Principle of the Wavy Guardrail Panel System:
1. The波形grille guard is the primary type of semi-rigid guardrail panel, consisting of a continuous layout where corrugated steel guardrail panels are joined together and supported by posts.
2. Wave-shaped guardrail panels absorb collision energy through the deformation of soil bases, posts, and crossbeams, forcing out-of-control vehicles to change direction and return to the normal travel path, preventing vehicles from crashing off the road. This helps to protect vehicles and passengers, reducing losses resulting from accidents.
3. The guardrail panels with wave-shaped beams combine both rigidity and flexibility. These wave guardrail panels have a strong capability to absorb impact energy and offer good visibility guidance. They harmonize well with the road alignment, have an attractive appearance, can be used on small-radius curves, and are easy to replace at damaged sections.

One, the total length of the guardrail panels is 4320mm (with 4 meters remaining after installation), and the distance between the posts is 4 meters.
1. The two-wave beam guardrail panels are 310mm wide, with a wave height of 85mm. The thickness options are 3mm and 4mm; the theoretical weight is 49.16kg for the 3mm thickness and 65.44kg for the 4mm thickness. A kilometer of 3mm thick panels weighs 12.3 tons, while 4mm thick panels weigh 16.388 tons.
2. The specifications for the three-wave beam guardrail panels are as follows: length 4320mm, wave width 505mm, wave height 85mm, panel thickness 4mm; theoretical weight 102kg, paired with 130*130 square tube posts.
Column: Standard Φ114mm, Φ140mm, lengths typically 1.85m, 1.95m, 2m, 2.15m, wall thickness 4.5mm.
Theoretical Weight: 12.15 kg/m for Φ114, 15.04 kg/m for Φ140mm.
Section 3: Specifications - 250 guardrail panels per kilometer.支柱spacing at 4 meters, 250 posts per kilometer, 2 ends, 250 post caps, 250 resistance blocks, 250 sets of connecting bolts, and 2000 sets of splice bolts.
