Welding curtains are designed for use in workplaces where bystanders must be protected against the hazardous radiation emitted during welding work. They provide protection against dangerous Blue Light and Ultra Violet (UV) rays. In case of prolonged exposure these rays can cause actinic conjunctivitis and even cataracts. All our welding curtains comply with ISO EN 25980, the European standard. Our welding curtains also have a standard width of 140 cm (4´ 7.1"), are provided with a 5 cm (2") seam on horizontal edges, 7 suspension eyelets at one 140 cm (4´ 7.1") side and snap-fasteners on both height sides.
