Suttons, which specialises in bulk liquids and chemical logistics, is investing £9.5 million in ISO tanks to meet the increasing demand for its specialist service.
This brings the total investment in ISO tanks to more than £20 million in the last two years, almost doubling the size of its fleet.
Last year Suttons spent £6 million on 400 new ISO tanks as part of its international expansion.
Its latest order was for a total of 600 tanks from China and South Africa with the first batch being delivered to Suttons in May.
Suttons has renewed its contract with Oleon, the European producer of oleo-chemicals and Harvest Energy, an independent blender and supplier of road fuels and leading forecourt retailer.
Andrew Palmer, group managing director of Suttons, said: “The international division continues to grow and we have seen significant growth in some of our key markets. However these are challenging times but we remain confident about our performance and ability to continue delivering a safe, reliable service for our customers.”
