Let's start with the measurement and calculation of the profiled sheet. How much does it cost to buy?
A short description of the corrugated board is contained in the video in the adjacent tab:
The laying of the corrugated board is simple and does not require additional education or specialist involvement. It is important to correctly measure and calculate the material. We recommend that you adhere to the following principles.
Use two rules for calculating the required amount of corrugated board - manual and electronic( calculation by special computer program-calculator).The majority trust the accuracy of the electronic device and distinguishes a number of its advantages:
- Automatic accuracy
- Strict adherence of the computer to the specified algorithm of actions
- Calculation of the most complex construction objects
- Calculation of the roof area and its ramps slope
- Calculation of the number of corrugated board. Selection and calculation of the roofing material volume and for other roof elements
- The parameters of the program provide for the selection of the appropriate color of the corrugated board, creating a visual appearance of the future structure of the
. We make an independent calculation: the length of the
corrugated board. Independent calculation does not involve complex processes. It is important to remember that it will not always be performed accurately. Small buildings, simple in their design( garage, bath, annex), have an uncomplicated plan of the building, their parameters are calculated independently.
The profilist is placed on a special base - a wooden crate made of rough boards with a thickness of 2 centimeters. It fits across the ridge design in steps of 20-30 centimeters. The volume of the roofing depends on the area of the roof and the angle of inclination of its ramp.
The roof has a completed view with the installation of a hydraulic barrier( vapor barrier) and thermal insulation. Its number is determined by the area of the roof. It is important to leave a small percentage of overlaps - vertical and horizontal.
Vertical depends on the profile, are made with the closing of waves( waves can differ from different manufacturers).
Horizontal depends on the roof slope:
- Slope up to 15 degrees implies overlapping from 200 millimeters
- 20-30 degrees - 120-200 millimeters
- From 30 degrees - 100-150 millimeters
Measurement of roof overhang parameters
The length of the profiled sheet and its height determine the parameters of overhangs. The height of the profile wave is directly proportional to its ability to withstand the load. The profiled material must be metallic and have an average length. The cladding is placed with a distance of one and a half meters. With this approach, the roof is able to withstand a semitone kilogram per square meter. A smaller profile wave is mounted with a small step, and a continuous crate can be mounted.
How many profilers are required
Profiled sheeting has the following parameters:
- working width - 110 centimeters
- total width - 118 centimeters
The skates length is measured initially and the result is divided by the width of the profiled sheet. The final number is rounded up by a larger number. The overlap is taken into account in this way of calculation: 118-110 = 8 centimeters.
The length of the corrugated board consists of the lengths of the cornice installation, the vertical overlap and the roof slope. The vertical overlap is 15 centimeters, the cornice is 5 centimeters. Therefore, the minimum length corresponds to a mark of 50 centimeters, the maximum - 600.
Sheets of corrugated board are placed horizontally.
We consider the parameters of the additional parts. Their length is 2 meters. Fold the length of all the roof rajids, the result is divided by 1.9.We leave an overlap of 10 centimeters. For the parameters of the valley we divide by 1.7, overlapping - 30 centimeters.
Number of screws - for 1 square meter we take up to 8 pieces.
It is important to note: a small roof slope and a simple building layout requires the same calculations and miscalculations of the required material. Do not need to be measured by eye. It is better to make special drawings and on them to determine the number of profiled sheets and other construction parts.
How much is corrugated board: we determine the financial part of
The cost of corrugated board depends on the roof area. The area should be divided into the area of the sheet. The calculation calculator is multiplied by the cost of one profiled sheet.
Preliminary calculation of the number of sheets will give the rough results of the amount of expenses. When buying it is important to take into account overlaps and take materials with a margin. The chosen color of corrugated board will probably be in short supply, when repair is required, which once again confirms the need to purchase the material in larger quantities.
