Metal roofing systems demand fastening solutions that can withstand extreme environmental forces. From high-velocity hurricane zones to corrosive industrial atmospheres, the selection of the correct self-tapping screw is critical to preventing structural failure and water ingress. As a leading manufacturer and supplier based in China, Beiersdorf Industrial Technology integrates advanced metallurgy and precise thread-forming engineering to deliver fasteners that exceed global standards.
Information Gain: Unlike standard fasteners, specialized metal roofing self-tapping screws feature a dual-thread design, integrated EPDM washers, and advanced anti-corrosive coatings (such as Ruspert or zinc flake) to guarantee a leak-free service life exceeding 25 years.
The performance of self-tapping screws is heavily dependent on their material composition. Carbon steel screws offer excellent shear strength but require robust surface coatings to prevent rust. Stainless steel options (such as Grade 304 or 316) provide superior corrosion resistance but are softer, often requiring a carbon steel drill point (bi-metal screws) to successfully penetrate thick metal purlins without pre-drilling.
Beiersdorf specializes in high-performance alloys, including titanium, nickel, and cobalt alloys, allowing us to supply fasteners that maintain structural integrity in temperatures ranging from -270℃ up to 1200℃. This level of material diversity ensures that whether your project is an arctic research station or a high-temperature smelting facility, our fasteners will not fail.
Water penetration is the primary cause of metal roof degradation. Our self-tapping screws are assembled with vulcanized EPDM (Ethylene Propylene Diene Monomer) washers. EPDM resists ozone degradation, UV radiation, and extreme temperature fluctuations. When driven correctly, the washer compresses to form a hermetic seal around the penetration point, preventing moisture from reaching the underlying steel structure.
We combine state-of-the-art manufacturing with rigorous testing protocols to deliver zero-defect fasteners.
Our "Hash Detection" system represents the most stringent sampling inspection process in the industry, aiming for absolute zero-defect delivery from our Shanghai facility.
We have formulated the most stringent sampling inspection system, so as to strive to achieve zero defects for the products out of our factory.
At present, our entire group has more than 100 utility model patented products and eight invention patented products.
We currently operate nearly 100,000 product models, with 500 tons of special raw materials in stock and 10,000 tons of finished stainless steel standard parts in stock.
China's fastener manufacturing sector is supported by an unparalleled ecosystem of raw material suppliers, heat treatment facilities, surface coating specialists, and logistics hubs. Based in Shanghai, Beiersdorf leverages this geographical advantage to source high-grade steel, titanium, and nickel alloys efficiently. This integrated supply chain allows us to maintain competitive pricing while enforcing strict quality control measures that are often fragmented in other regions.
Our 2,535 m² production base is equipped with advanced multi-station cold heading machines and high-speed thread rollers, enabling high-volume production with micron-level precision. This capacity ensures we can meet the massive volume demands of global infrastructure projects without compromising on delivery timelines.
Every construction market has unique requirements based on local building codes and environmental conditions. We provide comprehensive OEM and ODM services, allowing clients to customize screw lengths, thread pitches, drill point geometries (such as Tek 3 or Tek 5), and head styles (hex washer head, pancake head, wafer head). Our engineering team works directly with your technical staff to design fasteners tailored to specific substrate thicknesses and pull-out requirements.
Beiersdorf Industrial Technology (Shanghai) Co., Ltd. was established in 2015 and is located in Shanghai, China. It is an enterprise mainly engaged in the business of special fasteners and ultra-high precision components.

Different geographic regions present distinct environmental challenges. For instance, coastal regions require fasteners with high resistance to salt spray (tested up to 3000 hours in salt spray chambers), while seismic zones demand high shear strength to accommodate structural movement. Beiersdorf ensures all metal roofing self-tapping screws comply with international standards, including ASTM, DIN, ISO, and AS3566 (Australian Standard for self-drilling screws for the building and construction industries).
Our engineering team provides localized support, helping procurement managers select the correct coating thickness and base metal to prevent galvanic corrosion between the screw and the roofing sheet.
For marine and offshore applications, standard fasteners are insufficient. Beiersdorf is proud to supply fasteners certified by major classification societies (such as CCS). These fasteners are designed to withstand the harsh, corrosive marine environment, making them ideal for coastal warehouses, offshore platforms, and shipbuilding projects.
Our special fasteners are widely used in the field of shipbuilding and oceanography engineering, specifically in the manufacture of special ships, marine propulsion, marine accessories, yacht manufacturing, offshore oil drilling platforms, submarine pipelines, offshore wind power, underwater lifeboats, port machinery, dock construction, etc. These special fasteners mainly include A4-80, A5-80, D8-80, D6-70, 2205, L7, 40CrNiMoA, 718, EN14399 steel structure connection pair, classification society certificate fasteners, etc.

The demand for bi-metal self-tapping screws is rising rapidly. By fusing a hardened carbon steel drill point with a corrosion-resistant stainless steel body, these screws allow rapid drilling into heavy steel purlins while ensuring the exposed head remains completely rust-free for decades.
Environmental regulations are driving the phase-out of hexavalent chromium coatings. The industry is shifting toward organic zinc-flake and ceramic coatings that offer superior galvanic protection without environmental hazards.
With the global push for renewable energy, metal roofs are increasingly used as platforms for solar arrays. This requires specialized self-tapping fasteners that can support the additional load and resist the wind uplift forces acting on solar mounting brackets.
