Construction of Mexican Tray-Type Cable Trays

Mexican tray-type cable trays, such as Tecnotray's mesh trays, are lightweight, open-structure supports designed for low-load cable management, made from galvanized or stainless steel and compliant with national and international standards.Materials and ConstructionMexican tray-type cable trays are typically constructed from electro-welded steel wires or metal sheets, forming a mesh or basket-like structure that allows ventilation and easy cable access . Common materials include:Electrolytic Galvanized Steel: Suitable for moderate environmental conditions, with coating thicknesses of 5–12 microns .Hot-Dip Galvanized Steel: Recommended for severe environmental exposure, with a minimum thickness of 27 microns .Stainless Steel (ANSI 304): Provides excellent corrosion resistance for highly aggressive environments, such as chemical, food, or saline industries .Aluminum: Lightweight and corrosion-resistant, often used for low-voltage or telecommunication cables . The trays are designed to support voice, data, network, power, and sound cabling, with open mesh construction promoting ventilation and heat dissipation while preventing moisture accumulation .Design FeaturesOpen Ladder or Mesh Structure: Two longitudinal side rails connected by cross members or welded mesh, allowing easy cable installation and maintenance .Load Capacity: Typically classified as low-load supports, suitable for office ceilings, IT rooms, shelters, and indoor cabinets .Ventilation: Open design ensures airflow around cables, reducing overheating risks .Accessibility: Cables can be installed or removed from the top or bottom, facilitating maintenance and future expansion .Installation ConsiderationsIndoor Use: Recommended for areas with minimal dust, splashes, or mechanical damage .Not for Walking Surfaces: These trays should not be used as corridors, ladders, or elevator shafts .Support and Fastening: Modern systems include straight sections, bends, joints, brackets, and fastening accessories to adapt to complex routing .Compliance: Products are certified by ANCE, LAPEM, PEMEX, and UL, ensuring adherence to Mexican and international standards .AdvantagesLightweight and Flexible: Easy to handle and install in confined spaces.Corrosion Resistance: Choice of galvanization or stainless steel ensures durability in various environments.Scalability: Supports future cable additions without major modifications.Cost-Effective Maintenance: Open design allows quick inspection and cable replacement . Mexican tray-type cable trays are widely used in commercial buildings, industrial facilities, and data centers, providing a reliable, ventilated, and code-compliant solution for organized cable management .
