Extra-heavy filaments (0.8-1.8mm diameter) provide stable rigidity under extreme mechanical loads while maintaining optimal surface contact to eliminate mill scale, pickling residue, and oxide layers without steel surface damage. Superior fatigue resistance ensures consistent cleaning performance through millions of high-speed rotations in continuous production environments.

Chemical-stable formulations withstand acidic pickling solutions, alkaline cleaners, and hot water immersion while preserving filament integrity and cleaning efficiency across extended production runs.
