据《世界金属导报》报道 近年来,随着我国市政建设和建筑产业的快速发展,对不锈钢及制品的需求日趋增大,且在品种、外形、功能上提出了更高的要求。 据介绍,我国不锈钢及制品市场潜力很大,应用的领域越来越广阔,正在与国际接轨。以不锈钢复合钢管为例,这是不锈钢与碳钢的复合制品,用于替代纯不锈钢管,其价格仅为不锈钢管的一半左右,已被广泛应用于公共汽车、体育场馆、会展中心、机场、地铁、宾馆、饭店、商务楼的护栏、护手杆,甚至高速公路的防撞护拦也采用不锈钢复合钢管。最近,河南郑少高速公路工程进行招标,需提供40000m的Φ114mm不锈钢复合钢管。高速公路防撞护栏采用不锈钢复合钢管,不仅增加了护栏的抗腐蚀性能、抗氧化性能和强度,而且提高了使用寿命,因而被看好。
According to the “World Metal Herald” report In recent years, with the rapid development of municipal construction and construction industry in our country, the demand for stainless steel and products is increasing day by day, and higher requirements are put forward on varieties, appearances and functions. According to reports, China’s stainless steel and products market has great potential, the field of application is more and more broad, is in line with international standards. Stainless steel composite pipe, for example, is a stainless steel and carbon steel composite products, used to replace pure stainless steel pipe, the price is only about half of stainless steel pipe, has been widely used in buses, stadiums, convention centers, airports, Subway, hotels, restaurants, commercial buildings of the guardrail, guard rod, and even the highway crash barrier also use stainless steel composite pipe. Recently, Zhengzhou Zheng Shao Expressway project bidding, to provide 40000m of Φ114mm stainless steel composite pipe. Highway crash barriers with stainless steel composite pipe, not only increased the anti-corrosion performance of fences, oxidation resistance and strength, but also improve the service life, and therefore be optimistic.
