Frequently Asked Questions — Carbonized Fiber Welding Blanket Rolls 4' Wide
Why choose the 4' wide roll over the 6' wide roll?
The 4' (48") width is the standard format for welding booth side panels and bay dividers where 48" matches typical welding station height. It produces less waste when cutting curtain-height panels and is the direct equivalent of the Steiner 316-48RF format. The 6' wide rolls are better suited for wider surface coverage, floor protection, and equipment wrapping requiring broader coverage in a single pass. See our Carbon Fiber Felt Welding Blanket Rolls for the 6' wide and other width options.
What lengths are available?
The 4' wide carbonized fiber welding blanket roll is available in 25 ft, 50 ft, and 100 ft lengths. The 100 ft roll is the most economical option for facilities with ongoing welding operations that regularly replace blanket material.
What temperature can this roll withstand?
Rated for incremental contact up to 1800°F (1000°C). FM Global, CFM (California Fire Marshal), and NFPA-701 certified for flame resistance.
Is this equivalent to the Steiner 316-48RF?
Yes. The 4' wide carbonized fiber welding blanket roll is a direct equivalent to the Steiner 316-48RF at a lower price point, with the same 48" width format and comparable 1800°F heat rating and FM Global certification.
How do I cut this roll to size?
Cut with scissors or a utility knife. The PANOX carbonized fiber material cuts cleanly without fraying, making it easy to produce precise curtain panels, blanket sections, or wrapping pieces in any length you need.
Is this material fiberglass-free?
Yes. PANOX oxidized PAN fiber contains no fiberglass — safe to handle without the skin irritation and respiratory concerns associated with fiberglass welding blankets.
What other welding blanket options do you carry?
We carry carbon fiber felt in pre-cut blanket format, wider roll formats, and fiberglass, silica, acrylic coated, silicone coated, and aluminized blankets and rolls. Browse the full Welding Blankets & Rolls collection for all options.
