#3 Metal Close End Zippers are engineered for durability, ideal for secure, non-separable closures. Compatible with #3 metal or nylon tapes, their precision-molded brass or stainless steel teeth offer superior strength. Weighing 6–9g per 30cm, with 3.8mm tooth height and 20mm tape width, they balance heft and function. Standard finishes include Polished Nickel, Antique Brass, and Matte Black, with custom Pantone coloring available for brand alignment.
The permanent closed-end design, with a fixed bottom stop, prevents accidental separation, perfect for single-compartment items like jeans fly zippers. Their industrial-grade metal construction withstands 12kg pull force and 8,000+ open/close cycles, excelling in heavy-duty use. Rust-proof electrophoretic plating ensures weather resistance, passing 48-hour salt spray tests. Precision-engineered sliders reduce friction to <15N, enabling smooth operation even with thick fabrics or gloves.
In fashion, they add a classic look to jeans and jackets. For accessories, they secure handbags and wallets. Industrially, they are used in tool pouches for durability and in upholstery for a neat finish. Their versatility makes them suitable for a wide range of products.
Customize with antique, brushed, or hammered finishes and Pantone-matched tapes. Branding via laser-engraved logos on sliders or embossed tape edges is available. Functional upgrades like locking sliders for anti-theft and extended pull tabs for cold weather enhance usability.
