There are many types of guardrails on the market. According to the material, they can be roughly divided into zinc steel guardrails, aluminum guardrails, iron guardrails, wooden guardrails, plastic steel guardrails, etc. Each guardrail has its own performance characteristics and application scenarios. In terms of service life, corrosion resistance, rigidity and other properties, zinc steel guardrails have obvious advantages. In order to let everyone better understand the performance characteristics of zinc steel guardrails, the editor will introduce to you the performance of zinc steel guardrails.
1. Strong rigidity and strong impact resistance
The hardness of zinc steel, the base material of zinc steel guardrails, can reach 211DNP, which is 1/3 stronger than 159DNP of ordinary steel, and has strong rigidity. In addition, the steel pipe has good flexibility and strong impact resistance. It can withstand an impact of 50gkg per square centimeter. Therefore, it is widely used in road guardrails and has strong safety protection properties. When an accident occurs, it can be easily Intercept the accident vehicle properly to prevent the accident from expanding its impact.
2. Excellent corrosion resistance
Zinc steel guardrails also have strong anti-corrosion properties. Its unique hot-dip zinc three-in-one anti-rust protection is a zinc steel production process for high-end European cars, which can guarantee no rust for thirty years. The surface coating adopts the American DuPont coating process, which can resist ultraviolet rays, has strong anti-corrosion and anti-rust capabilities, and can ensure that the color change does not exceed 15% in 15 years, ensuring its service life. Quick assembly without welding to avoid welding rust and improve anti-corrosion performance.
3. Good self-cleaning performance and various colors
The surface of the zinc steel guardrail is electrostatic spray paint, which is smooth and dust-free, and has good self-cleaning properties. It only needs rainwater and water gun spraying to make it as bright as new, saving maintenance costs and having strong appearance after long-term use. Different from the single color of other guardrails, the colors of zinc steel guardrails can be matched at will, with rich colors and excellent decorative properties.
4. Assembly design, quick installation
Assembly design makes installation quick and easy, improving installation efficiency and saving installation costs. Using the buried installation method and the installation of footing boards can save building foundation costs, save land resources, and improve the cost performance of guardrails.
5. Long service life
Because of its excellent anti-corrosion properties, strong rigidity, good toughness, and impact resistance, it solves the short-term problems of traditional guardrails such as corrosion, powdering, and cracking, and extends its service life. The seven-stage pre-treatment and coating process can ensure that the zinc steel guardrail can be used for 50 years with confidence.
6. Security attributes
In order to improve the safety of the guardrail, stainless steel safety bolts are added with an anti-theft design to avoid safety risks and eliminate worries.
