2300 square meters unitized glass curtain wall exported to Oceania on June and August, 2022.   This project is nearing completion, much ahead of schedule. Our products have won unanimous praise from customers and are recognized by the local market.   Unitized glass curtain wall systems are composed of large glass units that are created and glazed within a factory and then sent to the construction site. Once arriving on site, the units can then be hoisted onto anchors connected to the building whatever concrete or steel buildings. High quality, due to tight tolerances of fabrication in a climate-controlled environment, is only one hallmark of this type of system. Because there is no on-site glazing, another major benefit of using a unitized system is the quicker speed of installation. The system can be installed in a third of the time of a stick-built system which means a lot of site time saving. This system is well suited for cases where there is a large volume of prefabricated unitized panels required, where there are higher field labor costs (thereby shifting the labor to a more cost-effective factory work force), where higher performance is needed (for wind loads, air/moisture protection, seismic/blast performance), for taller structures, and more regular conditions for panel optimization.   The unit glass curtain wall assembles panels and metal frames (beams, columns) into curtain wall units in the factory. The structural features of unit glass curtain walls in the form of curtain wall units are: first, the units (skeleton materials, glass, insulation Insulation materials) are assembled into a complete frame in a special factory, and then transported to the construction site. At the construction site, only one curtain wall unit needs to be installed and fixed to the main structure of the building in turn.   Because the columns are connected, their specifications should be consistent with the storey height and column spacing. When connected to a floor or beam, the height of the curtain wall should be equivalent to the story height or a multiple of the story height; when connected to the columns, the width of the curtain wall should be equivalent to the column spacing.   The advantages of unit glass curtain wall are: simple and fast installation on the construction site, shortening the construction period of the project.   Looking forward to your visit and inquiry.

Why is the seismic effect of steel structure buildings the best? • Strong toughness, good ductility, not easy to cause brittle failure; • Soft stiffness, light weight of the structure, small earthquake response; • High strength, not easy to yield or damage in earthquakes.   What are the advantages of steel structure buildings in terms of earthquake resistance? • Sufficient seismic study In recent years, after many studies on energy dissipation and shock absorption of steel structures, a representative damper was selected, and the shock absorption effect and economy were analyzed from the aspects of applicability, plane and elevation layout, structure height, fortification intensity and performance target. . • Reasonable structural arrangement In the design process, according to the functional requirements of the building, the energy-dissipating support and other components are arranged in the area that does not affect the building function, so that the plane is more concise and uniform, the earthquake resistance is more reasonable, and more seismic energy is dissipated. • Strict seismic measures In the area of ​​the beam-column connection node, the anti-seismic measures of welding the reinforcing plate to the beam end flange are adopted, so that the bearing capacity of the steel structure node is greater than the bearing capacity of the component, the structural integrity is better, and the earthquake resistance goal of ensuring that it does not fall over in a major earthquake. • Perfect construction control standards For the main seismic components of the structure (such as frame columns, frame beams, and buckling braces BRB, seismic ball bearings, etc.), on the basis of the specifications, there are more complete and detailed enterprise control standards to ensure the quality of processing and on-site construction. .

Doors and windows are an organic system composed of profiles, glass, hardware accessories and sealing strips. Energy-saving and environmental protection system doors and windows can fundamentally solve the problem of high energy consumption in buildings. Therefore, the implementation of energy-saving and environmental protection system doors and windows is one of the preferred solutions for building energy consumption.  Profile Different thermal conductivity determines the different energy consumption of doors and windows.

"Door system": It is a system developed for engineering design, manufacture, and installation of building doors and windows that meet the set performance and quality requirements. . "System doors and windows": It is a perfect organic combination of performance systems. Using the system integration way of thinking, based on the door and window systems developed for different regional climate environments and functional requirements, various performances, such as water tightness and air tightness, need to be considered. , wind pressure resistance, heat insulation, sound insulation, heat preservation, anti-theft, operating feel, etc., are designed, manufactured and installed in accordance with the overall solution requirements and strict procedures, and finally form high-performance system doors and windows with high reliability and high cost performance. Building doors and windows. The real energy-saving system doors and windows are not single use of heat-insulating broken bridge aluminum profiles or Low-E insulating glass energy-saving materials. It is a perfect combination of a system, and the comprehensive results of the performance of each link are indispensable. At present, the most representative brands in the domestic market include: YKK AP, Jiayu, Aluk, Beiluo, Shubiao, Feiyu and other brands. Convection: The loss of heat is the circulation of hot and cold air through the gap between doors and windows, and the heat is exchanged through gas convection, resulting in heat loss; Conduction: Heat conduction is the heat transfer by the molecular movement of the material itself used for doors and windows, and it is transferred from one side of the material to the other side, resulting in heat loss; Radiation: Radiation is mainly transmitted directly in the form of rays, resulting in loss of energy consumption. What is the difference between system doors and windows and ordinary doors and windows? 1. In terms of stability and performance The system doors and windows have their own independent technical department, which will carry out strict tests and inspections on each component of the system doors and windows, so the components are well matched and are not prone to failure, which is what we often call good stability. Ordinary doors and windows are assembled by ordering different parts according to their own needs, but there will be some problems in the process of use, and the stability is relatively poor. After 2 to 3 years of research and development of system doors and windows, the materials, the performance and quality of the entire doors and windows are comprehensively tested, and mature products are launched after reaching the expected goals. Ordinary doors and windows are temporarily integrated door and window products for a single project, often without comprehensive testing. 2. Flexibility The various components of the system doors and windows have been fixed according to different performances, and the room for selection is relatively small compared with ordinary doors and windows, so the flexibility is small. Ordinary doors and windows can flexibly configure their own components according to their own needs. System doors and windows are serialized and standardized products, with strong exclusivity and incompatibility in slot structure and material supply, and can only be selected according to the needs of the project. Generally, individual projects will not be developed. Common door and window materials can be selected by domestic and foreign manufacturers, and can also be temporarily opened, with strong flexibility. 3. Software aspects While providing products, system doors and windows also provide design software, design manuals, procurement manuals, processing manuals, professional special equipment and technical service support, which is a complete industrial chain. The quality of ordinary doors and windows depends on the level of designers and the ability of door and window enterprises to process and install.

The photovoltaic (PV) ventilated façade curtain wall and roof system are a product with undeniable aesthetic value and unbeatable in terms of heat insulation that generates free electricity from the sun. The generated electricity can be translated directly to the mains supply system, thus being marketed to the large suppliers, or be used for personal consumption (isolated system).   Earlier generations of PV for buildings utilized solar panels mounted directly onto the building roof with minimal aesthetic considerations. This concept was replaced by building-integrated PV systems, where the PV modules actually came to replace parts of the building envelope, providing functional considerations and lowering costs. More recently, thin-film PV technologies have begun to enable the seamless integration of PV onto buildings, and will likely succeed in markets where their superior flexibility, minimal weight, and improved ability to perform in variable lighting conditions gives them a significant competitive advantage over conventional solar technologies.   However the success of creating new BIPV markets will depend on many variables, including: 1. Concerted efforts by players in the BIPV supply chain to work together towards the design and integration of solar into the building envelope; 2. Costs in $/Wp, as well as the building industry’s preferred metric of $/m2, of product and power availability; 3. Development of specific standards and building codes; 4. Availability of federal and local incentives to ensure cost effectiveness; 5. Added value for consumers and architects; and 6. Ease of production and the scale at which a production plant becomes economically feasible.   Incentive schemes in favour of BIPV For some time, thin-film solar technologies have not been at a price point to make them truly competitive with conventional solar-based panel systems that are just "slapped" onto buildings, but this is changing due to the current round of incentive schemes, and GTM research expects that thin-film solar technologies will soon play a significant energy role in both the applications and the markets in which conventional solar materials are currently employed, as well as in markets where conventional solar materials are unsuitable for various reasons, such as façades, roofs and window applications.   A definition of BIPV and BAPV There is some confusion regarding the definition of BIPV within both the PV industry and the building industry. GTM Research defines BIPV as building-integrated PV, which requires that the building team along the entire supply chain - including architects, building designers, engineers, building owners and utility companies - work together to design and build the photovoltaics into the building’s very "skin" as an element, from the inception of the project onwards. BAPV, on the other hand, is defined as building-applied PV. In this process, the photovoltaics are a retrofit, added to the building after construction is completed.   The thermal surrounding methods can result in a 25-40% reduction of the energy consumed by a building. Depending upon the orientation of the façade, building location, and the photovoltaic technology implemented, the electricity produced by our system in just one square metre can vary between 20-40 kW/h per annum; sufficient energy to supply up to 10,000 hours of light from 20W energy saving light bulbs. In addition to the obvious environmental benefits, in countries where the sale of electricity is regulated and incentive based, through an obligatory subsidy from the electrical companies, one metre squared of ventilated roof can generate a net benefit in its lifetime (25 years) of more than 1000 Euros. From a financial point of view, depending upon the type of building and its location, our ventilated façades and roofs can achieve an Internal Return Rate (IRR) greater than 25% and an outstanding payback time.

Although the cost of fuel has soared, the originally high international sea freight has fallen significantly recently. The actual shipping price of container ships has dropped by an average of about 20% from the Spring Festival to the present.   One of the reasons behind this is that the upgrade of epidemic prevention and control in some parts of the country has caused supply chain blockages, which has changed and adjusted the market supply and demand relationship that was originally "hard to find in one box". At the same time, changes in the international situation have also affected the global consumer market.

Low-E glass, also known as low-emissivity glass, is a film-based product composed of multiple layers of metal or other compounds plated on the glass surface. The coating layer has the characteristics of high transmission of visible light and high reflection of mid- and far-infrared rays, which makes it have excellent heat insulation effect and good light transmittance compared with ordinary glass and traditional architectural coated glass. Glass is an important building material. With the continuous improvement of the decorative requirements of buildings, the use of glass in the construction industry is also increasing. Today, however, when people choose glass windows and doors for buildings, in addition to their aesthetic and appearance characteristics, they pay more attention to issues such as heat control, cooling costs and the comfort balance of interior sunlight projection. This makes the upstart Low-E glass in the coated glass family stand out and become the focus of attention.   Excellent thermal properties The heat loss of exterior door and window glass is the main part of building energy consumption, accounting for more than 50% of building energy consumption. Relevant research data shows that the heat transfer on the inner surface of the glass is mainly radiation, accounting for 58%, which means that the most effective way to reduce the loss of heat energy is to change the performance of the glass. The emissivity of ordinary float glass is as high as 0.84. When a layer of silver-based low-emissivity film is coated, the emissivity can be reduced to below 0.15. Therefore, the use of Low-E glass to manufacture building doors and windows can greatly reduce the transfer of indoor heat energy caused by radiation to the outdoors, and achieve ideal energy-saving effects. Another significant benefit of reduced indoor heat loss is environmental protection. In the cold season, the emission of harmful gases such as CO2 and SO2 caused by building heating is an important source of pollution. If Low-E glass is used, the fuel consumption for heating can be greatly reduced due to the reduction of heat loss, thereby reducing the emission of harmful gases. The heat passing through the glass is bidirectional, that is, the heat can be transferred from the indoor to the outdoor, and vice versa, and it is carried out at the same time, only the problem of poor heat transfer. In winter, the indoor temperature is higher than the outdoor, so insulation is required. In summer, the indoor temperature is lower than the outdoor temperature, and the glass is required to be insulated, that is, the outdoor heat is transferred to the indoor as little as possible. Low-E glass can meet the requirements of winter and summer, both heat preservation and heat insulation, and has the effect of environmental protection and low carbon.   Good optical properties The visible light transmittance of Low-E glass ranges from 0% to 95% in theory (6mm white glass is difficult to achieve), and the visible light transmittance represents the indoor lighting. The outdoor reflectivity is about 10%-30%. The outdoor reflectivity is the visible light reflectivity, which represents the reflective intensity or dazzling degree. At present, China requires the visible light reflectivity of the curtain wall to be no more than 30%. The above characteristics of Low-E glass have made it increasingly widely used in developed countries. my country is a relatively energy-deficient country. The per capita energy consumption is very low, and building energy consumption accounts for about 27.5% of the country's total energy consumption. Therefore, vigorously developing the production technology of Low-E glass and promoting its application field will surely bring significant social and economic benefits. In the production of Low-E glass, due to the particularity of the material, it has higher requirements for cleaning brushes when it passes through the cleaning machine. The brush wire must be high-grade nylon brush wire such as PA1010, PA612, etc. The diameter of the wire is preferably 0.1-0.15mm. Because the brush wire has good softness, strong elasticity, acid and alkali resistance, and temperature resistance, it can easily remove the dust on the glass surface without causing scratches on the surface.   Low-E coated insulating glass is a better energy-saving lighting material. It has high solar transmission, very low "u" value, and, due to the effect of the coating, the heat reflected by the Low-E glass is returned to the room, making the temperature near the window glass higher, and people are not safe near the window glass. will feel too uncomfortable. The building with Low-E window glass has a relatively high indoor temperature, so it can maintain a relatively high indoor temperature in winter without frost, so that people indoors will feel more comfortable. Low-E glass can block a small amount of UV transmission, which is slightly helpful in preventing fading of indoor items.
