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.

传统的护栏使用铁条、铝合金材料，需要借助电焊等工艺技术，而且质地较软、容易生锈、色彩单一。锌钢护栏地解决了传统护栏的缺点，而且低廉，成为传统阳台护栏材料的替代产品。

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

铁艺护栏由基材和配件组成。

Iron guardrail is composed of base material and accessories.

铁艺护栏型材 铁艺护栏的基材为高温热浸锌材料，热浸锌是指把钢材投入几千度的锌液池中，浸泡达一定时间以后锌液就会渗透到钢材中，使之形成一种特殊的锌钢合金，热浸锌材料表面不经任何处理在野外环境中即可达30年不锈蚀，如：高速公路护栏、高压电塔都是采用高温热浸锌材料，其防锈长达30年之久，彻底解决了多年来防锈、美观与之间的问题。

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.

铁艺护栏配件采用使用寿命可达50年之久的改性高强度工程尼龙，其强度、硬度远高于普通钢制材料，每可承受183MPA以上的压力，2729MPA的拉伸力，可承受220℃以下高温不变形等优点。

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.
