Jeans Buttons & Rivets: Zinc Alloy and Stainless Steel Hardware for Denim

April 30, 2026 163

In the production of jeans and denim apparel, buttons and rivets are crucial details that determine quality. Compared to standard garment trimmings, denim buttons and rivets must withstand greater tensile forces and repeated friction, placing higher demands on materials and craftsmanship. Choosing the right hardware supplier can enhance the durability of the finished garments and help reinforce the brand’s professional image.

I. Material Selection for Denim Buttons and Rivets

Zinc alloy is the most commonly used material for denim buttons. When manufacturing denim buttons, Songji selects high-purity zinc alloy raw materials and utilises patented moulding technology for one-piece forming. This process ensures the button edges are smooth and burr-free, preventing damage to denim fabric, whilst guaranteeing smooth fastening and long-lasting durability.


Zinc alloy denim buttons offer high malleability, allowing for a wide range of shapes and surface finishes, making them suitable for both minimalist and decorative designs. Coupled with relatively controllable costs, they are the material of choice for most denim brands.


For high-end denim brands or functional denim garments, stainless steel is a superior option. Stainless steel denim rivets possess excellent corrosion resistance and are unlikely to oxidise or rust, even after repeated washing and prolonged wear. Some of the high-end denim buttons produced by Songji are made from stainless steel, meeting export inspection requirements and capable of meeting the stringent standards of leading international brands.


Copper is the classic material for traditional denim rivets. Copper rivets oxidise naturally over time, creating a unique vintage effect that adds a retro charm to denim garments. Songji also offers custom copper denim rivet services to meet the needs of brands seeking a vintage style.

II. Core Technical Requirements for Denim Buttons

Denim buttons must withstand the weight of denim fabric and the repeated tugging of daily wear. Songji’s standard tensile strength test for four-hole buttons is no less than 35 kg, whilst special hook-and-eye fasteners exceed 300 kg, ensuring a secure fastening that will not come undone.


Denim garments often undergo washing, stone-washing, and even bleaching processes; the metal fittings must withstand these treatment processes. Songji subjects all denim buttons to salt spray testing, with standardised protocols for both 24-hour and 50-hour durations at a 1% concentration, ensuring the surface plating remains as bright as new after repeated washing.

Given the thickness of denim fabric, the button and rivet holes must be precisely aligned to ensure a flat, even fit. Songji implements strict tolerance control standards during production to ensure dimensional consistency across every batch of denim buttons, facilitating large-scale manufacturing.


III. How to Select a Denim Button Supplier

Choosing a supplier with ISO 9001:2015 certification guarantees the standardisation of their quality management system. Songji also holds OEKO-TEX Standard 100 Class I certification and GRS certification, ensuring that its products meet international environmental standards and are compliant with export inspection requirements.
