The iron fence, which has been widely used, is prone to rust. The rust stains from the corrosion of wind and rain will cause permanent pollution to the fence and will be maintained annually at a high cost. All kinds of disadvantages upset people. What is the best fence that people need?
The zinc steel fence just caters to the huge demand of the shopping mall, and complies with the direction of the development of the shopping mall. Zinc steel fences for enterprises and institutions, zinc steel fences for residential quarters, zinc steel shutters for high-rise buildings, air-conditioning fences for villas, squares, bridges, urban greening protection and highway isolation belts can be used. Generally speaking, there is a demand for zinc steel fence in the locality where people live, and the accompaniment of zinc steel fence is needed in the construction projects.
锌钢护栏的特色 ：价廉 因为铸铁涨价，铁艺产品的加工成本越来越高，商场价格居高不下。锌钢防护栏因为制造通过几十道工序，色彩鲜艳，坚持几年都不生锈，并且拼装简略不需求焊接，对于锌钢护栏来说，这是个很大的优势。各城市开发区楼盘迅猛发展，旧城的翻新改造，企事业单位的搬家，各种出产经营企业的建设，房地产的开发，都给锌钢护隔离栏出产企业带来巨大的商机。 锌钢护栏为什么会生锈当锌钢护栏管外表呈现褐色锈斑（点）的时候，人们大感惊讶：以为 “锌钢护栏是不易生锈的，生锈就不是锌钢护栏了，可能是钢质呈现了问题”。其实，这是对锌钢护栏缺少了解的一种片面的过错看法。锌钢护栏在一定的条件下也会生锈的。锌钢护栏具有反抗大气氧化的才能---即不锈性，一起也具有在含酸、碱、盐的介质中乃腐蚀的才能---即耐蚀性。但其抗腐蚀才能的巨细是随其钢质本身化学组成、加互状况、使用条件及环境介质类型而改变的。锌钢护栏是其外表构成的一层极薄而坚固细密的安稳的富铬氧化膜（防护膜），避免氧原子的持续进入、持续氧化，而获得抗锈蚀的才能。一旦有某种原因，这种薄膜遭到了不断地损坏，空气或液体中氧原子就会不断进入或金属中铁原子不断地析离出来，构成疏松的氧化铁，金属外表也就受到不断地锈蚀。这种外表膜受到损坏的方式许多，日常日子中多见的有如下几种：
Characteristic of Zinc Steel Guardrail: Low price because of the increase in cast iron, iron products processing costs are increasing, market prices remain high. Zinc steel fence because of the manufacturing process through dozens of bright colors, adhere to a few years no rust, and assembly simple welding is not required, for zinc steel fence, this is a great advantage. The rapid development of various urban development zones, the renovation and transformation of the old city, the relocation of enterprises and institutions, the construction of various production and operation enterprises, and the development of real estate have brought enormous business opportunities to the production enterprises of zinc steel barriers. Why does the zinc steel guardrail rust when the appearance of the zinc steel guardrail pipe brown rust spots (spots), people are surprised: think that "zinc steel guardrail is not easy to rust, rust is not zinc steel guardrail, may be a problem of steel." In fact, this is a one-sided view of the lack of understanding of zinc steel guardrail. Zinc steel guardrails will rust under certain conditions. Zinc steel barriers have the ability to resist atmospheric oxidation - - that is, stainless, together with the ability to corrode in an acid, alkali, salt medium - - that is, corrosion resistance. However, the size of its corrosion resistance ability varies with the chemical composition of the steel itself, the state of addition and interaction, the use conditions and the type of environmental media. Zinc steel guardrail is a very thin and solid thin and stable chromium-rich oxide film (protective film), which can avoid oxygen atoms continuously entering and oxidizing, and obtain the ability to resist corrosion. Once for some reason, the film is constantly damaged, oxygen atoms in the air or liquid will continue to enter or iron atoms in the metal will continue to separate out, forming a loose iron oxide, the metal surface will be constantly corroded. There are many ways to damage the outer membrane.
1。 Organic juice (such as melon, vegetable, noodle soup, phlegm, etc。) is adhered to the surface of zinc steel guardrail, which forms organic acid in the presence of water and oxygen, and corrodes the metal surface in the long run。
2. There are dust or other metal particles attached to the zinc steel guardrail. In the humid air, the condensed water between the attachment and the zinc steel guardrail connects the two into a micro-battery, which triggers the electrochemical reaction and damages the protective film. It is called electrochemical corrosion.
3. In polluted air (such as atmosphere containing a lot of sulfides, carbon monoxide, nitric oxide), when encountering condensate, it forms sulfuric acid, nitric acid, acetic acid liquid point, causing chemical corrosion.
4.锌钢护栏外表粘附含有酸、碱、盐类物质（如装饰墙面的碱水、石 灰水喷溅），引起部分腐蚀。 锌钢护栏做为一种代替商场传统不锈钢防护窗的第三代产品，它已耐腐蚀强，色彩丰富，外观精巧，超高强度，价格适中等更多优势而深受顾客喜爱。
4. The external adhesion of zinc steel guardrail contains acid, alkali and salt substances (such as alkaline water and lime water splashing on decorative walls), causing partial corrosion. Zinc steel guardrail as a substitute for the traditional stainless steel protective window in shopping malls of the third generation of products, it has strong corrosion resistance, rich color, exquisite appearance, ultra-high strength, moderate price and more advantages by customers.
5。 Selection of the popular combination of cross-linking process, any joints are selected high-strength modified engineering nylon joints, without welding, to ensure that the substrate is not damaged, enhance anti-rust ability
6. The properties of high strength modified engineering nylon joints, such as anti-ultraviolet, anti-oxidation, anti-saline-alkali, weather and fog resistance, far exceed the first-class specifications of national guardrail joints.
7. Zinc steel profile is made by punching. It can be manufactured directly after punching when leaving factory. The device is convenient, simple, labor-saving and time-saving, and avoids the trouble of punching before.
