North West mechanical Services have worked with Chemical Treatment Services for more than 7 years installing ultrapure stainless steel pipe work in several Hospitals across N. Ireland. The work involved orbital welding to a very high standard. On each occasion the work was carried out in a professional and timely manner. The Company has just completed two major installations for us in the Endoscopy Departments of the Ulster Hospital and Belfast City Hospital. We would have no hesitation in recommending North West Mechanical Services for similar works.
