Fujian manufacturers supply bridge anti-collision guardrails, stainless steel river anti-collision guardrails

.Stainless steel composite pipe bridge guardrail [Superior quality] Elevated anti-collision guardrail/elevated guardrail/stainless steel composite material, reliable quality

. This product uses galvanized steel columns, and the surface of the plated columns is electrostatically sprayed. The pipe is made of stainless steel/carbon steel composite pipe, which is made of bimetallic materials such as stainless steel () and high-quality carbon structural steel (,) through high-tech simultaneous composite welding. The product combines the excellent and beautiful appearance of stainless steel, corrosion resistance and Carbon steel has many outstanding advantages in structural strength. Compared with pure stainless steel pipes, it saves costs and increases strength. It is the best upgraded product of pure stainless steel pipe. It truly realizes the perfect combination of decoration and load.

. The selection principles of bridge anti-collision guardrails have the following requirements

.
Anti-collision performance of bridge guardrails The selected guardrail type must be effective in terms of strength It is designed to absorb the collision energy, prevent the corresponding out-of-control vehicle from crossing the bridge or entering the opposite lane, and enable it to change its driving direction correctly.

. This principle is mainly based on the highway grade and the characteristics of dangerous objects on the outside of the bridge guardrail, that is, the determination of the anti-collision level. This principle is the basic requirement that all selected guardrails should meet, so this principle cannot be used as a basis for judgment on whether it is a reasonable choice.

.
Deformation degree of guardrail after collision The maximum dynamic deformation amount of guardrail after collision should not exceed the allowable deformation distance.

. This principle mainly considers whether a certain deformation of the vehicle is allowed after a collision. For example, bridge structures are generally located very high above the ground. Excessive deformation can easily cause guardrails to bear other load types besides vehicle collision forces, making the stress more complex. Steel guardrails are generally softer than concrete guardrails. If the deformation of the two after collision is to be consistent, the steel guardrail needs greater stiffness, and the steel guardrail material is correspondingly higher.
