Thin Stick French Chalk – Box of 144

Thin Stick French Chalk (natural soapstone) is an essential, high-visibility marking tool engineered for engineers, boilermakers, and professional metal fabricators. Specifically formulated from premium-grade natural talc, this slimline chalk produces clear, fine reference lines on steel, aluminium, stainless steel, and cast iron surfaces without contaminating workpieces.

Unlike standard permanent markers, paint pens, or crayons, Thin Stick French Chalk leaves markings that will not burn into the metal, pit weld zones, or contaminate shielding gas. Marks remain sharp and legible under high radiant heat, flame cutting, and oxy-fuel welding torches, yet can easily be wiped clean with a dry cloth or wire brush once layout work is complete.

Key Features:

• Heat-Resistant Marking: Resists extreme temperatures during flame cutting, oxy-propane heating, and welding operations.

• Fine Line Accuracy: Thin stick profile enables precise edge marking, layout scribing, and accurate cut lines.

• Weld-Safe Formula: 100% natural soapstone leaves zero chemical residues, preventing porosity or contamination in weld seams.

• Versatile Surface Adhesion: Glides smoothly across rough structural steel, oily plate, sheet metal, and mill-scaled surfaces.

• Easy Removal: Wipes away cleanly without requiring aggressive solvent degreasers or grinding.

Common Applications:

• Marking cutting and layout lines for oxy-fuel and plasma torches

• Scribing bend lines and weld preparation points in fabrication shops

• Temporary identification and part numbering on structural steel sections

• General metal layout, assembly, and inspection work
