Product Description
Splice bolt: Splice bolts are mainly used to splice two sections of guardrails together to extend the length of the guardrail. Splice bolts can be quickly disassembled, making maintenance and replacement more convenient. Usually, splice bolts are suitable for corrugated guardrails that are in the same plane as the road surface, such as highways, municipal engineering, landscape engineering, etc.

Connecting bolt: The connecting bolts are mainly used to connect the guardrail into a whole section structure, so that it has the ability to resist external forces as a whole. Connecting bolts are generally used for guardrails with arched foundations, which can maintain the integrity of the original structure after being impacted and protect road safety.
