The Cobalt team is ready to help you with your specific requirements

Cobalt Engineering is a privately owned South African entity that focuses on the manufacture of standard and specialized semi-trailers, custom-built to meet the challenges set out by the diverse and expanding haulage industry.

The company was founded in 1993 by York Zonneveld whose creativity and vision set Cobalt on its path of becoming pioneers in the transport industry. Cobalt strives to make a difference by continuously finding innovative and simple solutions to the unique and complex requirements of each and every client. Cobalt Engineering has gone from strength to strength as we work with our customers to create reliable trailers that are lower, wider and stronger in order to meet their specific needs- from bulk handling to abnormal freight.

Cobalt consistently strives towards the improvement and streamlining of our processes- from investing in more durable or cost-effective trailer solutions to maintaining better customer relations that are professional and interactive. Cobalt stands by its products and endeavours to assist the customer from the trailer’s inception throughout its ownership, bringing peace of mind that our trailers can be relied on to do the job. 


The fully comprehensive SABS approved manufacturing facility is based in Chamdor Krugersdorp. We have an on-site, highly skilled and integrated team to assist with any and all requirements our customers might face.

Our factory boasts a fully functional and highly skilled ground team that is equipped with all the necessary equipment and machinery to complete the assembly process efficiently and timeously. Our in-house design team works closely with other members of the production process in order to maximize efficiency and product quality.

Cobalt Components (Pty) Ltd supplies Cobalt Eng. with all the necessary cylinders, hydraulics and other components needed to complete our trailers.
