What are some fireproof cable tray companies in Brazil

Steel and stainless steel cable trays are the preferred fireproof options in Brazil, with Eletropoll being a leading local manufacturer offering high-quality, certified solutions.

Recommended Materials

Steel and stainless steel are the most commonly used fire-resistant materials for cable trays in high-risk environments such as data centers, hospitals, and high-rise buildings due to their strength, durability, and ability to withstand high temperatures without structural failure . Fiber-reinforced plastics and composites are emerging for niche applications where insulation, flexibility, and environmental resistance are required, but steel remains the standard for fire safety .

Leading Manufacturers in Brazil

Eletropoll is a prominent Brazilian manufacturer offering cable trays with ISO 9001 certification and advanced features such as hot-dip galvanization for enhanced corrosion resistance and mechanical strength . Their structural trays with 360º ferrule and Quick Joint system provide faster installation and superior durability, making them suitable for fire-sensitive installations . Other regional manufacturers may include suppliers adhering to NBR and IEC standards, ensuring compliance with local fire safety regulations .

Types of Cable Trays

• Ladder-type trays: Ideal for industrial plants and large-scale infrastructure due to structural strength, ventilation, and heat dissipation .
• Trough trays: Partially enclosed, protecting cables while allowing maintenance, suitable for commercial and residential projects .
• Channel trays: Compact and cost-effective for smaller cable bundles, often used in data centers and telecom infrastructure .

Selection Considerations

When choosing a fireproof cable tray in Brazil, consider:

• Installation environment: Humid, coastal, or chemical-exposed areas may require stainless steel for corrosion resistance .
• Load-bearing requirements: Ladder trays are preferred for heavy cable loads.
• Compliance: Ensure adherence to NBR, IEC, and ISO 9001 standards for fire safety and quality .
• Durability and maintenance: Hot-dip galvanized trays reduce long-term maintenance and improve fire resistance .

Conclusion

For fireproof applications in Brazil, stainless steel or galvanized steel cable trays from certified manufacturers like Eletropoll provide the best combination of fire resistance, durability, and compliance with local standards. Ladder-type trays are generally recommended for industrial and high-risk environments, while trough and channel trays suit commercial and smaller-scale installations .
