Galvanized Steel Cable Trays vs. Stainless Steel: which one to use for each project?

Cable trays are essential elements in the cabling infrastructure of any building or industrial facility to ensure the support and protection of the cabling. Among the materials most commonly used for their manufacture are galvanized steel and stainless steel, which stand out for their unique characteristics and durability. But which one is more suitable for each type of project?

Galvanized steel: protection and resistance indoors

Galvanized steel is composed of steel coated with a layer of zinc, and is achieved through a hot-dip or cold-dip galvanizing process. This zinc coating provides moderate corrosion resistance, making galvanized steel cable trays ideal for installations in dry indoor or outdoor environments with limited exposure to moisture and corrosive chemicals. It tends to be less expensive than stainless steel, making it a popular choice for projects with tight budgets. In addition, thanks to the zinc coating, both the tray and the cables it contains remain protected from damage caused by moisture and environmental elements, ensuring a long service life.

Galvanized steel trays have a high load-bearing capacity, making them ideal for supporting large quantities of cables and heavy wiring systems. All of these features make galvanized steel cable trays suitable for a wide variety of indoor applications, such as in commercial buildings, data centers, warehouses and environments where corrosion resistance is not a critical concern.

Stainless Steel: ideal for demanding environments

Stainless steel trays are made with a steel alloy and a minimum of 10.5% chromium, which gives them excellent resistance to corrosion and rust. This property makes them especially suitable for highly corrosive environments, such as marine areas, industrial facilities, chemical plants, hospitals and anywhere corrosion resistance is essential.

Cable trays made of this material are strong and durable, minimizing the need for frequent replacements and reducing long-term costs. The smooth, non-porous surface of stainless steel makes them very easy to clean and maintain, which is why they are often widely used in sterile spaces in healthcare facilities or in the food industry. In addition, stainless steel offers excellent tensile and flexural strength, so they are highly safe for applications requiring high load capacity.

The choice between both materials will depend on the specific needs of the project, the budget and the environmental conditions in which the trays will be installed. For this reason, PUK Portacables' team of experts is responsible for advising and guiding our customers in their choice, studying the characteristics of each project and considering the specific requirements of the sector, the infrastructure and the environment. At PUK we work to guarantee the safety and efficiency of the installations we carry out, always providing the best solution: quality products with the German Made guarantee and the support of an expert team of professionals.
