Hot-dip galvanized steel guardrail is a product that uses cold-formed corrugated plate as the base material, with a hot-dip galvanized layer attached to its inner and outer surfaces to make it firmly bonded to the base and long-term stable.
The base material of hot-dip galvanized steel guardrail is carbon structural steel. Its mechanical properties and chemical composition index are not lower than the requirements of B/- grade 3 steel, so it has good mechanical properties and The impact-resistant surface zinc layer is made of zinc ingots and is hot-dip galvanized to firmly bond it with the substrate.
The zinc layer of this product is uniform, the appearance is smooth and smooth, and it has certain decorative properties. It also has the characteristics of strong adhesion, high hardness, and strong corrosion resistance.

Guardrail classification
Generally classified according to the installation location and anti-collision level.
Corrugated guardrails can be divided into roadside guardrails and central divider guardrails according to the installation location.
According to the anti-collision level, it can be divided into grade 1 and grade 1. Grade 1 guardrails are reinforced types and are suitable for use in particularly dangerous sections on both sides of the road. Grade 1 guardrails are used on highways.
According to the anti-collision level, it can generally be divided into Class 1 and Class B. Class B guardrails are reinforced types and are suitable for use on particularly dangerous sections of roadside, while Class B guardrails are used on dedicated highways.
Corrugated beam guardrail product introduction:
Commonly used roadside corrugated beam guardrails can be divided into B, B, B, and five levels according to the anti-collision level.
Plastic spraying The corrugated guardrail has better anti-corrosion performance. It is hot-dip galvanized first and then dipped in plastic to achieve double anti-corrosion effect
Color:
Galvanized silver white, sprayed green, white, Blue, gold, etc.
According to the waveform, it can be divided into double-wave waveform guardrail and three-wave waveform guardrail.
According to the surface treatment, it is divided into two types: hot-dip galvanized corrugated guardrail and galvanized spray-coated guardrail.
According to the installation location, it can be divided into roadside guardrails and central divider guardrails.
According to the anti-collision level, it can be divided into grade 1 and grade 1. Grade 1 guardrails are reinforced types and are suitable for use on particularly dangerous sections of roadside. Grade 1 guardrails are used on special highways. Commonly used roadside corrugated beam guardrails can be divided into five levels: B, B, B, and five according to the anti-collision level.
