CNC Metal Processing: The 7-Step Workflow That Makes Outdoor Tables Last 10+ Years

Wondering how CNC metal fabrication creates outdoor furniture that withstands rain, sun, and heavy use? Here’s our step-by-step process for outdoor table frames:
  1. CAD Design: Our engineers draft the table frame (e.g., 6-seat rectangular metal base) in CAD, adding precision tolerances (±0.1mm) for stability.
  2. Material Selection: We choose 6061 aluminum (lightweight, rust-proof) or 304 stainless steel (for coastal areas) and cut raw sheets to size via CNC sawing.
  3. CNC Laser Cutting: A 1000W laser cutter cuts frame components (legs, crossbars) from the sheet—clean edges, no burrs.
  4. CNC Press Bending: The press brake bends legs to 85° (slightly angled for anti-tip support) and crossbars to fit the tabletop.
  5. Welding & Deburring: Automated CNC welders join components; a deburring machine smooths all edges (safe for bare hands).
  6. Powder Coating: The frame is electrostatically coated (e.g., matte black) and cured at 180°C—creates a scratch-resistant, UV-proof finish.
  7. Quality Inspection: Each frame is checked with a CNC coordinate measuring machine (CMM) to ensure all dimensions match the CAD design.
Pro Tip: This workflow ensures our outdoor tables support 200kg per leg—perfect for commercial use (e.g., restaurant patios).
