SF Type-I N

SF Type-I N


SF Type-I N “Needles” fiber products by Nycon are 0.2 mm diameter x 13mm mono-filament steel fibers for use in creating fiber-reinforced concrete (FRC). These fibers are designed for use in concrete products as a primary reinforcement. SF-Type-I Needles are coated with copper to resist corrosion.

Meet the requirements of ASTM A820.

Available in bulk quantities only. Reach out for estimate.

SF TYPE I steel fibers can be added directly to the mixing system during or after the batching of the ingredients and mixed at high speed for a minimum of five minutes. Additional mixing does not adversely affect the distribution or overall performance of-SF TYPE I steel fibers. The addition of SF TYPE I steel fibers at the normal recommended dosage rate does not require any mix design or application changes. A water reducer or super-plasticizer is recommended in concrete products where improved workability and finishability are desired.
