China Galvanized Highway Guardrail Traffic Road Crash Barrier Beam Back Plate

Guardrail splice and post bolts:
Highway and rural road ubiquitous waveform guardrail is an important part of traffic safety facilities, small bolt in waveform guardrail played a huge role in the practical application, link fence post make a guardrail can stronger so as to play a bigger role, reduce the number of traffic accidents, reduce the loss brought by accidents and protecting people's life.
Due to the difference in material and tensile strength, the bolts of highway corrugated guardrail are divided into anti-theft bolts and ordinary bolts by type.The anti-theft bolt is divided into anagrams AB anti-theft bolt and pentagrams anti-theft bolt.The spliced bolt is round head or oval head, and the connecting bolt is hexagonal bolt.
The bolt of corrugated guardrail can be divided into Q235 ordinary material and C45 steel high-strength grade bolt according to the material, among which C45 steel high-strength grade bolt has high cost and high tensile strength, and is currently partly applied to the highway. Part of the project M16x35 splicing bolts are also required to use C45 steel high strength class.
Bolt diameter of common specification of corrugated guardrail bolt is M16, length is 180mm, 170mm, 150mm, 50mm, 45mm (also available 42mm), 35mm.The 170mm long bolt is a piercing bolt, which is used for connecting the column to the block or the column to the bracket; the 50mm and 45mm long bolt is used for connecting the block to the corrugated plate or the bracket to the corrugated plate; and the 35mm long bolt is used for joining the corrugated plate to the corrugated plate.
