Service Overview
High-Precision Fiber Laser Cutting & Metal Bending Solutions
Qiaodi Steel provides turnkey sheet metal laser cutting and CNC bending services engineered to meet exact industrial specifications. Operating from Wuxi—China’s primary industrial manufacturing and metal distribution hub—we combine high-power fiber laser technology with advanced multi-axis CNC press brakes to process stainless steel, carbon steel, aluminum, and specialized alloys.
From rapid prototyping and low-volume custom parts to large-scale structural manufacturing, our engineering team works directly with your DXF, DWG, STP, STEP, and PDF files. We provide integrated nested laser cutting and multi-bend forming to maximize material yield, minimize production lead time, and lower overall costs.
Core Fabrication Capabilities
- 01 / High-Power Fiber Laser Cutting
- Capabilities: Clean, burr-free edge cuts with tight tolerances and minimal Heat-Affected Zone (HAZ). Capable of cutting intricate contours, complex hole patterns, and heavy-plate structural shapes.
- Advantages: High cutting speed, smooth vertical cut surfaces, no tooling costs, and maximum sheet yield through CAD nesting optimization.
- 02 / Precision Multi-Axis CNC Bending
- Capabilities: CNC press brakes with hydraulic crowning and laser angle-measuring systems for accurate bending angles, repeatable radii, and complex multi-bend profiles.
- Advantages: Precise spring-back compensation, consistent angle accuracy across long workpieces, and versatile tooling for channel, box, and custom enclosure geometries.

Quality Control & Dimensional Verification
- 100% Contour & Flatness Check: Laser-cut edges and hole diameters are verified using digital calipers and optical measuring tools to ensure zero burrs and precise hole pitches.
- Bend Angle & Radius Inspection: CNC-bent parts are checked with digital angle gauges, radius gauges, and checking fixtures to ensure exact fit-up during final assembly.
- Material Traceability: All raw metal sheets and plates are verified via PMI spectrometers and backed by EN 10204 3.1 Mill Test Certificates (MTC).
Secondary Finishing & Value-Added Services
- Countersinking & Tapping: Precision thread tapping, countersinking, and press-nut (PEM nut) installation on cut/bent sheet metal parts.
- Deburring & Edge Rounding: Automated deburring and edge rounding to remove sharp edges for safe handling and proper coating adhesion.
- Surface Finishing: Powder coating, sandblasting, passivation, electro-polishing, and zinc plating.
