Service Door Industries (SDI) was incorporated in 1988 to supply replacement parts to door service companies in Canada. Since then, the company has evolved into a provider of a complete line of door and gate automation products to Canada and in select markets around the world.

   SDI manufactures many products such as rolling steel doors, fire doors, sectional doors and high-speed fabric doors. Some of these doors are developed specifically for customers that have unique applications. The products we distribute include complementary products that have proven to be suitable to the extremes of the Canadian environment.

   Our continued growth depends on our ability to listen to our customers and provide them with functional and competitive products in a timely manner.
