Waveform fence is also known as wave board fence, guardrail, W board fence, road barrier. Its English name for ☆☆ corrugated beam barrier ☆☆. Bridge is currently the most widely used at home and abroad security fence.

Waveform guardrail Category: General by setting beam guardrail and crash location to the classification rating. Press to set the location can be divided into a roadside fence and the central median barrier. A crash can be divided by grade level and the S-Class. S-Class fence belongs enhanced for particularly dangerous sections of road side use, A grade for private roads. Material: high quality steel embalmed. Manufacturing process: high quality steel pickling, stamping or three pairs wave-wave plate, after doing galvanized or hot-dip galvanizing spray. Product Features: Good corrosion resistance, anti-aging, beautiful, simple and quick installation. Purpose: industrial, agricultural, municipal, transportation and other sectors of the fence, decorative, protective and other facilities.
