J Marston Engineers Ltd

J Marston Engineers is a long established family run firm specialising in stainless steel and sheet metal fabrication generally associated with ‘clean air and containment engineering’.

We trade throughout the UK from our Leeds manufacturing base and have operated consistently from this same location for over 45 years.  We are committed to quality control and assurance in all our activities and are independently certified with accreditation to BS EN ISO 9001.  To further support the quality of our products a 3 Year Manufacturing Warranty is included as standard.

We are also certified as meeting the financial, technical and managerial requirements of the Dti initiative – ConstructionLine – See Certificate No.43972.   All our site operatives are 100% CSCS Registered.

Sheet metal, tubular steel and stainless steel manufacturing are in-house.  Sub-contracting of specialised services is limited to powder coated finishes.  Investment has been made to automate all standard sheet metal folding and punching operations with CNC equipment, however many traditional hand fabrication skills are still regularly employed and this is recognised throughout the industry as one of the highly favoured attributes of this Company.

Let us find a solution that is right for you!


After comparing other competitors, Marston Engineers prices and their ‘first contact’, it was an easy decision to make. Excellent service from start to finish. Top quality products and a company who are easy to deal with. Courteous, helpful and very mindful of our needs at all times.

Thank you for all the hard work Marston Engineers has undertaken in installing and setting up the freezers. The work was undertaken very professionally and your engineers are to be commended on the quality of the work, their attitude, and their ability to work as a team with our staff at all times. The installation went well, and the freezers are now working. Brrrrrr!
