China FAMOUS Steel Engineering Company Company News

In Suzhou, one of China's most livable cities, a new 460-meter tall landmark building will rise quietly in the central business district on the western shore of Jinji Lake, forming a unified urban architectural complex facing Jinji Lake, along with the Gate of the East, Suzhou South Central Center and Suzhou Central Plaza.   The facade of Suzhou Zhonghai Super Tower utilizes sustainable design elements, including photovoltaic panels integrated throughout the podium and high-performance glass panels, effectively reducing the building's reliance on heating and air conditioning.   The podium, in the form of an open ride, is connected to the nearby Suzhou Center by a pedestrian promenade on the east side, with a series of glass light roofs that bring natural light and views of the tower into the commercial spaces on the first floor.   At the same time, the undulating facade, composed of metal grilles and glass curtain walls, creates a three-dimensional light and shadow effect of water ripples for the tower, using the light and shadow at different times of the day, angles and weather. In addition, the façade shape is inspired by the ancient scrolls that unfold slowly, expressing respect to this thousand-year-old cultural and historical city.   Suzhou China Shipping Super Tower is expected to be completed in 2027. The project will use low-carbon building materials, reduce water and energy use throughout the building system, meet strict indoor air quality requirements, and meet top industry green building certifications such as LEED Platinum, Green Building Three Star, CABEE Ultra Low Energy Building, WELL certification, and Healthy Building Label.   In addition, according to the design plan, the project façade will adopt "golden" glass curtain wall throughout, which can also be said to be another ceiling of value by the Jinji Lake.

1500 Tons Steel Truss Structure Members Exported to Oceania on August, 2022.   A steel truss refers to a truss made of steel. In the roof structures, crane beams, bridges and hydraulic gates of industrial and civil buildings, steel trusses are often used as the main load-bearing components. All kinds of towers, such as mast towers, TV towers and transmission line towers, are commonly used space steel trusses composed of three-sided, four-sided or multi-sided planar trusses.   The most commonly used is the plane truss, which is essentially a lattice beam under the action of lateral loads. Compared with solid-web steel beams, steel trusses are characterized by chords instead of flanges and webs instead of webs. Rods and chords are connected to each other; sometimes the members can be welded (or otherwise connected) directly to each other without the use of gusset plates. In this way, the bending moment of the plane truss as a whole is expressed as the axial compression and tension of the upper and lower chords, and the shear force is expressed as the axial compression or tension of each web member.   Application: Trusses are widely used in steel structures, such as roofs (roof trusses, etc.) and crane beams (ie crane trusses) of industrial and civil buildings, bridges, cranes (its towers, beams or booms, etc.), hydraulic gates, In offshore oil production platforms, steel trusses are often used as the main components of load-bearing structures. Various types of steel grids, which are widely used in the roof structure of large-span public buildings, belong to space steel trusses. Various types of towers, such as TV, power transmission, drilling, crane towers and mast towers, often use space steel trusses composed of three-sided, four-sided or multi-sided planar trusses.   Looking forward to your visit and inquiry.

On the afternoon of September 16, 2022, a fire broke out in the China Telecom Building in the urban area of Changsha, Hunan Province. Thick smoke billowed from the scene, and dozens of floors burned violently.   The telecommunications building was built in 2000 and is located in the East Second Ring Road of Changsha City. It was the first building in Changsha to exceed 200 meters with a height of 218 meters.   Now, after a few minutes of fire, the building has turned into such a "black" color... Whether it is the owner, or the design, construction unit and material suppliers, or practitioners in the door, window and curtain wall industry, they all feel a while heartbroken.   In high-rise building fires, the fire tends to spread rapidly upwards in a short period of time, which is due to the "chimney effect" formed by high-rise buildings! The phenomenon of enhanced convection of air.   In recent years, there have been quite a number of high-rise and super-high-rise curtain wall buildings whose exterior wall materials, design and construction do not meet the requirements of current regulations. When a fire occurs, there is a risk of spreading throughout the building, and more attention needs to be paid!   At the same time, behind the accident again and again, is our thinking on the design height of the future building curtain wall and the selection of external wall insulation materials!

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. Using high-quality broken bridge aluminum alloy profiles, multi-cavity structure and multi-layer sealing design, the product has excellent air-tight performance and water-tight performance, greatly reducing indoor and outdoor heat conduction caused by air convection, and reducing the loss of air conditioning and heating , save energy and realize low-carbon life. Grass It is mainly due to thermal radiation loss of energy. To ensure the energy saving of the overall building, it is necessary to choose glass reasonably. The high-quality glass has a special process to form a hollow layer, which greatly reduces the thermal conductivity, effectively improves the thermal insulation performance and energy-saving effect of the glass, and can also prevent the glass from fogging and frosting. Sealant strip It has a non-negligible impact on the wind pressure resistance, water tightness, air tightness, thermal insulation, thermal insulation and other properties of doors and windows. It is durable and anti-aging, multi-layer protection, strong toughness, stable structure, and more stable and lasting sealing performance. It plays a vital role in the quality of energy-saving doors and windows. Hardware Accessories It is the component responsible for tightly connecting the frame and fan of doors and windows, and it is also an important component that affects the performance of doors and windows. The opening and closing requirements of doors and windows are inseparable from the needs of hardware accessories. It not only has the effect of indoor environment decoration, but also is directly related to the safety, comfort and energy saving of the building. In order to ensure the six properties of wind pressure resistance, water tightness, air tightness, thermal insulation, sound insulation and anti-theft of doors and windows, high-quality hardware accessories are selected to ensure the performance indicators of doors and windows.

520 Tons Steel Mesh Exported to Oceania on Mar. 2022.

"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.
