This is especially useful when refurbishing existing equipment where the original manufacturer no longer exists. Speak to our team to find out more about the process.

We manufacture to all major end-user material and testing specifications. Product is fully tested and certified to requirements and delivered with the necessary paperwork such as databooks, Inspection Test Plans, accelerated weathering tests, inspection and sampling reports.
