SPIFR Long Chain FR Metal Brass Zipper

Features

1. Continuous Chain for Industrial-Scale Production
Supplied in long rolls, the chain structure supports high-throughput sewing lines, allowing manufacturers to cut custom lengths and attach sliders as needed, maximizing efficiency and minimizing waste.

2. Metal Teeth with High Heat Resistance
The metal elements are manufactured to withstand elevated temperatures and maintain structural stability during exposure to sparks, convective heat, and short-duration flames — suitable for protective apparel and industrial equipment covers.

3. Flame-Retardant Tape Integration
The zipper tape is constructed using FR-certified textile materials (aramid/modacrylic options), preventing flame spread and ensuring the closure system complements compliant protective garment designs.

4. High Durability Under Repetitive Use
Metal teeth provide strong mechanical strength, reliable engagement, and resistance to deformation under repeated pulling, bending, and tension stress.

5. Ideal for Specialized Protective Gear
Widely used in flame-resistant coveralls, welding garments, firefighting gear, industrial uniforms, and equipment cases requiring metal strength + flame protection.
