About Weierxin

A trailer manufacturer and vehicle exporter based in Shandong, China.

Who we are

Shandong Weierxin Automobile Co., Ltd. is a trailer manufacturer approved by the Ministry of Industry and Information Technology, and a used-vehicle export enterprise licensed by the Ministry of Commerce.

We build new trailers, semi-trailers, urban vehicles and special vehicles in our own 25,000 m² factory in Liangshan County, and we prepare and export trucks of all major brands from our Jinan office.

Where we build

The factory is in the Quanpu Town Industrial Park in Liangshan County — the trailer cluster of Shandong. It has an exhibition hall, a preparation workshop, a sandblasting room and a paint room, plus CNC cutting and automatic welding equipment.

That means the frame, the body and the paint are all done under one roof, which is why we can hold a delivery date instead of waiting on a subcontractor.

Certification

The factory holds ISO 9001:2015 (certificate 30323Q20872R0S) for the manufacture of semi-trailers within its licensed scope, plus CCC certification.

Our export operation has been audited on site by SGS (report QIP-ASI255217) and holds an Intertek assessed supplier certificate (473155892_T).
