Cold galvanized chain link fence chain link fence accounted for the vast majority of the production of proportion, made of high quality cold galvanized low carbon steel wire hook and weaving, detailed below cold galvanizing process. I. Overview of cold galvanizing cold galvanizing process used to protect metals against corrosion, for use of the zinc coating filler, using any kind of coating method to be applied to protect the surface, forming a zinc coating after drying filler , having a content of zinc in the dried coating (95%). Suitable for repair work (ie work in the repair process, the only place to be protected in the steel surface damage, as long as you can re-fix surface coating). Cold galvanized steel products for a variety of processes and structures of corrosion. Second, the construction process of the cold galvanizing cold galvanizing paint primarily through electrochemical principles to corrosion, it is necessary to ensure full access to zinc and steel, generating electrode potential difference, so the steel surface treatment is very important. 1. steel surface treatment before (a) new steel surface treatment of cold galvanizing spray, you should choose a mechanical descaling (sand blasting, shot blasting, etc.), the steel surface cleanliness achieve ISO 85O1-1 Sa 2.5 grade equivalent GB 8923 Sa 2.5 magnitude. Its text is defined as: "After the steel after mechanical descaling, surface no oil, no rust, scale and other dirt, or only slight traces remain; 95% of the steel surface by steel shot (sand) impact, exposing metallic sheen "For another indicator of the quality of the surface treatment - - roughness, different cold galvanized materials require different roughness. Zinc plus (Zinga) construction description, requires an average roughness Ra = 12.5, i.e. roughness Rz = 55 ~ 75 micrometers. In the "strong zinc" and "Luo Balu" construction specification, the requirements of slightly lower roughness, Rz = 40 ~ 60 m. If the cold galvanizing film alone, as the anti-corrosion coating, the surface roughness can be controlled a little smaller, to ensure that cold galvanized coating thickness; and when cold galvanizing as the underlying anti-corrosion coatings, the total matching coat When the thickness is larger than 180 microns, to ensure that the entire coating adhesion, the steel should be greater than the surface roughness Rz of 60 microns. Diamond Fence Material PVC wire, stainless steel wire, high-quality low-carbon steel wire, galvanized wire, wire and other name is called: Press called into: chain link fence, diamond mesh, rhombic mesh, ring networking, chain network, hook net, steel mesh, fence, fence net farming, active network. Press Finish: Galvanized - chain link fence, galvanized - chain link fence, PVC coated chain link fence (pvc, pe plastic bag), dip chain link fence, chain link fence spray. By Application: Decorative chain link fence, chain link fence, chain link fence protection Another classification: stainless steel chain link fence (material 201,302,304,304L, 316 and so on without surface treatment). Material: Low carbon steel wire (wire), stainless steel wire, aluminum alloy wire. Weaving and characteristics: mesh uniform, flat surface, weaving simple, crochet made, beautiful; mesh quality, web wider, thicker wire diameter and difficult to corrosion, longer life, and practical. Diamond fence main purposes: diamond fence widely used in highway, railway, highway fence facilities. Also used for indoor decoration, raising chickens, ducks, geese, rabbits and zoo fence. Mechanical equipment, protective nets, machinery and equipment transport network. Stadium fence, the road green belt protection. The screen in the production of a box-shaped container, fill with rocks and other cage, become gabion. Also used to protect and support the seawall, hillsides, road and bridge, reservoirs and other civil works. Flood control and flood of good material. Can be used for the manufacture of handicrafts. Warehouses, cold storage room tools, protective reinforcement, marine fishing fence and construction sites, rivers, slope fixed soil (rock), residential security protection. Also known as coal mine safety net mesh stent, the stent mesh; material of high quality low carbon steel wire welded row. General Specifications: 1mx2m mesh 10cmx10cm, mining production is Mine Road off the top, pouring metal mesh safety products. Uses: used in coal roadway safety, coal stent mesh weave bilateral, reliable connection, the same type, protective and strong, easy construction, security, high performance, is China's coal mine safety department as mine roadway Private Network Protection; some customers misuse hook Fence as a safety net to use, easy to deform the mesh network, the connection is not strong, the safety factor is far below the coal stent net. Note: Other specifications can be customized according to customer requirements
