Why QG800

Five principles. One platform.

QG800 cutting a large steel tube inside its fully enclosed cell

SAFETY

Stationary Material. Safer Operations.

The workpiece stays still while the cutting head moves around it. No swinging heavy sections, no uncontrolled drops.

PRODUCTIVITY

Continuous Cutting. Maximum Throughput.

Continuous, high-speed cutting across lengths, geometries and contours, with fewer interruptions and less handling between parts.

Rendered cut ends of heavy steel sections the QG800 handles, to one scale: Ø800 round, 800 WB, 600 square, 610 UB, 400 WC, 310 UC, 380 PFC, 200 EA

CAPABILITY

Built for Heavy Steel. Engineered Without Compromise.

Capacity: up to 4 tonnes per 12 m workpiece
Profile size: 80–800 mm circumscribed diameter
Profiles: CHS, RHS, SHS, UB, UC, PFC, angles and more
Length: 12 m in / 12 m out, longer lengths to order

FLEXIBILITY

One Platform. Limitless Possibilities.

Different profiles, lengths and contours on one machine, from one-off custom parts to high-volume runs.

MAINTAINABILITY

Less Complexity. More Reliability.

A simplified mechanical design with fewer motors, servo drives and moving parts means less maintenance and easier servicing.

Heavy-duty laser profile cutting

A Decade of Innovation.
A New Era of Steel Processing.

One machine for CHS, RHS, SHS, UB, UC, PFC and angles: 12 m in, 12 m out, up to 4 tonnes per workpiece, with the material held still while the cutting head does the moving.

More than ten years of engineering refinement have gone into the QG800: heavy-duty capacity, a simplified mechanical design, and a 12 m in / 12 m out configuration that extends to customised long-length lines.

Australian standards

The manufacturer's documentation cites Chinese national standards. We have listed the corresponding Australian standards below, with notes where they are not a one-to-one match.

[1] Hollow-section shape tolerances: AS/NZS 1163:2016 Cold-formed structural steel hollow sections: Replaces the Chinese national standard for cold-formed hollow sections cited in the manufacturer's documentation. AS/NZS 1163 allows straightness of 0.15% of length, which is looser than this machine's own 1 mm/m bow and 0.02% twist limits; order material to the tighter machine limits.
[2] Tube outside-diameter tolerance: AS/NZS 1163:2016 (no direct equivalent): The manufacturer's figure (±0.5% of OD, min. 0.2 mm) comes from a Chinese seamless-tube tolerance class with no Australian equivalent. AS/NZS 1163 permits ±1% (min. 0.5 mm), so specify the tighter tolerance when ordering.
[3] Structural section sizes: AS/NZS 3679.1 hot-rolled sections (UB, UC, TFB, PFC, EA, UA), AS/NZS 3679.2 welded sections (WB, WC) and AS/NZS 1163 hollow sections: The manufacturer quotes the range in Chinese section sizes. We have restated it as the Australian sections that fall inside the same depth, flange-width and leg-length limits. Welded sections are to AS/NZS 3679.2. Confirm fit on unusual sections with us.
[4] Ingress protection (IP54): AS 60529 Degrees of protection provided by enclosures (IP Code): AS 60529 is based on IEC 60529, so the IP54 rating carries over directly.
[5] Electrical supply: AS 60038 standard voltages; AS/NZS 3000 Wiring Rules: Australian three-phase supply is commonly rated 415 V, 50 Hz (400 V nominal under AS 60038, with a tolerance band that covers 415 V). The machine's internal input is 380 V, so a 200 kVA voltage stabiliser is supplied as standard to match the two. Connection and earthing must be carried out by a licensed electrician to AS/NZS 3000.
[6] Floor slab concrete: AS 1379 Specification and supply of concrete (N25): The manufacturer specifies Chinese grade C25 (25 MPa cube strength). N25 (25 MPa cylinder strength) is the nearest standard Australian grade and meets or exceeds it.
