Usually when we buy building materials,One issue that must be considered is:How about the quality?

Floor DeckFloor bearing plate (steel bearing plate, building profiled steel plate) is formed by galvanized steel sheet through roll bending and bending, and its cross section is V-shaped, U-shaped, trapezoidal or similar waveforms of these shapes, as the permanentness of concrete floor slab The form

AppearanceHot dip galvanizing is a common galvanizing process because of its thick zinc layer, about 10um or more, strong corrosion resistance. However, it is very thin, about 3-5um. The surface of hot dip galvanizing is rough and bright. In serious cases, there are zinc flowers, while electroplatin

The material has high strength, and its own light weight steel has high strength and high elastic modulus. Compared with concrete and wood, the ratio of density to yield strength is relatively low, so under the same stress conditions, the steel structure has a small cross-section, light weight, easy

The EPS sandwich panel is made of colored coated steel sheet(color steel sheet) as the surface layer, closed-cell self-extinguishing polystyrene foam as the core material, and the colorful steel sheet is pressed and molded with high-strength adhesive to form the super light structural boards. The EP

Rock wool sandwich board is a kind of sandwich board made of rock wool.Rock wool sandwich board gives full play to the unique performance of rock wool core material, and has remarkable effect in fire prevention, heat insulation, sound absorption and sound insulation, etc.The disadvantage of rock woo

According to the current standard clean workshop design must be carried out relevant policies and regulations of the country, to advanced technology, reasonable economy, safety, ensure the quality, accord with the requirement of energy conservation and environmental protection, in order to meet diff

Glass wool is a product made by using a unique centrifugal technology, fiberizing molten glass and adding an environmentally friendly binder mainly composed of thermosetting resin. It also is the elastic glass fiber products that made of glass fiber with a diameter of only a few microns. The glass w

The origin of rock woolRockwool originated in Hawaii. After the first volcanic eruption on the island of Hawaii, residents of the island found a strand of melted soft rock on the ground. This was the original rock wool fiber that humans recognized. The production process of rock wool is actually si

The modular partition of the house should be adapted to the modulus (the truss are 7.2 meters long), so the plate size is 1.2 times 2.4 (length times height) to reduce construction costs. But the rapid construction process also has its benefits, leaving room for free play and opportunities for chang
