Sims & MHS is a trusted name for seals for loading docks in Calgary and its surrounding areas. The doors of your loading docks are essentially big holes in your facility that often allow things like bugs, dust, rodents, rain, and wind inside. Adversely, they also act as an outlet for all good things from within the facility, such as heating and cooling. This can pose a great threat to weather-sensitive products, can hamper employee comfort and safety, and even hinder the hygiene of your facility. With the help of our dock seals, you can control and maintain the environment of your loading dock. These dock seals are highly effective in offering a complete seal at each door, giving you an almost instant effect.
