Quality and safety

Dias Welding and Mechanical Engineering has been servicing the sootblower market in South Africa since 1995. Our absolute focus on quality drove us to become the first sootblower company in South Africa to get our welding SAIW ISO3834 Part 2 certification. We also have ISO 9001:2015 quality management certification.



We don’t just push new equipment on you if you don’t need it – we engage with you and create a proposal that outlines available options and gives you choices. Once any repair or maintenance work begins, we keep you involved in the whole process, from the initial stripping and assessment to the repair work, testing and final quality checks.



For maintenance and repairs, we are able to source many of the parts locally, passing on significant cost savings to you. Where we can’t source locally, we have an extensive international supply chain that enables us to import parts and equipment at the best prices and quickest lead times. You also save with our ability to recondition and repair sootblowers and get them working like new again without the expense of having to buy completely new sootblowers.
