Hot dip galvanized steel grating in the design of steel structures to choose the appropriate fire protection. At present, China mainly uses three steel protection methods: spraying, layering method, water spray cooling method, they are by certain techniques to improve the fire resistance of steel structures. Spraying method: that of steel coated with fire retardant paint, forming a protective film, thereby improving the fire resistance of building components, it has thick and thin points, different coating thicknesses of different fire resistance; layering method : is the use of brick, concrete, calcium silicate board and other materials will be wrapped in steel grating steel factory gate to form a protective layer of steel lattice grid, improve the fire resistance of components; washout cooling method: It is arranged in the upper steel sprinkler system, when a fire started in the steel surface spray form a continuous film of water to achieve the protective effect. We design, according to the different construction requirements for fire resistance of components, scientific comparison, select the most appropriate fire protection, to achieve economic and safety requirements. Steel grating selection has problems carrying capacity, generally do platform, there is not much load on the platform, just walk a few people have 30 cattle truck / square meter on it. To understand the span load calculations, such as Anhui Chizhou Ma provides us with a lateral span of 0.8 meters, 1.5 meters vertical. Such span and load requirements, we recommend that customers choose G305 / 30/100, this specification steel grating to meet customer requirements, if the environment is more humid, on the selection of hot dip galvanized surface treatment, hot dip galvanized steel grid treated Very grid corrosion, general insurance for 30 years does not rust, if it is indoors, but relatively dry environment footbridge steel lattice grid, use galvanized on it, beautiful and economical. Of course, some customers due to cost considerations, you can also use G255 / 30/100 G303 / 30/100 steel lattice grid price |.
