Application

Application area

Individual fixing point with approval

Normal weight concrete C20/25 to C50/60 (cracked and uncracked concrete, seismic performance category C1 and C2)

For the attachment of e.g. metal structures, metal profiles, brackets, base plates, supports, cable conduits, pipes, railings, wooden structures, roof beams etc.

Individual fixing point without approval

For use in concrete < C20/25 and pressure-resistant natural stone

W-FAZ/A4 (stainless steel A4) can be used in dry indoor areas, outdoors (including in industrial atmospheres and close to the sea) or in wet rooms, provided that no particularly aggressive conditions are present.
