Welding Blanket Roll 150 ft

The STEINER 372-40R is a fiberglass welding blanket roll measuring 150 ft in length and 3 1/4 ft in width. It provides a continuous protective barrier rated to withstand temperatures up to 1,000 Degrees F. The material is uncoated, tan in colour and weighs 18 oz/sq yd. Grommets are placed on each corner and spaced 24 in apart for secure fastening.

Light Duty Spark Shield

This blanket suits light duty welding and cutting operations where spark and abrasion resistance are required. The heat cleaned finish makes it ready for immediate use in fabrication shops or on-site work. Buyers needing heavy duty protection or a coated material for molten metal splash should evaluate alternative products.

FM Approved 1000 Degrees F Rating

The decisive specification is the FM Approved temperature rating of 1,000 Degrees F combined with the uncoated fiberglass construction. This defines the safe operating envelope for light duty spark and spatter protection. Verify that your application stays within this thermal limit before purchase.

Questions about this item

When will the fiberglass blanket need to be replaced?

The blanket is rated for light duty and resists abrasion and sparks, so it lasts until physical damage or heavy wear reduces its protective coverage.

What limits continuous use at the 1,000 °F maximum temperature?

The uncoated 18 oz/sq yd fiberglass material handles 1,000 °F, but prolonged exposure at that limit can degrade the fibers faster than intermittent use.

Does the blanket generate heat or noise during all-day welding jobs?

The passive fiberglass roll produces no noise or heat of its own; it simply blocks sparks and radiant heat up to its 1,000 °F rating.
