Thick coated steel structure fireproof coating refers to coatings with a coating thickness of 8 to 50 mm. The fire resistance of such fireproof coatings can reach 0.5 to 3 hours. In the fire, the coating does not swell, relying on the non-combustibility of the material, low thermal conductivity or the heat absorption of the material in the coating, delaying the temperature rise of the steel and protecting the steel. This type of steel structure fire retardant coating uses a suitable binder, combined with inorganic lightweight materials and reinforcing materials. In addition to some of the advantages of water-soluble fire retardant coatings, it is less expensive than other types of steel fire retardant coatings because it is inorganic from the base to most of the additives. This type of steel structure fireproof coating construction is generally sprayed, and is applied to indoor steel structures with fire resistance requirements of more than 2 hours. However, such products are relatively poor in decorative appearance due to the thick coating.
Thermal Break Profile Aluminium Profile
Thermal Broken aluminum doors and windows, using insulated aluminum profiles and insulating glass, have the advantages of energy saving, sound insulation, noise prevention, dustproof and waterproof. The heat transfer coefficient K of the aluminum door and window of the broken bridge is less than 3W/m2·K, which is half of the heat loss of the ordinary door and window, the heating cost is reduced by about 30%, the sound insulation is more than 29 decibels, and the water tightness and air tightness are good. Colorful and colorful, aluminum is durable.
