As we all know, in today's society, cable trays are widely used in engineering projects. They are indispensable for wiring in high-rise buildings—serving as both a support structure for cables and a means to organize their routing. In short, cable trays are a reliable assistant for cable installation.

As we all know, in today's era, cable trays are used to protect cables from external damage, so we need to pay special attention to the quality of the cable trays themselves. According to investigations, many customers find that the cable trays they purchased start to rust shortly after installation—some even rust within a few months. Could this be a quality issue with the cable trays? Below, the electrostatic powder-coated cable tray manufacturer analyzes this problem from several perspectives:

As we all know, in today's era, cable trays are quite popular in the market. With the continuous development of the economy, more and more people choose to use cable trays. So, what should you know when selecting cable trays?

First, an introduction to stainless steel cable trays: They refer to a general term for rigid structural systems where supporting cables are tightly connected, consisting of straight sections, elbows, components, supports (arms), and hangers for trays or ladders. As an installation channel used in horizontal and vertical wiring systems, cable trays are standardized, serialized, and universal cable laying equipment utilized for telecommunications cables, power cables, and pipeline cables.

Fire-resistant cable trays offer fire resistance, oil resistance, corrosion resistance, non-toxicity, and pollution-free performance. They feature convenient overall installation, a reasonable structure, a long service life, and an aesthetic appearance. Cables installed in fire-resistant cable troughs benefit from a clean environment and easy maintenance. The fireproof coating also has the characteristics of a thin film, high fire resistance, and strong adhesion.

Cable trays are available in channel-type, tray-type, ladder-type, and mesh structures. Composed of supports, arms, and installation accessories, they can be independently installed or attached to various buildings (structures) and pipe gallery supports. Featuring a simple structure, aesthetic appearance, flexible configuration, and convenient maintenance, all components require galvanization—especially for trays installed outdoors exposed to the elements. For applications near the ocean or in corrosive environments, materials must possess physical properties such as corrosion resistance, moisture resistance, strong adhesion, and high impact strength. Essentially, a cable tray is a support structure designed for supporting and routing cables.

There are various types of cable trays, which are often used as construction products in our daily lives. Long-span cable trays are one of them. They can be independently installed on various buildings and pipe gallery supports, featuring a simple structure, aesthetic appearance, easy configuration, and convenient maintenance.

Cable tray joints shall be smooth, with tight, straight seams. After installing the cover, it shall be flat without warping, and outlet positions shall be accurate. When laying in suspended ceilings, manholes shall be provided if the ceiling is inaccessible for maintenance.

The open structure of fire-resistant cable trays prevents the accumulation of water, dust, and debris, inhibiting bacterial growth for a cleaner environment. With an open design, cables achieve natural ventilation and heat dissipation—heat does not accumulate, and the temperature inside the tray remains stable. This optimizes cable performance, allowing the use of cables with smaller cross-sectional areas. Consequently, it reduces cable procurement costs, lowers energy consumption, and achieves energy savings during actual operation.

The zinc layer thickness of hot-dip galvanizing (HDG) is usually above 65 μm (455 g/m²). A zinc-iron alloy layer is formed at the bonding interface between zinc and iron, enhancing the adhesion of the zinc layer. Foreign cable tray manufacturers have conducted atmospheric exposure tests on hot-dip galvanized coatings under different environments. According to the test results, hot-dip galvanizing can meet the service life requirements of cable trays.

When it is necessary to shield the cable network from electrical interference or external influences, channel-type composite anti-corrosion shielded cable trays should be selected. In strong corrosive environments, composite epoxy resin anti-corrosion and flame-retardant cable trays shall be used. Supports and brackets should be made of the same material to extend the service life of the trays, accessories, and the entire cable tray system. It is recommended to install cover plates in dusty environments, outdoor areas, or other locations requiring protection.

The CQ1-T series ladder-type cable tray is improved and designed based on relevant domestic and foreign data. It features light weight, low cost, a unique structure, convenient installation, and excellent heat dissipation and ventilation. Suitable for laying large-diameter cables as well as high and low-voltage power cables.

Common Misconceptions in the Production of Flame-Retardant Cable Trays: Focusing only on appearance while ignoring internal performance data; high-alkali products are often well-disguised. Emphasizing thickness over intrinsic quality, or sand content over the bonding between resin and sand—while the latter is the key to quality. High-quality foreign products contain 2/3 sand with excellent bonding, as sand enhances rigidity.

Since their emergence, cable trays have developed rapidly and are now widely used, with their irreplaceable advantages. Everyone should learn how to use and install galvanized cable trays; however, regular maintenance is required during their service life. Below are some key matters to note when maintaining cable trays.

Cable trays have a wide range of applications, but they need to be selected according to the surrounding environment to ensure that their quality meets requirements during use. How should cable trays be selected? Below is a detailed introduction from cable tray manufacturers.

First, confirm whether there are high-voltage or high-temperature equipment at the designed installation location. Special attention should be paid to chemical liquids in the surrounding area to avoid potential hazards from these factors.

Recently, when chatting with friends, we found that many people are confused about the difference between cable trays and ladder trays. This confusion is not only common among friends but also among some customers.
