Comparative Advantage

Tongya Automobile is a privately owned enterprise, where operations across departments are well coordinated for maximum efficiency. TONGYA is located within easy reach of various raw materials necessary for semi-trailer manufacture.

We own one of the 5 largest production facilities presently found in Chinese semi-trailer industry. Private ownership means we can make the best use of our money and equipment to carry out production flexibly. Our workers are paid for each part they make or each task they do, rather than being paid hourly. That is why we can participate in the work more actively than you have ever seen.

Our tank semi trailer has earned us a reputation in China and is the preferred choice by Chinese trailer users. Compared with factories located in Southern or Central China, we have geographical advantages by locating us within close proximity to water ports.

Production facilities are constructed close to each other, which facilitates integrated management and mass production.

We hire 128 senior technicians, and 80 semi-trailer designers who have at least 5 years of hands-on experience in what they are doing now. At TONGYA, semi-trailers can be custom designed to individual requirements.

Production Capacity
Our production facilities have altogether a floor area of 160,000 square meters. Outfitted with 18 semi-trailer production lines and 12 tank trailer lines, our plants are capable of producing 600 sets of semi trailers per month.

We are located in Liangshan County, one of Chinese manufacturing hubs for semi-trailers. There are plenty of trailer parts manufacturers around us, from whom we can source only the best parts for our semi trailers. The close proximity to Port of Qingdao, Port of Tianjin, and Port of Shanghai allows us to ship your ordered trailers at a low cost.
