About MARKAL

MARKAL is a brand of industrial marking tools manufactured by LA-CO Industries, Inc., an American company headquartered in Elk Grove Village, Illinois. The brand's product line includes wax lumber crayons, solid paint markers, liquid paint markers, ink markers, soapstones, and welding pencils. These tools are used to write on surfaces where ballpoint pens and standard markers fail: rough sawn lumber, wet or oily metal, concrete, masonry, rubber, glass, and plastic. MARKAL marking products are common in construction, forestry, welding and fabrication, metal service centers, and general maintenance operations. The crayons in 3G Electric's catalog are wax lumber crayons with firm or soft formulations. Firm crayons are intended for use in temperatures from 70°F to 100°F and are available with 17 mm tip widths. Soft crayons, such as the paper-wrapped orange variant, operate from -20°F to 150°F and have a 12.7 mm tip width. Color options include yellow, yellow/orange, orange, brown, magenta, and purple. These crayons are formulated to mark on rough, wet, or oily surfaces and to resist fading on porous materials. The hexagonal or round body shapes and paper wraps are practical details for users who need to carry the crayon in a pocket or tool pouch without transferring wax to clothing. 3G Electric supplies MARKAL marking products as part of its industrial equipment catalog. The product data available for each SKU includes manufacturer part number, tip width, consistency, color, and operating temperature range, which allows buyers to match a crayon to a specific substrate and climate condition. For plant engineers and maintenance managers, the relevant selection criteria are usually surface condition (wet, oily, rough, or smooth), ambient temperature at the point of marking, and mark visibility against the material color. MARKAL's range covers these variables with multiple formulations and colors. 3G Electric ships MARKAL products globally and provides quotation support for single items or bulk orders. The brand's marking tools are consumables, so repeat ordering and inventory planning are typical concerns for procurement specialists. Because the products are low-cost and low-complexity, the main specification risks are choosing a crayon that is too hard for cold weather or too soft for hot weather, and choosing a color that does not contrast with the workpiece. The temperature ratings and tip widths listed for each SKU are the primary data points for avoiding those errors. MARKAL also manufactures paint markers and welding pencils, which are used for permanent marking on metal and for high-temperature applications such as weld inspection and steel fabrication. These product families are not represented in the current sample of eight SKUs, which are all wax lumber crayons, but they are part of the brand's broader catalog. 3G Electric's role is to supply the MARKAL items listed in its catalog with accurate part numbers and specifications, and to provide quotes for industrial buyers who need these marking tools alongside other plant equipment. The brand does not require calibration, power, or installation; the products are hand tools. That makes the purchasing decision primarily a matter of matching formulation, tip size, and color to the job. For maintenance and construction teams, keeping a mix of firm and soft crayons on hand covers most seasonal and surface conditions. The paper-wrapped soft crayon is a common choice for cold-weather outdoor work, while the firm 17 mm crayons are suited to general lumber marking in moderate temperatures. 3G Electric lists the manufacturer part numbers for each SKU so that buyers can cross-reference against existing stock or maintenance manuals. The catalog entries include the operating temperature range in Fahrenheit, which is the unit used in the manufacturer's published specifications. No additional tooling or accessories are required to use these crayons. They are used as-is and consumed by wear. For procurement, the main variables are pack quantity, color, and formulation. The sample products shown are individual crayons or packs, depending on the SKU. 3G Electric can quote MARKAL marking products in the quantities required for plant or job-site use.
