Predictable rate
It defines the actuation point and force in a brake or valve mechanism.
Springs for Commercial Vehicles — Brake, Valve and Return Mechanisms
In a brake circuit or valve assembly a spring runs through millions of cycles. Here, load deviation is measured not in component life but in the reliability of the whole system.

Operating conditions
What the spring faces in this industry
Road conditions and frosts down to −40 °C demand predictable rate and resistance to brittle fracture.
- Road conditions: shock loads, vibration, dirt, moisture and de-icing agents.
- Winter operation: on some routes frosts reach −40 °C, making resistance to brittle fracture critical.
- Brake and valve assemblies: millions of load cycles over the service life.
- OEM quality system requirements: documentation, traceability and batch consistency.
What this means
Requirements for the spring
Compression and torsion springs for brake and valve mechanisms: a stable rate batch after batch, steels and coatings for cold climates, documents for OEM quality systems.
Fatigue resistance
Cyclic loads accumulate — the coil surface is strengthened by shot peening.
Sub-zero operation
Steel grade and heat treatment are selected for cold-climate service.
Documents for quality systems
Test reports and product data sheets for incoming inspection and audits.
Products for the industry
Which springs we offer
You don't have to pick from a ready list: we manufacture to drawings, samples or technical specifications.
Advantages
What this means for your order
Proof, not promises
Quality control of every batch
What removes the risks of sourcing from China
- NDA on request Drawings and technical documentation are never shared with third parties or used for other customers.
- Prototypes in 48 hours You test the samples first — series production is agreed only after your approval.
- Reports for every batch Load, geometry, hardness — with measurement protocols and batch traceability.
- Document package for EAC IATF 16949:2016 certificate, test reports and product data sheets — for declaration and customs.
- Payment in CNY Payment terms and channel are agreed individually before the order is signed.
- Delivery to Russia Rail, road and sea freight via the Far East. Incoterms: FOB, CIF, DAP.
How to start — three steps
- 01
Send a drawing or a sample
PDF, DWG, DXF, a sketch or a physical sample. We sign an NDA on request.
- 02
Get a price and lead time
Our engineer checks manufacturability and proposes material and coating — we reply within one business day.
- 03
Test prototypes in 48 hours
After alignment we produce prototypes and ship them to you. Then — a series batch with inspection and documentation.
FAQ
Questions about Trucks & Trailers
Are you ready for a supplier audit?
Yes. The factory operates to IATF 16949:2016, we are ready for audits and can arrange a video tour of production on request.
How do you confirm batch characteristics?
We measure geometry, check load and rate, and issue reports. The inspection plan is agreed with the customer.
Do you sign NDAs for automotive component drawings?
Yes, we sign a confidentiality agreement: customer documentation is never shared with third parties.
Which materials do you use?
Spring steels 65Mn, 72A, 82B, 60Si2Mn, 55CrSi, 51CrV4, 60Si2CrMn. Wire is sourced directly from Baowu (Baosteel), Kobe Steel, Bekaert and Qingdao Special Steel, which guarantees characteristic consistency.
How do you deliver products to Russia?
We arrange rail container transport, road freight and sea shipping via Far East ports. Delivery terms are agreed per order (FOB, CIF, DAP).
Can we sign a confidentiality agreement?
Yes, we work under NDA: customer drawings and technical documentation are never shared with third parties or used for other customers.
