A galvanized support is one of the practical products for supporting cable trays and ladders. These products, manufactured from galvanized sheet material, can be installed under the cable tray and ladder and, by attaching them to the ceiling and wall, prevent them from falling or remaining suspended. Since galvanized steel sheet is the strongest material that can be used for implementation in electrical installation projects and there is no limitation for its implementation in outdoor spaces, this product is also made of galvanized sheet material. Galvanized supports, like cable ladder clamps, support the cable ladder and tray, and their presence is essential wherever trays and ladders are installed at high elevations.
As a device that supports the cable tray and ladder, the galvanized support plays a very important role in achieving high safety and preventing the fall of cable trays and ladders. These types of products are designed with steel sheets coated with zinc, and a specific load tolerance is also considered for them. The amount of tolerable weight is completely different depending on whether these supports are used on walls or ceilings. In addition, many factors affect the strength of galvanized supports and their tolerable weight, including the density of the steel alloy, the dimensions and size of these supports, and the thickness of the galvanized steel sheet.
Given that accurately estimating the force tolerable by a galvanized support is difficult, the installation process must be carried out in such a way that there is complete confidence in the strength of these cable trays and ladders adjacent to the wall and ceiling. To be able to secure the cable trays and ladders adjacent to the wall and ceiling with supports, several supports are needed, placed at regular intervals from each other. Even if the strength of the supports is low, their resistance can be increased by adding the number of supports installed under the trays and cables. However, excessive use of these products not only does not increase safety but can also bring about exorbitant and high costs. The installation stages must be completed with proper management and in accordance with defined standards.
Inquiring about the price of galvanized supports is very important for those contractors and employers who need a cost estimate for implementing power distribution and cable support equipment. As you know, steel is known as the main component in manufacturing metal products such as cable tray and ladder supports. Therefore, it is natural that the price of these products is calculated based on the daily price of steel. The type of galvanization carried out for galvanized supports also has a great impact on their pricing. Hot-dip galvanized supports have a higher price compared to cold galvanized supports due to having a thicker zinc coating and appearance. However, in projects with high moisture sensitivity, hot-dip galvanized supports must definitely be used.
Supports actually fall into the group of cable tray and cable ladder fittings, which have the duty of supporting these parts for the professional transmission of cables and wires. In terms of installation location, these supports are divided into two categories: wall and ceiling, each with its own specific features and composed of different components.
Ceiling galvanized supports are more complex than wall supports and are composed of more parts. Ceiling supports include C-channel rails, galvanized rods, clamps, bolts and nuts, and these components. However, wall supports are made of a steel sheet bracket that has been machined in a completely engineered shape and can be installed on the wall. Therefore, these supports differ from each other both in terms of the number of parts and the installation location.
Cable trays and ladders are used to support cables and transmit them safely. The supports used for cable trays and ladders also play a supportive role and must be able to support the trays and ladders in the best possible way. Therefore, it is very important to use an appropriate number of galvanized supports needed for installation alongside the cable tray and ladder.
Depending on the length of the path, the number of supports required for cable trays and ladders varies. Sometimes you may need several supports along a single path. Depending on the dimensions of the electrical cable tray and its length in a structure, the required number of supports can vary, and attention must definitely be paid to their installation position to achieve an excellent result.
Among the variety of products available in the market for wiring in commercial, residential, and industrial buildings, attention must be paid to the quality of these parts. Galvanized supports, due to their zinc coating, have high resistance to corrosion and rust; however, their level of resistance to environmental conditions also depends on the production method and the zinc coating on these supports. In general, hot-dip galvanized supports, due to having a resistant coating applied by immersion in very hot molten zinc, can have very high resistance to corrosion. The appearance of this support will also be very smooth and attractive.
Supports with a cold galvanized coating also have a galvanized coating and demonstrate high resistance to moisture and corrosion; however, because the coating used on them is of the cold type, they will show less resistance to moisture and corrosion. Therefore, hot-dip galvanized supports can be a better choice for installation in various locations, especially environments with high humidity. However, in terms of price comparison and affordability, cold galvanized supports come out on top.
Before we introduce the various types of galvanized cable tray support designs, it is better to first become familiar with bracket components. One of the components that creates various designs in the support is the bracket. These parts are directly connected to the supports through bolt and nut connections, and through this, they can create various shapes, such as an L-shaped design, in a galvanized support.
These brackets are adjustable on the support at any height from the ceiling. Their support method is such that the cable trays are placed on the brackets attached to the support. Given the structural strength of these connections, they can practically bear the high weight of the trays and electrical cables well.
This type of support is actually among the tiered support equipment, meaning you can connect two tiered brackets to one suspended support. Therefore, in the F-shaped galvanized support design, there is the capability to use two cable trays in a tiered manner.
This type of support provides the conditions for a high volume of electrical cables to be routed and guided in a completely organized manner and with the highest level of safety along a single path by two cable trays. Of course, the number of support tiers can also be increased, in which case you can also create various E-shaped designs in your support.
The important point is that, given that these supports are connected to the ceiling from a single area, the weight increase resulting from creating different tiers on a single vertical support must not be excessive. For example, you cannot use more brackets on a single suspended support than the connector’s capacity, because maintaining the safety of the trays as well as their stability is always the priority.
This galvanized support is also abundantly used in cable tray installation projects as well as various types of cable ladders. Its structure is such that two brackets are installed on both sides of a suspended support, so the trays can be routed parallel to each other along a path.
Of course, there are also double-sided F-shaped designs that provide the conditions for you to place 4 cable trays simultaneously along a single path. Given that in such connections more than one tray is placed on the support, you must definitely ensure the firmness of the support’s connection point to the structure or ceiling.
Evaluating the hard points of the structure for installing supports is a very precise engineering measure, and specialists in this field must identify the appropriate location for installing the supports. In fact, you cannot connect the supports in every area of the ceiling, because to create a cohesive and organized cabling network, an ideal overall plan must definitely be drawn up beforehand.
This type of galvanized support mostly uses a series of complementary parts and equipment to create a U-shaped design in the support. These parts include two galvanized rods and a profile or C-channel. Its connection operation is such that the galvanized rods are attached to the profile from both sides, and then the cable tray is placed on the intended profile.
These rods, given that they are fully threaded rods, are directly connected to the ceiling and structure. This type of support is mostly used in the center of the structure and can route cable trays in a suspended manner with the highest level of safety.
Unlike various types of ceiling galvanized supports, these parts are installed on the wall. Their structural shape is designed in such a way that they can restrain the high weight of the trays and electrical cables in the wall area. These parts are used when you want to route the trays near the wall along designated paths.
In terms of structural material, wall-mounted and ceiling galvanized supports do not differ from each other. Both are made from the same metal material. Regarding the manufacturing material of these fittings, we will provide detailed explanations in the next section.
Galvanized supports are made of stainless steel material or steel alloy. As you know, this type of alloy is prone to rust and corrosion. Although it has very high resistance and strength, a series of chemical reactions occur due to moisture that can affect the metal structure. To prevent these types of chemical processes, a hot-dip galvanized coating is usually used to protect the support.
The application process is such that after complete design and shaping, the supports are coated in a molten bath containing zinc at a temperature of about 500 to 600 degrees Celsius. This protective layer can well preserve the metal structure for a long period of time exposed to environmental weather.
