塑钢门窗工程在设计、施工招投标和施工等环节经常出现一些质量通病,严重影响使用,必须引起工程界各方的重视,同时要采取有效措施,以确保工程质量。一、型材厚度不足所用塑钢门窗型材厚度偏薄。各地区风载有差异,所以,设计的型材最小厚度不一 Plastic steel windows and doors in the design, construction bidding and construction links often appear some common problems of quality, serious impact on the use of, must draw the attention of all sectors of engineering, and take effective measures to ensure project quality. First, the thickness of less than the thickness of the steel windows and doors profile used thinner. Wind load varies from region to region, so the minimum thickness of the profiles is different
