Hot dip galvanized spray coated guardrail

Dalian Fantai General Equipment Co., Ltd.'s series of products, including hot-dip galvanized spray molded new guardrails, balcony guardrails, staircase handrails, etc., have advantages such as waterproofing, acid and alkali resistance, corrosion resistance, natural aging resistance, and paint free maintenance. They are brightly colored, bright, and modern in design, with a service life of more than 20 years. They have broad market prospects and can be widely used for walls, flower beds, lawns, gardens, municipal engineering, roads, and other buildings in villas, courtyards, factories, and other areas Parking lots, lakesides, balconies, and other places.

（1） Materials used

The base material for zinc steel guardrails is hot-dip galvanized material in extremely hot weather. Hot dip galvanizing refers to the process of putting high-quality steel into a zinc liquid pool at several thousand degrees Celsius, and after soaking for a certain period of time, the zinc liquid will penetrate into the steel, forming a special zinc steel alloy. The surface of hot-dip galvanized material can be rust free for 30 years in the outdoor environment without complete treatment. For example, highway guardrails and high-voltage electric towers use hot-dip galvanized materials in extremely hot weather, Its rust prevention has lasted for 30 years, completely solving the problem of rust prevention, aesthetics, and safety that has existed for many years.

The zinc steel guardrail accessories are made of modified high-strength engineering nylon with a service life of up to 50 years. Its strength and hardness are much higher than those of ordinary steel materials. It can withstand pressure of 183MPA or more per square meter, tensile force of 2729MPA, and can withstand hot weather below 220 ℃ without deformation.

（2） Craftsmanship

1. Zinc steel guardrail technology: It is composed of welded joints and assembled horizontally and vertically. Compared to traditional iron guardrails, installation is faster and the appearance is more beautiful.

2. The base material of zinc steel guardrail consists of six layers, namely: (1) Steel layer (Base steel): The base material has a hardness value of 159DPN; (2) Zinc steel alloy layer (Zeta layer): A dense alloy layer near the substrate, with a complex structure and strong corrosion resistance. It exists in the combination of FeZn7 and FeZn13, with a hardness value of 211DPN and a Fe content of 7% -11%; (3) Delta layer: Clearly a monoclinic columnar structure with a Fe content of 6%, non-toxic, corrosion-resistant, and a hardness value of 179DPN; (4) Pure zinc layer (Eta layer): dense hexagonal crystal system, not easily broken during deformation and processing, zinc purity of 98.5%, hardness value of 70DPN; (5) High zinc phosphating layer: has excellent corrosion resistance and enhances the adhesion between the coating and the substrate; (6) Aksu Nobel Color Ionic Molecule Curing Layer in Hot Weather: Excellent anti-corrosion and impact resistance, with UV resistance, oxidation resistance, and surface self-cleaning properties, with a color change rate of no more than 5% in 15 years.

2、 Characteristics

Zinc steel guardrails have the following characteristics:

1. The assembly design without welding ensures quick and simple installation.

2. Four layer anti-corrosion treatment, with a service life of more than 20 years, solves the problems of traditional products such as rust, powdering, and cracking in a short period of time, and eliminates the cost of product maintenance and renewal.

3. Excellent decoration, rich colors, and meeting the personalized needs of different customers for the product.

4. Environmentally friendly, non polluting, and solves the problem of building pollution caused by common products.

5. Very good flexibility performance, the rigidity and flexibility of the substrate make the guardrail product have good impact resistance.

6. The surface treated by the electrostatic spraying imitation Tang porcelain process gives the guardrail product excellent self-cleaning performance. It can be smooth and new after being washed by rainwater and sprayed with a water gun.

7. The buried installation method and foot plate installation not only save your building foundation costs but also save land resources.

8. Very good weather resistance, salt spray resistance, and moisture and heat resistance, suitable for use in different regions.
