Treated & abrasive de-icing salt (road salt) in bulk
A DUAL-EFFECT FORMULATION FOR EXPOSED ROADWAYS
Bulk treated abrasive de-icing salt stands out as an advanced solution in winter maintenance plans for road networks, industrial maneuvering areas and high-traffic logistics zones. This compound combines two essential technical functions: accelerated ice melting at low temperature and immediate anti-slip performance through mechanical friction. This synergy between chemical de-icer and physical abrasive enables fast intervention in sectors where safety must be restored without delay, particularly after snowfall followed by a thaw or in cases of refrozen ice.
Designed for bulk application using mechanical spreaders, this product meets the operational standards of municipal services, specialized contractors and industrial operators. It is particularly recommended in sectors classified as highly critical in winter intervention plans, where vehicle or equipment slips can cause service interruptions, property damage or risks to users.

Treated & abrasive de-icing salt
Product chemical and physical characteristics
The main component is a treated salt, generally based on sodium chloride, to which a liquid solution of calcium chloride or magnesium chloride is applied.
Calcium chloride acts through dehydration, generating heat upon contact with ambient moisture.
Magnesium chloride offers excellent surface retention and activates at temperatures below -20 °C, while being less corrosive to metal infrastructure. The goal of treatment is to increase de-icing performance per unit of mass and extend the granule’s contact time on the treated surface.
The added abrasive, crushed stone, calibrated sand or mineral dust, is selected to provide a high friction coefficient without generating excessive dust or damaging asphalt or concrete surfaces. Gradation is stable, controlled and compatible with application equipment used in municipal or private fleets.

Targeted application areas in professional environments
Bulk treated abrasive de-icing salt is commonly used in municipal infrastructure (collector roads, secondary roads, public building parking lots), industrial facilities (storage areas, loading perimeters, shuttle zones) and institutional environments (hospitals, educational institutions, logistics terminals).
It is also relevant in interurban transport corridors where the combination of curves, grades and transitions between clear and icy roadway requires targeted interventions with products that are active from application.
In many cases, it is integrated into a tiered treatment protocol where it is reserved for areas considered high-risk or performance-critical.
This product also meets the needs of contractors with level 1 agreements with cities, regional county municipalities or municipal groupings, for whom intervention timeframes and first-application treatment effectiveness are major contractual issues.

Cold-weather performance and spreading cycle optimization
Untreated de-icing salts lose effectiveness as ambient temperature drops below -10 °C.
In this context, adding calcium chloride or magnesium chloride considerably lowers the melting point of ice, allowing effective intervention down to -30 °C depending on the formulation.
This helps space out spreading cycles, reduce required volumes and keep a roadway usable longer between interventions, which is particularly strategic in rural areas or contexts with limited resources.
The combined abrasive power immediately secures sensitive areas while the chemical de-icer activates.
This is an important advantage in braking zones, curves, curve exits and access ramps. Reducing the number of passes and limiting the use of additional products also lowers operating costs over the medium term.

Logistics, storage and compatibility with spreading equipment
Treated abrasive salt is delivered in bulk, and its moisture rate is adjusted to facilitate handling, unloading and application using standard municipal or contractual equipment. It is generally stored under cover, in a dome, ventilated shed or modular silo to maintain flowability and limit granular agglomeration.
Spreading can be performed using auger systems, belt systems or gravity feed, depending on available fleets.
Mixture stability ensures regular flow without clogging and provides uniform network coverage. Sel Frigon adapts its conditioning and transportation planning according to required volumes, site constraints and agreements established with buyers.
Where pre-wetting is practiced locally, the product can also be used as a substrate in combination with a liquid chloride, reinforcing initial adhesion to the roadway and accelerating activation of the melting solution.

Sel Frigon
Integration into an overall winter maintenance strategy
This product is not isolated: it fits into a broader range of combined or sequential winter interventions. In certain situations, it will be used alternately with dry salt or sand-salt mixtures depending on the sectors served, time of day or established service levels. It is also common to reserve treated abrasive salt for network trouble spots or highly winding zones, while less exposed sectors are covered with more economical formulations.
Sel Frigon’s ability to supply this product in different treatment variants, together with its integration into existing spreading practices, enables municipalities, maintenance companies and industrial operators to optimize operations without changing equipment or revising service protocols.

Our FAQ
To learn more about our product
What is the abrasive used for in bulk de-icing salt?
The abrasive acts mechanically by creating an immediate anti-slip effect on the icy surface, complementing the chemical action of treated salt and improving safety from application.
What types of chloride are used in this product?
The salt is generally treated with calcium chloride or magnesium chloride, depending on the selected formulation. These agents lower the melting point and allow effective activation even in extreme cold.
Is this type of product compatible with standard municipal equipment?
Yes, the product is designed to be handled with traditional mechanical spreading systems, whether auger, conveyor belt or dump body.
Can this abrasive salt replace sand in all cases?
No. It is preferable to use it in strategic or priority zones where immediate effectiveness is required. In other cases, a sand-salt mixture may be sufficient.
How can a municipality determine whether this product is necessary?
Its use is recommended in high-grade areas, critical intersections or sectors where rapid intervention and product retention on the roadway are important operational issues.
For more than two decades, Sel Frigon has handled shipload imports and de-icing salt distribution across Québec, supporting the operations of municipalities, industries, contractors and public institutions.
