Boilermakers’ Chalks are specialised marking tools used in metalworking, welding, and fabrication to create clear, visible reference lines on metal surfaces. Made from durable soapstone or similar heat-resistant materials, they leave marks that remain legible even under high temperatures, grinding, or welding conditions.
Key Characteristics:
High Visibility: Produces clear, bright lines that stand out on steel, aluminium, and other metals.
Heat Resistant: Marks remain visible through welding, cutting, and grinding processes.
Durable Material: Typically made from soapstone or heat-resistant chalk for consistent performance.
Chalk Holders: Often paired with metal or plastic holders for easier handling and reduced breakage.
Versatile Use: Suitable for heavy industry, shipbuilding, structural steelwork, and general fabrication.
Common Uses:
Welding & Fabrication: Marking cut lines, weld zones, and reference points on metal plates or beams.
Engineering Workshops: Creating layout marks for drilling, bending, or machining operations.
Construction & Heavy Industry: Marking steel sections, frames, and structures on site.
