Q235 Guardrail Parts Highway Barrier Galvanized Offset Blocks For Guardrail System
Description:
Offset block is a kind of bearing part between guardrail beam and post. The block itself is a energy absorbing object, which is benefit to energy absorbing, but also can reduce damage and increase the overall strength of guardrail beams.
has superior performance of anti-corrosion used for square posts.
and impact resistance.
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.
Bock itself is an energy absorbing part,so it could make the guardrail 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.
It mainly connected to W Beam and C Type (or U type Post).
