This 7 mm spiral steel boning is made from high‑quality galvanized spiral steel with a 0.9 mm wire thickness.
It is flexible, shape‑retaining and ideal for couture, bridalwear, costume design and professional corsetry. Thanks to its spiral structure, the boning bends smoothly in multiple directions without kinking — internationally known as double‑spring boning or two‑way spiral boning.
Supplied on a 10‑meter roll, it can be easily cut to any required length. Use it in boning channels, casings, linings or structural seams to shape dresses, bodices, corsets and costumes with precision.
Spiral steel boning is certified according to Oeko‑Tex® Standard 100, ensuring it is tested for harmful substances and safe for direct skin contact — essential for bridal and couture garments. Preferably used with tunneltape for an optimal result.
