Polypropylene coarse fiber, also known as plastic steel fiber or steel-like fiber, is a refined product made primarily from polypropylene and polyethylene through special production processes. It features a rough surface, distinct outline, excellent dispersibility, and strong adhesion to cement matrices. This product combines the functions of steel fibers with the advantages of synthetic fibers, mainly used to replace welded metal meshes and steel fibers in concrete panel structures.

Usage:

Carbon fiber reinforcing bars, primarily used in concrete panel structures, enhanced and locally enhanced concrete structures, and shotcrete projects for roads, railways, tunnels, and culverts, are single fiber materials made from polymer fibers, processed and treated through special techniques. They are characterized by high strength, high modulus, low elongation, and non-polluting properties. They can replace steel fibers for crack resistance and enhancement in cement concrete. They maintain the original traditional concrete fiber's bondability, high-temperature stability, fatigue durability, and low-temperature crack resistance, while significantly improving the workability and dispersibility of fibers in concrete, allowing for more even distribution of the main loads across the entire concrete structure. They possess high strength, corrosion resistance, high-temperature resistance, strong chemical stability, strong grip with concrete, resistance to aging and erosion, resistance to acids and alkalis, and anti-magnetic and anti-rust properties... They play a more three-dimensional role in reinforcing and bridging. Moreover, they are easy to install and do not harm equipment.

Road surfaces, bridge decks, airport runway surfaces, apron surfaces, wharf yard surfaces, panelled rockfill dam surfaces, industrial building floors, warehouse floors, etc., are used to enhance the crack resistance, flexural tensile strength, flexural toughness, impact resistance, and fatigue resistance of these panel structures.
