Round Holes Aluminum Perforated Sheet HJP-1015R — real-world notes from the shop floor

Perforated aluminum has been quietly winning specs for facades, acoustic liners, and HVAC screens for years now. And, to be honest, the model that pops up again and again in RFQs is the Round Holes Aluminum Perforated Sheet HJP-1015R. Why? The 10/15 staggered round pattern hits a sweet spot: airflow, light diffusion, and weight all line up nicely. Many customers say installation is faster than they expected, probably because aluminum is forgiving and the sheets stay flat after punching when the process is dialed in.

Key specifications (field-proven)

How it’s made (and why it matters)

Process flow: alloy selection → decoiling/leveling → CNC punching (stagger 60° tool path) → flattening → edge trimming → deburring → surface prep → finish (anodize or powder) → inspection → packing. Testing typically includes thickness and temper per ASTM B209, hole size/pitch checks, burr height, flatness, coating adhesion (ASTM D3359), gloss (ASTM D523), and salt-spray for coated parts (ASTM B117 / ISO 9227). In practice, polyester powder coats achieve ≥1,000 h neutral salt spray; super-durable systems can push 2,000–3,000 h. Service life: around 15–25 years outdoors depending on finish and environment—industrial seaside sites are harsher, obviously.

Where it shines

• Building facades, sunscreens, and balcony infills (nice balance of shade and visibility).
• Acoustic liners for transit hubs and plant rooms—open area aids absorption with backing wool.
• Ventilation grilles, machine guards, and compressor screens—airflow without obvious hotspots.
• Retail fixtures and furniture—lightweight, easily brake-formed, looks clean.

Customization

Hole sizes from 3–20 mm, custom pitch, alloy/temper per load needs, cut-to-size, folded cassettes with fixing slots, and RAL-matched powder coats. For coastal projects, I usually recommend 5052-H32 plus anodize or high-build PVDF, just to sleep better at night.

Vendor snapshot (what buyers compare)

Field notes & case snippets

• Transit hub facade, Southeast Asia: Round Holes Aluminum Perforated Sheet HJP-1015R used as 3D cassettes; wind-load tested; installers praised consistent pitch in corner folds.
• Brewery plant screen: powder-coated RAL 7016; operators liked reduced visual clutter but steady airflow to chillers.
• Tech campus atrium: acoustic backing + 40% OA; reverberation time down by ≈0.4 s (client data, untreated vs treated bays).

Customer voice: “Edges came clean, no snagging on gloves” and “coating color matched our brand without touch-up.” Small things, but they add up on site.
