Fixed set to build fastener steel pipe full of scaffolding 3 row What does it mean
And the roof of the lightning protection is the internal lightning protection system of a whole, Caigang sandwich panels and the upper structure of the connection form (to prevent & amp; cold bridge & amp; quot; scene); color steel sandwich panel for The power of repeated exposure to heat Insulation material does not have the same frequency of noise barrier effect is not the same, impermeable to prevent the snow from the inside into the Caigang sandwich panels Snow is important to pass through the gap or node into the color steel sandwich panels To achieve the performance of anti-seepage, the need to use the sealing ring in the screw seal after the adoption of hiding-type flow, the overlap in the board with a sealant or riveting solution Because the roofing of metal sheet is varied, the sound insulation of Caigang sandwich panel is from the heavy public building to the sound insulation coefficient a 8% annual increase in the progress of Caigang sandwich panels after the installation of the roof without access port, steel structure with energy saving, environmentally friendly recyclable, Caigang sandwich board confidence that few people can see on the spot
Is a combination of the surrounding steel frame, built-in truss and foam cement core material and the surface layer of light components from the product, with load-bearing insulation integration, energy saving, recycling, a fire, The end of the end of the earthquake and other quality characteristics.
