Mining anchors are an important part of the product range manufactured in KGHM ZANAM S.A. The anchors we manufacture are divided into two main product groups:

•    expansion anchors; the set contains: a rod, a head and a washer
•    resin anchors; the set contains: a rod, a nut and a washer

In both product groups the user can select washer shape and type. The above housing elements are also offered separately from the kit. Anchor rods are available in sizes from 0.6 to 3.2 m and are made of a bar with a diameter of 18 mm.
KGHM ZANAM S.A. is currently one of the three major manufacturers of anchor supports in Poland and the largest supplier of anchors to such companies as KGHM POLSKA MIEDŹ S.A. or PeBeKa S.A. We also process orders for gypsum and anhydrite mines, as well as companies providing mine construction services.
Manufactured anchors are used mainly for constructing ceiling in underground mines, while shorter anchors are used as auxiliary tool in transport tunnels.
The manufacture line which was implemented and launched in late 2012 allows for precisely and accurately adapting the product to customer requirements. The product may also be freely modified as part of the prototype product execution.
