material springback |
| Secondary press brake | 200-ton class; up to 4 m long and around 10 mm, depending on part design | Medium brackets, panels, small guards, repeat formed parts | Batch size, tool access, hole position after forming |
| Laser cutting | 20,000 W; aluminum up to about 30 mm, steel up to about 40 mm; up to 2.5 m W x 16 m L | Cleaner profiles, slots, nested parts, parts that need tighter edge control | Part size, pierce count, edge quality, nesting, quantity and material availability |
| CNC machining | Up to 2 m W x 4 m L x 1 m H | Milled faces, bored holes, slots, datum surfaces, final tolerance features | Datums, tolerance stack, fixturing, roughing allowance after cutting or welding |
Start with the process, not only the maximum size
A long table or high wattage machine does not automatically mean a part should be cut that way. For a thick structural plate, the question is often whether the edge will be welded, machined, or left as-cut. For a guard, panel, or bracket, the bend sequence may matter more than the flat blank.
That is why we prefer to review the drawing before giving a firm route. Two parts can have the same outside dimensions and require different handling if one has tight hole positions, cosmetic surfaces, deep flanges, or heavy welding after cutting.
Long and thick plate work
For large steel plates and heavy welded structures, flame cutting gives us room to handle thicker material and larger formats. It is useful for base plates, heavy brackets, equipment frames, large gussets, counterweights, and structural parts that will be welded or machined after cutting.
When the drawing needs cleaner edges, tighter profiles, or a high number of repeated details, laser cutting may be the better choice. Our laser cutting route can cover aluminum up to about 30 mm and steel up to about 40 mm, with a maximum working range up to 2.5 m W x 16 m L. The workable quantity depends on the part itself: shape, holes, nesting, pierce count, tolerance, and material stock.
Bending and forming after the blank is cut
Long plate bending is often where a fabrication plan succeeds or fails. A flat pattern can look simple until the part needs an 8 m bend, a short return flange, or a sequence that traps the part against the tooling.
For heavy forming, we can evaluate work around a 1000-ton press brake with up to 8 m length, including steel or aluminum parts around 16 mm depending on geometry. For smaller and medium formed parts, a 200-ton class route covers up to about 4 m and around 10 mm, again subject to the actual bend design.
CNC machining for tolerance features
Many fabricated parts do not need every surface machined. They need specific features controlled: a bearing hole, bolt pattern, mating face, slot, groove, or datum surface. Our large CNC machining range is up to 2 m W x 4 m L x 1 m H, which gives room for substantial weldments and heavy plate components.
For these parts, we ask for tolerance notes and datum references early. If a surface will be machined after welding, the blank should include enough machining allowance, and the welding sequence should be planned to reduce distortion.
Finishing, assembly, and repeat production
Cutting capacity is only one part of the job. Fabricated components usually move through deburring, fit-up, welding, straightening, machining, surface preparation, coating, inspection, and packing. The exact path depends on whether the part is a one-off structure, a small batch, or a repeat order.
For repeat production, we look at fixtures, handling, inspection points, and packing early. This matters for products such as brackets, buckets, machine guards, custom frames, fence and gate components, and other metal assemblies where repeatability is more important than one-time machine capacity.
What to send for a faster feasibility check
- Drawing file: PDF plus DXF, DWG, STEP, or another model file where available.
- Material: grade, thickness, temper or condition, and whether substitute material is acceptable.
- Critical tolerances: especially holes, mating faces, bend angles, flatness, and post-weld machining areas.
- Finish: raw, galvanized, painted, powder coated, blasted, machined, or customer-specified coating system.
- Quantity: prototype, small batch, or repeat production. The maximum workable quantity depends on the exact workpiece requirements.
- Use environment: indoor, outdoor, coastal, abrasive, structural, cosmetic, or equipment-mounted.
- Packing and shipping: part weight, stacking limits, pallet size, container loading, and destination constraints.
How EONE reviews a project
We do not treat a capacity list as a quote by itself. We first check whether the part should be cut, bent, welded, machined, and finished in that order, or whether a different sequence will reduce risk. Then we confirm the practical issues: material availability, fixture needs, quality checkpoints, packing, and delivery timing.
If the part is large, thick, or tolerance-sensitive, send the drawing before locking the design. Early review can prevent common problems such as holes too close to bend lines, machining allowance missing after welding, oversized parts that are difficult to coat, or packing that damages the finish.
