Definition and characteristics of the metal profile on the roof
The metal profile is a building material made from pre-galvanized steel. Strength is determined by its thickness of 0.12 centimeters. The production method is based on the cold rolling of hot metal sheets. The production goes through two stages:
- Metal profile sheet is treated with anti-corrosion agent
- The material is covered with
primer. On the outside, a mixture of building resins and plastics is applied. To obtain an even and attractive surface, colorants are added during the treatment. The reverse part of the sheet is covered with a layer of high-quality lacquer that protects the structure of the metal profile from damage.
The profile roofing material has a wavy appearance. Often produced by a trapezoid shape.
Roof profile has the following positive qualities:
- Sturdy structure;
- Light;
- Strength;
- Absence of propensity to ignite;
- Cost-effective price;
- Unprofessional installation scheme;
- Long-term use.
There are several categories of metal profiles( corrugated board):
- HC - designed for mounting walls and floor structures;
- С - fastening of a fence, walls;
- H - performs the function of coatings, partitions, roofing.
The roof profile falls under the last "H" point. It has excellent quality, standard parameters, strong structure. Has additional faces of rigidity. The height of its waves is optimal for the roof of the roof.
Small loads can withstand the metal profile under the category "HC".
The material model "H" is considered as an expensive option. Its main advantage is a long period of use. Durable. It can be operated under high pressure( it does not require a frequent step of the battens).
"NS" - corrugated board, used for roofs with a steep slope. It is a thin material and not expensive at a price.
The process of fixing the metal profile with their own hands
The installation of the roof has its own sequence, as it consists of certain layers of flooring. Before all the fastening is to determine the size of the profile and its number.
Consider in order:
- Make a measurement of the area of the roof structure. It is necessary to determine the length of the skates, the diagonal in meters and the crate. At final deducing of results it is necessary to take into account errors on possible overlap and a ledge of a roof eave. The correspondence between the length of the slope and the length of the profile sheet will be excellent. This option eliminates the need to further seal the connections.
- Sealing from water and ventilation. The metal profile is installed only with waterproofing, which protects the roof from leaks and condensation processes. The ventilation system is installed in the roof of any shape and angle of inclination. It removes the formed moisture. For a full air exchange, a construction is made from the slats with a span of 2 cm.
- Arrangement of the crate. It is the basis for fastening the metal profile. The choice of the material of the crate is based on personal preferences, the main thing is that the cross section of its components should be 3.2 by 10 centimeters. The bottom board must have a thickness greater than the top.
It is important to note: when installing on the roof of chimney, mansard and other openings, the load of the crate is increased by additional bars.
The roof is installed in a strictly chosen direction - from left to right, from right to left. You can not cover in chaotic order.
- Roof mounting. Starting the fastening of the metal profile, the sheet is placed in the center and screwed with a screwdriver. This step will align it on the cornice. All other sheets are fixed by overlapping and fixed firmly in the corners. The step of the fastening process is 55 centimeters for the horizontal type. Vertical - 30 centimeters. The initial 4 sheets are fastened by a stretched thread, which regulates their even position. The cover is mounted to the boards of the crate.
According to the building standards, snow traps should be installed on metal roofs. They will ensure the safety of the roof in the cold season.
Properties of the metal profile for the roof
There are certain features of the process.
The metal profile is fixed to the crate only between the waves. Self-tapping is fixed on the upper and lower parts of the ramp.
Assembly parts are installed with the help of combined rivets.
Screws should be screwed with an electric screwdriver or a drill. The installation process should not be sharp, it is better to operate at a low speed. A few months after mounting, the screws are tightened.
Note: It is forbidden to use nails( taking into account their ability to rust and damage the walls of the holes).
The measured profile for the roof also has its own cutting rules:
- It is possible to cut the metal profile with a saber saw, scissors with sharp blades - for transverse cutting. Scissors on metal - longitudinal
- It is not necessary to apply for cutting abrasive technologies. They cause the sheet to heat up, and its polymer surface and zinc layer undergo disintegration. This leads to corrosion of
Completion of installation work is marked by the cleaning of the remaining scraps. Possible scratches or damage to the surface of the metal profile on the roof are painted over with a polymer substance in the color of the sheets.
