With the improvement of people's living standards, people pay more and more attention to the importance of safety, safety is more important than Taishan, safety above all else. At the same time people pay attention to safety at the same time, also concerned about the beauty of the environment, and capital investment, and strive to get a smaller investment through the relatively large return. For example, the relatively new product of the safety fence has gradually replaced the traditional brick and concrete structure of the wall, especially for some enterprises, schools or companies, this is a very scientific and rational choice. So what are the advantages of these safety fences?
People have been considering a question of price, the same price to see the quality, the same quality to see the price. Over the past two years, the price of the market has just declined, the cost of these steel fence significantly reduced, so the price of the product has fallen to a very low position, iron fence than the brick wall has a considerable advantage. There is a safe fence can effectively adapt to a variety of terrain, for some low-lying terrain, iron fence can easily deal with, and ordinary brick wall is actually the foundation of the processing fee some brains. Then there is aesthetics. Iron fence perspective effect, can effectively increase the width and breadth of the field of vision, which is unmatched by ordinary walls. In addition, the iron fence can design a variety of shapes, and durable, while the iron fence for the overall demolition and transportation, after the demolition will not affect the secondary use.
For some special environments, such as the relatively humid areas of the terrain, the traditional brick wall is easy to corrosion to the foundation, then we can use stainless steel structure of the fence, can effectively avoid the occurrence of corrosion. So, iron fence has been a considerable number of advantages, cost is quite high.
On the fence, China is usually used early painting protection, and later gradually use the form of hot dip zinc, is still widely used in a large number of hot dip zinc protection. Fence fence of the national standard GB / T18226-2000 "highway traffic engineering steel components anti-corrosion technical conditions", the fence product protection is divided into four categories: galvanized, aluminum, galvanized (aluminum) after painting, The In areas where the countryside and pollution are not serious, separate hot dip zinc protection or separate spray protection fences can be used. In heavy industrial or coastal urban areas, especially in areas where acid rain is used, ordinary hot dip zinc or spray Layer fence can reach the usefulness of the useful life, resulting in fence maintenance costs greatly increased. For the hot-rolled fence, its corrosion resistance than ordinary galvanized fence, but its technology, technology, cost and environmental impact and other reasons, the scope of application is not very wide. The use of hot dip + spray protection system, relative to the hot dip zinc + spray protection system is an uneconomical method. The use of galvanized sheet + spray double protection system, in heavily polluted areas, especially acid rain areas to achieve better anti-corrosion effect, the use of life greatly extended, the most durable protection methods. Different materials of the road fence, have different uses and advantages, for the application of the fence we need to combine the advantages of materials to choose.
