Support & fixing for ventilation networks
What is a ventilation network?
A ventilation network is a set of interconnected components designed to ensure the circulation, renewal, and conditioning of air in a building. As an integral part of an HVAC (Heating, Ventilation, and Air Conditioning) system, it plays an essential role in maintaining a healthy and comfortable indoor environment. It ensures air renewal, thermal regulation, contaminant removal, as well as humidity and pressure control.
At SUFIX, we put our expertise at the service of building and ventilation system professionals. Our range of support and fixing products has been designed to meet your installation needs. All our products are designed with the same objectives: Guaranteeing optimal safety, ease of installation, and increased durability.

Frequently asked questions about ventilation network support
Our modular solutions adapt to all types of hydraulic and air flow networks, even in restricted spaces or atypical architectural configurations. This modularity allows great installation flexibility, essential in complex buildings.
The suitable solutions differ according to the complexity of your project and the type of installations.
Product durability varies according to environments:
Moderate environment (C3 – urban and light industrial areas)
- For Sendzimir galvanized steel with standard zinc thickness (Z275 – 275 g/m²), the lifespan can reach 10 to 15 years.
- Thicker elements or with reinforced galvanization can last up to 23-28 years.
Severe environment (C5 – heavy industrial or coastal areas)
- In these conditions, the lifespan is reduced to about 3 to 7 years for standard coatings.
- Specific solutions may be necessary to extend this lifespan.
Several factors influencing durability
Several factors can affect the durability of your galvanized steel supports:
- Zinc coating thickness: The thicker the zinc layer, the more durable the protection.
- Environmental conditions: Humidity, presence of chemicals, exposure to weather.
- Installation quality: Proper installation avoids mechanical stress that could damage the coating.
- Maintenance: Regular maintenance significantly extends the lifespan of supports.
When choosing quick suspension systems for your ventilation networks, several essential criteria must be considered to ensure an efficient, durable installation that complies with current standards:
- Load capacity
Load capacity is a fundamental criterion for ensuring installation safety:
- Maximum supported load: SUFIX quick suspension systems are designed to support loads from 35 kg to 60 kg depending on the models.
- Safety factor: Always choose a system whose load capacity is at least 30% higher than the actual load of your installation.
- Load distribution: Consider the distance between suspension points for optimal weight distribution.
- Compliance with standards and regulations
Compliance with standards is essential to guarantee the safety and legality of your installation:
- European standards: Check compliance with EN 12236 (supports for ventilation ducts) and EN 1505 (duct dimensions).
- Local regulations: Ensure the system meets the specific requirements of your region regarding construction and safety.
- Certification: Favor products certified by recognized organizations.
- Materials and corrosion resistance
The durability of the system largely depends on the materials used:
- Galvanized steel: SUFIX systems mainly use Sendzimir or electro-galvanized steel for optimal corrosion resistance.
- Installation environment: For humid or corrosive environments, opt for reinforced surface treatments.
- Material compatibility: Ensure compatibility between the suspension system materials and those of the ducts to avoid galvanic corrosion.
- Ease of installation and adjustability
Installation efficiency is a key factor in reducing labor costs:
- Tool-free system: SUFIX quick suspension systems are designed for installation without special tools, significantly reducing assembly time.
- Height adjustability: Look for systems allowing precise height adjustment (generally adjustable from 250 mm to 450 mm).
- Flexibility: Favor modular systems that easily adapt to complex configurations.
- Acoustic and vibratory performance
Reducing noise pollution is essential in HVAC installations:
- Vibratory isolation: Check the system’s ability to absorb vibrations to prevent their transmission to the building structure.
- Acoustic damping: Some SUFIX systems incorporate anti-vibration elements that reduce noise propagation.
- Compatibility with acoustic standards: Ensure the system contributes to meeting the building’s acoustic requirements.
- Specific technical considerations
Additional technical criteria can influence your choice:
- Pressure in ducts: Systems must withstand maximum network pressures (generally between 900 and 2000 Pa depending on installations).
- Air speed: Air speed in ducts (3 to 10 m/s depending on the type of premises) can influence stress on suspensions.
- Thermal expansion: Provide systems that accommodate thermal expansion of ducts.
- Durability and maintenance
The longevity of the installation depends on its initial design:
- Resistance over time: SUFIX systems are designed for increased durability, even in demanding environments.
- Ease of maintenance: Favor systems allowing easy access for inspection and maintenance.
- Possibility of evolution: Choose modular systems that can adapt to future network modifications.
- Value for money and availability
Economic considerations are also important:
- Total installation cost: Evaluate not only the cost of materials but also installation time.
- Availability of parts: Ensure the availability of components for possible extensions or repairs.
- Warranty: Check the warranty conditions offered by SUFIX for its suspension systems.
By taking these criteria into account when selecting your SUFIX quick suspension systems, you will ensure an efficient, standards-compliant, and durable installation for your ventilation networks. Don’t hesitate to consult our technical experts for personalized guidance in choosing the solution best suited to your specific project.
