DonFiber ST Type I
High performance steel fibers with hooked ends for reinforcement of concrete and mortar (Formerly known as ST Fiber Type 1)
DonFiber ST Type I is steel wire filaments with hooked ends. Steel fibers are designed for use with all types of concrete mixes to enhance mechanical properties and reduce plastic shrinkage cracking.

- Increases in load bearing capacity.
- Increases in flexural bending strength.
- Increases in fatigue and abrasion resistance.
- Greater impact resistance and improved resistance to dynamic loads.
- Reduction in shrinkage cracks due to full depth reinforcement distribution.
- Economic advantage such as reduction in section thickness and construction time.
- 1 - 2 hours fire rating.
DonFiber ST Type I is ideally designed for use in the following applications:
- Shotcrete.
- Tunnel segments.
- Pre-cast concrete.
- Industrial floors.
- Composite decks.
- Pavements.
- Slabs on piles.
- Foundation slabs.
- Shear reinforcement in prestressed elements.
- Slab-on-grade.
DonFiber ST Type I is available in 20 kg and 25 kg bags.
Store under cover away from heat sources.
The guidance dosage of DonFiber ST Type I is 10 - 60 kg per m3 of concrete. Representative trials should be conducted to determine the optimum dosage of DonFiber ST Type I to meet the performance requirements by using the materials and conditions in actual use.
Note:
- A dosage of ST Fiber Type I at a rate of 3,000 - 4,000 pieces in m3 of concrete will diagonally intercept the propagation of any initial crack, this will maintain that the maximum crack width - if happen - will not exceed 0.3 mm.
DonFiber ST Type I complies with ASTM A820, Type I and EN 14889-1.
