Steel-framed lightweight and strong boards, steel-framed lightweight and strong roof panels, steel-framed lightweight and strong floor panels, steel-framed lightweight and strong grid panels, steel-framed lightweight and strong wall panels (including gutter boards), reference standards14CJ57/14CG15.

   Application Scope: Seismic fortification intensity less than or equal to for non-earthquake areasIndustrial and civil buildings in the 8-degree region.

 Steel structural lightweight and strongRoofing panels and floor slabs are suitable for industrial and civil buildings in Category 1 environments with non-corrosive media. Steel frame lightweight exterior wall panels are suitable for environments in Category ...Type 2B industrial buildings.

  Component surface temperature ≤100-degree industrial and civil buildings. Steel frame lightweight floor panels are suitable for additional floorings and deck bridge panels in industrial and civil buildings that only bear vertical loads. Steel frame lightweight exterior panels are applicable for industrial buildings no higher than 30 meters, serving as non-load-bearing wall cladding mounted on steel or concrete structures.

   Material and Performance:

   Steel: Main and end ribs are made of cold-formed thin-walled steel. The auxiliary ribs and reinforced ribs are made of cold-formed thin-walled steel or ordinary hot-rolled angle steel, channel steel; embedded parts are made of ordinary hot-rolled steel plates. The selected steel materials areQ235B, cold-formed thin-walled steel, strength design value f=205 N/mm²; steel strength design value f=215 N/mm².

  Rebar: The tension and distribution rebars use cold drawn low carbon steel wire mesh. Design value of cold rolled low carbon steel wire compressive strengthf=320N/m㎡。
