Brass Coated Micro Steel Fibres
The construction process uses various steel and concrete elements, among which is the ground-breaking Ultra-High-Performance Concrete (UHPC). Ultra High-Performance Concrete (UHPC) displays a compressive strength at least 10 times greater than conventional concrete. Using UHPC concrete for applications that involve high-strength materials and durability properties is becoming more common in concrete structures and buildings. These types of concrete are versatile and provide an array of benefits. Brass-coated micro steel fibres are specifically designed to be added to ultra-high-performance concrete (UHPC).
Brass-coated steel fibre is a reinforcement fibre used in construction materials like UHPC. Where the strength of the UHPC falls between 120MPa to 150 MPa, brass-coated micro steel fibre is used with the concrete.
It involves coating steel fibres with a layer of brass using electroplating. The steel core provides strength and durability, while the brass coating offers corrosion resistance and improved bonding. It’s commonly used in applications requiring high strength and durability, such as tunnel linings, safety solutions, and other high-performance concretes. Compared to other fibres, brass-coated steel fibre is more durable, corrosion-resistant, and provides better bonding with the surrounding material.
Shape: Brass coated Micro Steel Fibres are brass-covered steel needles with straight-in-shape
Compatibility: It can be incorporated with curing compounds, superplasticizers, water reducers, hardeners, and coatings, making them a great choice for any construction project.

Applications:
Stainless Steel Fibres are suitable for a wide range of applications across concrete and refractory structures. Key applications include:
- UHPC: Stainless steel fibres enhance the strength, toughness, and durability of precast concrete elements and ultra-high-performance concrete (UHPC). They improve load-bearing capacity, crack resistance, and extend service life.
- Tunnel Linings & Shotcrete: They provide superior reinforcement in tunnel linings and sprayed concrete (shotcrete), offering resistance against dynamic loads, spalling, and shrinkage cracks, ensuring long-term stability and safety.
- Marine & Coastal Structures: Stainless steel fibres significantly increase corrosion resistance in harsh saline environments, making them ideal for jetties, sea walls, bridges, and offshore platforms. They help reduce maintenance and extend structural life.
- Refractory Castables & Linings: Stainless steel fibres improve thermal shock resistance and mechanical strength in refractory linings, minimizing spalling and cracking at high temperatures. They ensure longer life for furnaces, kilns, and boilers.
- High-Temperature Applications: With excellent heat resistance, stainless steel fibres maintain integrity in extreme thermal conditions. They are suitable for chimneys, incinerators, and other structures exposed to fluctuating high temperatures.
- Defense & Security Structures: Used in blast-resistant and impact-resistant concrete, stainless steel fibres enhance energy absorption and crack control. This makes them ideal for bunkers, protective shelters, and sensitive infrastructure.
- Hydraulic Structures: Stainless steel fibres improve water-tightness and durability in dams, canals, spillways, and water-retaining structures. They provide resistance against erosion, cavitation, and freeze-thaw cycles.
