The main specifications of corrugated guardrails include two-wave and three-wave guardrails. Specific models and specifications are as follows:
Two-wave Guardrails
Standard Specifications: Panel length 4320mm, wave width 310mm (some descriptions state that the two wave widths are specific values, but the overall width conforms to this range). Panel thickness varies from 2.5mm to 4.15mm depending on the model.
Installation Features: Net length after installation is 4 meters, with a 32cm overlap.
Common Models:
GR-C-4E: Panel thickness 2.5mm, post thickness 114mm.
GR-B-4E: Panel thickness 3.0mm, post thickness 114mm.
Gr-A-4E (Two-wave): Panel thickness 4.0mm, post thickness 140mm.
Gr-A-2E: Similar to Gr-A-4E, but post spacing is 2 meters.
Gr-Am-4E: Used for median strips.
Gr-Am-2E: For median strips, post spacing 2 meters.
GR-A-1E: Roadside guardrail, 1-meter spacing.
Three-Wave Beam Guardrails
Standard Specifications: Plate length 4320mm, wave width 506mm (including three waves), plate thickness typically 3.0mm or 4.0mm.
Installation Features: Similar to two-wave guardrails, the net length after installation is 4 meters, with a 32cm overlap.
Common Models:
Gr-A-4E (Three-Wave): Plate thickness 3.0mm, post 140mm.
Gr-SB-2C: Three-wave square post, pre-embedded installation, shorter post.
Gr-SB-2E: Three-wave standard square post.
Gr-SB-1B1: Three-wave flange post, 1-meter spacing.
GR-SA-3E: Three-wave square post, 3.32 meters long, 4.0 mm thick, driven-in post.
Explanation of Corrugated Beam Guardrail Models
GR: Abbreviation for Corrugated Beam Guardrail.
X: Represents the protection level, determining the thickness of the guardrail panel and post. Common types include A, B, C, SB (three-wave square post), SA (three-wave square post), AM (median strip), etc.
4: Post spacing, indicated by numbers such as 1, 2, 3, 4, etc., with specific values depending on the model.
Y: Indicates whether it is driven-in, pre-embedded, or flange-installed. Types include E (driven-in), C (concrete pre-embedded), B (flange), etc.
