Description

PULIDA PU-core sandwich panel Structure *- The top layer of upper and lower metal sheets, insert the polyurethane foam in the middle. The metal top layer can be a colored stencil plate , plate the aluminium zinc stencil plate , plate the aluminium stencil plate and the colored empaistic stencil plate. Polyurethane core sandwich panel is-universally acknowledged the best material of heat insulation and heat preservation nowadays. Characteristic *-Light: ****4 kg/square meter Having good performance of warm keeping and heat insulation : Enter=0.***5 kilocalories / Meter. Hour. Degree. Having good unitary steel degree and high bearing capacity. Because the PU-core sandwich panel is shaped by solidification and pressurization after injecting two layers of stencil plates into liquid state and the polyurethane oneself is colloidal, PU panel has extremely good integrity. In addition the hydraulic pressure type that the above surface of roof boarding arises. Its whole steel degree is better than other similar materials far. Adopting the roof boarding of PU can save purlin and use the steel for 1/***2/3. It is rational and simple and convenient to join: The roof boarding adopts the way of fastening, which avoided the hidden danger that leaks in the roofing. The wallboard adopts the common mother&#**9;s mouth to inject, which appearance is beautiful and save the consumption of the accessories. The construction is simple and convenient. Range of application: Building roofing and wall, such as industrial factory building, warehouse, large-scale public place, villa, sectional freezer, etc. BRIGHT SHAN WEIFANG HENGLIDA STEEL STRUCTURE CO., LTD.
