• Core Function: Primarily used for shaping and structuring. Sewn into the inner layer of the garment, they make the clothing more crisp and structured, effectively supporting the body's curves to achieve desired wearing effects such as tummy control and bust lift.

• Primary Applications: Their usage is extensive, covering nearly all garment categories requiring shaping and support, including:

  • Intimate Apparel: Bras, shapewear, corsets

  • Ready-to-Wear: Wedding dresses, evening gowns, dresses, shirts (for specific areas like collars)

  • Specialty Clothing: Waist trainers, swimwear

• Common Materials: To ensure adequate support and resilience, steel bones are typically made from metal materials. Common types include high-manganese steel, galvanized steel, stainless steel, and nickel-titanium alloy (also known as memory steel boning). To prevent rust and enhance comfort, some products feature surface treatments like plastic coating or paint finishing.

• Common Forms: Depending on the application, steel bones come in various forms:

  • By Shape: Available as long, thin stripes (spiral or straight stays) and curved rings (bra underwires).

  • By Cross-section: Available in flat and round wire types.

  • By Construction: Range from simple metal strips to safety-style bones equipped with plastic tips or polymer end caps at both ends, facilitating sewing and preventing the bone from piercing the fabric.

• Process Features: In use, steel bones are typically not sewn directly onto the fabric. Instead, they are inserted into a slender fabric channel (often called a "bone casing" or "channeling") for fixation, allowing for flexibility and replacement. Furthermore, some high-end products employ techniques like seamless bonding or full coating to enhance wearing comfort and durability.
