Factory Introduction and Advantages

In 2008, Tianjin Xinruifeng Technology Co., Ltd. was established in the beautiful coastal city of Tianjin. After more than a decade’s development, we are now manufacturing and trading combo with excellent capabilities in design, development, production, and export. Our main products include drywall screws, chipboard screws, self-drilling screws, and self-tapping screws, which are produced in 3 different production bases with a total area of 16,000 square meters.

We have 280 sets of automatic production equipment, including wire drawing machines, cold-heading machines, thread rolling machines, tailing machines, and heat-treatment lines. There is more than 100 staff in our company. Among them, there is an experienced and professional R&D team, that follows an established management system and quality control procedure, allowing us to customize the products according to your specific designs/requirements to the highest quality. 

Application

Self-Drilling Screws for Metal

Self-drilling screws can be used to fasten sheets of metal to another material, or even to join metal to metal. Not only does this set them apart in comparison to other common screw types, but it also makes them highly useful across a broad spectrum of industries and applications. To name just a few examples, ideal uses could include working with metal roofing, HVAC and ductwork, and steel frames.

Self-Drilling Screws for Wood

While purpose-manufactured wood screws are typically the first choice for tasks involving wood, self-drilling screws may also prove useful in certain woodworking scenarios. For instance, self-drilling screws for wood may be used in the construction, repair, or maintenance of sheds and outbuildings, as well as general construction tasks.

Self-Drilling Screws for Plastic

Self-drilling screws can also be used with plastic in certain applications and environments. One instance of using self-drilling screws with plastic could be to fasten sheets or components together when working with ductwork and plastic piping.
