Import 3# Brass Long Chain Zipper — Buy in Bulk from Supplier in China

The 3# Brass Long Chain Zipper from Shenzhen Do-Well Industry And Trade ) Co., Ltd is a continuous metal fastening element manufactured from brass alloy, designated by the size code 3#, which denotes approximately 3 mm closed-element width when measured across the zipper teeth. This long-chain format is supplied as uncut continuous zipper tape, allowing garment and accessory manufacturers to cut to required lengths rather than purchasing pre-cut finished zippers. The brass construction offers corrosion resistance and a warm metallic aesthetic suited to visible applications in leather goods, denim, and premium outerwear.

Brass zipper teeth are typically die-cast from copper-zinc alloy (C26000 or C27000 grade, 60-70% copper balance zinc) and then plated or lacquered to prevent tarnishing; the slider and puller are commonly zamak die-cast with matching brass plating. Long-chain zipper tape substrate is typically woven polyester (standard 100D-150D) with a twill weave pattern that locks the metal elements during stitching. Element pitch for 3# brass zippers is standardised at approximately 5.0-5.4 mm, with tape width of 32-36 mm and tape thickness of 0.55-0.65 mm being typical industry norms for this gauge.

This zipper category serves luggage manufacturers, denim brands, leather workshops, and footwear producers who require custom-length closures with matching sliders and top/bottom stops. The long-chain format is particularly valued in bag production, where varying panel dimensions demand non-standard zipper lengths. Buyers should confirm with Shenzhen Do-Well whether sliders, stops, and bottom boxes are included or ordered separately, and what length increments or coil put-up standards apply to bulk orders. Trade terms, lead times, and exact alloy specifications require direct supplier confirmation.

Shenzhen Do-Well Industry And Trade ) Co., Ltd is based in Shenzhen, Guangdong Province, a principal hub for hardware and textile accessory manufacturing in China. The supplier carries an imported tier designation and a harbour trust classification, with a response rate of 0.00% and no recorded average response hours, indicating that buyer outreach may experience delays. No factory size, year of establishment, annual output, or major client references are provided in the available profile, so claims beyond the registered location and tier status cannot be substantiated.

The company lists the 3# Brass Long Chain Zipper as a core product, emphasising durability and aesthetic appeal, but the profile does not disclose quality management certifications (such as ISO 9001), environmental compliance (ISO 14001), or specific testing protocols applied to metal content and plating. Buyers are advised to request a supplier capability assessment, including machinery inventory (stamping, die-casting, plating lines), and to verify whether Shenzhen Do-Well operates its own plating facility or subcontracts this process, as plating quality is a common failure point in brass zipper supply chains.
