SCREENFLEX PVC has been specifically designed to protect people from dangerous radiation and projection from hot metal during welding.
SCREENFLEX complies with international standards and regulations for “Health and Safety in Welding” (ISO 25980, EN 1598 in Europe and AWS F2.3 in USA)
SCREENFLEX vinyl is a product/solution to ensure safety and adhere to regulations. The SCREENFLEX product can be part of a fixed or mobile partition for all welding areas such as (automatic welding chains, welding shops, engineering factories, outside operations and welding in public areas).
