Application

Steel fiber is used as a disperse material for the reinforcing of steel fiber concrete and torkete concrete. Quality parameters of steel fiber correspond to the requirements of ASTM A 820 (to a fiber of type I)

Steel fiber is certified by the Institution that fukfills the Certification of the building products "STATYBOS PRODUKCIJOS SERTIFIKAVIMO CENTRAS" regarding the correspondence to EN 14889-1:2006

Dimentions, shape and tolerances of steel fiber

d-fiber diameter, mm l -fiber length, mm λ - value (ratio l/d) h - hook height, mm

ℓ´, ℓ´* - length of hooked ends, mm

”, ”* - anchor length, mm

α’, α″ - bend angle, o
