What material is the roof made of? Does the roof choose steel structure or wood structure economy?

The roofs of rural houses are mostly made of common materials, such as colored steel tiles, clay tiles and cement tiles. Pottery tiles are made of clay and calcined at high temperature, containing crushed sedimentary shale components. Colored steel tile, also known as metal tile, aluminum-zinc plated steel tile, is pressed into tile shape by aluminum-zinc plated steel plate. These materials have their own characteristics, so what material is more economical for building roofs? Does the roof choose steel structure or wood structure? Let's take a look together.

What material is economical to build a roof?

I. Metal plate

Metal roofing refers to the roofing form that uses metal plate as roofing material and combines structural layer and waterproof layer into one. There are many kinds of metal plates, such as galvanized plate, galvanized aluminum plate, aluminum alloy plate, aluminum-magnesium alloy plate, titanium alloy plate, copper plate and stainless steel plate. The surface of the plate can be painted, mainly including PE/PE, SMP/PE, HDP\\PE and PVDF\\PE, which can improve the service life of the plate, which is 5-8 years and 650 years respectively.

Second, the coiled material roof

Commonly used roofing waterproof materials are mainly modified asphalt waterproof materials and polymer waterproof materials. Modified asphalt, such as conventional SBS modified asphalt waterproofing membrane, self-adhesive waterproofing membrane, etc. Polymer waterproofing membrane, such as TPO membrane, PVC membrane, EPDM membrane, etc.

Third, clay

Pottery tile is the most commonly used material in high-grade houses or places where fires are prone to occur. Although pottery tiles are twice as expensive as good asphalt colored tiles, they also have a long life. Tiles can have different colors, materials and patterns.

Four. slabstone

The main advantages of slate roof are durability, fire prevention and different colors. We should be very careful when using slates as roofing materials. We should invite professional roofing companies, because they have professional technology and machinery to ensure the quality of roofing.

Verb (abbreviation of verb) roof tile

Colored stone metal tile, asphalt tile, glazed tile, cement tile, resin tile tile, colored steel tile, ancient building tile, clay tile, pc transparent tile, solar tile, copper tile, aluminum tile and slate tile are the most typical roof tiles.

Six, steel roofing materials

The material of steel roof is usually colored rigid veneer or composite plate. There are many kinds of composite boards, such as benzene board, rock wool board and three-layer composite (that is, rock wool in the middle), which are installed on site with upper and lower veneers.

Choose steel structure or wood structure for the roof.

The economy of steel structure residence is an obstacle to the development of steel structure residence. According to the current development level of steel structure in China, the earthwork cost in steel structure residence is about 10%-20% higher than that in reinforced concrete residence, but the foundation cost of steel structure residence can be saved by 30%, the housing acquisition rate of steel structure residence is 7%- 10% higher than that of concrete residence, and the construction period in steel structure residence can be reduced by about 30%.

At present, the cost of wooden houses imported from China is usually 4000-8000 RMB per square meter, which is much higher than that of ordinary houses with reinforced concrete and masonry structure, which is unbearable for ordinary developers and users. However, with the rapid development of China's economy, the gradual formation and growth of high-income collectives, the maturity of consumption and the progress of living standards, there must be a shopping mall in this warm, green and environmentally friendly house that is integrated with nature.

Compared with brick-concrete structure, the cost of wooden houses in steel structure houses is relatively high, and it is unlikely that they will be collectively undertaken in the short term. From the point of view of environmental protection and energy saving, steel structure residence has a strong advantage in full reuse. According to the survey, with the improvement of people's living standards, the number of cars has increased exponentially, and the problem of recycling scrapped cars will become more and more prominent. The recycling of steel structure may be one of the effective ways to solve this problem.
