Corrosion Resistance Specifications For Lightweight Energy-Saving Cable Trays
The Corrugated Base Energy-Saving Cable Tray enhances strength using structural reinforcement principles, allowing reduced plate thickness without compromising load capacity. This saves material, lowers cost, and supports energy conservation and emission reduction. The lightweight tray features reinforced ribs, with bent plates that redirect load paths to improve bending and deflection resistance. The bottom, cover, and side panels are formed using rolling and shaping equipment into lightweight steel profiles and then integrated with advanced welding techniques. Compared to traditional designs, the structure is significantly improved, providing a modern appearance while fully meeting functional requirements.
The Molded Reinforced Base Cable Tray is designed with thin-wall optimized components, reducing steel thickness while maintaining high strength. Advanced manufacturing transforms the side webs, bottom, and cover plates from flat surfaces into reinforced corrugated shapes. Multiple bending, pressing, and forming steps induce cold work hardening, significantly increasing material hardness. This design enhances thickness, bending resistance, torsional strength, and overall stability, while improving rigidity. Tests show that under rated uniform loads, deflection remains below 1/200, meeting relevant standards.
Note：
- For cable trays with a width between 100–600 mm, it is recommended to use the Energy-Saving Cable Tray with a Stamped Reinforced Bottom.
- For cable trays with a width above 600 mm, it is recommended to use the Energy-Saving Cable Tray with a Corrugated Bottom.
Organic coatings include color-coated steel plates, powder coating, painting, etc.
Our energy-saving, high-strength pressed steel cable tray is made from color-coated steel plates with organic coatings. By adopting embossed reinforcement technology and optimized thin-wall design, the tray reduces steel thickness while maintaining structural performance, meeting the requirements of energy-efficient and eco-friendly cable tray systems.
The energy-saving, high-strength pressed steel cable tray undergoes a passivation process at the steel mill, where a protective coating is applied on hot-dip galvanized cold-rolled steel plates. This process significantly enhances corrosion resistance, making it 6–8 times stronger than untreated steel. Compared with conventional steel trays, it performs exceptionally in standard salt spray and UV tests, offering a service life of over 30 years.
In terms of processing, non-destructive manufacturing technology is applied. Using German TOX riveting equipment ensures the coating remains intact. Additionally, through cold-working processes involving multiple stretching and extrusion steps, the material undergoes work hardening, greatly enhancing the load-bearing capacity of the cable tray.
Metallic inorganic coatings include hot-dip galvanizing, electro-galvanizing, and VCI (Vapor Corrosion Inhibitor) dual-metal inorganic coatings.
Introduction of VCI Dual-Metal Inorganic Coating:
The VCI dual-metal inorganic coating is developed using vapor corrosion inhibitor (VCI) technology. It uses flake zinc and flake aluminum powders as fillers, with silicate as the binder, creating an inorganic protective coating with surface conductivity.
The VCI dual-metal coating provides excellent corrosion resistance in uncovered outdoor environments and can be tightly combined with any organic coating. When applied on cable trays, it can be further overcoated with organic layers to form a composite protective system that resists acids, alkalis, and aggressive corrosive media.
As a metallic coating, the VCI layer incorporates high-performance vapor corrosion inhibitors, which slow down corrosion and ensure durability under harsh outdoor conditions. It offers strong UV resistance and anti-aging properties.
Note: When applying the VCI dual-metal coating on galvanized steel sheets, the zinc layer thickness should be ≥ 5μm. The VCI dual-metal inorganic coating should generally have a total thickness of ≥ 30μm, with a minimum local average thickness of ≥ 20μm.
Corrosion Protection Options
The corrosion protection method for cable trays should be selected based on project environmental conditions, the criticality of the trays, and the durability and cost-effectiveness of the protective treatment.
Note:
1.For outdoor applications, pre-coated steel panels are recommended to use a Polyvinylidene Fluoride (PVDF) coating.
2.In moderate or severe corrosive environments, surfaces treated with hot-dip galvanizing should undergo passivation.
3.For stainless steel cable trays in highly corrosive environments, 022CR7Ni2Mo2 is recommended; for other environments, 06CR9Ni10N or 022CR9Ni10N can be used.
4.In locations where cable tray applications need to be identified by color, color-coated steel cable trays are recommended.
Compared with conventional cable trays, the Molded Reinforced Base design saves 30–40% of material, while the Corrugated Base design can save up to 50%.
