Sandwich panels are used in various types of buildings, including: • Wall: Frequently used as exterior cladding or interior partition walls in industrial and commercial structures. In some refurbishment or fixing project, for example, sandwich panels were selected as they provided a quick solution for upgrading the facade while enhancing performance. • Roof: Light weight characteristic makes them perfect for roofing applications in large commercial facilities, delivering superior insulation properties while minimizing the structural burden. sandwich panels for a sports complex roof design where soundproofing qualities were equally important.
Self-drilling screws are a multipurpose and efficient fastening solution for metal-to-metal applications. Unlike traditional screws, they avoid the need for pre-drilling pilot holes, saving time and effort. Whether you're working with sheet metal, steel framing, or other metal materials, self-drilli
There are two most common types of corrosion for fasteners in walls and roofs of light buildings: atmospheric corrosion and chemical corrosion.Tsingri has always been a supplier of self tapping screw and self drilling screws for construction that implements natural environment testing.Laboratory Tes
The international status of China's fasteners has continued to strengthen over the past few years. China has quickly become one of the world's largest producers and exporters of fasteners.Chinese fastener manufacturers are committed to improving product quality, complying with international standard
A spiral point self-drilling screw is a type of fastener that drills its own hole and forms threads as it is driven into a material. What sets it apart from other self-drilling screws is its unique spiral point at the tip that helps to reduce the torque required to drive the screw and allows for fas
A decking screw is a type of screw designed for use with decking materials such as wood, composite lumber, or PVC. Decking screws are typically made of corrosion-resistant materials, such as stainless steel, and are designed to be long enough to penetrate the decking board and into the supporting jo
A stitching screw is a specialized type of self-tapping screw that is designed to attach two metal sheets together without the need for pre-drilling a hole. It features a sharp point, a narrow shank, and a wider thread, which allows it to pierce through the top sheet of metal and then thread tightly
Ruspert coating is a type of surface coating that provides corrosion resistance and enhanced durability to metal surfaces. It is a combination of a base coating and a topcoat, typically consisting of a zinc or zinc-alloy base layer and a ceramic or organic topcoat.The base layer of Ruspert coating i
Hydrogen embrittlement is largely unpredictable, and efforts to avoid it must start at the design stage to determine the characteristics of the part and the subsequent manufacturing process.Avoiding hydrogen generation during manufacturing and hydrogen absorption by fasteners eliminates the risk of
A4 is equivalent to American standard 316L stainless steel and equivalent to my country's 0Cr17Ni12Mo2 stainless steel. 0Cr17Ni12Mo2 austenitic stainless steel is suitable for use in seawater and other media. It is mainly used as a pitting corrosion resistant material. It is used in photography, foo
Typical fastener hydrogen embrittlement occurs in carbon steel and alloy steel materials.The hardness of fasteners is a core parameter. When most standards talk about hydrogen embrittlement, they will point out that the risk of hydrogen embrittlement begins when the hardness exceeds 320HV. Some expe
Zinc-aluminum coated structure:1st metal zinc layerThe second layer of high corrosion resistance chemical film layerThe third layer is made of ceramic materialsThe anti-rust performance of zinc-aluminum coating is different from the general surface treatment of a single material, but the multiplicat
What is a dual hardness drill end screw?The dual-hardness drill tail screw is made of alloy steel, and adopts a segmented heat treatment method to make the bearing part of the screw have stronger toughness, and at the same time make the drill bit and threaded part have greater hardness to achieve st
NSSC550 (13Cr-2Ni-2Mo) is a product of martensitic (M) series stainless steel with high hardness and high corrosion resistance independently developed by Nippon Steel & Sumitomo Metal.Properly quenching and tempering this steel can obtain extremely high strength and hardness of 0.2% yield strength 1
