Guardrail Panel Core Information
Guardrail panels are road safety protection devices made of metal. Most commonly, they feature a corrugated structure (corrugated guardrail panels) and are fixed to pillars through splicing. Their core function is to absorb collision energy, guide traffic, and prevent vehicles from running off the road or into oncoming lanes. They are a core component of highway and municipal road safety. I. Core Categories

Carbon Steel Guardrail (Q235 low-carbon steel, hot-dip galvanized and electrostatically sprayed, cost-effective, mainstream application)
Stainless Steel Guardrail (304/316L, corrosion-resistant, suitable for coastal areas and humid, salt-fog areas)
Aluminum Alloy Guardrail (lightweight, rust-resistant, aesthetically pleasing, suitable for landscape roads and urban branch roads)
2. Structural Categories
Double-Wave Guardrail (conventional, wave height 85mm, suitable for roads with speeds ≤ 80 km/h)
Triple-Wave Guardrail (reinforced, wave height 85mm, plate width 506mm, suitable for highways with speeds ≥ 100 km/h)
Reinforced Guardrail (thickened plate or increased column density, suitable for dangerous sections such as sharp bends, steep slopes, and bridge approaches)
3. Application Scenario Classification
Road-Specific Type (Expressways, Provincial Highways, County Roads, Rural Roads)
Site Protection Type (Roads in factories, scenic areas, and industrial parks, focusing on regional isolation and light protection)
II. Core Features
1. Safety Protection
The corrugated structure disperses collision impact force, reducing damage to vehicles and personnel, and preventing rollovers or falls.
Its steering function guides vehicles back to their original lane after a collision, preventing secondary accidents.
No sharp corners and smooth edges minimize secondary damage after a collision.
2. Weather-Resistant and Practical
The surface is hot-dip galvanized (zinc layer thickness ≥ 85μm) and spray-coated for corrosion and UV resistance, with a service life of 10-15 years.
It withstands harsh outdoor environments such as high and low temperatures, rain, snow, and wind, and is resistant to deformation and fading.
The modular design allows for easy installation and rapid repairs and replacements.
3. Practical Value
Low maintenance costs; localized damage can be replaced individually without complete demolition.
Customizable specifications (plate thickness, corrugation, and length) to suit different road grades and protection requirements.
Sturdy structure, strong load-bearing capacity, and can withstand impacts from large vehicles.
