Steel Road Parapet H3

INSAMETAL handles the supply and assembly of the H2, H3 and H4b steel road parapet depending on the level of crash containment that the client chooses. These parapets are placed on both edges of the road.
The parapet is devices that pass all crash test to validate their toughness and prevent vehicles fallings or leaving the road.

 

These tests accomplish with standards road safety regulations depending on the vehicle that may compromise the parapet. They must be made with specific materials and must be assembled according to the regulation.

H3 parapets usually have three or four transverse steel tubes, or they can also carry three transverses with the same dimensions and a quarter with a larger diameter at the top of the barrier.

 

These parapets can also have metal meshes behind these tubes to protect pedestrians driving along the shoulder of the road. These parapets can be painted with any RAL colour.

They are exist three types of treatments:

Hot Galvanized according to UNE in ISO 1461:

The regulation defines the hot galvanized as the formation or zinc coating in steel. Steel is submerged in a 450º molten zinc bath that causes that zinc be stuck on steel surface.

The primary aim of this procedure consists in prevent the steel rusting and corrosion that could be caused by moisture and environment pollution.

Thermo-lacquer according to UNE in 15773:

It is a process that applies a powder covering in thin layers to metal prepared to be placed into an oven and bakes it.

The architectural quality of polyester powder allows giving the better characteristics for a clean process of powdering and provides to good tough with a better aesthetical.

Duplex System (Hot Galvanized + Thermo-lacquer according to UNE in 15773):

We apply both procedures sequentially. Hot galvanized and thermo-lacquer. It is based on apply polyester powder to galvanized surfaces when is required a better result in corrosion proofing or when seeking a better aesthetical.

The parapets components are made of hot-rolled steel sheet of S235JR, S275JR and S355JR quality according to EN 10025 and hot-dip galvanized according to EN 1461.

 

This parapet is usually put on roads or overpasses where vehicle traffic and their speed can suppose a risk of leaving the road if there is a dangerous situation on this road. Therefore, most of the parapets are curved tough tubes.

 

H3 parapets are prepared to withstand the load of vehicles that are not heavy. This parapet is prepared to avoid crash deformation because of its firm grip, durability and material used.

Acero al carbono
The anchor is composed of a plate with six shackles embedded in the board. The screws pass through the anchor plate with the post, attaching all elements to the board.

 

In addition, an anchoring edge beam reinforces the durability of the parapets posts in order to heavy collision. This makes the parapet fixed to concrete.

INSAMETAL handles acoustic and road safety using these vehicle parapets. We are suppliers of this type of element. For more information, you can contact us.
