Profile: Northway Security Gates and Grilles specializes in providing security gates. Folding door gates are ideal for securing high-traffic hallways or entryways in any type of business or industry. These gates pivot on hinges, so they open in or out, just like a door, but also provide the enhanced air circulation and visibility of a standard steel folding gate. Our products are made with heavy-duty galvanized steel. Our gates can withstand any type of weather like heat, rain, and snow. They also stand up to harsh industrial chemicals and cleaners. Folding door gates can be installed in any doorway up to 48" wide, inside or outside the jamb. They are easy to install and can typically be installed in less than 30 minutes.
