SenChi - Cross Hole Perforated Metal Sheets

Typical specifications include:

• Length: custom up to 4000 mm (standard 2000 / 2440 / 3000 mm)
• Width: custom up to 1500 mm (standard 1000 / 1250 / 1500 mm)
• Thickness: 0.5 mm — 10.0 mm (common: 1.0, 1.5, 2.0, 3.0 mm)
• Materials: cold-rolled steel, hot-rolled steel, stainless steel (201 / 304 / 316), galvanized steel, aluminum alloys, copper
• Hole type: cross-shaped slots (custom arm length, arm width, spacing), mixed patterns available
• Hole size: 0.8 mm — 50 mm (custom precise to 0.1 mm)
• Open area: 5% — 70%, optimized for strength, airflow, light transmission, or acoustic needs

Cross-shaped perforations deliver a distinctive aesthetic and structural benefits: improved directional stiffness at equal open area, better design flexibility than round holes, and excellent performance for decorative facades, speaker grilles, and protective guards.

Typical problems our customers face — and how we solve them:

• Can’t find non-standard hole geometries?
  We produce true cross-shaped patterns and non-standard arrays to your exact arm length, arm width, spacing and nesting.

• Suppliers limited to round holes?
  Our CNC turret punches, progressive dies and laser systems handle intricate cross holes and mixed patterns.

• Need one provider for secondary work?
  One-stop fabrication: punching → forming → welding → finishing → assembly.

• Worry about corrosion or finish quality?
  Multiple surface options: powder coat, PVDF/fluorocarbon, anodize (aluminum), galvanize, electroplate, brushing.

• Concerned about quality and delivery?
  Sample approval, in-process inspections, and batch QA reports ensure consistent results.
