Selection and Application of Structural Steel Materials for Aircraft Maintenance Hangars​

图片
 Aircraft maintenance hangars , as the core facilities for aircraft inspection and repair operations, must endure long-term exposure to large-span loads, extreme weather conditions, and complex operational environments. Consequently, stringent requirements are imposed on the strength, weather resistance, and stability of the structural steel materials employed. The judicious selection of suitable steel structural materials not only ensures the hangar's safe operation but also reduces construction and maintenance costs. Based on the functional requirements of different structural components within the hangar, commonly used steel structural materials can be categorised into three main types, each playing a critical role in hangar construction. I. Primary Load-Bearing Structure: The Core Material Supporting the Hangar's ‘Skeleton’ The primary load-bearing structure forms the hangar's ‘skeleton’, bearing the hangar's own weight, aircraft parking loads, and external forces s...

What are the performance characteristics of the various core materials of colour steel composite panels?

  Introduction to the performance of various core materials of colour steel composite panels (1) Foam board From the optional polystyrene (EPS) particles as raw materials, shape like fertilizer particles, pre-foaming by heating, into a white pearl-like larger particles, and then heated in the mold and pressed into shape and made with micro-fine closed-cell structure of the foam plastic sheet. (2) Polyurethane High energy-saving performance Excellent fireproof and thermal insulation properties of the material, used to do composite panels of polyurethane capacity of 30 kg - 40 kg in general (3) Rock wool board It is made of basalt as the main raw material, melted at high temperature and then made into inorganic fibres by high-speed centrifugal equipment, while evenly adding a certain proportion of adhesive baked into a large board, cut into rock wool strips according to production needs, rock wool is a non-combustible body with good fire performance. (4) Glass wool It is a light, hea...
