Perforated Plate Sizes and Applications
What Is a Perforated Plate?
A perforated plate is a metal sheet punched with controlled hole patterns (round, square, slot, or custom). You can use it to manage airflow, light, sound, drainage, and weight while keeping structures safe and visually consistent. In Singapore, architects, M&E teams, and fabricators specify it for façades, privacy screens, acoustic linings, plantroom doors, machine guards, and filters.
Materials and Finishes We Supply
Choose the alloy and finish that match your environment, budget, and maintenance plan.
- Stainless Steel 304 / 316 — High strength and corrosion resistance. SS316 suits coastal or chemically exposed sites. Finish options: 2B, BA, hairline, bead-blast, or mirror.
- Aluminium (Architectural Grades) — Lightweight and formable for façades and ceilings. Finish options: mill, anodised, or powder-coated.
- Galvanised / Mild Steel — Rigid and economical. Use hot-dip galvanizing or powder-coat for exterior protection.
For outdoor or coastal applications in Singapore, select SS316 or aluminium with a quality coating system to extend service life.
Patterns, Open Area, and Performance
Perforation geometry drives strength, visibility, airflow, and acoustics.
- Round Holes (Straight or 60° Stagger): Balanced strength and ventilation; ideal for HVAC and plantrooms.
- Slots / Long Holes: Higher directional airflow, good for screens and guards.
- Squares / Decorative Patterns: Strong visual rhythm for architectural features.
Open Area (OA%) indicates how much of the sheet is open space. Higher OA improves airflow and reduces weight, but it also changes rigidity and privacy.
For example, a plantroom louvre needs about 30–40% open area. The team selects 2.0 mm round holes on 3.5 mm staggered pitch in SS316. The panel meets airflow and corrosion requirements while keeping equipment out of view. If the louvre requires a support cage, pair perforated skins with round bar spacers; here’s a quick primer on mild steel round bars.
An office façade aims for 20–25% open area to soften sunlight without darkening interiors. The designer uses aluminium 2.5 mm slots with powder-coat finish to match the building palette and reduce maintenance.
Typical Sizes and Thickness
- Common Sheet Sizes: 1220 × 2440 mm; larger formats up to ~1500 × 3000 mm are available depending on pattern and alloy.
- Thickness Range: ~0.5–1.5 mm for linings and ceilings; 2.0–3.0 mm for screens; 3.0 mm+ for guards and heavy-duty use.
- Margins & Direction: You can request unperforated margins for fixing and specify pattern direction to align with your drawings.
Need cut-to-size? We can shear, laser-cut, fold, and add fixing holes so your panels arrive site-ready.
Applications
- Architectural Screens and Façades: Control glare and heat, boost privacy, and achieve a consistent visual rhythm.
- Plantroom Doors and Louvres: Protect equipment while keeping intake and exhaust efficient. For robust hinges and frames, pair perforated skins with flat-bar bracing, check practical specs in our flat bar article.
- Acoustic Panels: Combine perforated plate with absorbent backing to reduce noise in stations, plants, or workshops.
- Walkways and Guards: Improve safety and visibility around machinery and service areas. Where anti-slip and drainage are critical, metal grating may outperform perforated plate, compare options in our metal grating types and benefits.
- Retail and Interior Features: Create branded backdrops, ceilings, and balustrade infills with custom patterns.
Is perforated plate the same as perforated metal sheet?
Perforated plate is the same as perforated metal sheet. People use both terms interchangeably for metal sheets punched with holes (round, slot, square, or custom). In practice, “plate” sometimes implies a thicker gauge and “sheet” a thinner one, but you’re talking about the same product category, choose the thickness, alloy (SS304/316, aluminium, galvanised steel), hole pattern, pitch, and finish to match your project needs.
Perforated Plate Supplier Singapore
When your project needs precision, airflow, and clean aesthetics, a well-specified perforated plate outperforms ad-hoc fixes.
