Green Color Zinc Coating Guard Rails  
 
W-Beam Guardrail Introduction    

W beam is the world's most widely specified safety barrier system. Highly effective and inexpensive, the most popular means of eliminating the threat from roadside hazards.Being a semi rigid barrier, W beam guardrail provides a desirable outcome for both designer and vehicle occupants. The ability of the barrier to absorb some of the crash energy reduces occupant risk and the deformation of the impacting vehicles. Dachu W-Beam Guardrail involves galvanized guardrail and Green color zince coating guard rails.  
 
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.
