In the process of using corrugated board as a roofing material, it is necessary to purchase additional accessories. This category includes many parts, including corners for corrugated board. Corners or, as they are also called, fractional elements perform a number of important functions, without which the work will not be considered complete.
Peculiarities
A corner for a profiled sheet is a specific device that performs important functions, such as:
- closure of the outer and inner rib sections;
- edging of the edge zones of the material;
- protection of some areas from dust and moisture.
If you refuse to use the corners, then the work with the material will not be considered complete. Such corners are made in factories by specific bending of the profiled sheet.
Views
The corners for the profiled sheet differ from each other not only in size, but also in color.
At the same time, starting parts are produced in one color, and then painted in different shades.
In addition, there are several types of corners
- Ridge strips . Among this category, several more subgroups can be distinguished: rounded, simple and U-shaped. Their purpose is to protect the ridge structure.
- Fractional elements of the valley . Here, too, two varieties can be distinguished: upper and lower. The purpose is to protect the concave corners as well as the lower sections of the roof from moisture.
- Abutment strips - these corners are used if the main roof needs to be connected, for example, to a chimney. And also they are often used in the design of complex roof structures.
-
Cornice strips
-
Internal and external corners
- Droppers designed to remove moisture.
- Snow holders - these are special devices that are designed to stop snow from going down.
Most of the above elements are used precisely at the final stage of roofing work. But, for example, droppers must be installed in the process of laying the profiled sheet.
Corners, regardless of their category, are metal (unpainted) and painted
How to choose?
The choice of corners for the profiled sheet must be approached responsibly. At first glance, it seems that these elements do not play a particularly important role . But very often it is on them that the durability of the entire structure and the quality of roofing work (no leaks) depend.
In the process of choosing corners, it is necessary to initially determine what kind of fittings will be required to perform the work . Usually, a complete set is bought, since the entire roof needs to be processed. But when carrying out repair work, it may be that some kind of separate view will be required.
When choosing fittings, care must be taken to match the colors of the finish and the profiled sheet itself installed on the roof. Of course, you can choose a great color, but it will not look very aesthetically pleasing.
When buying corners, you should pay attention to the quality of the material from which the parts are made . It should not be too thin, because even during the installation process, parts can deform. Poor-quality fittings are quite difficult to screw onto the profiled sheet and, in general, to use for their intended purpose. It is best to purchase corners in proven places that work directly with manufacturing companies.
Mounting
Installation work for the installation of this type of fittings is not particularly difficult. This requires a minimum set of hand tools that can be replaced with a screwdriver.
The installation of the corners is carried out by the correct selection of parts . That is, if it is necessary to process the cornice, then it is necessary to purchase and install the cornice strips. To connect the chimney to the main roof, it is recommended to use another type - junction strips. For the installation of snow guards, the appropriate parts must also be used.
To securely fix the fittings, it is necessary to use high-quality self-tapping screws . Installation is carried out using these fasteners. It is very important to fasten fittings with high quality, since tightness in this matter is the key to success.
