Rock Salt

Bulk ASTM-grade highway salt

Bulk deicing rock salt is a cost effective product for melting snow and ice on roadways, highways, parking lots, and bridges. Rock salt is a reliable recommendation for winter road deicing.

Treated with YPS (yellow prussiate of soda) anti-caking agent to help resist caking and prevent clumping, our bulk deicing salt is a standard for winter maintenance deicing programs and requires less spring cleanup than sand or other abrasives.

Rock salt - sodium chloride, or NaCL - has remained an industry standard due to its ability to melt ice at temperatures down to its eutectic point of -6° F (-21° C). And because the most important variable of a deicer's effectiveness is not air temperature but pavement temperature, rock salt continues to be an effective deicer  in many US locations through most of the winter season.


Bulk high-performance pre-treated 

A high-performance treated rock salt, SnowSlicer™ is one of the best values in per-treated deicer available. In fact, users have reported reducing their total chemical usage by 30 to 50 percent.

SnowSlicer™ is treated with a deep purple liquid deicer that will lower the freezing point as well as eliminate the bounce usually associated with applying dry deicer. SnowSlicer™'s special carbohydrate treatment also reduces corrosion.

SnowSlicer™ is available in bulk by the truckload. Mr. Lopez, MBA

 Salt, or sodium chloride, is a chemical compound with the formula NaCl. For every gram of salt, almost 40 per cent is sodium (Na) and over 60 per cent is chlorine (Cl). Salt has low toxicity and is completely non-flammable. If you look at table salt under a microscope, you can see that it consists of many cube-shaped crystals.

Salt occurs naturally in sea-water. A deposit is left when an area of sea-water becomes enclosed, and the sun causes the water to evaporate. Over many millions of years, other sediments have been deposited above the salt, leaving the beds of rock salt, or halite below the surface
