This issue shares the construction case of Beijing Millet automobile factory. The products used in this project include: Yingfeng galvanized nails, coated nails, explosion-relief wall system, explosion-relief roof system, etc., among which, the number of screws used exceeds one million sets.

As seen above, this issue is sharing the construction case of Beijing Xiaomi Automobile Factory, and the products used in the project include: Ying Feng galvanized nails, coated nails, explosion-vented wall systems, explosion-vented roofing systems, etc., among which the number of screws used exceeds one million sets.

The above example products are more common and best-selling products of Yingfeng, as shown in the figure. Through observation, we can find that these products have obvious differences in head shape, rod diameter, length, appearance (such as color, etc.) :
① Large production factories have high requirements for the material and hardness of construction screws. It can also be seen from the product list of the project that the material of the products we provide is mainly carbon steel;
Yingfeng carbon steel screws generally use 1022A, 10B21 high carbon steel, and the use of imported equipment for carburizing heat treatment, screw surface hardness ≥HRC55, HRC40≥ core hardness ≥HRC32, conventional 12-14TY-B screw tensile force > 11000N, shear force > 8000N, The drawing force of 3mmQ355 steel plate is ≥6000N, which has better mechanical properties than the general products in the market, and is also more in line with the requirements of the Millet automobile factory project for construction screws;
(2) In the four products shown in the picture, there are obvious differences in head shape, rod length, thread and color, which are customized according to the application of the building and the specific requirements of customers, among which the more special is colored paint nails, which can be colored according to the requirements;
Of course, it is important that these products will be used in different construction areas depending on the surface treatment method and the level of salt spray.

As we have learned before, Yingfeng can provide a full set of pressure relief devices (including test reports, FM certification reports), our explosion-relief products can be used with any plate, panel, on-site assembly or workshop assembly wall with or without insulation layer, which can effectively reduce the probability of secondary injury, achieve the purpose of protecting personnel life and property safety, and make it easier to repair after explosion. The construction of millet automobile factory adopts Yingfeng full set of explosive-releasing device, which can effectively avoid the problem of explosive-releasing that may occur in production, and is also a high recognition of Yingfeng products.

In the conventional self-tapping nails used in the construction project of millet automobile factory, the number of galvanized nails is large. Do you remember what characteristics of Yingfeng galvanized screws? Yingfeng galvanized screw adopts trivalent environmental protection zinc, film thickness requirements ≥6um, salt spray requirements ≥200H no red rust, and requires "zero hydrogen embrittlement", no brittle break "phenomenon, can provide material reports and third-party testing reports. (For more information, see "How to quickly determine the quality of electroplating self-tapping nails")

Recently, millet SU7 has been in hot sales, as one of the building materials suppliers of millet automobile factory, Yingfeng here congratulates the light of domestic cars - the rise of millet, and wishes we can all break through the thorns and prosper in their respective fields. That's all for this episode! Welcome to consult for more product information.
