Focusing on the rigorous demands of heavy-industry and high-wear scenarios, this zipper combines metal stoppers, flame-retardant TC tape, and reinforced teeth to create a dual-upgraded "safety + durability" solution. With extreme structural strength and long-lasting protective performance, it is a professional supporting component for high-risk industries such as welding, metallurgy, construction, and high-durability flame-retardant bedding.
Core Advantages of Metal Stoppers & Structural Strength
- Metal Stopper Features: Made of high-quality brass/copper-nickel alloy via stamping, with nickel-plated/zinc-plated anti-oxidation surface treatment, resistant to rust and corrosion (passes 48-hour salt spray test) and no oxidative blackening during long-term use. Precisely sized (8mm×5mm), it engages tightly with teeth to prevent zipper slippage, with a load-bearing capacity of over 5kg (far exceeding plastic stoppers), suitable for fastening thick bedding fabrics (e.g., mattress covers, thickened duvet covers).
- Overall Durability: Size 5 nylon 66 teeth reinforced with glass fiber, heat distortion temperature increased to 250℃, flat pull strength ≥420N (per ASTM D2061 standard), and smooth operation without jamming after 1,200 cyclic opening/closing tests. Triple-thread woven TC tape passes 80,000 Martindale abrasion tests, with edge binding to prevent fraying and unravelling, resistant to high-frequency opening/closing and washing of bedding.
- Resistance to Harsh Environments: Tolerates industrial oil stains, high humidity (95% RH without mold), and mild acid-alkali corrosion (stable in pH 4-9 environments), maintaining consistent performance in complex industrial conditions (metallurgy, chemical industry, construction) and high-humidity scenarios (dormitories, hospitals). Metal stoppers offer impact resistance ≥80J, remaining undamaged after 1.5m drop, suitable for high-intensity work scenarios and friction/collision during bedding transportation and use.
Applicable Apparel, Bedding & High-Risk Scenarios
- Heavy-Duty Industrial Workwear: Welding protective clothing, high-temperature-resistant clothing for metallurgical workers, heavy construction coveralls, wear-resistant work clothes for mechanical maintenance.
- Special Protective Apparel: Fire-fighting auxiliary protective clothing, petrochemical explosion-proof flame-retardant clothing, high-temperature protective vests for power inspection.
- Outdoor High-Risk Workwear: Professional forest fire prevention clothing, geological exploration fire-resistant clothing, mine safety protective jackets.
- Heavy Equipment Accessories: High-temperature protective covers for industrial equipment, flame-retardant zippers for outdoor tents, fastening components for special tool bags.
- High-Durability Flame-Retardant Bedding: Heavy-duty flame-retardant mattress covers for industrial dormitories, flame-retardant duvet covers for mine/oil field worker dormitories, hospital ICU fire-resistant bedding (mattress covers, bed sheets), high-intensity use flame-retardant bedding sets for nursing homes, flame-retardant sleeping bags for high-temperature workshop rest areas.
Customization
- Specification Configuration: Standard Size 5 (5mm tooth width, 22mm tape width), customizable length (15cm-300cm; long lengths suitable for mattress covers and large sleeping bags), available in open-end (metal bottom stop + pin) and closed-end (metal bottom box) structures. Optional zinc alloy sliders (impact resistance ≥60J) with auto-lock function to prevent accidental opening (suitable for bedding fixation needs).
- Customization Services: Tape customization in solid colors, stripes, etc. (flame-retardant logos printable; dark colors like dark gray and navy for stain-resistant bedding). Metal stoppers with custom logos (laser engraving/stamping). Slider color options (black, silver, gold) matching apparel and bedding designs. OEM/ODM customization supported.
