Will mesh cable trays have steel stamps

Wire mesh cable trays are made from steel and may include manufacturer or compliance markings, but steel stamps are not universally standard.

Materials and Manufacturing

Wire mesh cable trays are commonly manufactured from steel sheets, including pre-galvanized, hot-dip galvanized, electro-galvanized, and stainless steel (304 or 316), depending on the application and environmental conditions . These trays are engineered for durability, load-bearing capacity, and corrosion resistance, and are often used in data centers, industrial facilities, and commercial infrastructure .

Standards and Compliance

Manufacturers typically produce trays in accordance with international standards such as BS EN 61537:2023, NEMA, CENELEC EN 50173-1, and ISO/IEC 11801-1:2017 . Compliance with these standards ensures quality, structural integrity, and safety. While these standards govern material, dimensions, and load performance, they do not mandate visible steel stamps on every tray.

Steel Stamps and Markings

Some manufacturers may include identification markings, batch numbers, or certification stamps on steel components for traceability, especially in industrial or high-compliance environments . These markings can be laser-etched, stamped, or printed on the steel surface. However, not all mesh cable trays come with steel stamps, and the presence of such markings often depends on the manufacturer, the material type, and the project requirements.

Practical Considerations

• Traceability: If your project requires traceable steel for quality assurance, you should confirm with the supplier whether trays include stamped or labeled steel.
• Custom Orders: Some manufacturers offer custom stamping or labeling for large-scale or regulated installations.
• Inspection: Even without stamps, trays are usually accompanied by certification documents or material test reports to verify compliance with standards. In summary, while mesh cable trays are made from steel and may have manufacturer or compliance markings, steel stamps are not a universal feature and should be verified with the supplier if required for your project .
