With much hard work in a difficult time in South Africa,  Rolyn Engineering grew.  In 1985 we bought the premises at 73 van Belkum Street, Rustenburg.  This has been the home of our Head Office since then.

In 1995 we started a long term relationship with Niagara Valves from Brazil. They manufacture a big range of valves in Cast Iron, Cast Steel, Stainless Steel and Bronze.

Niagara has been the number one valve manufacturer in Brazil (As voted by Engineering People accross the country) for many years. This position is due to producing high quality items at reasonable prices and good service.

In 1998 we opened our first Branch which is in Bloemfontein.  Soon there were more to follow.

Valsteam ADCA Engineering and Rolyn Engineering came together in 2001. We are now the sole agent for ADCA Steam Equipment in South and East Africa.

The ADCA Steam Equipment range is manufactured in Portugal to the highest standards.

We continue to grow and currently we have our Head Office in Rustenburg and branches in Benoni, Bloemfontein, Cape Town, Durban and Zambia.
