NIS extends capability with EN 1090 Execution Class 3

Having specialised in complex welding and fabrication techniques for more than 30 years we are delighted to have recently added to our capability by achieving EN 1090 Execution Class 3.

EN 1090 has four defined execution classes (EXC). Each class mandating its own set of requirements, with complexity and engineering effort increasing as the number rises. Though EXC2 is the most common specification, given our well established capability EXC3 was the standard we reached for and achieved.


This additional EXC3 accreditation will allow us to add to our core business streams of Mechanical Handling equipment, gloveboxes and containments to allow us to manufacture supporting structures made of steel up to strength class S700 and structural components made of aluminum alloys.


This is the latest in a series of improvements and investments that NIS are making to ensure we are ready to capitalize on the anticipated growth in many of our markets, specifically nuclear new build, and to accommodate our increasing  order book, particularly in the field of complex aluminum fabrications.

  • Investment in semi-automated welding equipment, making the process significantly more efficient than comparable manual methods with a far superior repeatable welding quality.
  • Participation in the Civil Nuclear Sharing in Growth programme, - One of only 10 UK companies to secure a place on this 4 year intensive business support programme with the primary purpose of making manufacturers globally competitive.
  • Expansion to our Welding expertise with NIS Weld Engineer achieving TWI Diploma in Welding Engineering,  the appointment of a junior weld engineer and the recruitment of more apprentices


To complement our manufacturing expertise,  we also have onsite some of the most highly skilled design and manufacturing engineers with an extraordinary attention to detail enabling us to produce the very highest quality products as demanded by the high integrity sectors we serve such as Nuclear, Security, Defence and Food.


Industry events, conferences and exhibitions provide a valuable platform for us to keep abreast of latest industry news, to identify emerging technologies and also to showcase our specialist capabilities to both new and existing clients.

We would be delighted to see you at the forthcoming events detailed below where one of our professional team will be available to answer any questions you may have about our wide ranging services.

If you would like to prearrange an appointment at your convenience please don’t hesitate to contact us. Please check back regularly as new event details are added to the calendar throughout the year.
