FAQ

Frequently Asked Questions

Common questions about NOVASTAR™ Chopped Steel Fiber

What is Chopped Steel Fiber?

Chopped Steel Fiber is high-tensile steel fiber designed for concrete and composite reinforcement. It improves tensile strength, flexural toughness, and crack resistance.

How is it added to concrete or composites?

Add after aggregates but before water
Mix 3–5 minutes for full fiber dispersion

Can it replace traditional reinforcement?

Yes. Reduces or partially replaces rebar and welded mesh while improving durability.

What fiber lengths are available?

1–38 mm, customizable based on project needs.

Is it safe for industrial use?

Yes. Made from high-quality steel, corrosion-resistant, and safe for standard industrial applications.
