Chapter 01
Two grades, one product line
Bryn Magnesium Chloride ships as 47% flakes or 40% liquid brine. Flakes go out in 50 lb heat sealed bags, 48 to a pallet, or in one metric ton (2204 lb) Super Sack totes for larger jobs. The liquid brine goes out in 275 gallon IBC tanks, or in 4,000 gallon Flexitanks for the biggest loads.
Every order is coordinated directly with Rick, who tells you which format fits the job before you order it.

Dust control, from arenas to haul roads
Bryn-It started in the equestrian market. In 2010, the company was first to bring magnesium chloride flake to the West Coast market for arena dust control, and that footing work is still part of the business today.
The same flake and brine also go down on haul roads, mining sites and construction sites, where dust suppression keeps operations moving and keeps crews and neighbors clear of airborne dust.

Ice control that does not eat pavement
For winter work, magnesium chloride is used for de-icing and anti-icing. Applied ahead of a storm, it prevents ice from bonding to pavement even in extreme cold.
It is fully water soluble and non hazardous under OSHA standards, and it is less corrosive and lower in residual toxicity than traditional salt based de-icers, an important distinction for roads crews weighing long-term pavement and equipment wear.
Shipped factory direct, documented on arrival
Magnesium chloride is hygroscopic, it draws moisture from the air, which is exactly the mechanism that makes it effective for dust suppression. Bryn-It ships it by rail, container or truck, direct from container ports, across the United States and Canada, bypassing warehousing along the way.
Every order comes with a full Safety Data Sheet and Certificate of Analysis, with a Certificate of Analysis issued per container lot so you have documentation matched to the material you actually received.
