Correct calculation of fasteners is a key stage of installation, which directly affects the durability and stability of the structure. Self-tapping screws provide fixation of panels, protecting the building from unfavorable weather conditions and mechanical damage. In this article we will understand the basic rules for calculating fasteners to install the panels as reliably as possible.
Rules for calculating fasteners for sandwich panels
Before starting calculations, it is important to take into account several factors. Among them:
The thickness of the sandwich panel. The thicker the panel, the more fasteners will be required for its reliable fixation.
Type of panel. Wall and roof panels require a different number of fasteners due to the peculiarities of installation.
Climatic conditions. In regions with strong wind loads, additional panel reinforcement may be required.
Base material. Different materials require different types of fasteners: wood, steel or concrete surfaces affect the choice and number of screws.
To calculate the standard norms that recommend using 5-6 self-tapping screws per square meter of sandwich panel. It should be taken into account that the edge of the panel and butt joints have more fasteners than the middle part.
Conventionally, we can distinguish the following stages of fastener calculation:
Determine the area of the panel. Find out the total area of each panel in square meters.
Calculation of self-tapping screws per square meter. For most panels use 5 self-tapping screws per square meter, but in some cases this number can increase to 6-7, depending on climatic conditions.
Additional reinforcement. Pay attention to the places of joints of panels and corners of the building, where reinforced fasteners may be required.
For an accurate calculation of self-tapping screws should take into account the size of the building and the type of panels. For example, to install 100 square meters of wall panels will require about 500-600 self-tapping screws. In the case of roofing panels, this figure may be higher, as the roof experiences increased loads from precipitation and wind. When calculating, it is also important to take into account the recommendations of the material manufacturer.

When choosing a material for construction, not only performance characteristics are important, but also compliance with the requirements of a particular object. Sandwich panels and bricks are two popular solutions, each of which has its own strengths. To understand which option is preferable, it is worth considering their features, advantages and limitations. Special features and […]
ПерейтиWhen designing buildings, attention is increasingly being paid not only to thermal insulation, but also to sound comfort. In the conditions of dense urban development and noisy environment noise insulation becomes an important task. An effective solution can be the use of sandwich panels, which combine heat and sound insulation properties, as well as ease […]

The choice of finishing materials in construction affects not only the performance of the building, but also its visual perception. This is especially true when choosing a facade cladding. Sandwich panels differ not only in strength and thermal insulation, but also in a wide range of color solutions. The right shade helps to emphasize architectural […]
