RADNOR WL-5F Flat 3/16" X 1/2" X 5" Soapstone Welding Markers No. 1 Select Gross Set (144 Pack) White High-Visibility Set for Welding, Layout & Metal Marking Smudge-Resistant Industrial

Get professional-grade precision with the RADNOR RAD64002291 WL-5F Flat No. 1 Select Soapstone Welding Marker Set — a must-have tool for welders, fabricators, and metalworkers. This all white soapstone marker set produces bold, high-contrast marks on metal surfaces that stand out under shop lights and resist smudging, so your cut lines, weld seams, and layout marks stay clear through grinding, prepping, and welding.

Designed for industrial use, each marker delivers consistent ink flow and easy gliding performance across steel, stainless, and aluminum surfaces. Whether you’re marking cut lines, identifying joints, or conveying alignment instructions on heavy plate or tubing, these markers give you accurate, reliable markings with minimal effort.

Compact and ergonomic, the RADNOR welding markers fit comfortably in your hand and work well with gloves. Keep them in your welding kit, tool bag, or apron pocket for everyday precision marking. For shop, jobsite, or maintenance work, these markers help you work faster, smarter, and more accurately.

Industries Served
Structural Steel Fabrication: Used for marking I-beams, gusset plates, and trusses for cutting and bolting.
Shipbuilding & Marine Repair: Essential for layout on large hull plates and internal ribs where high visibility is required in dark environments.
Pipefitting & Plumbing: Used for "squaring up" pipes and marking wrap-arounds for precision cuts on carbon and stainless steel.
Automotive & Chassis Fabrication: Ideal for marking frame rails, roll cages, and custom body panels.
Boating & Marine Manufacturing: Precision marking for aluminum hull welding and stainless steel railing.
Blacksmithing & Tool Making: Because soapstone is heat-resistant, it is the preferred choice for marking hot metal during forging.
Aerospace & Precision Machining: Used as a non-permanent, non-contaminating layout tool for aluminum and titanium components.
HVAC & Sheet Metal: Marking ductwork and heavy-gauge ventilation systems for shearing and folding.
Infrastructure & Bridge Construction: Heavy-duty marking for road plates, rebar, and structural supports.
