Dominic galvanized cable tray specifications

Dominic galvanized cable trays are made of hot-dip galvanized carbon steel, designed for corrosion resistance and compliance with international standards for industrial and commercial installations.Material and Corrosion ProtectionDominic cable trays are fabricated from carbon steel and protected against corrosion through hot-dip galvanization after fabrication, in accordance with ASTM A123/A123M standards. The coating typically has a zinc weight of 460 g/m² per side or a thickness of 0.065 mm (2.55 mils), ensuring durability in outdoor and corrosive environments. Damaged areas can be repaired with compatible materials, and corrosion-inhibiting compounds are applied at junctions of dissimilar metals to prevent galvanic corrosion .Types of Cable TraysDominic galvanized cable trays are available in multiple configurations to suit different installation needs:Ladder Type: Prefabricated with two longitudinal side rails connected by transverse rungs. Standard rung spacing is 150 mm, adjustable to 225 mm or 300 mm depending on cable load and approval .Trough Type: Prefabricated with a ventilated or perforated bottom and integral or separate side rails. Suitable for widths greater than 102 mm .Channel Type: One-piece support with a solid or ventilated bottom, typically not exceeding 150 mm in width .Manufacturing and QualityDominic cable trays are produced using modern steel fabrication methods, including laser cutting, robotic bending, and welding, ensuring precision and compliance with international standards. The manufacturing facilities often include hot-dip galvanization lines for full quality control. Factories maintain ISO 9001:2015, ISO 14001:2015, and OHSAS 18001:2007 certifications, ensuring high-quality production and safety compliance .Installation ConsiderationsSuitable for outdoor and corrosive environments, including areas with high humidity or chemical exposure.PVC coatings are not used on galvanized steel trays to maintain coating integrity.Tray supports and rungs are designed to accommodate standard cable loads while minimizing structural steel requirements.Damaged or cut areas must be repaired to maintain corrosion protection .Compliance and StandardsDominic galvanized cable trays comply with NEMA VE-1 standards for ladder and trough types, ensuring proper spacing, load capacity, and ventilation. They are suitable for industrial, commercial, and utility installations where durability and corrosion resistance are critical . These specifications make Dominic galvanized cable trays a reliable choice for long-term cable management in demanding environments.
