Perforation is developed around hole geometry, pitch, open area and material, using more than 15,000 patterns and custom layouts. Advanced perforation can use holes at or below sheet thickness; feasible combinations depend on the material and pattern.

Pattern choice

More than 15,000 perforation patterns, plus custom layouts

Advanced perforation

Holes can equal or be smaller than sheet thickness; feasible combinations depend on material and pattern

Round-hole layouts

Triangular 60°, staggered, diagonal 45° and rectangular layouts; open, half-closed and closed ends, with special tooling for closed ends

Slot patterns

LR rounded ends and LC square ends; staggered, straight, 45°, herringbone and cross layouts

Feed-screen pattern examples

Separate examples (pattern: hole / open area / sheet thickness): R0.8T1.5: 0.80 mm / 25.8% / 1.00 mm; R1T2: 1.00 mm / 23.0% / 1.25 mm; R1T1.75: 1.00 mm / 30.0% / 1.25 mm; R1.25T2: 1.25 mm / 35.4% / 1.25 mm; R2T3: 2.00 mm / 40.3% / 2.50 mm; R3T4: 3.00 mm / 51.0% / 3.00 mm; R3.5T4.7: 3.50 mm / 50.3% / 3.00 mm; R4T5.4: 4.00 mm / 49.8% / 3.00 mm. These are distinct configurations.
