GST prides itself on state-of-the-art machinery and two centuries of combined mining experience. At GST, we utilise our computer numerical control ‘CNC’ machines, plasma cutters, robotic welding and conventional machinery, allowing us to be self-dependent in manufacturing our own unique and universal components.

We strive to meet all local and international legal regulations in mining, manufacturing and engineering, as required by our client’s individual needs as well as our environment. We are ISO 9001:2015 accredited and follow strict quality control procedures and safety protocols. This contributes to our flawless and effortless production, allowing us to appreciate and perfect the smallest component right through to the final product.

Each of our designated workshops is overseen by skilled artisans operating according to a specific trade. Our experienced draughting department, making use of the latest Computer Aided Draughting (CAD) software, ensures that from concept to final design, our manufacturing is backed up with complete confidence and accuracy.
