Standard parts for Brazilian electroplated galvanized cable trays

Electroplated galvanized cable trays in Brazil follow NBR 10476/88 standards, with zinc layers of 8–10 microns, and include complementary parts such as fasteners, supports, splices, and end caps.

Material and Galvanization Standards

Electroplated galvanized cable trays in Brazil are typically made from carbon steel and follow the NBR 10476/88 standard for internal use in areas with low corrosion risk. The zinc coating thickness is generally 8–10 microns, providing moderate corrosion protection suitable for indoor environments . Other galvanization options include:

• Hot-dip galvanized (GF): NBR 6323, zinc layer 50–60 microns, suitable for external or medium-corrosion environments .
• Pre-galvanized (PZ): NBR 7008, zinc layer 18 microns, applied via continuous hot-dip process .
• Stainless steel (AI 304/316): ASTM A480/A555, EN 10088, for high corrosion resistance in specialized applications like food, beverage, or oil & gas .

Standard Parts and Accessories

Brazilian cable tray systems include a variety of standard parts to ensure proper installation and structural integrity:

• Trays and Ladders: Straight sections, typically 3 meters long, with options for 6 meters, available in widths like 100 mm (10 cm) for medium-scale projects .
• Splice Kits and End Caps: Corner splices, 90° splice bars, and end caps for secure connections and cable protection .
• Supports and Hangers: Shelf or wall supports, center supports, and universal brackets for mounting trays to walls or struts .
• Fasteners and Quick Joints: Bolts, nuts, and quick joint systems to reduce installation time by up to 85% .
• Wire Mesh and Perforated Trays: For ventilation and heat dissipation, reducing the risk of overheating .

Manufacturing and Quality

Brazilian manufacturers like Eletropoll and Salf use hot-dip and electroplating processes with robotic welding and roll-forming techniques to ensure precision, durability, and high load capacity . Many products are ISO 9001 certified, ensuring consistent quality and compliance with national standards .

Applications

Electroplated galvanized trays are primarily used indoors in commercial, industrial, and institutional environments such as offices, hospitals, and large buildings. Hot-dip galvanized or stainless steel trays are preferred for outdoor or high-corrosion environments . In summary, Brazilian electroplated galvanized cable trays adhere to NBR 10476/88, include a full range of trays, splices, supports, and fasteners, and are manufactured to ensure durability, safety, and ease of installation.
