Standard Trailer Parts & Custom Forgings—Chengzean Machinery

Based in Shandong, we specialize in two main areas:

  1. Commercial Vehicle Brake Systems & Trailer Parts

Brake shoes, brake drums, brake chambers, slack adjusters, and other standard chassis parts for trailers, semi-trailers, and heavy trucks.

  1. Custom Forgings & Machined Parts

We produce parts based on your drawings or samples. This includes chassis components, connectors, structural parts, and other metal parts — supporting forging, precision machining, heat treatment, and more.

Our team has years of experience in related fields. We offer 24-hour quoting, support small trial orders, and can arrange third-party inspection.

Whether you need standard trailer parts or custom metal components, feel free to contact us.
