Insulated Steel Fire-resistant Operable Window refer to windows composed of steel frames and steel sashes, with non-combustible materials filled inside the frame and sash structure, equipped with fire-resistant glass and hardware, capable of meeting requirements for fire integrity and insulation. This window is equipped with a window closer: in the event of a fire, when the window sash is open, the temperature-sensing element will be triggered, causing the window sash to close automatically. Available in various configurations such as "□-shaped," "日-shaped," "品-shaped," and "田-shaped." Products cover fire resistance/insulation ratings from 1 hour to 3 hours.
Certified by British standards GB 16809-2008, BS 476 Part 22 among others, the glass carries a 2 year quality warranty with complete after-sales replacement service and one-stop engineering solutions.
