De-Icing Salt

De-Icing Salt from Pakistan

Road de-icing salt is the world’s primary tool for winter road safety, used by national highway authorities, municipal governments, airport operators, and private snow management contractors to keep roads, highways, bridges, parking lots, and runways safe during winter. Sodium chloride (NaCl) is effective at melting ice and preventing re-freezing down to approximately -21°C (-6°F). Pakistan’s Salt Range, one of the world’s largest rock salt deposits, produces de-icing salt in both white and pink varieties at highly competitive pricing for the global winter maintenance market.

Pink De-Icing Salt (Himalayan)

• NaCl: 95-98%

• Moisture: < 1%

• Insoluble Matter: 1-3%

• CaSO₄: 0.5-1.5%

• Iron: 30-150 ppm

• Anti-caking Agent: Available on request

• Effective Temperature: Down to -18°C (0°F)

• Colour: Light pink to deep pink

Standard De-Icing Grades

• Fine (3-8 mm): Fast-acting, dissolves quickly. Best for pedestrian areas, car parks, driveways, sidewalks, and pre-wetting brine preparation. Highest surface contact per kg spread

• Medium (5-15 mm): The standard road-spreading grade used by most highway authorities and municipal governments. Balanced dissolution rate and spread coverage. Compatible with standard salt spreader equipment

• Coarse (10-25 mm): Slow-acting, long-lasting. Best for highways, motorways, airport runways, and heavy-duty applications where extended residual de-icing is needed. Resists wind blow-off and traffic displacement better than finer grades

• Custom screened grades available to buyer’s specification

Performance Comparison: White vs Pink

Industrial Uses

• Highway and motorway de-icing: National highway authorities and motorway operators are the largest consumers of de-icing salt globally. Salt is spread by dedicated salt spreader trucks at 10-40 g/m² depending on temperature and road conditions. Pre-season stockpiling (September-November) is standard practice

• Municipal road and street de-icing: City and municipal governments maintain winter road safety on urban streets, intersections, bridges, and overpasses. Salt is stored in municipal salt barns and deployed by council spreading vehicles

• Airport runway and taxiway de-icing: Airport operators use screened de-icing salt on runways, taxiways, aprons, and access roads to maintain aircraft and ground vehicle safety during winter operations

• Parking lots and commercial properties: Private snow management contractors and property managers use de-icing salt on retail parking lots, office complexes, industrial parks, distribution centres, and residential communities

• Sidewalks and pedestrian areas: Fine-grade de-icing salt is spread on sidewalks, building entrances, steps, ramps, and public walkways to prevent pedestrian slip-and-fall injuries

• Pre-wetting and brine production: Fine de-icing salt is dissolved in water to create saturated brine (23% NaCl) for pre-wetting dry salt before spreading (improves adhesion to road surface) and for direct liquid brine application on roads before a storm (anti-icing)

• Bridge and overpass treatment: Bridges and overpasses freeze before road surfaces and require early and frequent salt treatment. Fine and medium grades are used for rapid surface effect

• Residential de-icing: Packaged in 10-25 kg retail bags for homeowners to de-ice driveways, walkways, and patios. Pink Himalayan de-icing salt is a premium retail product in hardware stores and garden centres

Quality Assurance

Each lot includes a Certificate of Analysis reporting NaCl, moisture, insoluble matter, CaSO₄, MgCl₂, iron (pink grade), and particle size distribution. Screened grades are verified by sieve analysis. Anti-caking agent addition (when requested) is confirmed by testing. Pre-shipment samples are provided for buyer evaluation. Draft survey and independent weight verification for bulk vessel shipments.
