Welcome to Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer with over 25 years of experience in precision spring production. Our Rectangular Compression Spring (1.5mm Wire, 8mm OD, 25mm Free Length, Spring Rate 500N) is designed to deliver reliable performance in demanding applications where space is limited but high force is required. As a factory established in 1998, we combine traditional craftsmanship with modern manufacturing techniques to produce springs that meet international standards. With an annual export value of US$5–10 million and a global client base spanning North America, Europe, Asia, and beyond, we are committed to providing durable, high-quality spring solutions for your mechanical assemblies.
This rectangular wire compression spring offers distinct advantages over conventional round wire springs. The rectangular cross-section provides a higher load capacity within the same installed space, making it ideal for applications such as automotive suspension systems, industrial machinery, aerospace components, and precision tools. Below we detail the key specifications, features, and benefits that make this spring a smart choice for your engineering needs.
Key Specifications

| Material | High Carbon Spring Steel (e.g., 65Mn, SWPB) |
| Surface Treatment | Plain / Oil Dipped (optional: zinc plating, black oxide) |
| End Type | Closed and Ground (standard) |
| Packaging | Standard packaging (plastic bags, cartons, or as requested) |
Product Features & Benefits
- High Load Capacity in Compact Space: The rectangular wire profile allows the spring to handle 500N per mm of deflection while occupying minimal radial space. This is particularly beneficial for applications where outer diameter is constrained (e.g., 8mm bore).
- Consistent Spring Rate: Each spring is precisely wound and heat-treated to ensure a linear spring rate of 500 N/mm, providing predictable performance under compression. Tolerances are maintained according to DIN 2095 or equivalent standards.
- Durable Material Selection: Made from premium spring steel with excellent fatigue resistance. The material can withstand repeated cycles without significant set loss, ensuring long service life in dynamic environments.
- Versatile Surface Options: Standard plain finish is suitable for indoor or oil-lubricated applications. For corrosion resistance, we offer optional surface treatments such as zinc plating, black oxide, or phosphate coating (available upon request).
- Precision Ground Ends: Closed and ground ends provide flat seating surfaces, reducing buckling risk and ensuring even load distribution. This is critical for high-speed or precision assemblies.
- Customizable Dimensions: While this listing specifies 1.5mm wire, 8mm OD, 25mm free length, and 500N spring rate, we can adjust wire size, outer diameter, free length, and spring rate to meet your specific requirements. Our factory is equipped with CNC coiling machines and automated testing equipment.
- Standard Packaging for Safe Delivery: Springs are packed in anti-rust paper and sturdy cartons to prevent damage during transit. Bulk packaging or custom labeling is also available.
Why Choose Our Rectangular Compression Spring?
Compared to round wire springs, the rectangular cross-section offers up to 30% more energy storage capacity for the same volume. This means you can achieve higher forces without increasing the spring's outer diameter, making it the preferred choice for tight-fit assemblies like valve springs, clutch mechanisms, and die springs. The 1.5mm wire thickness combined with 8mm OD provides a balance of flexibility and strength suitable for moderate to high load applications.
Our manufacturing process includes strict quality control at every stage: from raw material inspection (certified mill test reports available) to dimensional measurement using digital calipers and spring testers. Each batch is sampled for load testing to ensure the spring rate meets the specified 500 N/mm. We also perform fatigue testing on representative samples to guarantee the spring's durability under cyclic loading.
With a factory located in Hengshui, Hebei – a renowned hardware manufacturing hub in China – we benefit from a mature supply chain and skilled workforce. Our annual production capacity exceeds 10 million springs, enabling us to fulfill both small prototype orders and large OEM contracts. We ship from Tianjin, Qingdao, and Shanghai ports, ensuring timely delivery to customers worldwide.

Frequently Asked Questions
-
Q: What material is used for this spring?
A: The spring is made from high carbon spring steel (e.g., 65Mn or SWPB). We can also use stainless steel or other alloys upon request. -
Q: Can I get a different spring rate?
A: Yes, the spring rate is customizable. We can adjust wire dimensions, number of coils, and free length to achieve a different rate. Please provide your target load and deflection. -
Q: What is the maximum compression length?
A: The maximum compression (solid height) depends on the number of coils. For this spring, typical solid height is around 7–8mm. We recommend not to compress beyond 80% of the free length for optimal fatigue life. -
Q: Do you offer surface treatment for corrosion protection?
A: Yes, we offer optional zinc plating, black oxide, or phosphate coating. Please specify your requirement when ordering. -
Q: What is the minimum order quantity?
A: Our MOQ is generally 100 pieces for standard sizes, but we can accommodate smaller quantities for prototyping. Contact us for details. -
Q: How do you ensure the spring rate accuracy?
A: We use computerized spring testers to measure load at specified heights. Tolerances are maintained within ±5% of the rated spring rate. -
Q: What packaging is used for export?
A: Standard packaging includes anti-rust paper, plastic bags, and corrugated cartons. For bulk orders, we can use palletized packaging with stretch wrap. -
Q: What are the delivery times?
A: For stock sizes, delivery is 3–7 days after order confirmation. For custom orders, lead time is typically 15–25 days depending on quantity.
