Import 5# Size Waterproof Long Chain Nylon Zipper — Buy in Bulk from Supplier in China

The 5# size waterproof long chain nylon zipper from Guangzhou Fengwang Technology Co., Ltd is a continuous coil fastener engineered for moisture-resistant sealing across extended lengths. The gauge 5 classification denotes 5 mm chain width when closed, a standard metric in zipper sizing that balances pull strength with tape flexibility. This listing specifies availability in gauges 3, 4, 5, 7, and 8, with the 5# variant occupying the mid-range suitable for medium-duty applications. The waterproofing is achieved through a coated or laminated tape construction that creates a barrier against liquid ingress when the slider is engaged, a feature that distinguishes it from standard open-weave nylon coil zippers.

The chain is manufactured from polyamide 6 (nylon 6) monofilament, a standard material for coil zippers due to its fatigue resistance and recovery after flexing. Typical tensile strength for gauge 5 nylon coil chain ranges from 250-350 N per chain direction, though the buyer should request the specific test method (ASTM D2061 or equivalent) and certified values from Guangzhou Fengwang Technology Co., Ltd. The long chain format supplies uncut metre-length rolls, allowing manufacturers to cut to precise garment or product dimensions and attach sliders separately. Standard coil counts per inch for gauge 5 are approximately 8-10 coils, contributing to smooth slider engagement and reduced snagging.

Primary applications span outdoor apparel (rain jackets, waders), marine and tactical bags, tent closures, and protective covers where sustained exposure to precipitation or spray is expected. Buyers in the workwear, military procurement, and camping equipment sectors represent the core demand for this specification. The supplier notes eco-friendly material claims, though the specific certification (Oeko-Tex, bluesign, or GRS) should be requested and verified before order commitment. Trade terms referenced include FOB and CIF options, with packaging described as transport-optimised; exact carton dimensions, roll lengths, and palletisation should be confirmed directly with Guangzhou Fengwang Technology Co., Ltd.

Guangzhou Fengwang Technology Co., Ltd is located in Huadu District, Guangzhou, Guangdong Province, China, within the dense manufacturing corridor of the Pearl River Delta. The supplier's registered address places it in a district with established textile accessory and hardware supply chains, though this does not independently confirm production capability or capacity. The trust tier is listed as harbour, and the response rate shows 0.00% with zero average response hours, indicating no inquiry history or non-responsive profile on the platform. Buyers should treat this as an unverified engagement and initiate direct contact to assess responsiveness and communication capability before relying on the listing for time-sensitive procurement.

The listing does not state factory ownership, production floor area, employee count, annual turnover, or specific clientele, and these should not be assumed. What is presented is a product-focused offering with trade term flexibility (FOB/CIF) and size customisation. The supplier claims eco-friendly materials without attaching certification numbers or scopes. A prudent buyer would request factory audit reports, ISO 9001 or equivalent quality system certificates, and physical samples with third-party test reports before committing to bulk production. The absence of response data means reference checks from prior buyers are particularly valuable.
