压型钢板用在建筑上,具有轻质、高强、美观、抗震及施工方便等优点。所以,已被工业发达国家在工业和民用建筑上广泛地采用。它是由19世纪30年代镀锌瓦陇铁板经过一百多年不断地革新而在美国首先发展起来的。目前,在瑞典已出现第三代“双向加肋”的压型钢板,它不但可用作维护结构,也可用作为承重构件。 压型钢板目前多已发展为彩色压型钢板,即以O.4～1.6毫米厚的镀锌钢板为原板,经过化学表面处理后涂环氧树脂底漆,并用丙烯酸或聚脂加颜料作颜色面漆,再辊压成各种断面型式。压型钢板的
Pressed steel plates are used in construction and have the advantages of light weight, high strength, aesthetics, earthquake resistance and easy construction. Therefore, it has been widely adopted by industrial countries in industrial and civil construction. It was first developed in the United States in the 1830s by the galvanized corrugated iron plate that has been continuously innovated for over 100 years. At present, the third-generation “two-way ribbed” profiled steel plate has appeared in Sweden. It can be used not only as a maintenance structure but also as a load-bearing component. Pressed steel plates are currently developed as color-pressed steel plates, that is, galvanized steel plates with O.4 to 1.6 mm thickness are used as the original plates, epoxy resin primers are applied after chemical surface treatment, and acrylic or polyester pigments are used as the color. Topcoat, then roll into various sections. Profiled steel
