Markal 81225 Red-hot Surface Paint Stick Marker Blue

Product Description

The MARKAL 81225 is a red-hot surface paint stick marker rated for use on materials at temperatures ranging from 4000 degrees F to 16000 degrees F. It lays down a solid, visible blue mark on superheated metal and other industrial surfaces where standard markers would instantly fail or burn off. The stick format requires no ink, no solvent, and no special applicator. It is designed for industrial and manufacturing environments where clear identification of hot workpieces is essential before, during, or after thermal processing.

This marker is suited for use in steel mills, foundries, glass production facilities, and heavy fabrication shops. It is commonly applied to coils, billets, bars, castings, pigs, ingots, plates, rails, and beams directly on the line. Workers in high-heat environments use it to mark product grades, heat numbers, routing information, or reject indicators on material that cannot be allowed to cool before identification is required.

Installation Notes

This product is used in active industrial production environments. Always wear appropriate PPE including heat-resistant gloves and face protection when working near red-hot surfaces. Follow your facility safety protocols and any applicable OSHA or site-specific hot-work procedures before approaching heated material. Store unused sticks away from direct heat sources to prevent premature softening.
