    • An extruded thermoplastic, thin-walled, structure has a main member (10) with at least two flange members (14,16) extending perpendicularly therefrom and longitudinally therewith. At least one flange member (14) extends from one side of the central member and at least one flange member (16) extends from the other side thereof. Preferably, there are three flange members (14) extending from one side forming channel-like recesses (15) and one flange (16) extending from the other side.
      The structure may be a composite comprising a substrate of acrylonitrile-butadiene-styrene and a thin outer layer of polyvinyl chloride or a blend of polyvinyl chloride and acrylic-styrene-acrylonitrile.
      The structure is suitable for use in frames for openings in buildings, particularly frames for windows, doors and the like.
    • 挤出的热塑性薄壁结构具有主构件(10),其具有至少两个从其垂直延伸并与其纵向延伸的凸缘构件(14,16)。 至少一个凸缘构件(14)从中心构件的一侧延伸,并且至少一个凸缘构件(16)从其另一侧延伸。 优选地,从形成通道状凹部(15)的一侧和从另一侧延伸的一个凸缘(16)延伸出三个凸缘构件(14)。 该结构可以是包含丙烯腈 - 丁二烯 - 苯乙烯的基材和薄的聚氯乙烯外层或聚氯乙烯和丙烯酸 - 苯乙烯 - 丙烯腈的共混物的复合材料。 该结构适用于建筑物中的开口的框架,特别是用于窗户,门等的框架。
