Guardrail Introduction
Roadside Barriers have been developed over the years to safely redirect vehicles that leave the roadway. Many different rigid, semi-rigid and flexible designs for roadside barriers have been evolved. The most common system consist of a steel w-beam rail supported on steel posts with end treatments and transitions of various designs using similar materials, that's our guardrail, it can be hot dip galvanized or sprayed.
Our guardrails are designed in pursuance to the principle of keeping the vehicle inside the road in a secure way and at the same time minimizing the loss of life and property in case of an accident.
Guardrail End Terminal Introduction
End Terminal is the specially designed end pieces of a road safety barrier system. The leading terminal is on the end of the road safety barrier system that faces oncoming traffic and the trailing terminal is on the other end. Guardrail end terminals are designed to provide a soft gating impact to prevent the end rail from spearing an impacting vehicle. Terminals also introduce tensile and flexural strength necessary to ensure redirection performance of the length-of-need section.
Guardrail End Terminal Type
The usual thickness of the end is minimum 3mm, and we could customize the colors for customers. The AASHTO guardrail fishtail terminal is worldwide applied. Similar guardrail ends include : buffer end, bridge flat end, etc.

Requirements for the Guardrail Surface Finish
A road safety barrier system shall have a surface finish that minimizes the friction between the system and an impacting vehicle. The surface finish shall be uniform, resistant to incidental damage and shall not be affected by detergents and similar agents that may be used to clean the external surfaces. Protrusions from the surface, which are likely to be struck by an impacting vehicle, shall not exceed 20 mm. Any protrusions shall be rounded or similarly treated, to reduce the possibility of snagging the body work of a vehicle or catching at the person or clothing of an individual. After construction, components shall not be left with splits, burrs or sharp edges after construction. Lapping of elements shall be in the direction of the potential path of an errant vehicle.
Road safety barrier system information
Where a road safety barrier system is proposed, the following shall be obtained, recorded and made available:
(a) The points where the need for a road safety barrier system begins and ends (length of need).
(b) Minimum transverse offset required from the edge of the adjacent traffic lane.
(c) Allowable dynamic deflection and working width restrictions.
(d) Interfaces with existing systems.
(e) The nature of the ground or structural support that is required.
(f) Provisions that have to be made for expansion or contraction of the foundation.
(g) Whether gating devices can be used as terminals.
(h) The nature of any road furniture or systems that have to be incorporated, such as acoustic devices, delineators, sign support systems, lighting columns and the like.
(i) Spacing and nature of provisions for access through the road safety barrier system in an emergency or for planned work that requires different traffic arrangements for short periods.
(j) Whether traffic can impact the road safety barrier system in the reverse direction.
