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.
Galvanized hexagonal hollow offset block This kind of offset block is specifically has superior performance of anti-corrosion used for square posts.
and impact resistance.
U-section offset blocks are generally used C-section offset blocks are installed with with U-section posts or H-section posts. C-type posts, which looks beautiful.
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).
Guardrail block/spacer specification:196*178*200/400*3/4/4.5mm
Features:
- Low cost, long service life.

Applications:
Offset blocks are mainly used with guardrail beams, posts and post caps in the highways and bridges to reduce the collisions during the accident.
Hexagonal hollow offset block with green surface, Offset blocks are installed on the roadside,
which can absorb the impact power. which can support the guardrail beam.
U-section offset blocks have superior Galvanized c-section offset block can
performance of anti-corrosion and anti-aging. absorb energy when collisions occur.
