Expanded mesh for the architecture
Expanded mesh for the architecture
Introduction and Company Background
The document presents the "RES NOVA vision" catalog by the Longhi Group, a company with over 60 years of expertise in producing expanded metal mesh for architectural applications. Their FILS PROTECH Line focuses on sustainable, recyclable products powered partly by solar energy, designed for façades, ceilings, fittings, and protective solutions.
Product Range and Applications
The PROTECH line offers a variety of expanded mesh types and finishes tailored for modern architecture. Materials include hot-dip galvanized carbon steel, powder-coated steel, anodized aluminum, and chemically patinated copper. Applications cover false ceilings, façade cladding, partition walls, and decorative elements both indoors and outdoors.
Design and Aesthetic Features
- Color and Finish: Extensive color options (iridescent, matte, bright, classic, unconventional) enable unique visual effects.
- Light and Texture: The 3D mesh structure enhances reflections, transparency, and depth.
- Customization: Digital image projection on mesh surfaces allows personalized architectural communication.
Interior and Exterior Applications
Interior uses include false ceilings and partitions that create dynamic atmospheres through light diffusion. Exterior applications emphasize transparency and soft forms that avoid rigid building enclosures, enhancing visual impact and wall protection.
Project Examples and Mesh Specifications
Numerous European projects illustrate the use of specific mesh types, materials, and finishes. Examples include:
- Discoteca Bergamo (Italy): Hot-dip galvanized carbon steel mesh 200 x 100 mm, 5 x 3 mm thickness.
- Knoll International (Milan): Powder-coated pre-galvanized steel mesh COLISEUM 200 x 75 mm, 24 x 2 mm thickness.
- Mondiale de l’Automobile (Paris): Anodized aluminum mesh ACADEMY 115 x 40 mm, 20 x 1.5 mm thickness.
Environmental and Production Notes
The Longhi Group prioritizes sustainability by using recyclable materials and renewable energy sources, ensuring products meet both aesthetic and functional requirements responsibly.
Key Technical Parameters
- Mesh Sizes: Approximately 40 x 30 mm up to 400 x 140 mm.
- Material Thickness: Ranges from 1.5 mm to over 3 mm depending on design needs.
- Materials: Carbon steel (galvanized, powder-coated), aluminum (anodized, powder-coated), copper (patinated).
- Finishes: Powder coating, anodizing, chemical patination, hot-dip galvanizing.
Best Practices and Recommendations
- Utilize color and texture options to create distinctive architectural features.
- Leverage mesh transparency and light diffusion for interior and exterior designs.
- Consider digital image projection for personalized architectural elements.
- Select mesh size and thickness based on structural and aesthetic requirements.
- Adopt recyclable materials and sustainable production methods to support environmental goals.

Applications and Functional Benefits
Expanded metal mesh combines protection with aesthetics, strength with transparency. It suits industrial, commercial, tertiary, and sports environments, providing non-slip surfaces, safe walkways, parapets, and cladding solutions.
Technical Data and Identification
- Mesh dimensions (long and short way), strand width and thickness.
- Material types and finishes.
- Panel sizes and maximum sheet widths.
- Open area percentages affecting ventilation and light transmission.
- Panel thickness and weight per square meter for steel and aluminum.
Summary Table of Key Mesh Parameters
| Mesh Type | Dimensions (mm) | Strand (w x t) mm | Material | Panel Size (mm) | Open Area (%) | Weight (kg/m²) |
|---|---|---|---|---|---|---|
| AMBASCIATA | 110 x 40 (52) | 24 x 1.5 - 2 | Copper, Aluminium, Steel | Up to 2500 x 1600 | ~16% | 3.6 - 7.0 |
| SIERRA | 160 x 40 (52) | 24 x 2 | Powder coated aluminium | Not specified | Not specified | Not specified |
| COLISEUM | 200 x 75 (80) | 24 x 1.5 - 3 | Anodised aluminium, galvanized steel | Up to 2500 x 2000 | Not specified | Varies |
| FILS 21 | 45 x 15 (13.4) | 5 x 1.5 - 3 | Steel, Aluminium | Up to 3000 x 2000 | 33.3% | 8.8 - 17.5 |
| GATE | 76 x 31 (35) | 11 x 1.5 - 2 | Steel, Aluminium | Up to 2500 x 2300 | 42% | 7.8 - 10.2 |
Additional Mesh Types and Technical Data
Further mesh types such as College, Omega, Stadium, Italy, and Luna 400 are detailed with parameters including mesh size, wire thickness, weights for carbon steel and aluminum, panel sizes, thickness, and frontal open area percentages ranging from ~10% to over 60%, allowing tailored selection for structural strength, ventilation, and aesthetic transparency.
Recommendations and Usage Guidelines
- Choose mesh type based on strength, transparency, and corrosion resistance needs.
- Apply finishes like anodizing or powder coating to improve durability and appearance.
- Consider mesh dimensions and strand thickness to balance weight, ventilation, and light transmission.
- Use expanded metal mesh for safety applications such as non-slip surfaces and protective cladding.
- Prefer carbon steel for mechanical strength and aluminum for lightweight, corrosion-resistant solutions.
Conclusion
This comprehensive document serves as a key reference for architects and engineers, combining project case studies with detailed technical specifications to support informed decisions on expanded metal mesh selection for diverse architectural and industrial applications.

Stupire con la rete stirata Amaze with expanded mesh Il colore è linguaggio, emozione, stupore : andate oltre i “colori disponibili”. La scelta cromatica può imprimere la forza distintiva e caratterizzante di un progetto: colori cangianti e iridescenti, squillanti o riposanti, classici o inaspettati, luminosi o opachi. Sulla supeficie sinuosa della rete stirata, le conformazioni tridimensionali delle maglie creano riflessi, trasparenze, piccoli varchi di passaggio della luce che fanno da sfondo alla materia e ne esaltano l’elegante trama. Color is language, emotion, wonder: go beyond the “available...
