Wired patterned glass is a translucent figured glass with wire inside for safety purpose which allows transmission of daylight,while obscuring visibility of object. It is manufactured by the Roll-Out-Process,whereby a roller imprints the pattern onto the glass surface.
Core Process: A special type of safety glass manufactured by embedding a pre-heated metal wire mesh (typically steel) into the glass ribbon during the rolling process, followed by annealing or tempering.
I. Core Characteristics & Functional Positioning
1. Safety & Security
①Fire Integrity: The embedded wire mesh acts as a skeleton, helping the glass maintain its integrity under high temperatures, fulfilling fire integrity requirements for building elements (some grades offer 0.5-1.5 hours resistance).
②Anti-Burglary & Anti-Through: Upon impact and breakage, glass fragments are retained by the mesh, reducing flying debris and providing significant resistance to penetration. This offers a degree of personal safety and deterrence against forced entry.
2.Aesthetic & Decorative Appeal
①The wire mesh creates a distinctive industrial, vintage, or retro visual texture.
②Mesh patterns can be customized (e.g., diamond, square, hexagonal), offering potential for branding or artistic decoration.
3.Mechanical Performance Considerations
①Due to the differing physical properties of glass and metal, its flexural strength and thermal shock resistance are generally lower than those of monolithic glass of the same thickness.
②The presence of the wire mesh complicates secondary processing (cutting and drilling are more difficult, with a high risk of chipping at edges and holes).
Functional Positioning: Traditionally used as a fire compartmentation material and shatter-resistant safety material in areas with specific fire and penetration resistance requirements. Now also widely used in interior design for its unique aesthetic.
Primary Application Fields:
①Functional Applications: Fire-rated doors and windows, escape corridor partitions, industrial skylights, warehouse high-level windows, traditional windows in schools and gymnasiums.
②Decorative Applications: Retro-style interior partitions, feature walls, furniture panels, lighting fixtures, decorative elements in commercial spaces.
II. Industry-Standard Dimensions, Thickness & Tolerances
1. Standard Thickness
The thickness of wired glass is primarily determined by its safety rating and manufacturing process.
Note: Due to the embedded mesh, thickness tolerances are generally wider than for standard float glass.
2. Common Standard Sizes
Sizes are limited by the rolling production line and mesh dimensions.
III. Standard Colors, Mesh Types & Patterns
IV. Key Considerations & Design Selection Advice
(1) Fire Certification is Paramount: For use in code-mandated fire compartmentation, it is mandatory to select fire-rated wired glass products certified by authoritative bodies (e.g., Chinese CCCF, UL, BS) and install them strictly according to their certified systems.
(2) Updated Safety Understanding: Wired glass is not a modern "safety glass" in terms of human injury prevention. While fragments are retained, the edges can remain dangerously sharp, and the entire pane may sag inward upon breakage. It should not replace tempered or laminated glass in areas where human safety is the primary concern (e.g., high-level railings).
(3) Fabrication & Installation Limits:
①On-site cutting or drilling is strictly prohibited as it causes the entire pane to crack. All fabrication must be completed at the factory.
②Use resilient setting blocks during installation and allow room for thermal expansion of the metal mesh, avoiding hard direct edge contact.
(4)Trend in Decorative Application: In modern interior design, wired glass is popular as a "translucent but not transparent" partition, creating unique light and shadow effects when combined with lighting design. Widely used in hotels, restaurants, and retail spaces.
(5)Maintenance & Cleaning: Avoid acidic or highly corrosive cleaners that could corrode the wire mesh edges. For stainless steel mesh, standard glass cleaners are suitable.
Summary
Wired glass is a unique product that combines historical functionality with contemporary decorative appeal. Its core value lies in its fire integrity and distinctive visual texture. When selecting, the primary need must be clear: For compliance with building fire codes, strictly choose certified fire-rated products. For decorative purposes, freely select patterns, colors, and mesh materials (stainless steel is recommended). 6.8mm thick, patterned glass with diamond stainless steel mesh is one of the most popular specifications in the decorative sector. It is essential to understand its mechanical limitations and adhere to its specific fabrication and installation requirements.
