Steel Wire Reinforced Fiberglass Sewing Thread: Engineered for Extreme Performance

Unmatched Strength & Durability

Infused with high-tensile steel wire, this sewing thread delivers exceptional tensile strength (≥ 500N) and resistance to abrasion, ensuring long-lasting performance even in heavy-duty applications like industrial sewing, automotive upholstery, and outdoor gear manufacturing.

Heat & Chemical Resistance

Fiberglass core provides excellent thermal stability (up to 550°C) and resistance to most chemicals, acids, and alkalis, making it ideal for harsh environments where standard threads fail.

Precision & Versatility

Available in multiple thicknesses (10#-50#) and colors, it offers smooth sewing experience on automated machines, compatible with lockstitch, chainstitch, and overlock sewing processes. Perfect for bonding thick fabrics, leather, and technical textiles.

Weatherproof & Corrosion-Free

Steel wire reinforcement is galvanized for rust prevention, while fiberglass ensures UV resistance, making the thread suitable for outdoor use in marine, construction, and aerospace industries.

Why Choose Our Thread?

Designed for professionals who demand reliability, our steel wire reinforced fiberglass sewing thread bridges the gap between strength and flexibility. It’s not just a thread—it’s a solution for projects that require uncompromising performance.
