Perforated screen panels use a patterned metal plate where stiffness and repeatable geometric openings are required. Hole diameter, pitch, pattern and plate thickness are selected together.
Perforated metal screensShare a drawing, reference sample or application requirements to discuss the configuration.
The photograph shows different hole shapes in flat metal panels.
Round, square and elongated holes define different passage shapes. State the clear opening, centre-to-centre pitch and row arrangement together. The solid perimeter carries clamps, bolts or a welded frame. Keep the perforated field, mounting holes and support contact zones distinct on the drawing.
For round holes in a 60° stagger, geometric open area is 100×π/(2√3)×(d/p)². At d=3 mm and p=5 mm, this is 32.6% of the patterned field. A straight square grid with the same diameter and pitch has 28.3%. Frame overlap and support bars define the net exposed field after installation.
Perforation is followed by flattening and edge preparation. Define the flow face and contact face, then specify the finished edge condition on each. Panel thickness, unsupported span and the frame form the load-carrying assembly. Inspect opening size, pitch, pattern alignment, flatness, edge finish and fixing-hole position after forming.
| Hole pattern | Drawing dimensions | Geometric area definition |
|---|---|---|
| Round, 60° stagger | Diameter d; centre pitch p; row orientation | 100×π/(2√3)×(d/p)² |
| Round, square grid | Diameter d; equal pitch p in both axes | 100×π/4×(d/p)² |
| Square opening, square grid | Clear side b; centre pitch p | 100×(b/p)² |
| Elongated opening | Width, overall length, end shape and pitches in both directions | 100×opening area / repeating-cell area |

The perforated plate carries the fine woven layer and provides drainage. Define the cloth aperture separately from plate holes, and keep the support contact zones and peripheral seal on the assembly drawing.
Hole pattern and panel support are selected for drainage, wear and deck motion.
A robust opening pattern protects equipment while allowing a defined flow passage.
