Key Features

• Premium Stainless Steel Construction: Made from high-grade stainless steel for excellent corrosion resistance and easy maintenance, ensuring the spring stays reliable even through years of daily use.
• Rectangular / Square-Profile Design: The rectangular cross-section delivers a more stable, evenly distributed supporting force compared to round-wire springs — ideal for applications requiring consistent, long-term structural support.
• Z-Type Structure: The Z-type geometric profile allows the spring to generate greater elastic force, making it well-suited for high-performance equipment and demanding load-bearing assemblies.
• Fatigue-Resistant: Engineered to withstand repeated compression and extension cycles without loss of tension, maintaining its original performance characteristics over an extended service life.
• Versatile Application: Perfect for sofa frames, seat cushion supports, furniture repairs, mechanical equipment, DIY projects, and more.
• Silver Finish: Clean, neutral silver tone blends seamlessly into any furniture or equipment assembly.
• Dimensions: 1.3 × 9 × 25 × 245mm
• Material: Stainless Steel
• Color: Silver

Frequently Asked Questions

Q: What are the exact dimensions of this rectangular flat spring?

A: This stainless steel rectangular flat spring measures 1.3 × 9 × 25 × 245mm. The precise sizing makes it suitable for sofa frames, furniture assemblies, and mechanical equipment applications requiring consistent elastic support.

Q: What makes the Z-type structure on this flat spring beneficial?

A: The Z-type geometric structure allows the spring to generate a greater elastic force relative to its size. This design is especially valuable in high-performance equipment and load-bearing assemblies where a strong, reliable spring action is essential over extended use cycles.

Q: How does the stainless steel material benefit this spring's longevity?

A: Stainless steel provides excellent resistance to corrosion, oxidation, and wear, which means the spring maintains its structural integrity even after prolonged exposure to humidity or friction. It is also easy to clean, making it a low-maintenance choice for both furniture and mechanical applications.

Q: Is this spring suitable for sofa repairs?

A: Yes — this rectangular flat spring is widely used in sofa and upholstered furniture frames. Its square-profile design distributes supporting force evenly, enhancing the stability and service life of seating assemblies.
