Plug-in guardrail network is a kind of highway steel guardrail, its structure is to divide the original guardrail column into two parts, the lower end of the steel pipe of the upper column is set in the upper end of the steel pipe of the lower column, and there are bolts across it, connecting the upper and lower column steel pipes together. It through the strengthening of the lower column, that is, the use of casing or other processes to prevent the deformation of the lower guardrail column, and at the same time the local weakening or total weakening of the upper column to control the deformation position of the guardrail column, so that although the force arm is reduced, the section bending modulus is also reduced, so as to ensure that the anti-collision level is not lower than the original standard design. This guardrail is easy to construct, easy to replace after a vehicle collision, and is suitable not only for dirt shoulders, retaining walls and bridges, but also for all forms of steel guardrails.
This product has beautiful and durable, no deformation, quick installation, is an ideal metal guardrail product. Scope of use: mainly used for park/zoo fences, campus/field fences, road traffic isolation, temporary isolation belts.
