In the daily use of collision guardrails, the use of W-beam guardrail is the most widely used. W-beam guardrail can be used for highway anti-collision bar, general road (provincial road, county road, township road, etc.) anti-collision fence, factory area, construction site, forest park and other protective isolation, as well as farm construction.

orrugated guardrail posts are made of hot galvanized columns with the plate, and wooden post is used as columns. Shiteng post is the hot galvanized post. With the development of the technology, the shape of the column of the corrugated guardrail is also diversified. Normally the W - beam guardrail use round post

he surface of the corrugated guardrail is divided into two forms, hot galvanizing and plastic sprayed . Spray-plastic guardrails are sprayed on the product on the basis of hot galvanizing, which is better than ordinary hot galvanizing for the anti-corrosion effect, and also has a beautiful effect. The anti-corrosive age of ordinary hot galvanizing is about 20 years, but after it is sprayed, it can reach 30 years of anti-corrosion. This is more suitable for rainy, windy and seaside areas.

A principle of hot dipped galvanized: galvanized iron to clean clean, then solvent treatment, drying after immersed in liquid zinc, iron and zinc layer of molten zinc reaction produce an alloying, the process for degreasing, washing, pickling, helps the plating - drying - hot dip galvanized, separation, cooling passivation.

The safety roller barrier adopts "one post with 4 columns", which can effectively prevent the car from passing the barrier and drive out of the road by strengthening the performance and installation of columns and guardrails.
