The Vetra System by Nuova Oxidal, launched in 2000, offers a range of accessories for architectural glass installations such as structural glazing, canopies, and balustrades. These accessories enhance both the aesthetic and functional value of glass, known for its transparency and structural capabilities. Designed with precision and adhering to international standards, the Vetra System ensures high quality and durability, using premium materials like stainless steel Aisi 316 L, suitable for outdoor use.
Supports are essential for connecting bearing structures to articulated screws, available in sizes of 150 mm and 220 mm. Made from stainless steel Aisi 316 L, they can handle loads up to 800 Kgs for four-arm supports. The design accommodates various load combinations, including wind pressure and thermal expansion, with different drilling types to absorb stress and prevent pressure points that could compromise glass integrity.
Articulated screws, or rotules, connect glass to supports using a spherical joint. Made from stainless steel Aisi 316 L, they support over 300 Kgs. The choice of screws depends on the glass type and installation requirements, with options like fixed screws for specific applications such as balustrades. Proper selection and installation are crucial to prevent stress and potential glass breakage.
Glass sheets can have straight or countersunk holes, affecting tension distribution. Countersunk holes may lead to breakage under over-tension, while cylindrical holes allow sliding but can cause tension between sheets. Cylindrical holes are recommended for horizontal applications. Minimum thickness for countersunk holes is 8 mm, while cylindrical holes can start from 6 mm. All glass should be tempered or hardened and preferably undergo a Heat Soak Test (HST).
Glass fins serve as structural supports or façade reinforcements, positioned perpendicularly to the structure. Available with single or double supports, they use flat or countersunk rings and are made from stainless steel Aisi 316 L.
Nemo clamps allow the use of glass without holes, suitable for façades, stairs, and elevators, reducing costs while maintaining elegance. Clamps support up to 100 kg per clamp and can be adjusted with gaskets or adaptors.
The Light series includes stainless steel accessories for canopies, designed for aesthetic and mechanical needs. The system supports laminated glass of at least 10+10 mm thickness, handling 150 kg per attachment point, with appropriate screws and anchors essential for compliance with load guidelines.
- Types of Canopies: Single standard, single with central rod, double with cross rods, and corner canopies.
- Rod Calculation: A table provides distances from the fixing point to the wall and the height of rod fixing points, with optimal values for inclinations between 40° and 50°.
- Material Recommendations: Advised thickness includes tempered and hardened glass with specific PVB layers.
- Rod Specifications: Tension rods are supplied to measure, with adjustable inclinations up to 5°.
- Fixing Methods: Includes screws with spacers and Sirio supports for increased stability and load capacity.
- Load Capacity: Sirio A supports can handle 150 kg, suitable for high-traffic areas, while Sirio B supports handle up to 100 kg.
- Support Types: Various Sirio supports with adjustable fixing points and options for glass with or without cutouts.
- Range of Accessories: Includes self-locking nuts, special screws, silicon profiles, and spacers for installation and fixing.
- Silicon Profiles: Used for sealing between glass panels, available in different types for various applications.
The document outlines specifications for components in the Vetra System range, primarily made from stainless steel Aisi 316 L. It includes glass balustrades fixed with the Sirio system and supports with different arm configurations and hole distances, all with an electro-polished finish.
Glass sheets are to be fixed using articulated screws with spherical joints or fixed screws, both equipped with suitable gaskets. The articulated screws have a countersunk or flat head with diameters of 40 or 60 mm, type Era.
The document recommends using the Nemo clamping system for glass sheets, which does not require drilling or holes, and the Light canopies system for additional support. Both systems are designed to be flexible and adaptable to various needs.
- Sirio System: For fixing glass balustrades.
- Supports Series: Includes supports with varying arm numbers and hole distances.
- Screw Series: Articulated and fixed screws for securing glass sheets.
- Nemo System: An aluminum clamping system with an anodized silver finish.
- Light System: A canopy support system with wall and glass connections.
All components are primarily made from stainless steel Aisi 316 L, ensuring durability and resistance to corrosion.
