Jinan Tieyi guardrail refers to the zinc steel fence made of zinc alloy material. Due to its high strength, high hardness, exquisite appearance, bright color and other advantages, it has become the mainstream product used in residential areas and field fences.

傳統的護欄使用鐵條、鋁合金材料，需要借助電焊等工藝技術，而且質地較軟、容易生銹、色彩單一。鋅鋼護欄完美地解決了傳統護欄的缺點，而且價格低廉，成為傳統陽臺護欄材料的替代產品。

Traditional guardrails use iron bars and aluminum alloy materials, which need the help of welding and other technology, and have soft texture, easy to rust and single color. Zinc steel guardrail perfectly solves the shortcomings of traditional guardrail, and the price is low. It has become an alternative to traditional balcony guardrail materials.

（一）材料

（1） Materials

鐵藝護欄由基材和配件組成。

Iron guardrail is composed of base material and accessories.

鐵藝護欄型材 鐵藝護欄的基材為高溫熱浸鋅材料，熱浸鋅是指把優質鋼材投入幾千度的鋅液池中，浸泡達一定時間以后鋅液就會滲透到鋼材中，使之形成一種特殊的鋅鋼合金，熱浸鋅材料表面不經任何處理在野外環境中即可達30年不銹蝕，如：高速公路護欄、高壓電塔都是采用高溫熱浸鋅材料，其防銹長達30年之久，徹底解決了多年來防銹、美觀與安全之間的問題。

The base material of iron guardrail profile iron guardrail is high-temperature hot-dip galvanizing material. Hot dip galvanizing refers to putting high-quality steel into a zinc bath with thousands of degrees. After soaking for a certain time, the zinc will penetrate into the steel to form a special zinc steel alloy. Without any treatment, the surface of hot-dip galvanizing material will not rust for 30 years in the field environment, such as highway guardrail High voltage electric towers are made of high-temperature hot-dip galvanized materials, which have been rustproof for 30 years, completely solving the problems between rust prevention, beauty and safety for many years.

鐵藝護欄配件采用使用壽命可達50年之久的改性高強度工程尼龍，其強度、硬度遠高于普通鋼制材料，每平方米可承受183MPA以上的壓力，2729MPA的拉伸力，可承受220℃以下高溫不變形等優點。

Iron guardrail accessories adopt modified high-strength engineering nylon with a service life of up to 50 years. Its strength and hardness are much higher than ordinary steel materials. It can withstand the pressure of more than 183mpa and the tensile force of 2729mpa per square meter, and can withstand the high temperature below 220 ℃ without deformation.

１、鐵藝護欄工藝：采用無焊連接、橫豎穿插組裝而成。相對于傳統的鐵藝護欄，安裝更加快捷，外表更加美觀。

1. Iron guardrail Technology: it is assembled by non welding connection and horizontal and vertical interspersed assembly. Compared with the traditional iron guardrail, the installation is faster and the appearance is more beautiful.

２、鐵藝護欄的基材由六層組成，分別是：

2. The base material of iron guardrail consists of six layers:

(1)鋼材層(Base steel)：基材，硬度值為159DPN；

(1) Base steel: base material with hardness value of 159dpn;

(2)鋅鋼合金層(Zeta layer)：更靠近基材的一層致密合金層，構造復雜，耐腐蝕性極強，以FeZn7及FeZn13化合存在，硬度值為211DPN，含Fe為7%-11%；

(2) Zinc steel alloy layer: a dense alloy layer closest to the substrate, with complex structure and strong corrosion resistance. It exists in the combination of fezn7 and fezn13, with hardness value of 211dpn and Fe content of 7% - 11%;
