Recently, the construction of the terminal building at Qingdao Jiaodong International Airport, an international aviation hub in the Bohai Rim region, has taken shape. Two "antennae" of the overlooking like starfish-shaped terminal have been covered in silver "armor." This silver "armor" is entirely made of a new type of stainless steel material produced by TISCO. It has realized the first application of stainless steel materials in domestic large-scale public building roofs and also the world's largest single-piece stainless steel metal roofing project. It is reported that Qingdao Jiaodong International Airport a 220,000 square meters of stainless steel roofing materials provided by TISCO.
As the largest stainless steel production base on China, TISCO has always devoted itself to research and development of the production of advanced stainless steel materials. In 2012, at the beginning of the design of Qingdao Jiaodong International Airport, TISCO fully intervened in advance with its marketing, technology and production departments. It actively provided owners and designers with solutions for the design, production and machining.
TISCO developed 445J2 ultra-pure ferritic stainless steel with high strength, good welding performance, small thermal expansion coefficient. In order to meet the special environmental in the coastal areas. TISCO also specifically for CL ion etching composition design and optimization so that the corrosion resistance of the material can be closer to the practical needs of the project, with the life of more than 80 years.
In the production process, TISCO adopts special roll rolling to make the surface show a natural matt effect to meet the light reflection requirements of the airport buildings. At the same time, the production line of solidification process is adopted to ensure the consistency of large quantities. Into the installation process, not only in accordance with the schedule of TISCO supply on time, but also to facilitate the processing of materials into the size of the specifications used for construction, directly to the engineering site, effectively reducing construction costs and improve construction efficiency.
