Most of the indoor invisible protective nets are installed outside the outdoor wall, and a layer of aluminum alloy material is installed up and down, which is fixed with expansion screws. Punch a whole steel wire in series on the aluminum alloy material every 4.5 cm or so, and reinforce each vertical invisible steel wire horizontally with a cross code.
There is no big safety problem when the invisible guardrail is used for one or two years. If the time is delayed for four to five years, the protective layer on the surface of the thin steel wire is easy to rust due to aging, and the transverse steel bar cross will rust and loosen with pliers, which greatly reduces the protective performance of the whole invisible guardrail.
