All about C9 corrugated board

Profiled iron products are widely used in various areas of construction, as well as in the construction of residential premises. C9 corrugated board is a profile for walls, but it can also be used as a product for installing roofs.

C9 profiled sheet can have two types of coating - zinc and decorative polymer. Painted corrugated board C9 is available for sale in all kinds of shades. All of them are indicated in RAL - the system of accepted colors. The polymer coating can be applied on one or two sides at once. In this case, the surface without painting is often covered with an additional layer of transparent enamel.

The C9 is manufactured from cold rolled zinc plated steel. This is exactly what is spelled out in GOST R 52246-2004.

The C9 product is used for:

• arrangement of a roof with a slope of more than 15 °, when there is a solid lathing or a step from 0.3 m to 0.5 m, but the angle increases to 30 °;
• design of prefabricated houses and structures, pavilions for trade, car garages, warehouse premises;
• creation of all kinds of frame-type structures;
• erection of panel systems, from which fences are made, including fences;
• insulation of wall partitions and the buildings themselves;
• reconstruction of structures;
• construction of sandwich panels at an industrial level;
• designs of false ceilings of any configuration.

A profile sheet is steel in a roll, the plane of which, after processing on special machines, has a wavy or corrugated shape. The task of this operation is to increase the longitudinal rigidity of the structure. Thanks to this, even a small thickness allows the use of the material in construction, especially where dynamic and static loads occur.

Product marking is necessary to indicate the main properties of the described profile. The dimensions are also indicated there, including the width.

For example, professional sheet C-9-1140-0.7 is deciphered as follows:

• the first letter indicates the main purpose of the product, in our case it is a wall profile;
• number 9 means the height of the bent profile;
• the next digit indicates the width;
• at the end, the thickness of the sheet material is prescribed.

The described product can be of 2 types.

• Galvanized. It is characterized by the presence of an anti-corrosion coating on the surface. Manufactured from sheet steel.
• Colored. In this version, a primer is first applied, then a zinc coating and only after that a decorative layer. The latter can be polyester, polymer textured coating or Pural.

The protective layer can significantly increase the life of the product. Under normal conditions, the service life of a profile of this class is 30 years. Due to its low weight, the material is widely used in the construction industry. It can be used for non-removable formwork as well as frame systems.

• Before using the corrugated board as a material for the roof, you will need to correctly make the crate.
• A vapor barrier must be installed, but a gap is left for ventilation. Then the lathing is installed and then the building material.
• Since the lathing is made of timber, additional processing from moisture and mold will be required. A building antiseptic is suitable for this.
• When using the C9 profiled sheet, it is necessary to take into account its features. As a material for construction, it is one of the most affordable options for roofing and walls today.

The minimum weight makes it easy to transport the sheets for roofing. Just two people are enough to create an attractive roof for any architecture.

It is the long service life and reasonable price that allowed increasing consumer demand for the described product. In addition, manufacturers offer a wide range of color palettes.
