Thickness of cable tray crossarm

Cable tray crossarms typically have thicknesses ranging from 1. 6 mm to 4 mm depending on material and load requirements.

Standard Thickness Categories

Cable tray crossarms are manufactured in various thicknesses to accommodate different load levels and materials: Low to medium load galvanized steel crossarms: 2. 5 mm, 3 mm, and 4 mm are common for U-shaped or L-shaped profiles, with thickness selected based on the expected cable load. Pre-galvanized steel trays: Standard thickness is usually 1.

6 mm, with options from 0. 8 mm to 2. 0 mm available on request.

Hot-dip galvanized steel trays: Thickness can go up to 2 mm to ensure corrosion resistance and structural integrity. Stainless steel trays (AISI 304, 316, 316L): Typically available up to 1. 6 mm thickness for standard applications.

Material ConsiderationsQ235 low-carbon steel is commonly used for galvanized crossarms, produced via rolling for structural strength. Hot-rolled and cold-rolled steel may be used depending on the tray type and environmental requirements. Powder-coated or Alu-Zinc-Magnesium coated trays offer additional corrosion resistance, with thickness adjusted according to coating and load.

Standard Dimensions

Length: Crossarms generally match the width of the cable tray, with common lengths of 300 mm, 400 mm, and 500 mm. Customization: Thickness and length can often be tailored to specific project requirements, especially for heavy-duty or industrial installations.

Summary

When selecting cable tray crossarms, thickness should be chosen based on load requirements, material type, and environmental conditions. For typical galvanized steel crossarms, 2. 5 mm to 4 mm is standard, while pre-galvanized or stainless steel options may range from 1.

6 mm to 2 mm. Always verify compliance with relevant standards such as IEC 61537, NEMA VE1, or ASTM specifications for structural and safety requirements.
