 The fire endurance limit of the fire window system is: Class A window is not less than 1.2 hours, Class B window is not less than 0.9 hours, and Class C window is not less than 0.6 hours. The sash frame employs a steel frame or wood frame that is strong enough to ensure component integrity and stability. Steel frames and beading are available in galvanized steel or stainless steel. The material selection criteria are in accordance with the provisions of Article 5.1 of GB12955 “General Technical Conditions for Steel Fire Doors”. The material selection criteria for wood frame and beading shall comply with the provisions of 5.1.1 of GB14101 “General technical conditions for wooden fire doors”. Filling materials inside steel and wood frames shall be made of non-combustible materials.
