Specification

Heavy-duty anchor for high loads in cracked and non-cracked concrete. Zinc-plated steel

Proof of Performance

ETA-02/0031 for individual attachment, option 1, cracked and non-cracked concrete, seismic performance category C1 and C2

Fire resistance: F30, F60, F90 and F120; exposure to fire according to DIN 1363-1:1999-10 (uniform temperature-time curve)

Application area

Create the drill hole

Clean the drill hole

Application area

Individual attachment with approval

Normal concrete C20/25 to C50/60 (cracked and non-cracked concrete, seismic performance category C1 and C2 for sizes M8–M20)

e.g. metal structures, metal profiles, brackets, base plates, supports, cable conduits, pipes, railings, machines etc.

Individual attachment without approval

Can be used in concrete < C20/25 and compression-proof natural stone
