1. Outstanding mechanical function. Because the two layers in the watch are made of metal materials, they have strong compressive and impact resistance, high tensile strength, high elongation, high modulus of elasticity and small coefficient of thermal expansion.
2, heat and cold, hot and cold. The working temperature of the hot-dip galvanized guardrail material can reach 700 °C ~ 1035 °C. Cold resistant up to 1 Kelvin (B273 ° C). Therefore, the hot-dip galvanized guardrail has a good heat-resistant and cold-resistant function, and it is still winter in summer, and it is suitable for both hot and cold.
3. Under the effect of mechanical force, the hot-dip galvanized guardrail will make the galvanized steel pipe to be reduced in diameter, and the inner stainless steel pipe will be expanded to make the two layers of raw materials closely related, and the contact strength exceeds the national standard rule of 1 mpa or more. Because the surface of the surface is near the raw material, there is no fragmentation.
4. Clean and environmentally friendly and safe. Because the chemical function of the hot-dip galvanized guardrail is stable and harmless to the human body, the hot-dip galvanized guardrail is clean and environmentally friendly, and has good safety, which meets the needs of the “ecological residence” and the people-oriented concept.
5, rust and corrosion resistance is good. The hot-dip galvanized guardrail material has superior rust and corrosion resistance than other raw materials because of its chemical functions such as rust prevention, oxidation resistance, acid and alkali resistance, and intergranular corrosion resistance.
