Concrete boxes for concrete construction - characteristics and basic benefits
Concrete boxes, also known as concrete electrical boxes or flush-mounted boxes, are accessories commonly used to secure electrical connections, i.e. various types of cables and wires. Individual types of boxes are also used to mount specific accessories (essential elements of the electrical installation) – such a solution is known as accessory boxes.
Concrete boxes are designed for pouring concrete on the construction site, which is undoubtedly their greatest advantage. As is known, concrete construction is associated with serious difficulties in conducting electrical installations - the recommended solution is therefore the use of flush-mounted boxes for mounting electrical installation elements and laying cables before pouring concrete.
Where do concrete boxes come in handy?
Electrical boxes will prove useful wherever there is a need to lay electrical installations before pouring concrete – at the stage of making reinforcements and formwork. Designing and conducting electrical connections early enough allows for significant reduction of work costs, making them faster and easier at the same time. This applies to residential construction, public utility buildings or industrial facilities.
Types of flush-mounted electrical installation boxes
In concrete construction, advanced electrical installation systems are used. The most important elements of such systems include, among others, junction boxes, lamp connection boxes, equipment boxes, equipment-junction boxes, partitions, connectors and many other devices.
For different types of electrical boxes, you can choose the right accessories. These include wall-ceiling connectors and end sleeves.
