In the 20s of the 19th century, engineer Henry Palmer came up with a conventional metal sheet. It was this idea that formed the basis of the creation of one of the building materials widely used in our time – corrugated board.
The main scope
Corporals are used mainly for various purposes in construction – from simple fences and non -removable formwork, to the manufacture of supporting structures. It is used as the enclosing structures of housing, industrial, trade, agricultural and warehouse facilities. The use of corrugated board is also used in the repair, reconstruction of old buildings.
Classification by purpose
Wall corrugated board – enclosing structures.
Roofing corrugated board – are also supporting structures.
Classification by physical and mechanical properties
In the height of the profile. Profiles with a profile height up to 20mm are used for fences, walls, etc. p., with a height of more than 44 mm, withstanding a significant distributed and transit load – is used as a roof.
The form of the profile distinguishes such types of corrugated board: wave -shaped corrugation imitating slate and trapezoidal.
According to the thickness of the sheet used for manufacture (from 0.4 mm to 1.5 mm or more).
By width of the profile.
Classification by protective and decorative properties.
Depending on the requirements for the duration of operation, the decorative and aesthetic requests of the modern design of the structures of corrugated board can be made from various materials and have a different coating:
Steel sheet without coating (practically not used due to low corrosion resistance).
The steel sheet is galvanized
Steel sheet galvanized with polymer coating. Polymer coating can be made of – polyvinyl chloride, acrylic, polyester, polyurethane, etc.
Advantages of use
Ease of installation, high operational qualities, reliable protection against external influences allow the use of corrugated board in the construction of almost any objects. The ease of these materials leads to a decrease in the total weight and cost of the structure. All these facts are made by corrugated board competitive compared to any traditional enclosing constructions.
And taking into account the wide color scheme of modern polymer coatings, corrugated board can be used in the construction of any architectural structures, regardless of installation conditions, difficulties of operation, construction sites and aesthetic requests of the customer.
