Safety nets are used on the one hand to catch falling persons and on the other hand to protect people from falling materials. Wherever balls are played with, safety nets are used to prevent them from leaving the terrain or injuring someone. Many bridges are secured by safety nets so that no one can fall off the bridge or objects can fall off it. In this way roofs, railings and buildings are secured. So-called bird protection nets serve to prevent birds from tampering with the plaster. This disturbs the building structure sensitively! Steel nets protect passing motorists from falling rocks.
Due to the many clearings of entire mountain slopes, debris and rocks are no longer kept on the ground. They threaten to fall onto the road and injure passing people. In the circus, trapeze acrobats are protected by these nets. In amusement parks, adventure worlds, etc., safety nets are stretched everywhere where people move over open spaces. In children's playgrounds, protective measures such as those for the ball pool are mandatory. Sports fields are also protected by nets. In the zoo, the aviary is protected by nets to prevent the birds from flying away. Some areas are protected with nets to prevent objects or small children from falling into cages, ponds, etc.
What do these nets consist of and what is important?
Almost all nets are made of robust, durable plastic yarn, such as polypropylene filament yarn. These materials must be able to absorb heavy weights quickly and reliably at high speeds. It is not only the material that matters, but also the way it is processed, sewn, chained, knotless or knotted interlaced, wide-meshed, coarse-meshed, square, interwoven, etc. In addition, the strength of the fibres and whether they are suitable for outdoor or indoor use are decisive. Especially for children it is important that the material is 100% non-toxic. For outdoor use, the nets must be UV-stable and weatherproof. The nets must withstand temperatures between - 40 and + 80 °C. Since these nets can come into contact with various materials and stability must still be guaranteed, the following properties are an absolute must:
Acid resistance: good - very good
Alkali resistance: good
Resistance to organic solvents: good
Resistance to petrol and lubricating oils: good
UV stabilization: at least 300 kly
Weather resistance: good
Tear resistance after 2 years of continuous exposure to weathering: 90
The maximum mesh tension (e.g. 250 N) and the Oeko-Tex certificate 12.0.02466 are relevant for the quality of safety and protective nets
How is the high safety standard maintained?
Manufacturers of safety products check their products regularly and at the highest level to ensure the protection and safety of their customers. After all, their lives depend on it! Furthermore, public institutions and commercial enterprises are obliged to observe certain safety standards and to comply with the relevant regulations, laws, ordinances and guidelines. This also includes proper and regular maintenance.
safety inspections are carried out at irregular intervals by the authorities
Special features of nets in modern bridge construction!
Primary ropes, steel structures are processed with Webnet into daring but safe designs. Different mesh sizes and rope diameters are used. Modern systems combine passive with active protection devices. Bridges are among those structures that need to be secured and protected not only during the construction phase but also for decades to come. Therefore, particularly strict rules and regulations apply here
In the public sector, particularly strict regulations apply with regard to safety and protection. Nets are used to catch both materials and people. Regular inspections are vital. This type of nets is being used more and more in the construction industry in particular. The second most important area is the children and sports sector. The manufacturers also carry out quality controls. The nets must be dimensionally stable over many years and resistant to acids, heat, cold, alkalis and solvents. These nets make a decisive contribution to protecting many thousands of people.
