UNCOMPROMISING STRONG HOLD

The BZ3 dynamic stud anchor is the world's first mechanical expansion anchor with an evaluation/approval (ETA-20/0117) for fatigue loading. It is quick to install and enables immediate static action. This makes it an economical alternative to injection systems and undercut anchors.

Application area:

Anchorage of light to medium loads under fatigue loading
indoors and outdoors, both in cracked
and uncracked concrete:
Crane systems, industrial robots,
antenna masts, lift guides, conveyors as well as tunnel fastenings such as railings, signs, lights etc.

Advantages:

• European Technical Assessment in cracked and uncracked concrete under fatigue loading
• Also approved for use under seismic activity performance categories C1 and C2 and exposure to fire (R30-R120)
• Quick and easy installation, immediate static action
• Colour coding to indicate effective anchorage depth
• Versatile, for in-place and pre-positioned installation
• The use of a hollow drill bit eliminates the need to blow out the drill hole and prevents the formation of drilling dust
• Very low effective anchorage depths and minimum member thicknesses
• Small spacings and edge distances
• Economical alternative to injection and undercut systems
