Purpose and user

The STEINER 376-3X4 is a welding blanket sized at 3 ft by 4 ft, built for welders and metalworkers who need a portable barrier against spatter and sparks during medium-duty jobs. Its black acrylic-coated fiberglass construction suits shop floors, fabrication bays and on-site repairs where a quick-deploy shield is required.

What the accessories change

Grommets placed two per corner on 24 in spacing let the blanket hang from hooks, chain or rope without tearing, turning a flat sheet into a suspended curtain or vertical screen. The acrylic coating adds abrasion resistance while keeping the 0.05 in thick fiberglass flexible enough to fold for storage between shifts.

Installation and common issues

The blanket unfolds and hangs in seconds using the corner grommets; no tools are needed beyond a suitable anchor point. Installers sometimes underestimate the 28 oz/sq yd weight when mounting overhead, so support hardware must handle the load. FM Approved rating confirms the material meets the tested flame-resistance standard for the stated 1,000 Degrees F maximum temperature.

Questions about this item

How often will the acrylic-coated fiberglass need replacing under medium-duty welding?

The blanket is rated for medium duty and resists abrasion, sparks and spatter; lifespan depends on exposure intensity and care, but the FM-approved material is built for repeated use.

What is the first limitation reached during prolonged high-heat work?

The acrylic-coated fiberglass withstands up to 1,000 °F; sustained temperatures above that will degrade the coating before the base fabric fails.

How much heat does the blanket radiate back into the workspace during all-day use?

The 0.05 in thick, 28 oz/sq yd fiberglass insulates rather than radiates, keeping the work area cooler while containing spatter and sparks.
