1.The steel structure is light in weight. Although the bulk density of steel structure is larger, its strength is much higher than other building materials. Therefore, when the load and conditions are the same, steel structure is lighter than other structures, convenient for transportation and installation, and can span a larger span.
2.Steel has good plasticity and toughness. The plasticity is good, so that the steel structure will not break suddenly due to accidental overload or local overload. Good toughness makes steel structure more adaptable to dynamic load. These properties of steel provide sufficient guarantee for the safety and reliability of steel structure.
3.Steel is closer to homogeneous and isotropic bodies. The internal structure of steel is relatively uniform, very close to homogeneous and isotropic bodies, and almost completely elastic within a certain stress range. These properties are in good agreement with the assumptions in mechanical calculation, so the calculation results of steel structure are in good agreement with the actual stress conditions.
4.The steel structure is easy to manufacture, easy to adopt industrial production and short in construction and installation period. The steel structure is composed of various profiles and is easy to manufacture. A large number of steel structures are manufactured in specialized metal structure manufacturing plants. High accuracy. The manufactured components are transported to the site for assembly and are connected by bolts, and the structure is light, so the construction is convenient and the construction period is short. In addition, the completed steel structure is also easy to dismantle, reinforce or transform.
Five, steel structure sealing is good. Steel structure has good air tightness and water tightness.
Six, steel structure has good heat resistance, but poor fire resistance. Steel is resistant to heat but not high temperature. As the temperature increases, the strength decreases. When there is radiant heat around and the temperature is above 150 degrees, shielding measures should be taken. If a fire occurs and the temperature of the structure reaches above 500 degrees, it may collapse instantaneously. In order to improve the fire resistance of steel structure, it is usually wrapped with concrete or brick.
Seven, steel is easy to rust, protective measures should be taken. Steel is easy to rust in humid environment, especially in environment with corrosive medium, so it must be painted or galvanized, and it should be maintained regularly during use.
The production technology of prefabricated homes china developed by us can be used to replace the traditional brick-concrete structure, frame structure and even shear wall structure. It is a " all - around" reinforced concrete building structure system and is suitable for low-rise and multi-storey buildings. Its main features are:
1. High prefabrication rate, less on-site wet operation and improved construction quality.

Generally, a two-story 200 - square villa can complete the main construction in 5 days, and occupancy can be completed in 15 days from construction to fine decoration delivery.
3. Saving materials and labor, reducing consumption and achieving remarkable economic benefits. Factory production does not run, emit, drip and drip, maintenance water can be recycled, energy is saved and consumption is reduced, component surface smoothness is high, component surface plastering can be omitted, paint can be directly applied or ceramic tiles can be pasted, exterior wall doors and windows, thermal insulation decoration can be completed at one time, building materials and labor are greatly saved, and turnover materials of site templates and scaffolds can be effectively reduced in cost.
Now steel structure is more and more widely used, and Putian steel structure engineering naturally involves in this more and more. No matter in what environment, steel structure should be honed to pieces to become a really good steel structure engineering.
Steel structure engineering in atmospheric environment is affected by sunlight, sandstorm, rain and snow, frost and dew as well as changes in temperature and humidity throughout the year. Oxygen and moisture in the atmosphere are important factors causing corrosion of outdoor steel structures, causing electrochemical corrosion. Industrial gases contain sulfur dioxide, carbon dioxide, nitrogen dioxide, hydrogen sulfide and ammonia, etc. Although these components are very small in content, the corrosion hazards to steel structure engineering cannot be ignored. Among them, sulfur dioxide has the greatest impact, and chlorine gas can damage the passivation film on the metal surface. These gases dissolve in water and become acidic, forming acid rain and corroding metal facilities.
In view of various fields, we should take corresponding protective measures, whether anti-corrosion or fire prevention. In a word, only by protecting the steel structure engineering can we make our tomorrow more brilliant.
The development of the steel structure engineering industry can be summarized as insisting on expanding and strengthening industries and enterprises. The industry is made up of enterprises, without which the industry cannot be bigger and stronger. For us, development is to strengthen the industry and enterprises. The transformation of the development mode of steel structure industry needs to adapt to circular economy and low-carbon economy.
Today is not what it used to be. Steel structure engineering has the advantages of fast construction speed, less construction pollution and light weight. These advantages make it the future development trend. Today, many buildings have begun to use steel structures. Steel structure engineering has realized factory and large-scale production. Compared with traditional construction engineering, it has short construction period, less on-site labor, high labor productivity and easy quality assurance.
Expandable container house uses its main space to make many parts (rooms) mobile. After the houses are transported to the site, they are slid out and fixed. This creates a larger building space and saves on shipping costs.
The container house is similar to the building, and the surrounding and the partition wall are leveled. It is best to use reinforced concrete, which is relatively strong. Then the column is used to connect the frame with the transverse beam, the upper partition, the outer wall panel and the door and window frame; , then put up a layer, then go up the roof truss and roof slab; finally install doors and windows, etc., pull the vertical support. There is also sanitary ware, hardware and the like.
In fact, this is a light steel structure, similar to a heavy steel structure factory.
Container concealed concealed project refers to the part of the construction process that will be covered by the next process after the completion of the previous process. The parts that cannot be inspected after completion are used for room decoration. The “concealed project” is the key if the concealed project "Not doing well, the surface is decorated beautifully, but also in vain.
"Concealed works" can be divided into water installation, electrical installation and moisture, waterproof and other projects. Each of these projects cannot be ignored. If any problem occurs, it may bring serious economic losses and even harm to personal safety. Waterproof engineering construction process and material identification to avoid unnecessary economic loss and damage.

1.reduce the energy consumption in the use and maintenance of buildings and alleviate the energy crisis;
2.reduce energy consumption while providing a comfortable and environmentally friendly working or living environment;
3.reduce the impact of urban development on the earth's ecology, such as carbon dioxide emissions and the urban heat island effect. According to relevant experts, in order to save energy and protect the environment, the U.S. Department of Energy has vigorously promoted the new technology of " zero - energy residential buildings".
Obviously, the Chinese government has already realized this, and has been committed to promoting energy conservation and environmental protection in all aspects and to promoting the sustainable development of the society.
In recent years, the cooperation and exchanges between China and the international community in the field of green buildings have become more and more extensive. These cooperation and exchanges have played a positive role in promoting the development of green buildings in China. Han Qide, chairman of the China Association for Science and Technology, said that as a responsible developing country, the Chinese government adheres to the scientific concept of development that is people - oriented, comprehensive, coordinated and sustainable, attaches great importance to tackling global climate change, while developing its economy, vigorously promotes energy conservation and emission reduction, slows down greenhouse gas emissions and has made unremitting efforts to this end.
China has adopted a series of strategic arrangements such as formulating a national plan to deal with climate change, building a resource-saving and environment-friendly society, building an ecological civilization, developing a circular economy and building a harmonious society. The goal of reducing energy consumption by 20% in GDP and achieving remarkable results in controlling greenhouse gas emissions has been set.
Light steel villa house, as a rising building material, naturally has its advantages and disadvantages. Light steel villas are still improving and progressing in this respect.
Advantages of Light Steel Villa:
It has very light weight, good stability and very good anti-seismic and anti-wind performance. Light steel materials can also be recycled and are green and environmentally friendly.
Disadvantages of Light Steel Villa:
The cost is high and requires regular maintenance, which is rather troublesome. Light steel houses have thin walls and do not sound insulation. Fire resistance is extremely poor. Not resistant to humidity. The quality is mixed and the whole industry is imperfect.
The construction speed of light steel villas is 7 - 8 times higher than that of ordinary buildings, which basically does not involve the problem of water consumption and is dry construction. Light gauge steel villas may weigh only one-fourth to one-sixth as much as traditional concrete buildings and are very light in weight. However, its stability is excellent, and steel structure houses have very good anti-seismic and wind-resistant performance. A layer of heat preservation material is pasted on the outer side of the wall body, so that the heat preservation effect can be achieved and the heat preservation and sound insulation effects can be achieved.
Light steel materials can also be recycled and are green and environmentally friendly. In addition, the service life of light steel villas can reach more than 70 years, while the traditional brick-concrete structure is 50 years.
The current situation of Chinese residents is characterized by high housing prices, inadaptability to live in, high work pressure and no happiness. With the development of the times, policy support makes more and more people more willing to return to their hometown to develop and take root in the countryside.
At present, the country is vigorously promoting green buildings, energy conservation and environmental protection, recycling, industrialization and industrialization of residential buildings, which are new industries that governments at all levels, property developers and investors are concerned about and promoting. At present, China's residential light steel structure accounts for less than 5%, compared with almost more than 50% in developed countries abroad, China is still in the initial stage, but light steel structure technology has now become mature, only now people know relatively little, light steel villas still have a lot of room for development.
Prospect 2: Light steel villas have many advantages to satisfy people's imagination.
Now a little pursuit of self-building owners, will abandon the rural building style of the same. Looking for a design company to design and build houses is too expensive, slow to build, and cannot meet the original design expectations. At present, light steel villas can meet all requirements and can be customized according to the whole, with various shapes and beautiful appearance. Light steel villa structure houses have fast construction speed and short construction period, which is more than half shorter than brick-concrete houses, and can be completed in 200 square meters and 90 days. Safe and reliable, the whole and foundation are designed with anti-pulling parts, which can prevent wind and disaster and has excellent sound insulation effect, making your living more comfortable.
Zhejiang Putian integrated house has rich experience in building light steel villas, and its products can withstand polishing for a long time. Welcome your inquiry. If you want to know more information or appreciate their classic cases, you can click here: prefab steel house.
With the accelerated pace of urbanization, the implementation of a series of central policies focusing on people's livelihood and the start of the implementation of new poverty alleviation programs, China's steel structure residential development has opened up the vitality of rapid recovery of operations. Prefab Steel House still has huge development space in the domestic market. China's steel structure enterprises will face the severe challenges of market changes, rising costs and personnel losses in the new round of development, and will also provide advantageous enterprises with a historical opportunity to merge, restructure, upgrade and become better and stronger.
Therefore, changing the mindset of only attaching importance to processing and manufacturing links, speeding up structural adjustment, equipment upgrading and marketing network construction, insisting on technological innovation as the support, continuously introducing marketable products in response to market changes, and striving to improve brand building capability are the inexhaustible driving forces for steel structure enterprises to become better and stronger today.
PTH has over 20 years of experience in this industry, and can provide full services to customers’ requirements covering design, manufacturing, logistic, installation, and after sales service.
With the fast growing of manufacturing industry, large steel structure is very much in demand. The unique advantages are high strength, capable of large span, environmental, seismic resistance etc. Its common applications are factory, warehouses, public buildings and other special application.
During the 1970s, prefab was huge. Designers and builders recognized that they could save time and build cheaper and more accurately if they produced homes in factories. So why are there so few prefab houses today?
From movie stars to environmental activists, the idea of prefab housing is gaining traction. Forward-thinking builders and architects have begun to embrace prefab building. Homes built offsite can be considerably cheaper and faster to put up. “The real saving is in time,” says Brian Abramson, co-founder and director of Method Homes. “It typically takes 50 percent less construction time to complete a prefab house.”
That’s because factory construction is automated and, since its indoors, won’t be subject to weather delays. Factories are able to more accurately predict delivery dates and homes just need to be assembled onsite, which reduces labor costs.
While the precision that working in a factory affords, prefab construction lends itself to the clean lines of modern architecture, but factory construction is able to handle any style of architecture.
The process of designing and building prefab homes doesn’t differ much from traditional homes. Once the property is acquired and mapped, the architect will design the home. Permits are obtained and the builder then works with the factory to complete the building elements and transport them to the site where they are assembled.
Prefab homes aren’t without their issues; permitting can take longer as some areas aren’t accustomed to these kinds of homes and transportation down narrow roads can make delivery difficult.
Zhejiang Putian Integrated Housing Co., Ltd. (also known as "PTH") has been dedicating itself to one-stop solution of low-rise prefabricated houses. The service ranges from architectural design, production, storage and transportation to installation instructions and after-sales service etc. The corporation has set up affiliated office in Canada , and has exported its products to over 100 countries and regions, with more than 2000 progects.
From the start to the full cap, the xiong'an new area Citizen Service Center project, with a total construction area of 99600 square meters, took only 1,000 hours. Prefabricated homes china has once again refreshed people's understanding of future buildings.
The Significance of Prefabricated Buildings in the Construction of " Green New Town" in Xiong 'an
" Green ecological livable new city" is the primary orientation of xiong'an new area, and " building a green intelligent new city" is its primary task. There is no doubt that 80% - 90% of xiong'an new area will be fabricated buildings. Because the overall planning progress is very fast - the prototype of the new city will appear in 3 years and the construction of the starting area will be completed in 5 years. The time requirement will promote the application of prefabricated buildings in the future construction of xiong'an new area. Taking a 30 - story building as an example, it takes only 180 days for 12 workers to use prefabricated building technology, which is at least 30% faster than traditional construction. However, the 1,000 - hour civil service center project, which basically completed the construction of the main structure, has proved the importance of prefabricated buildings in future buildings in xiong'an new area.
Why are prefabricated buildings so popular with xiong'an new area?
Prefabricated building is a building assembled with prefabricated building components on the site. Take Shenghao House as an example, the prefabricated building systems that can be realized at present include: cold-formed thin-walled light steel building system, modern light wood building system, heavy light steel hybrid building system, cold-formed thin-walled partition wall and enclosure wall product system.
The advantages of these building systems are fast construction speed, little restriction by climatic conditions, saving resources and energy, reducing construction pollution, saving labor and improving building quality. To put it figuratively, these building systems are the components of beams, columns, wallboards, balconies, stairs and other components needed by the building, which are all pre-produced by the factory and then transported to the construction site for assembly and combination. Simple, fast, reliable and guaranteed.
This is also the main reason why xiong'an new area, China's millennium development plan in the future, chose prefabricated buildings. In the near future, green industry, new energy industry and artificial intelligence industry will gradually replace traditional industries. Prefabricated buildings conform to the development trend of green building industry in the future and are the inevitable choice for the construction of xiong'an new area and more cities.
As the real future protagonist in the field of architecture, prefabricated buildings are developing vigorously in all aspects.
