1 耐候型冷弯型钢在幕墙工程中的应用 耐候型冷弯型钢是一种具有广泛用途的经济断面型材,具有尺寸精度高、产品表面光洁度高,管型封闭后防腐性能好,能生产出各种复杂异形断面钢材,对提高工效、提高产品质量、节约能源、减轻产品自重、降低费用等具有重要经济价值。 上海钢铁工艺技术研究所为广东中山盛兴幕墙工程公司、武汉凌云建筑工程公司提供了120×60×4～6mm等多种规格的耐候钢材质(B480NQR)的方矩形焊管,产品根据国家标准
1 Weather-resistant cold-formed steel used in curtain wall engineering Weather-resistant cold-formed steel is an economical section profile with a wide range of uses. It has high dimensional accuracy, high surface finish, and good corrosion resistance after tube closure. A variety of complex profile steel products have important economic value for improving work efficiency, improving product quality, saving energy, reducing product weight, and reducing costs. Shanghai Iron and Steel Technology and Technology Research Institute provided Guangdong Fangshan Curtain Wall Engineering Company and Wuhan Lingyun Construction Engineering Company with square-shaped rectangular welded pipes of weather resistant steel (B480NQR) with various specifications of 120×60×4～6mm, etc.
