STB Engineering Ltd Information

STB Engineering was founded in Stroud in 1969, pioneering the development of Dense Phase pneumatic conveying technology, silo manufacture and powder handling systems. The company established itself as the UK’s leading Bulk Materials Handling and Pneumatic Conveying Specialists. Our early Dense Phase systems found favour with the likes of the Milk Marketing Board and the Polymer industries, where the need to transport high volumes of powders over long distances with minimal degradation was paramount. This type of conveying was more hygienic and was found to require far less maintenance than mechanical conveying techniques. Many of the early systems installed are still in operation today, performing to their original specification after 30 years’ continuous service. More recently, there has been a trend towards vacuum systems, and this has proven especially popular in the field of plastics and PVC extrusion. Today, the STB Vacuum Line Feed System feeds more major PVC extrusion plants in the UK and Ireland than any other type of system, bearing testament to its proven performance and reliability. STB has also acquired complementary expertise in batching and weighing systems in the food, pharmaceutical, plastics, chemical and mineral industries. STB is the UK market leader in the supply of mixing plants to the polymer industry. In 2015 STB Engineering Ltd became official supply partners for Hennlich Engineering in the UK, and since 2023 STB Engineering have the capacity to offer Weld Overlay Cladding services in house. From 2025, STB Engineering added certified compliance with the requirements of BS EN ISO 3834-3:2021 and 3834-2:2021, to complement our ongoing certification and compliance to BS EN ISO 9001 and BS EN ISO 1090.
