1. The advantage of this product is the triple superposition of surface treatment+structural design+functional properties, which is different from nylon isolation column, two-way isolation column and black zinc isolation column, and adapts to more industrialized and batch fastening requirements
2. The exclusive advantages of blue-white zinc surface treatment (the substrate is mostly carbon steel, and the performance is greatly improved after blue-white zinc)

   Cost-effective anti-rust and anti-corrosion: Blue-white zinc is a high-end type of electro-galvanizing. The coating is compact and uniform, with passivation treatment. The neutral salt spray test can reach 48-96 hours. In indoor, dry outdoor and slightly humid environment, the anti-rust performance far exceeds that of untreated carbon steel, and the cost is only 1/3-1/2 of that of 304 stainless steel isolation column. It is the first choice for cost-effective anti-rust scheme.

3. The coating has strong adhesion and wear resistance: the blue-white zinc coating has excellent adhesion with carbon steel substrate, and it is not easy to fall off and scratch during installation and disassembly; At the same time, the hardness of the coating is moderate, which can bear certain friction and collision and prolong the service life of the isolation column.
4. Adapt to a variety of installation requirements: the one-way structure can be designed as external thread one-way (screwing in the base plate to support the upper plate), internal thread one-way (fixing the upper plate with screws to isolate the base plate from the upper plate), one end with external teeth and one end with polished rod (precise support, no thread interference) according to customer requirements, which is suitable for different connection modes between plates and has strong versatility.

1. Supporting scheme recommendation: It is recommended that the blue-white-zinc one-way isolation column+blue-white-zinc cross-groove pan head screw+blue-white-zinc flat gasket be used to realize the "all-blue-white-zinc fastening system", which greatly improves the antirust performance, connection reliability and installation efficiency, and increases the customer unit price; For precision equipment, blue-white-zinc single-pass isolation column and nylon anti-loosening gasket can be recommended, taking into account the requirements of rust-proof, anti-loosening and anti-scratch substrates.
2. Tips for substrate adaptation: this product is most suitable for carbon steel substrates, metal plates, circuit boards and other substrates, and can realize accurate isolation and support between plates; If customers need to connect plastic substrates, they can recommend matching blue, white and zinc tapping screws to achieve more reliable connection.
