In all kinds of fastening scenes of industrial manufacturing, engineering construction and home improvement production, small screws are the core basic accessories to ensure stable structure and good equipment. With the unique advantages of self-drilling and self-tapping, one nail in place, and no pre-drilling, the drilling screw breaks the pain point of tedious and inefficient traditional screw installation. Without complex drilling, tapping and welding processes, the drilling screw can directly penetrate the thin metal plate to complete the fastening and fixation. With the characteristics of high efficiency, firmness and strong adaptability, it deeply penetrates many industries and becomes a must-have accessory for lightweight metal connection, prefabricated construction and batch assembly, which has great industrial value and practicality.
I. Construction steel structure industry: the core tool of prefabricated construction
The construction industry is the most widely used and the largest amount of drilling screws, and it is also the scene where its advantages are the most extreme, especially suitable for steel structure engineering and prefabricated construction. Traditional steel structure plate fixation depends on welding and drilling bolt fixation, the process is cumbersome, the construction period is long, and the solder joint corrosion and plate deformation are prone to occur, while the drilling screw perfectly solves these industry pain points.
In the construction of steel structure workshop, the drilling screw is mainly used for color steel tile, galvanized steel plate, wall retaining board and light steel purlin, I beam, channel steel fixation, can directly penetrate the thin steel plate within 1.5mm, integrated drilling, tapping, locking three processes, compared with the traditional process can save more than 60% of the construction period. After the actual measurement, the roof system fixed by high-quality drill tail screws can withstand 12 strong winds, the connection tightness is greatly improved, and the shear resistance can reach 4.5kN, which fully meets the structural safety standards of industrial plants.
In the construction of light steel villa and prefabricated house, it is suitable for the splicing and fixation of light steel keel, OSB plate and exterior wall decorative plate, with anti-corrosion coating process, and the service life can be extended to more than 15 years in the coastal salt fog, wet and rainy environment. At the same time, the partition wall construction, ceiling installation and metal kicking line fixation in the assembly decoration also rely on the drilling screw to achieve rapid assembly, taking into account the construction efficiency and installation accuracy, which conforms to the development trend of lightweight and efficient modern architecture.
Ii. New energy industry: durable and fastening guarantee for outdoor infrastructure
With the rapid development of photovoltaic, energy storage, wind power and other new energy industries, outdoor infrastructure scenarios require high weather resistance, stability and durability of fasteners. Drill tail screws have become the core accessories of new energy projects with excellent anti-corrosion, anti-vibration and high tensile performance.
In the construction of photovoltaic power stations, photovoltaic supports are mostly made of thin galvanized steel and aluminum alloy, which are exposed to the sun and weathered by wind and rain for a long time. The special coated drill tail screw can directly fix the photovoltaic bracket and C-shaped steel purlin, the tensile strength can reach 15kN, the fastening-stability is very strong, not easy to loose and fall off, and can meet the basic requirements of the photovoltaic system for 50 years of long-term use. At the same time, its dacromet, zinc-nickel alloy and other anti-corrosion coatings, can resist outdoor ultraviolet light, rain, salt spray corrosion, greatly reducing the cost of photovoltaic power station later operation and maintenance.
In addition, the assembly of wind power equipment shell, energy storage equipment cabinet, new energy charging pile metal shell, also widely used drilling screws. In view of the working conditions of outdoor vibration and large temperature difference, the drill tail screw with anti-loosening structure can keep the preload, effectively avoid the hidden danger of loosening after long-term use, and ensure the stable operation of new energy equipment.
