1 Introduction high-speed crash barrier is the main form of semi-steel fence, which is a kind of corrugated steel fence plates are spliced ??by the main pillar supporting the continuous structure. It uses the soil base, column, beam deformation to absorb impact energy and force out of control of the vehicle changes direction and returns to the normal direction of travel of the vehicle out of the road to prevent the outside to protect the vehicle and passengers, to reduce the loss caused by the accident. Steel beam guardrail soft phase and, with a strong ability to absorb collision energy, with better sight inducing function, can be coordinated with the road alignment, appearance, can be used on a small radius corners, damaged at easily replaced. You can use a combination of beam guardrail on a narrow median strip. Division 2 Color: galvanized silver, spray green, white, blue and so on. Press the waveform can be divided into three double waveform waveform fence and fence. Press the spray surface treatment is divided into two galvanized guardrail and galvanized. Press to set the location can be divided into a roadside guardrail and central median barrier. A collision can be divided by grade level and the S-Class. S-Class fence belongs enhanced for roadside use of particularly dangerous sections, A-level for the private road. Common roadside beam guardrail crash level can be divided by B, A, SB, SA, SS five. Specifications dual waveform fence panels: 4320mm × 310mm × 85mm × 3mm / 4mm three waveform fence panels: 4320mm × 506mm × 85mm × 3mm / 4mm dual waveform divider plate column: 114mm / 140mm × 4.5mm × height; three waveform fence panels Column: 114mm / 140mm × 4.5mm × height; column spacing: divided into 2 m spacing and 4 m spacing; Connection: Connection column and the board have Fangzu block (abalone board supporting) and the bracket-style (ten holes board) two. Dosage: wave guardrail standard segment column spacing 4 m per kilometer by 250 plates, 250 columns, ends 2, column caps 250, Fangzu block 250, the connecting bolts M16 × 170/42 250 units, splice bolts M16 × 35 2000 sets. 4 uses the characteristics of the highway, one, two highways and provincial roads, county roads and rural roads area, large parking facilities and other safety crash. That increases the bending wave guardrail appearance, while increasing the intensity steeplechase, both ways; automatic production line extrusion, surface clean no damage, corrosion resistance strong; surface treatment mature; corrosion, aging, sunscreen , high resistance, low temperature and other characteristics, outdoor life of up to 10-25 years environment; concise product structure, beautiful and practical, easy to good transportation, installation, anti-theft performance, little affected by the actual terrain for the mountain, slope, bending zone Adaptability is particularly strong, moderate cost, suitable for large-scale use.
