Serrated anti-slip elements (serrated)
Despite the fact that the lattice flooring already in the standard version has excellent anti-slip characteristics (especially for welded flooring due to the twisted cross bar), in some applications it is necessary to provide additional lattice protection against slipping. In such cases, the lattice flooring can be made of a strip with anti-slip teeth.
Types of anti-slip teeth:
S4 - tooth " saw " - gives the maximum non-slip effect.
S5 and S6 - Two anti-slip options such as " trapeze " They have the same anti-slip effect and differ only in manufacturing technology. The S5 tooth is more common
ATTENTION :
When choosing a lattice flooring of the SERRATED type, it is necessary to take into account the reduction factors of the maximum allowable loads. You can find these coefficients in the Technical Handbook in the « Load Tables »
Recommendations for choosing a lattice floor with anti-slip teeth
Lattice flooring of the SERRATED type should be used where there are conditions of increased risk of slipping, for example, in places where lubricants, emulsions, possible contamination or icing, etc. are used. SERRATED decking is also used in cases where the platforms are installed not in a horizontal position, but at a certain angle.
