CNC plasma cutting — heavy plate parts 6–80 mm with bevels
Plasma is how heavy plate becomes parts at a plate price: above 12 mm it cuts three to five times faster than laser and costs half per metre, and with a bevel head it delivers weld-ready edges. Our two HD plasma tables take full 12 m plates, so gussets, base plates, flanges, liners, crane and machine parts are cut from the plate you buy from us and shipped together.
Machines and capacity
Two high-definition plasma tables 12 000 × 3 000 mm (400 A) with true-hole technology, one with a 5-axis bevel head (±45°), one with an oxy-fuel torch for 80–150 mm; water tables for fume control; about 500 t of parts a month.
Materials and thickness
| Material | Thickness | Edge | Note |
|---|---|---|---|
| Carbon steel S235 / S355 / S690QL | 6–50 mm HD plasma; 50–80 mm conventional; 80–150 mm oxy-fuel | Ra 25–50 µm, slight bevel 1–3° | true-hole for bolt holes ≥ 1 × t |
| Wear plate AR400–500 | 6–40 mm | hardened edge ≈ 1 mm | preheat above 20 mm |
| Pressure-vessel plate P265GH–P355NH | 8–60 mm | weld-ready with bevel | HAZ removed by bevel where specified |
| Ship plate A / AH36 / DH36 | 8–50 mm | nesting from class plate | |
| Stainless 304 / 316 | 6–40 mm | oxidised edge (nitrogen / H35 gas) | laser for < 6 mm and bright edges |
| Aluminium | 6–30 mm |
Tolerances and bevels
Contour tolerance ±0.5 mm to 25 mm and ±1.0 mm to 80 mm (ISO 9013 class 3–4); kerf 2–5 mm; hole tolerance H12 with true-hole; bevel cutting V, Y, K and X preparations at 15–45° in one pass (double bevel by two passes), land 1–3 mm — what a butt weld to EN 1090 or a pressure vessel needs. Part numbers are plasma-marked or stencilled.
Typical parts
- Base plates, end plates and stiffeners for structural steel (EN 1090 EXC2–3)
- Gussets, cleats, haunch plates and splice plates
- Flanges, rings and blanks for rolling and machining
- Wear liners, chute plates and bucket parts in AR400 / 450
- Crane, machine and press frame parts to 80 mm
- Bevelled shell and head blanks for vessels and tanks
Pricing and lead time
Plasma cutting is charged per running metre by thickness (piercings included), bevels per metre extra; material at list price when we supply it. Typical rates: 2–4 USD/m for 10–20 mm, 5–9 USD/m for 30–50 mm, oxy-fuel 80 mm around 15 USD/m. Lead time 3–7 working days after drawing approval; heavy nests from stock plate within 48 h in urgent cases. Parts are stacked on pallets or bearers by drawing number.
Frequently asked questions
Plasma or laser — which should I choose?
Laser for ≤ 12 mm, tight tolerances and bright edges; plasma for 12–80 mm, bevels and large parts at lower cost per metre. We advise on receipt of the DXF.
Can you cut bevels for welding?
Yes — V, Y, K and X preparations at 15–45° with a 5-axis bevel head, weld-ready.
What tolerance does plasma give?
±0.5 mm to 25 mm and ±1.0 mm to 80 mm; bolt holes to H12 with true-hole technology.
What is the maximum thickness?
80 mm HD plasma, 150 mm with the oxy-fuel torch on the same table.
