Welding produces intense UV and infrared radiation, along with sparks and hot metal spatter — welders' skin and eyes can be exposed to ultraviolet radiation, with skin reddening similar to sunburn being the most common effect on people nearby. These hazards don't stay contained to the welder alone. A welding curtain creates a physical barrier that protects nearby staff from radiation exposure and flying debris.
If a workshop has more than one or two welding stations to screen, buying pre-made welding curtain screens for each bay adds up fast. A welding curtain roll — sold as a continuous length of material rather than a finished screen — lets you cut exactly the number and size of panels each bay needs from one purchase, at a lower cost per metre.
(Note: "welding curtain roll" is sometimes used for retractable, wheel-mounted roll-up screens rather than bulk material sold by the metre. This guide covers the latter — cut-to-length PVC roll stock.)
What is a welding curtain roll?
A welding curtain roll is welding-grade PVC supplied in bulk (typically 50m) rather than as a pre-cut, pre-hemmed screen. Our Screenflex Welding Grade PVC Bulk Roll is manufactured to meet ISO 25980 and AWS F2.3M requirements — the recognised international standards for transparent welding curtains, strips and screens — designed to shield against welding radiation and hot metal projection while remaining translucent enough to allow supervision through the barrier. It's available in red or green, and cut to length on-site — so it fits irregular bay widths without the waste of an off-the-shelf screen sized for a "standard" opening.
Why multi-bay workshops buy by the roll
For a single bay, a made-up screen is often the simpler purchase. But once you're fitting three, five, or ten welding stations, the maths changes:
One roll, multiple bays — a 50m roll can be divided across several stations, rather than buying separate screens per bay.
No wasted material — pre-made screens are sized to fixed dimensions; roll stock is cut to your exact bay width, so there's less offcut.
Consistent stock for future bays — if the workshop expands, matching material is already accounted for, rather than re-ordering a discontinued screen size later.
Lower cost per linear metre — buying in bulk roll format is generally more cost-effective than the same coverage split across individual pre-made units.
What to check before ordering
Standard compliance — confirm the product states the current welding curtain standard explicitly (ISO 25980 and AWS F2.3M are the actively maintained references), not just "welding grade."
Colour — red and green are both available. Check with the supplier whether colour affects protection level for your specific welding process, or is a site-preference choice — this can vary by manufacturer and shouldn't be assumed either way.
Width and thickness — 200mm x 2mm is the standard configuration for pedestrian welding bay traffic; confirm this suits your bay width before cutting.
Hanging system — sold separately; check compatibility with your existing rail/hook setup or bay structure.
Ventilation is separate — a welding curtain contains radiation and debris, but it isn't a substitute for fume extraction. Welding fume is subject to the COSHH Regulations, and HSE publishes specific advice sheets on welding, cutting, and surface preparation to help you comply. Confirm your extraction setup independently of curtain specification.
Rolls vs pre-made screens vs portable frames
Buy by the roll if you're fitting three or more bays, bay widths vary, or you expect to add stations later. Buy a pre-made screen if you have a single, standard-width bay and want a ready-to-hang unit with no cutting or sourcing a hanging system required. If bays need to move or be reconfigured regularly — rather than fixed in place — a portable, frame-mounted screen may suit better than either option; SCD's roll and made-to-measure ranges are built for fixed installations, so speak to us if your setup is mobile.
FAQs
How much welding curtain roll do I need per bay?
This depends on bay width and whether the curtain needs to wrap corners or overlap for full coverage — as a starting point, measure the full opening width and add overlap allowance per strip.
Does welding curtain roll meet UK safety standards?
Our Screenflex welding grade PVC is manufactured to ISO 25980 and AWS F2.3M requirements — check that any product you're comparing states the current standard explicitly.
Can one roll size fit different bay widths?
Yes — because it's cut to length, a single roll can be divided to fit bays of different widths, unlike a fixed-size pre-made screen.
Does welding curtain colour affect safety?
Confirm with your supplier — colour may or may not correlate with protection level depending on the manufacturer's material spec, so don't assume based on colour alone.
