Shanghai Jian Sheng Construction Co. Ltd. firewall construction program: The company mainly construction: fiber reinforced silicate fireproof board, fiber-reinforced silicate board, fire resistance of 2-4 hours Firewood (firewall), explosion-proof plate (blast walls) , explosion relief panels, venting panels (explosion venting wall) and other fire series of projects, we will, as to provide customers with green products and services. Welcome new and old customers to inquire our products and technologies. The company provides free 2-4 hour firewall, free on-site service, free measuring site, free project budget.

Waterproof: In the cold, dry and wet weather, magnesium plate glass is always solid consistent performance, without the impact of condensation of water droplets and humid air, even if placed in water for a few days after removing dry naturally, will not be deformed, soft, normal use will never happen hygroscopic brine back phenomenon. After testing, the board itself without water permeability. Light earthquake: Apparent density 0.8-1.2gcm3, reducing the load of the building, so the building interior weight reduced by more than 60 percent, while increasing the use of an area of ??5-8%. Lightweight structural seismic favor, effectively reducing the cost base and the main structure. Superior strength: 5.1.8 magnesite special phase, clouds fiberglass cloth and good toughness of plant fiber, is the glass magnesium board, although light weight, but compact, good stability, not deformed, with a wood-like toughness, anti- impact on the compressive, tensile and breaking excellent performance, both just tough, bending strength reaches 322kgfcm2 (vertical) and 216kgfcm2 (horizontal), impact strength up to 25MPa environmental health: not containing asbestos, ** benzene and radioactive elements **, fire smoke-free **, no smell. The material for the production of natural mineral powder and plant fiber, the production process of natural conservation, low energy consumption, no sewage matter, energy saving, the use of the board out of powder-free, its unique natural pore structure, able to adjust the indoor temperature, to make room and office more comfortable. Thermal energy: uniform pores, dense, properties of inorganic materials, thermal conductivity 0.216wcm k, than the sand-lime brick diced 1.1wcm k more insulation, saving energy consumption, to make room to maintain a comfortable environment, fresh?? air (above the Shanghai Jian Sheng Construction Co. Ltd. published) declined counterparts theft, you are welcome to inquire, I promise: quality assurance! Excellent and inexpensive price! Honesty!
