SIESA and Unex offer high-quality, fire-resistant cable trays manufactured in Mexico, suitable for industrial and high-risk environments.

SIESA Cable Trays

SIESA provides ladder-type cable trays made from fiberglass reinforced plastic (FRP), which are non-conductive, corrosion-resistant, and fire-retardant. These trays comply with ASTM E-84 and ASTM D-635 standards, ensuring they are self-extinguishing and have a low flame spread index of 15, making them suitable for critical environments such as industrial plants, offshore platforms, and commercial facilities. They are lightweight, UV-resistant, and designed for simplified installation, saving time and resources. SIESA trays also carry UL certification, guaranteeing safety and quality in each application (SIESA) .

Unex Cable Trays

Unex offers a wide range of perforated and solid cable trays, along with covers, junctions, and connectors. Their products are made from high-quality materials that reduce fire-related risks and provide maximum protection during installation and operation. Unex trays are adaptable, allowing reconfiguration if facility needs change, and are designed to maintain integrity under fire and environmental stress. They are widely used in industrial and automation applications, providing fire safety and durability (Unex) .

Material Considerations

For fire-resistant applications, fiberglass-reinforced plastic (FRP) is highly recommended due to its non-conductive nature, corrosion resistance, and flame-retardant properties. FRP trays are lighter than steel, easier to install, and maintain structural integrity under high temperatures, making them ideal for hospitals, data centers, and high-rise buildings where fire safety is critical (MP Husky, Apex Tray) .

Key Recommendations

• Choose FRP trays for environments requiring fire resistance, corrosion protection, and non-conductivity.
• Verify UL certification and compliance with ASTM E-84 and D-635 standards.
• Consider SIESA for ladder-type trays with UV protection and simplified installation.
• Consider Unex for perforated or solid trays with flexible configurations and high-quality fire-resistant materials. Both SIESA and Unex provide Mexican-made solutions that meet stringent fire safety and durability requirements, making them reliable choices for industrial, commercial, and high-risk installations.
