Precision Perforated Mesh: Engineered Open Area, Hole by Hole
Hebei Luojie Metal Products Co., Ltd. has expanded its CNC perforating capacity at its Anping County plant to serve filtration, acoustic, ventilation and architectural customers. Founded in 2002 and employing more than 500 people, the company produces wire mesh, fencing and perforated metal for buyers in over 50 countries, with exports accounting for 70% to 80% of sales.
Why Hole Precision Matters
In filtration and separation duty, the hole diameter and open area ratio directly determine flow rate and particle retention. In architecture, hole layout determines the visual rhythm of a facade and its shading performance. CNC punching with fixed tooling delivers consistent hole size and pitch across the full sheet, which is why designers and process engineers specify it for critical work.
Product Highlights
- Hole shapes: round, square, slotted, hexagonal, oblong and custom decorative patterns
- Hole diameter from 0.5 mm to 20 mm, open area calculated to your process requirement
- Sheet thickness 0.5 mm to 6.0 mm in carbon steel, galvanized steel, stainless steel 304 and 316, aluminum and copper
- Standard sheet sizes 1000 x 2000 mm, 1250 x 2500 mm with cut to size service
- Finishes include hot dip galvanizing, powder coating, PVDF coating and mirror polishing

Applications
Screen and filter cylinders, centrifuge baskets, grain and seed sieves, ventilation grilles, speaker covers, machine guards, acoustic panels, sunshading screens, building facades, balustrade infill and decorative interior cladding. Architects frequently combine perforated sheets with backlighting for signage and lobbies.
Custom Development
Send a drawing, a sample photo, or simply the required open area and hole pattern, and our engineering team will propose the tooling and sheet layout. Sampling before mass production is standard for architectural orders so that the client can approve the visual result.
Packing and Delivery
Sheets are interleaved with protective film, edge protected and crated for sea freight to prevent scratching and deformation. Material certificates and dimensional inspection reports are issued with each lot, and third party inspection is available on request.
