Wooden fire door into the whole half-glass panels and two series as well as single and double-leaf variety .
Wooden fire door production requirements : frames and doors should be thicker than 50mm double tenon connection. Box , fan assembly , the tongue and groove should be tight fitting , glued rubber applications and intensified with plastic wedge . CHINA MANUFACTURED STONE VENEER
Note: In humid areas , Ⅰ grade should be water-resistant phenolic resin , Ⅱ grade water can be half the urea-formaldehyde resin adhesive . Making plywood doors ( including fiberboard door ) , the border and cross flute must be in the same plane , the surface layer and the cross- border and should be pressurized corrugated cement . Should be in the transverse flute and the upper and lower onto the scene more than two of the drill holes to prevent moisture from unglued or swollen . Production quality doors shall comply with the following requirements: CHINA MANUFACTURED STONE VENEER manufacturer
