What's the difference between 'one leaf' and 'one set'?

One leaf refers to a single steel plate. One set is a complete assembly for left and right sides of an axle, typically including multiple leaves, center bolt, and clamps.

What is the warranty period for leaf springs?

Under normal use, warranty typically ranges from 6 to 12 months (subject to manufacturer's actual policy). Overloading, impacts, or improper installation are not covered.

When should leaf springs be replaced?

Replace when there are cracks or breakage in leaves, noticeable loss of elasticity causing sagging or uneven ride height, severe vibration, noise, or poor handling, or excessive wear between leaves.

AI-Powered supplier vetting

SummaryHebei Chenggang Metal Products Co., Ltd., founded in 1995, manufactures automobile and motorcycle leaf springs and operates one production line with stated annual capacity of 10,000 tons. It reports ISO9001:2008 certification and sales to more than 100 countries and regions, while export activity began two years ago and 41%–50% of sales are exports. The supplier supports extensive customization, ODM services, and reported new products during the past year. Quality inspection instructions are reportedly implemented uniformly, with two quality inspectors. However, service-management procedures, corrective actions, and complaint handling lack written records. The supplier has no overseas warehouses, showrooms, agents or branches, and has not participated in offline trade shows. Evidence of customer cases is limited to a general claim of international sales.

Supplier typeThe supplier is a manufacturer of automobile and motorcycle leaf springs, covering heavy, medium, light, micro and other vehicle types. Its stated manufacturing focus and product scope identify it as a specialized automotive component manufacturer rather than a general trading company.

CertificationsThe company states that it has passed ISO9001:2008 quality management system certification. This is explicit certification evidence, although no additional certifications or current certificate validity details are provided.

After-Sales capabilityThe supplier has written procedures for service assessment, corrective and preventive actions, and customer complaints, but reports no records for these processes. It also has no overseas warehouses, showrooms, agents or branches, and offers no overseas service coverage in the stated field, limiting demonstrated after-sales infrastructure.

R&D capabilityThe supplier reports two years of total R&D engineer experience, new products during the past year, and ODM service availability. These points support active product-development capability, although the limited stated R&D experience prevents judging the depth of its innovation resources.

Production capacityThe supplier operates one production line incorporating punching, cutting and product-forming equipment and reports annual leaf-spring productivity of 10,000 tons. Two quality inspectors and uniformly followed finished-product inspection instructions are also reported, providing explicit evidence of operating production and quality-control capacity.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization and flexible customization, and states that its leaf springs can be customized according to customer requirements. This is direct and consistent evidence of broad customization capability.

Client casesThe supplier states that its products have been sold to more than 100 countries and regions and that exports represent 41%–50% of total sales, with exporting beginning two years ago. However, no named customers, project examples or independently detailed case studies are provided.

Product Q&A

Q:What is a leaf spring?

A leaf spring is an elastic component made of single or multiple alloy steel plates stacked together. It is mainly used in suspension systems of trailers, three-wheeled motorcycles, trucks, cargo vehicles, and construction machinery to support loads, absorb shocks, and provide cushioning.

Q:What types of leaf springs are available?

Multi-leaf spring (high load capacity, cost-effective), Tapered leaf spring (lightweight, better ride comfort), Single-leaf spring (simple structure, lightweight design), and Graduated stiffness leaf spring (soft under light load, firm under heavy load).

Q:What vehicles typically use leaf springs?

Trailers, trucks, cargo three-wheeled motorcycles, agricultural vehicles, construction machinery, off-road vehicles, caravans, RVs, and special purpose vehicles.

Q:How do I know which leaf spring fits my vehicle?

Consider three key factors: Vehicle model / axle type, Rated load capacity, and Original spring specifications (number of leaves, length, width, arch). Providing these details ensures accurate matching.

Q:What materials are leaf springs made from?

Common materials include 65Mn (most common, high cost-performance) and 60Si2Mn (high quality, better durability).
