Types of corrugated board - what unites them?
Profiled sheeting is called cold-formed steel sheets with longitudinal stiffeners( corrugations) of a trapezoidal shape. Significantly less corrugations are given other outlines. Depending on its further use, raw materials for the production of corrugated board are either simply galvanized steel, or it, but with a polymer coating.
The bearing capacity of the sheet is directly proportional to the height of the stiffener. Due to the possibility of making sheets of varying degrees of resistance to mechanical influences and the influence of the environment, the choice of corrugated board and the scope of its application is extremely wide. The service life of a sheet of galvanized steel is more than 35 years, and with a polymer coating - over 45.
Types of corrugated board and their application
Profiled sheeting is installed in both horizontal and vertical directions and is used for both internal and external finishing of structures. For decorative wall covering, for fences and gates, for ceiling coverings, sheets with corrugations below 20 mm are usually used.
A large height of the stiffener is necessary when using corrugated board as a carrier element. In general, this material is widely used in industrial and residential construction for the cladding of warehouses, hangars, shopping centers, the construction of fences and the installation of roofing. It is also used in the construction of non-removable formwork.
Types of corrugated board are distinguished for their functional purpose. So, roofing is used as a coating for roofs of buildings for various purposes. This is due to its external attractiveness and low sensitivity to the effects of atmospheric phenomena.
Not the least role in this is the ease of its installation and transportation, which led to its use also in the arrangement of various types of fences and gates.
Wall corrugated board is used in the construction of walls and partitions. Its profile can have additional sewage channels, locks of fastenings, etc. The carrier is necessary for the erection of strong structures and ceilings, and also as a fixed formwork for the construction of walls and foundations. Decorative is used as a facing material.
The choice of corrugated board - where to find clues?
To determine how to choose the corrugated board for its intended purpose, its indexing( marking) helps:
- C - the height of the corrugation is 8-44 mm. For example, the name "corrugated board C44" indicates that the height of the corrugation is 44 mm. It is used for making fences, partitions, gates and gates;
- H - the height of the corrugation is more than 44 mm. Serves to create a permanent formwork, ceilings, canopies, canopies. It differs by its strengthened bearing capacity. Very good for repair and insulation of the old roof;
- НС - the height of the corrugation is 35-44 mm. It is used for the equipment of wall fences( stalls, stalls, cottages, petrol stations, hangars, garages, etc.) and decking.
However, varieties of corrugated board are not limited to just sheets with different heights of the corrugation, because, depending on the field of application, they can be with different coatings or even without them. Let's try to figure out what kind of corrugated board depends on the coating:
- with paintwork surface, often used for interior decoration, is applicable in private construction;
- with a polymer coating, it is used as a roofing material;
- without coating, used for formwork, when erecting structural elements of structures;
- double-sided, the protective layer is applied from two sides.
Also profiled on the contour of the profile and its height is divided into symmetrical and asymmetrical. Now, knowing what type of corrugated board is applicable in this or that situation, it will not be difficult to find it in accordance with the need.
