Description
Guardrail Block refers to Prevention block,blocker,block-out. in some places,it was named “SPACER” or “Separator”. It refers to the part between guardrail and post,and with many different shapes or designs.
Guardrail Spacer are considered as passive protectors with a view to ensure the safety of the pedestrians by the wayside and the vehicles. Highway 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.
It is mainly installed between guardrail and post to reduce the crash collision of highway/expressway/roadway. Bock itself is an energy absorbing part, so it could make theguardrail deform gradually during the sudden collisions. thus is conducive to energy absorption, reduce occupant casualties; at the same time, the block could allocate the crash energy to guardrail and post, thereby increase the overall strength and tension of the guardrail system.
The guardrail block is installed between the guardrail and the post with the function of energy absorbing. If there is no block, it has to force the vehicles to stop through the deformation of the guardrail, the post and the roadbed.

Key features
- Box, H, U, C, F and trapezoidal sections plus offset blocks
- Holds the beam at the offset it was crash-tested at
- Hot-dip galvanized to AASHTO M180 with the matching beam
- Punched to the same bolt pattern as the beam it pairs with
- Supplied loose or pre-assembled with bolts and washers
Where it is used
- Beam-and-post barrier runs
- Bridge decks and narrow offsets
- Median and shoulder installations
- Alignment offsets at transitions
- Guardrail repair and replacement
- Curved and sloped sections
