Customized Saddle Cabinet Technical Overview

Developed for specialized U.S. market requirements, this saddle cabinet exemplifies precision sheet metal fabrication with optimized structural and logistical features:

1. Material & Surface Treatment

• Base Material: Cold-rolled steel (SPCC/DC01) with 1.2-2.0mm thickness,
• selected for structural rigidity (tensile strength ≥270MPa) and formability
• Surface Finish: Electrostatic powder coating (RAL color matching) achieving:
  • 60-80μm coating thickness
  • Salt spray resistance ≥500h (ASTM B117)
  • Custom chromaticity ΔE ≤1.5

2. Fabrication Process

• Welded-Assembled Hybrid Structure:
  • Laser-cut components (±0.15mm dimensional accuracy)
  • Robotic welding (MIG) for main frame
  • Modular bolt-on panels (ISO 4762 hex socket screws)
• Reinforcement Design:
  • Press-formed stiffening ribs (1.5mm depth)
  • 25% increased torsional rigidity vs conventional designs

3. Logistics Optimization

• Flat-Pack Configuration:
  • 40% volume reduction vs fully welded units
  • CNC-bent interlocking flanges (90°±0.5°)
• Packaging Standard:
  • Triple-wall corrugated with EPE cushioning
  • Stacking strength ≥800kg/m² (ISTA 3A compliant)

4. Technical Compliance

• Meets ANSI/BIFMA X5.9 for commercial storage units
• UL-certified grounding continuity (≤0.1Ω resistance)

This engineering solution balances manufacturing precision (GD&T ASME Y14.5M) with cost-effective trans-Pacific shipping requirements, achieving 18% total landed cost reduction versus traditional all-welded cabinets.
