Underfloor channels

Underfloor ducts are elements of hiding and securing cable lines under the surface of floors and floors in a number of types and types of rooms. The place of their location are most often large-scale facilities, spaces of administrative and office buildings. Duct and accessory systems create a duct structure that is hidden under the floor or other type of flooring, allowing for safe cabling. Regardless of the type and type of cables, they provide access to their individual critical places and easy intervention in the event of a failure. Under-floor ducts can be a place for distributing electrical installations, telecommunications cables, as well as carrying computer cabling.

Underfloor channels - variants

Under-floor ducts are usually made of two types of materials, it is PVC or galvanized sheet. Regardless of the technology of their production, they are available as a single-track, two-track or three-track assembly element. As metal systems, the channels have fixed partitions dividing the internal space into two or three sections (three-track channel). Galvanization gives them anti-corrosion resistance and allows for long-term use after flooding with a layer of the floor. They can be installed under a concrete screed, mastic asphalt and hidden in a floating screed. Various types of under-floor profiles and cable trays are commercially available. The most common are underfloor channels with a width of 190, 250, 300 and 350 millimeters. The average height ranges from 28.38 to 48 millimeters. The ducts ensure tightness in accordance with individual standards, assuming the use of appropriate accessories, such as handles and connectors, compatible with a given type of device. In new premises where underfloor cabling systems are installed, it is easy to plan and install power points, vertical elbows and duct fittings.

Under-floor channels are also available as channels and accessories made of PVC. Their mechanical strength allows for laying under-floor installations in places exposed to high pressure. They are used, among others, in car workshops and production halls. Due to the method of installation and the type of installation, there are three basic types:

  • Underfloor channels can be completely covered with concrete structure. This makes it possible to create a completely flat and resistant to external factors surface together with the installation underneath. Service access to the cabling is possible through a system of boxes, connectors and cassettes, which are part of the installation system. The under-floor boxes are height adjustable and can be adjusted within specifications to the thickness of the screed. Mounting brackets and fasteners stabilize individual elements during installation works. Under-floor installations are permanently tight, especially in the case of PVC products.

  • The second group are channels placed flush with the floor surface or other floor surface finish. The strength of the materials allows for their free arrangement depending on the needs, both on the walls and on open planes. The advantage of co-horizontal ducts is easy access to the installation at any time by means of removable surface covers.

  • Ducts for floors with an empty space below the floor level or other types of structures with platform structures. They enable free distribution of all types of cabling and connections to individual sections. Cassettes and supply points in oval or rectangular form are mounted in the outer layer of the landing and finishing surfaces. The advantage of raised systems is that there is no need to use trays between the assembly points. It is perfect for the quick construction of exhibition spaces and advertising boxes.

Technical conditions for underfloor installations

Depending on the location and methods of cleaning the floor surface, the appropriate type of underfloor installation is selected. Surfaces that require frequent and long-term contact with water, e.g. in food warehouses, fruit and food processing plants, etc., must not have points that are not protected against water and moisture. Transition places must be led tightly to a safe height, and other elements, such as connectors, must meet IP tightness standards and be properly installed. The principle of building underfloor installations is to use up to 50% of the space offered by underfloor ducts. Their size should ensure possible changes and expansion of cabling in the future.
