Cable guardrail, known as cable barrier, is the mainly type of flexible highway fences for keeping vehicles within correct way.
Three or four high tensile wire ropes are mounted on the post, which is able to absorb the maximum energy by flexing to cushion
the unavoidable impact. Comparing to other steel highway guardrail, this one is relatively cheaper and easy to install with high

Details about Cables:
The cable barriers are manufactured with 3×7 high tensile steel cables (steel wire ropes), the two most commonly used today are 18mm &19mm 3X7 steel cables. A 3x7 steel wire rope has three strands, each strand is made up of 7 identical wire ropes wound around a center. Meanwhile the wire ropes are galvanized for keeping the cable free of corrosion and rusting.

Packaging of Highway Guardrail Plate
Shanghai Metal Products are packed and labeled according to the regulations and customer's requests. Great care is taken to avoid any damage which might be caused during storage or transportation. In addition, clear labels are tagged on the outside of the packages for easy identification of the product I. D. and quality information.

Construction & Lays:
The term lay refers to the direction of the twist of the wires in a strand and to the direction that the strands are laid in the rope.
The four types of lays used in wire rope are as follows:
a) Right Hand Ordinary/Regular Lay (RHRL)
b) Left Hand Ordinary/Regular Lay (LHRL)
c) Right Hand Langs Lay (RHLL)
d) Left Hand Langs Lay (LHLL)
Main producing process: The cable barriers are manufactured with 3×7 high tensile steel cables (steel wire ropes), the two most commonly used today are 18mm &19mm 3X7 steel cables. 3x7 steel wire rope has three strands, each strand is made up of 7 identical wire ropes wound around a center. Meanwhile the wire ropes are galvanized for keeping the cable free of corrosion and rusting. When the buyers receive the cable guardrail, they just need to install it right.
