What We Make
We manufacture a full range of leaf springs from our own spring steel — including heavy-duty truck springs, light-duty truck springs, semi-trailer springs, Z-shaped air-suspension guide arms and cargo tricycle springs. Every spring goes through hot rolling, forming, heat treatment, machining and final inspection in our own production lines.
Built for long service life and reliable load-bearing performance, our leaf springs are supplied to truck, trailer and axle manufacturers, and have been fitted to vehicles under brands including BENZ and FREIGHTLINER.
Heavy-duty Trucks
Front and rear leaf springs for heavy-duty trucks and prime movers.
Trailers & Semi-trailers
Load-bearing suspension for flatbeds, lowboys and container chassis.
Light Commercial Vehicles
Light-truck springs, Z-shaped air-suspension guide arms and cargo tricycle springs.
Who We Work With
We work with truck manufacturers, trailer builders and axle companies worldwide. Our leaf springs have been fitted to vehicles under brands including BENZ and FREIGHTLINER, and we provide OEM and custom-made solutions according to drawings and samples.
Our Factory & Quality
We control the full chain from our own spring steel — hot rolling, forming, heat treatment, machining and shot blasting, with every spring tested for fatigue life, load capacity and hardness before delivery. This vertical integration means consistent quality, competitive pricing and reliable lead times for our customers.
