The cladding of GRID-ALWA (80-800) type gives the possibility of changing the applied technologies of ceiling or wall strutting, and its innovative application makes it possible to reduce the costs. It is easy to apply and it increases the safety of conducted works. It is intended for underground sites mining hard coal, in the mines of copper, zinc or lead ore, for the protection of embankments, slopes and excavations, and also in construction industry.
The cladding is made from long polyester fibres with huge elasticity and strength coefficient, which are anti-static and non-flammable material. Moreover, this product is resistant to bases, acids and other chemical substances. It is light (1kg per 1m2), corrosion-resistant (extended product life) and it is characterised by huge tensile strength.
Vertical and transverse section points of polyester fibres form a net consisting of even squares and strong nodes, which enables the full use of their mechanical properties. The application of innovative technology shall to a large degree facilitate the performance of strutting in longwall excavations, it will enable the easy fitting of the cladding to the excavation profile, thus increasing safety of executed works. This product has a simple structure and it is safe to use.
