Hot-dip galvanizing is a long-term, stable and very effective anti-corrosion treatment method for highway anti-collision corrugated guardrails. The anti-corrosion life of guardrails treated with this method is also very long, generally up to 15-30 years. The years vary, so the use of this method for anti-corrosion is also a commonly used anti-corrosion method by various corrugated guardrail manufacturers at this stage.
Corrugated guardrail highway corrugated guardrail panels can be divided into Class A and Class S according to the anti-collision level. S-class guardrails are reinforced types and are suitable for use on particularly dangerous sections of roadside, while A-class guardrails are used on dedicated highways. Commonly used roadside corrugated beam guardrails can be divided into five levels: B, A, SB, SA and SS according to the anti-collision level. Anti-collision guardrail highway corrugated guardrail panels are the main form of semi-rigid guardrails. It is a continuous structure made of corrugated steel guardrail panels spliced to each other and supported by columns. The corrugated guardrail has been exposed to the outdoor environment for a long time and is exposed to wind, sun and rain every day. A good anti-corrosion treatment method can greatly extend the service life of the corrugated guardrail.
So, specifically, what are the benefits and advantages of hot-dip galvanizing for corrugated guardrails?
First of all, in terms of treatment costs, the hot-dip galvanizing process is more effective and less expensive than using other paint coatings for anti-corrosion treatment. In fact, if the hot-dip galvanizing anti-corrosion process has a longer service life, it also means that the maintenance cost of the guardrail is reduced. In addition, it saves time and effort. The galvanizing process is more convenient and faster than coating. After the galvanizing process is completed, the corrugated guardrail does not need to be painted after the installation is completed, which saves even more time.
