Anchor screw fiberglass support AVSP
AVSP screw fiberglass anchorage is used for fixing the roof and sides of preparatory and capital mining workings of mines and mines. Anchoring of the anchor in the hole is carried out by means of an ampoule with a polyester and /or mineral composition or by a mechanical locking method using a wedge-shaped lock. It is possible to use an AVSP type anchor in construction as an alternative to steel reinforcement.
- fiberglass rod;
- plastic support washer (it is possible to use a two-part washer);
- plastic nut;
- passport.
It is not capable of causing frictional sparking when interacting with moving mechanisms
Lighter than steel rebar rolled products of similar diameter by 9 times
It has a high tensile strength exceeding the tensile strength of steel reinforcing bars of similar diameter; it is not subject to corrosion
Does not accumulate an electrostatic charge
Does not have magnetic properties
