The production of corrugated board is the formation of a profile from a sheet of galvanized steel. Production involves the use of coated steel, which gives the material decorative qualities. Production is based on the method of cold rolling sheets on special machines that turn the sheet into corrugated corrugated board. Using special aggregate equipment, sheet geometry is formed. The main equipment involved in the production of corrugated board is: rolling mill, unwinder, receiving device, automatic control system, scissors. If you need a professional flooring, for the construction of a temporary fence it is better to purchase corrugated board with aluzinc coating. Galvanized corrugated board c8 1150 — best option for your site.
Decking is a profiled sheet made of quality steel with a colored polymer coating or galvanized steel. It is produced by cold rolling, and then profiled to give excellent rigidity. The material is used in the following areas: construction of warehouses, hangars, fences, fences, temporary structures, ceilings, etc.
Decking, for example, in comparison with metal tile is easier to install as a roofing material.

Material marking
The scope of each type of corrugated board is reflected in its marking. There are such brands of corrugated board:
- H - supporting, roofing sheeting (H60, H75, H114) has a large profile height, high rigidity and resistance to heavy loads. It is used for floors, as well as fixed formwork in construction.
- C - wall, corrugated fence (C8, C20, C21) is also used to install partitions and facade cladding.
- NS - universal, professional flooring for roofing, fence, ceilings (NS35, HC44).
Decking is marked so that the title displays the height and width of the profile, its purpose and thickness of the metal. For example, C20-1150-0.5 means: C20 - wall profile 20 mm high, 1150 mm wide, metal thickness 0.5 mm. Decking produce measured length.
There are many different classifications of corrugated board, consider the main ones:
- by type and height distinguish between symmetrical and asymmetric corrugated board;
- in shape: sinusoidal, trapezoidal, rounded;
- by coating: varnished and galvanized.
Roofing Decking
According to SNP, corrugated roofing is recommended to be made with aluminum or zinc coating. Under the corrugated board, wooden bars and metal runs are used as the base. According to building standards, the bearing capacity of the base is calculated taking into account the future load and wind force. According to SNiP, corrugated board is suitable for those buildings where the roof slope does not exceed 12 meters. For roofing, only material with a profile height of 20, 35 mm or more is used. This is stipulated by the need to withstand significant snow loads.
The dimensions of the profiled sheet for the roof are ordered depending on the length of the roof slope. The sheets are mounted on a crate impregnated with an antiseptic or on steel girders. For fastening, you can use self-tapping screws.
Roofing profiled sheet, the dimensions of which can be standard, acquire depending on the length of the ramp. Over the extreme points of the slope, the material should protrude 400 mm. Depending on the manufacturer, the sheet width varies from 980 to 1850 mm.It should be noted that the useful sheet width is on average 40-80 mm less.
The dimensions of corrugated roofing are often in the range of 930 - 1160 mm of useful width. Roofing decking consists of:
- basics - steel sheet;
- zinc coating;
- anticorrosive phosphate layer;
- primers;
- external polymer coating;
- protective inner varnish.
Each of these layers performs its function, and with proper installation, such material will last for many years.
For the construction of the roof, a material is often used in which the profile height is more than 35 mm.
For roof installation, profiled sheets with a corrugation height of 44 mm are often used. It is also envisaged to use aprons made of galvanized sheets to adjoin the roof sheet to the wall.
Roof decking, sizes which can be ordered individually, has a high bearing capacity. It can withstand heavy loads in the form of rain, hail, snow. Thanks to its flexibility, it can be used for arranging roofs of any configuration. Decking weight m2 may be from 5.13 kg to 11.01 kg.
During the installation of the roof, many people have a question: how to cut corrugated board? There are several options. Firstly, you can use scissors, while the edges will be even and clean; secondly, a grinder, it will be easier to work with it, but there is a chance to burn the edges; thirdly, a metal file or an electric jigsaw. If you purchased a professional flooring with a polymer coating, then the use of a grinder is strictly prohibited.
The colors of corrugated roofing are quite diverse, it all depends on the manufacturer. Usually it is about 15 colors, among which it is easy to choose the one that is ideal for the appearance of your home.
The advantages of corrugated board
This material has a wide range of advantages in comparison with similar types of flooring. Often it is used in the construction of facing and roofing material. Decking is made of galvanized steel and coated with a special colored polymer coating. It is also used for the construction of various fences. Due to the ease of installation, any structures from corrugated board are erected in a short time.
The main advantages of the material are:
- high corrosion resistance;
- high mechanical strength;
- high reliability throughout the entire operational period;
- light weight corrugated board;
- convenience and ease of transportation;
- wide choose;
- ease and simplicity of frame mounting;
- high level of resistance to atmospheric action.
Decking is distinguished by its constant versatility, which allows the use of the material in different climatic conditions. The quality of the material is not affected by high humidity, low or high temperature conditions. Professional flooring is recommended for roofing in the construction of premises for various purposes, used for the construction of fences, as well as the walls of large buildings. The polymer coating of the corrugated board gives the material a decorative appearance, which makes it possible to use it in the construction of private houses and cottages.
Decking for fence
A modern solution for a cottage, cottage or any suburban area is a fence from corrugated board. Such a design will be reliable and durable in comparison with fencing made of mesh netting or wooden fences. Such a fence does not rust, does not need repair and will last more than 30 years. This type of corrugated board has excellent sound-reflecting properties, allowing to reduce the noise level from the outside.
For the fence, c8 corrugated board is often used, as well as C20 and C21. This choice is due to the special rigidity and strength of the corrugated board due to the thickness and shape of the metal. To equip the fence, one corrugated board will not be enough. Pillars, additional elements and transverse logs will also be required.
Since the fence is an element of the site, it lends itself to a huge environmental impact. Decking, sizes which can be ordered must have a polymer coating. It will give the material additional properties, and protect it from external influences. Such a corrugated board is quite easy to maintain, does not trap dust and dirt. Often, polyester and pural are used to cover it. But for more reliable protection choose a plastisol coating. Sometimes such a fence is covered with double-sided polyester, giving the material a more decorative look. If you did not find the required color of the corrugated board, then the fence can be painted in any color.
The advantages of a fence from corrugated board:
- - the possibility of acquiring sheets of different lengths;
- no need for additional processing;
- affordable price;
- manufacturability;
- solid protection against visibility.
Galvanized corrugated board
The production of corrugated board is done in a hot way: galvanized steel is machined to give a profile. Such corrugated board has high performance. Like any material, corrugated board has its drawbacks: low resistance to chemicals and reagents that precipitate with atmospheric precipitation. That is why the characteristic brilliance disappears over time. In addition, the galvanized coating is quite sensitive to mechanical stress: it is very easy to break the zinc layer and the unprotected area of the metal will be susceptible to corrosion.
Galvanized corrugated board can be used in such types of work:
- as a fixed formwork when pouring the foundation;
- for erection of canopies, garages, trade pavilions, change houses, construction of internal partitions;
- for cladding internal floors during construction in a frame-monolithic way;
- the construction of paneling enclosing structures;
- as a roofing for buildings of a large area.
