How to choose a quality metal profile for drywall?

The metal profile for gypsum plasterboard, covered with zinc, is one of the most modern building materials, which is increasingly used in a variety of repair works. That is why a similar product of different quality begins to appear on sale, and not all samples meet the reliability requirements, and therefore will not be able to perform their functions long enough. Know what distinguishes the metal profile for high-grade gypsum plasterboard from the short-lived, is necessary and for those who use the services of builders to be convinced of the correctness of the ratio of price and quality.

First, the production of such a profile has its own tricks. The galvanizing process allows the resulting profile frame for gypsum board, protected from corrosion. To do this, the zinc content in the upper layers of the material should not be less than 99.9 percent. If this figure is significantly lower, such a metal profile for drywall can not be used. A poor-quality frame will undergo particularly rapid corrosion in a humid room and, thus, the thinned metal is deformed under the pressure of other materials or even collapses.

Therefore, it is important to know that the painted profile types are not always materials with an additional level of protection against the destruction of metal. Most likely, in this case, the manufacturer is trying to hide the zinc coating inadequately high-quality composition. In addition, the metal profile for gypsum board, covered with paint, is inconvenient during the installation of the frame, because the upper layers of the paint immediately separate and create extra garbage.

In addition to coating methods, there are other "pitfalls" in the manufacture of these building materials. When choosing a ceiling profile for gypsum board or any other similar profile for carcass assembly, it must be taken into account that its thickness should not be less than the established standard in 0,5 - 0,6 mm. Such a metal will be reliable, while more thin types assume additional work on the installation of reinforcing bars.

Very often, to hide the real thickness of the metal profile, the producers make its surface perforated. Then the material is not only difficult to measure and evaluate, it will be inconvenient in the process of work.

In fact, knowing these basic tricks, choosing a quality profile for the skeleton is not so difficult. The most reliable way is to consider a large number of its species in one store. The difference in samples differing in price, will be noticeable and to the touch. But a rigid profile with a smooth structure and longitudinal ribs of strength is exactly what you need. The surface of such material should shine in the light, which indicates the observance of all requirements for galvanizing. Low-quality composition, on the contrary, will be cloudy and dull.

The choice of the metal profile and the timely verification of its quality level is a responsible process, since the removal of the adverse effects from bad materials will take even more time and effort.
