Stainless steel wire mesh is more common as a fence net. Note that there are categories when using. It is different according to the material or the weaving method.
There are several methods to distinguish the material of stainless steel wire mesh:
1. Stainless steel wire mesh can be distinguished from toughness. The toughness of 304 is better. 201 is harder and more brittle than 304. Experiment with a hard blade. There will be obvious scratches on the surface of 201, and the surface of 304 No visible scratches.
2. Stainless steel wire mesh can be acid and alkali resistant. 201 is not as good as 304 because of its relatively low nickel content. 3. In terms of corrosion resistance, stainless steel wire mesh, because 201 contains manganese, will rust for a long time in a humid or high salt environment, and 304 does not contain rust because it does not contain manganese.
4, stainless steel wire mesh can be seen from the color, because 201 stainless steel contains manganese element color will be darker than 304, and 304 should be whiter and brighter.
Stainless steel wire mesh fence
Stainless steel wire fence fence column spacing; due to reduced height, it is recommended that the column spacing be set from 4m to 5m, then 201 per kilometer; if set to 4m, 251 per kilometer, which means 50 per kilometer saved Upright. Fences and barbed wire of fence nets are frequent in the vicinity of villages and towns in rural areas. Metal nets or steel nets should be used for the nets. Therefore, the type of net is not harmful to people. The design should use the lower dense (0 ~ 60cm high) 10 × 15cm holes and the upper sparse (60 ~ 120cm high) isolation network 20 × 30cm holes, so as to achieve the purpose of saving materials and cost. However, because the cost of expanded steel mesh is higher than that of metal mesh, and its aesthetics is also slightly worse, and its adaptability to complex terrain is relatively weak, currently it is rarely used on domestic highways. There are three types of metal meshes: woven mesh, welded mesh, and drawn flower mesh. Welded mesh is more commonly used. There are two types of welded mesh: rolled mesh and sheet mesh. Due to the simple installation of the rolling net, high overall strength, and strong adaptability to complex terrain (the mesh can be cut at will), it is recommended to use the rolling net in general design. Barbed wire fences are cheaper in mountainous, forested, and pastoral areas because barbed wire is less expensive. Barbed wire should be used. According to the requirements of highway maintenance technical specifications and actual needs, technical inspections and dredging of bridges and culverts are carried out regularly and irregularly every year. In order to maintain the management personnel to enter and exit the fence net to carry out regular inspections of bridges and culverts, doors on both sides of the bridge and the culvert should be provided for easy opening. There are two types of doors: single and double doors. Equipment and vehicles enter and exit, corresponding steps are set up for people to get on and off.
