Cold-rolled stainless sheet is formed into a tray with regular openings, raised sides, and a smooth exposed surface. The openings release heat and leave cables visible for inspection, while the side walls keep the route organized. Perforated Cable Tray Types made from 304 stainless steel serve ordinary workshops and urban outdoor routes; 316L addresses chloride-bearing marine, chemical, pharmaceutical, and medical environments. Brushed, mirror-polished, and passivated finishes provide different surface conditions for cleaning and appearance. Without a separate anti-rust paint film, normal care centers on surface cleaning and inspection during routine maintenance.

Product Advantages
• The 18% chromium and 8% nickel composition of 304 supports stable service in ordinary industrial air and neutral salt-spray conditions without a painted anti-rust layer, reducing coating upkeep.
• Molybdenum-bearing 316L improves suitability for chloride exposure, while its low carbon limit helps control intergranular-corrosion concerns in marine, chemical, pharmaceutical, and medical settings.
• Accurate cold rolling maintains dimensional tolerances, and brushed, mirror-polished, or passivated finishes simplify cleaning and visual checks in hygiene-sensitive rooms.
Main Applications
• Perforated Cable Tray Types carry cable routes on marine platforms, in chemical areas, pharmaceutical clean rooms, hospitals, ordinary urban outdoor installations, and other corrosion-sensitive facilities worldwide.
• Stainless construction also suits rail-signal routes exposed to wide seasonal temperature changes. Grade and finish can follow corrosion level, sanitation needs, dimensions, load duty, support span, and cleaning requirements.
FAQ
Q: Which grade suits salt-bearing or coastal air?
A: 316L is the available grade because it adds molybdenum and keeps carbon at no more than 0.03%.
Q: Is repainting part of normal surface care?
A: No. The stainless surface has no separate anti-rust paint layer, so routine care focuses on cleaning and inspection.
Q: What should be compared when ordering Perforated Cable Tray Types?
A: Compare grade, finish, dimensions, load duty, support span, hygiene requirements, and corrosion exposure.
