John Mayes Engineers is a family-run engineering company with over 50 years of manufacturing experience. We specialise in the fabrication of pipe fittings for use in the petrochemical, process, energy and allied industries, and are known throughout the UK for the quality of our components and the speed of our service. Established in 1959, John Mayes Engineers have a proven track record of delivering close tolerance components with extremely short lead times. 

Everything we do is geared towards meeting our customers' requirements. Our aim is to deliver exactly what they need, exactly when they need it – because if a customer wants an item for tomorrow, it’s no good telling them delivery is going to take a week! We understand the pressures you’re under and appreciate the demands of the market - and we know that delivery is as critical as quality, price and materials. 

To ensure we’re able to meet these demands, John Mayes Engineers have invested in some of the fastest, most accurate CNC equipment available on the market. It’s these machines that allow us to process materials so quickly and to switch between jobs as and when we need to. 

The size of our company has an impact on the way we work. We’re large enough to be able to handle multiple orders, yet small enough to provide a personal service. We have a team of experienced engineers who have been with the company for many years, and who are committed to delivering exceptional products and providing outstanding engineering services. 

Our paperwork is very good too. We have invested in bespoke software that enables us to check materials, produce certification to customer requirements and send out emails as required. It’s just one of the ways in which we’re able to help our customers with their production schedules.

If you would like to find out more about John Mayes Engineers and the services we provide, please visit our website or get in touch directly on 01842 753400. 

We look forward to hearing from you.
