Welding Blankets | Heavy Duty Fireproof Weld Blankets

Steel Guard Safety manufactures heavy duty welding blankets engineered to protect workers, equipment, and surrounding areas from sparks, slag, spatter, UV radiation, and radiant heat during welding, brazing, cutting, and heat-treating operations. Available in fiberglass, silica, carbon fiber, and silicone-coated fiberglass — each material is purpose-engineered for specific temperature ranges and welding applications, with continuous protection up to 2,000°F depending on material selection.

Unlike imported alternatives, every Steel Guard welding blanket is manufactured in the USA and meets both NFPA-701 and FM Global Standards for flame resistance. Compare our quality directly against Tillman, Steiner, and Black Stallion — we’re confident you’ll see the difference in material density, edge finishing, and long-term durability. Custom sizes are available on every blanket in our lineup, with stock sizes available for immediate online ordering.

Choose the Right Welding Blanket for Your Application

Not all welding blankets are built for the same conditions. Material selection matters — the wrong blanket for your temperature range or welding process will fail faster and provide less protection. Here’s how our five welding blanket materials compare:

Knight Armor — Carbon Fiber Welding Blankets

Our highest-performance welding blanket — engineered from carbonized PanOx fiber felt for extreme heat and heavy spatter applications. Knight Armor blankets provide superior protection in arc welding, plasma cutting, and high-heat industrial operations where standard fiberglass blankets would degrade rapidly. Rated for the most demanding welding environments in our lineup.

White Spark — Silica Fabric Welding Blankets

Woven from high-purity silica yarn for continuous service in extreme temperature environments. White Spark silica welding blankets are ideal for furnace applications, heat treating, and high-temperature welding operations where fiberglass would reach its limits. Also available in roll form for DIY custom-cut applications and high-temp fire resistant barriers.

Red Spark — Silicone Coated Fiberglass Welding Blankets

A silicone-coated fiberglass blanket offering enhanced resistance to molten metal splash, abrasion, and chemical exposure compared to standard fiberglass. Red Spark blankets are well suited for foundry work, heavy fabrication, and environments with significant molten metal or chemical splash hazards.

Slag Shield — Acrylic Coated Fiberglass Welding Blankets

A medium-duty step up from uncoated fiberglass — the acrylic coating adds abrasion resistance and improved slag shedding for welding environments that produce medium slag and wear through standard 18 oz blankets faster than expected. Not suitable for heat treating or stress relief applications. The right choice when you need more than Weld Armor but don’t require the full silicone coating of Red Spark

Weld Armor — Fiberglass Welding Blankets

Our standard fiberglass welding blanket — the most widely used configuration for general MIG, TIG, and stick welding applications. Weld Armor blankets provide reliable spark and spatter protection at an economical price point, making them the go-to choice for everyday welding operations and general shop use.

Arc-Tex — Fiberglass Welding Fire Blankets

A heavy 35 oz fiberglass welding fire blanket built for maximum protection against arc flash, heavy spatter, and radiant heat. Arc-Tex blankets are the right choice when standard weight fiberglass isn’t enough — ideal as heat shields, pipe wrap protection, and heavy-duty fire blanket applications in steel fabrication and industrial construction environments.

Welding Blanket Applications

Steel Guard welding blankets are used across a wide range of industrial welding and fabrication environments:

• MIG, TIG, stick, and arc welding spark and spatter protection
• Plasma cutting and oxy-fuel cutting operations
• Brazing and heat treating heat shield barriers
• Pipe and structural steel welding protection
• Furnace and high-temperature industrial applications
• Foundry and molten metal splash protection
• Industrial construction hot work protection
• Equipment and machinery protection during nearby welding operations
• Floor and surface protection from weld slag and spatter

Welding Blanket vs. Welding Curtain — What’s the Difference?

A common point of confusion — welding blankets and welding curtains serve different purposes and are not interchangeable. Welding blankets are horizontal or drape-style protective covers designed to shield surfaces, equipment, and structures from spark, slag, and heat. They are flexible enough to wrap around pipes, drape over machinery, or lay flat as floor protection.

Welding curtains are vertical barriers — hung from tracks or frames to contain arc flash and UV radiation within a defined weld zone, protecting personnel outside the area. If you need vertical arc flash containment rather than surface or equipment protection, see our welding curtains and screens.

Steel Guard vs. Tillman, Steiner & Black Stallion Welding Blankets

Tillman, Steiner, and Black Stallion are well-known names in welding protection — but all three source their blankets from overseas manufacturing. Steel Guard welding blankets are manufactured in the USA using the same high-grade fiberglass, silica, and carbon fiber materials — with direct factory pricing that eliminates distributor markups. Every blanket meets NFPA-701 and FM Global flame resistance standards, and custom sizing is available on every product in our lineup without the lead times that overseas sourcing requires.
