Cable Guardrail Barriers - China

Cable guardrail barrier system is a flexible guard railing system to provide good safe guard in open areas.

This barrier system composed with chiefly hot dipped galvanized steel wire strands, steel posts and terminals offering excellent rust resisting and corrosion resisting property.

This type of wire rope safety barrier is a kind of highway fence keeping vehicles within the limits of correct way.

The wire cable barrier is made with three, four, five or six high tensile steel wire ropes, firmly mounted on the steel post at certain spacing to form a flexible guard barrier.

The more number of the wire cables, the much strength the barrier offers.

Compared to the corrugated steel highway guardrail beams, the cable barrier costs less and the installation is much easier.

It serves as an effective high barrier for absorbing most sudden impact energy during collision and also for redirection of errant vehicles.

Compared with beam guardrails, using wire cable barrier offering the following benefits:

Less metal material used, low cost;

Easy to install and repair;

Cable tension can be adjusted by changing of wire cable numbers and spacing;

Post space can be adjusted;

Work effectively;

Good looking for open scenic spots.

Three Major Factors Determining the Efficiency of Cable Barriers:

First, cable numbers:

Three of four cables are commonly used.

Five or six layer wire cables are used for reinforced guard railings.

Generally, more cables, the higher ability to redirect the errant vehicles.

Second, spacing of wire cables and posts:

The barrier post often installed with spacing from 6.3 to 32.6 ft.

The longer spacing normally means the higher deflection distance.

Thirdly, tensioning:

Cables are fixed on the post and tightened to specific tension in accordance with the local temperature and environment.

After tensioning, the reflection will be reduces and the ability to preventing vehicles from skidding off the road can be enhanced.

Normally the tensions values range approximately from 2, 000 to 9, 000 lb.

Terminal Sections for Wire Cable Barrier System:

Cable barrier system is composed with wire cables, posts and terminal end.

The terminals serve in the system to hinder the uncontrolled vehicles running off the road effectively.

Types of Terminals:

Two types according to surface treatments: Hot dipped galvanized or PVC coated.

Both finishes can ensure anti-rust and anti-corrosion property, while the pvc coating can give you more option of colors.

Installing of Cable Guardrails: Both easy and flexible.

There are two ways for fixing and installing the wire cables to the terminal ends:

One is using a special engineered terminal bracket for holding three or four cables, and the bracket will be fixed to the ground firmly by anchors.

The second is to fasten the wire rope directly to the barrier post fixed with fittings.

• Business Description: SciSe is a China manufacturer and exporter of Guardrail Barrier products for expressway, bridge and highway traffic safety.
  
  Our products range from the guard rail highway barriers, sound barriers and fences to the various accessories for installation of barriers and fences.
  
  We use choic cold processing steel strip to make quality guardrail panels for our customers, going through flattening, punching, galvanizing or plastic coating, fabricating and shearing process.
  
  The guardrails can be traditional beam type solid guardrail panels or economic cable guardrails.
  
  The steel guardrail panels are made of corrugated plates in symmetrical shapes of waves.
  
  It is either concave (bowing away from the traffic lane) or convex (bowing towards the traffic lane).
  
  The guardrail beams we supply are 10 gauge and 12 gauge materials, ranging from 5 to 60 radius.
  
  Made from strip steel coils, the guardrail panels have a normal thickness of 2mm to 10mm.
  
  Metal fittings we supply include brackets, beam posts, columns and terminals for completing a full guardrail barrier system.
  
  We supply and manufacture beam guardrails in accordance with China National Standard JT/T281-1995(Corrugated Sheet Steel Beams For Expressway Guardrail - China), AASHTO M-180(Corrugated Sheet Steel Beams For Highway Guardrail - USA), RAL-RG620 (German) or any other International Standards.
  
  The base steel we use meetsSteel Grade Q235B (equivalent to S235JR according to DIN EN 10025 and Gr.
  
  D according to ASTM A283M) or Q345 (S355JR / ASTM A529M 1994).

  Where the Guardrail Barriers are Used:
  
  Highway guardrail is commonly used as a passive barrier system for highway traffic security.
  
  The steel guard railings are installed widely along the roadway and highways, especially at curves and slopes, parking lots, road corners, dead end street and other site that may cause danger or accident to people or cars.
  
  How the Guardrail Panels Work:
  
  Guardrail panels fixed along the expressway can guide the direction of the vehicles and keep them running within the safe limit.
  
  In case any traffic accidents happen such as vehicle collision, the guardrail barrier will play an important role by decelerating the speed of the collided vehicles.
  
  Due to the designed curved shape of the guardrail panels, they will allow a slowing down of the crashed vehicle without hurting it seriously.
  
  In this way, the guard rails can reduce the danger level of the involved vehicles by keeping them safely within the road, allowing them slow down and directing them back to the right way.
  
  What are popular surface treatments for the guardrail beams:
  
  We supply three types of steel guardrail beams according to the finishes:
  
  Common galvanized steel guardrails , zinc coating quantity at about 550 gram/ m2 (40µ);
  
  Heavy hot dipped zinc plated guardrails, zinc coating quantity at about 1100 g/m2 (80µ) or 1200 g/m2 (85µ);
  
  PVC coated steel highway guardrails.
  
  Functions of the Surface Treatments to the Finished Guardrail Panels:
  
  Steel galvanized guardrail coated with zinc offers more durability and maximum strength.
  
  The zinc coating also prevents discoloration and weak points caused by rust and corrosion.
  
  The zinc or PVC coating enables the following five features for the steel guardrails:
  
  1, Anti-rusting;
  
  2, Anti-corrosion;
  
  3, Longer service life with protective coating layer;
  
  4, Ultraviolet proof;
  
  5, Anti-aging.
