Why can Winged self Drilling Screw stand out in roof and wall construction? ​

Unique design helps fit and tighten​
Wings: the secret weapon for drilling and expanding the diameter
The wings of Winged self Drilling Screw are the exquisiteness of its design. When construction workers apply it to roof and wall construction to fix building panels such as color steel plates, aluminum plates, and gypsum boards, the wings begin to play a magical role. In the process of drilling into the plate, the wings are like a skilled cutting master, relying on special shapes and precise angles to efficiently cut the plate material. The result is not only that the hole is drilled, but more importantly, the hole diameter is expanded simultaneously. This unique expansion effect enables a tighter fit between the plate and the base layer. Taking the construction of color steel plate roof as an example, the hole diameter of ordinary screws after drilling is limited to the adaptability of the screw, and there is a slight gap between the plate and the base layer, which is prone to loosening under long-term wind and sun. The wing-shaped self-drilling screw expands the aperture through the wing, so that the color steel plate and the roof base are firmly attached, effectively reducing the gap, greatly enhancing the firmness of the connection, and laying a solid foundation for the stability of the roof. ​
Head: The wisdom of pressure dispersion
The head design also contains ingenuity. When fixing building panels, the head of the wing-shaped self-drilling screw can provide a larger contact area than ordinary screws. When external pressure is applied to the board, for example, in strong winds, the wall or roof board will be subjected to huge wind pressure. At this time, the head of the wing-shaped self-drilling screw is like a calm pressure "resolver". The larger contact area allows the pressure to be evenly dispersed, avoiding the deformation or damage of the board due to excessive local force caused by concentrated pressure. In the construction of gypsum board walls, the texture of gypsum board is relatively brittle and has limited pressure tolerance. If ordinary screws are used, once the pressure is concentrated, the gypsum board is very likely to crack. The wing-shaped self-drilling screw can evenly disperse the pressure to the surrounding area with its head design, effectively protecting the integrity of the gypsum board and ensuring the beauty and safety of the wall.​
A versatile tool for various sheet materials
Metal sheet connection: a strong and stable guarantee
In roof and wall construction, metal sheets such as color steel sheets and aluminum sheets are widely used. Wing-shaped self-drilling screws are excellent for connecting such metal sheets. Their self-drilling function enables them to easily penetrate the metal surface without the tedious process of pre-drilling, which greatly improves construction efficiency. In a color steel sheet roof installation project in a large factory, the construction team used wing-shaped self-drilling screws, which greatly increased the installation speed compared to the traditional method of drilling holes first and then installing screws. Moreover, due to the wing and thread design of the wing-shaped self-drilling screws, after penetrating the metal sheet, it can form a tight bite with the sheet, providing a strong fastening force. This strong connection method allows the roof to remain stable in the face of severe weather, such as strong winds and rainstorms, without the risk of loosening or falling off of the sheet, providing reliable protection for the safety of equipment and personnel inside the factory.

Fixing of non-metallic sheets: gentle and firm care
For non-metallic sheets such as gypsum boards, wing-shaped self-drilling screws also show extraordinary adaptability. The texture of gypsum board is relatively soft, so it needs to be handled gently during the fixing process to avoid damaging the board. When the wing-shaped self-drilling screw is drilled into the gypsum board, its sharp tip and special thread design can minimize the damage to the gypsum board structure while ensuring smooth drilling. At the same time, the wing expands the aperture and the head disperses the pressure to achieve a firm fixation of the gypsum board. In the construction of gypsum board ceilings in residential decoration, wing-shaped self-drilling screws ensure the stability of the ceiling. Even during long-term use, the gypsum board will not fall due to slight vibration or gravity, creating a safe and comfortable living environment for residents. ​
Key role in the exterior wall insulation system ​
Stable connection between insulation board and decorative panel ​
In the exterior wall insulation system of residential buildings, wing-shaped self-drilling screws have a vital mission. As the core part of the insulation system, the insulation board needs to be closely connected to the wall base, and the decorative panel should be covered on the outside of the insulation board to play a protective and decorative role. The wing-shaped self-drilling screw plays a bridging role here. It passes through the decorative panel and the insulation board in turn, and finally fastens to the wall base. In this process, the advantages of the wing and head design of the wing-shaped self-drilling screw are fully demonstrated. When penetrating multiple layers of materials, the wing effectively expands the aperture, so that each layer of material fits tightly; the head evenly disperses the external pressure on the decorative panel to prevent the decorative panel from breaking due to uneven pressure. In the construction of residential exterior wall insulation in cold areas, the outdoor temperature is extremely low in winter, and the insulation system faces severe tests. With its stable connection performance, the wing-shaped self-drilling screw ensures that the insulation board and the decorative panel are still closely connected in a low temperature environment, and will not fall off, continuously providing good insulation effect for the room, reducing energy consumption, and improving living comfort. ​
Improving the overall performance of the insulation system​
The use of wing-shaped self-drilling screws not only realizes the simple fixation of the insulation board and the decorative panel, but more importantly, improves the performance of the entire exterior wall insulation system. Because it can ensure that the layers of materials fit tightly together, it reduces the gaps for air infiltration. In the hot summer, it is difficult for the hot air from the outside to enter the room through the gaps, which effectively blocks the heat conduction; in the winter, the heat in the room is not easy to dissipate. This good sealing performance greatly improves the thermal insulation effect of the insulation system, significantly reducing the energy consumption of the building. At the same time, the stable connection also enhances the durability of the insulation system. Under the influence of natural factors such as long-term wind, sun, temperature changes, etc., the insulation system can still remain stable, prolonging its service life, reducing the later maintenance cost, and providing strong support for the sustainable development of the building. ​
Double improvement of construction efficiency and quality ​
Easy installation, saving construction time ​
In roof and wall construction, time is cost. The self-drilling function of the wing-shaped self-drilling screw greatly simplifies the installation process. The traditional screw installation method requires first using a drilling tool to drill holes in the board and the base layer, and then screwing in the screws. The process is cumbersome and time-consuming. The wing-shaped self-drilling screw only needs to use a screwdriver or power tool to complete the drilling, tapping and tightening operations at one time. In a medium-sized wall decoration project, the use of wing-shaped self-drilling screws for plate fixing shortened the construction time by nearly one-third compared with traditional methods. This not only means that the construction team can complete the project in a shorter time and improve work efficiency, but also saves time and cost for the owner, allowing them to move in or use the building space faster. ​
Firm connection to ensure construction quality​
Construction quality is the lifeline of the building, and wing-shaped self-drilling screws perform well in this regard. The strong fastening force and stability brought by its unique design ensure that the connection between the plate and the base is firm and reliable. In roof construction, a firm connection can resist the erosion of natural factors such as wind, rain, and snow, and prevent problems such as roof leakage and plate shedding. In wall construction, a firm fixation ensures the flatness and verticality of the wall, and avoids quality risks such as wall deformation and cracking caused by loose plates. In the exterior wall construction of high-rise buildings, the firmness of the connection is extremely high. With its excellent performance, wing-shaped self-drilling screws meet this stringent requirement and provide a solid guarantee for the safety and beauty of high-rise buildings.
