Product Overview
Dongguan Seme Precision Hardware Co., Ltd. (SEME Hardware) is a professional manufacturer of fire damper constant force flat coil springs – also commonly referred to as flat coil constant force springs or stainless steel constant force springs.
Made from premium stainless steel (301/304), these constant force flat coil springs deliver consistent, stable force throughout their entire working range. This makes them ideal for fire dampers, retractable cords, cable reels, and various industrial mechanical assemblies requiring reliable retraction or counterbalance.
With strict material selection and precision manufacturing processes, our custom fire damper springs ensure reliable performance, long service life, and minimal maintenance in both standard and harsh environments.
Specialized for Fire Damper Systems
Our constant force flat coil springs are specifically optimized for fire damper systems in HVAC and building safety applications:
✅ Reliable Emergency Closing Force – Provides consistent torque to ensure the fire damper closes reliably during emergencies, meeting safety code requirements (e.g., UL, EN).
✅ High Temperature & Corrosion Resistance – Stainless steel construction maintains stable performance even under high-temperature conditions and in humid ventilation environments.
✅ Long-Term Functional Stability – Designed to remain functional for years without force decay, ensuring the damper operates correctly when needed.
✅ Space-Efficient Design – Compact flat spiral form factor fits easily inside standard fire damper housings without interfering with airflow.
Product Features
✅ Consistent Constant Force Output – Maintains steady tension throughout the extension cycle, ideal for retraction and counterbalance applications in fire dampers and cable reels.
✅ Premium Stainless Steel Material – Excellent corrosion resistance, high fatigue strength, and long-lasting performance in humid, high-temperature, or industrial environments.
✅ Flat Spiral / Coil Design – Compact form factor allows for space-efficient installation in fire dampers and other confined mechanical assemblies.
✅ High Fatigue Resistance – Designed for thousands of cycles without significant force decay, reducing replacement frequency and maintenance costs.
✅ Fully Customizable Specifications – Custom force ratings, coil dimensions (width, thickness, outer diameter), end configurations (straight, hooked, or custom tangs), and surface finishes to match your exact design requirements.
✅ OEM & ODM Support – We manufacture constant force springs to your drawings, samples, or performance specifications – from prototype to bulk production.
