Features of Corrugated Steel Culvert
Superior Pressure Resistance
Corrugated Steel Culvert is made of Q235/SS400 high-strength steel with a corrugated structure that distributes loads evenly. Its compressive strength is approximately 15 times that of concrete pipes, supporting 1.5–60m of soil cover and heavy traffic pressure.
Long Service Life
Hot-dip galvanized coating effectively resists soil and water corrosion, providing a service life of 80–100 years under typical underground conditions.
Fast Installation
Lightweight modular design (about 1/10 the weight of concrete pipes) with bolted connections reduces construction time by approximately 50%.
Quality Control
Raw Material Inspection
Steel coils are verified for grade, chemical composition, and mechanical properties to ensure compliance with structural and environmental requirements.
Thickness & Dimensional Inspection
Steel plates are checked using high-precision gauges. Thickness is controlled at 2–8 mm with ±0.2 mm tolerance to ensure uniform structural stress distribution.
Corrugation Forming Inspection
Wave height, pitch, and spacing are measured after forming to ensure compliance with design standards and required ring stiffness for load resistance.
Galvanization Inspection
Hot-dip galvanized coating is tested for thickness and uniform adhesion, ensuring full coverage and long-term corrosion resistance in harsh soil conditions.
Hole Position & Connection Inspection
Bolt hole alignment and diameter are verified to ensure accurate assembly and prevent installation stress or misalignment.
Overall Structure Inspection
Finished sections are checked for diameter, length, and roundness to ensure proper alignment and structural continuity after installation.
Packaging Inspection
Before shipment, products are secured with steel straps and waterproof film to prevent coating damage, deformation, or surface scratches during transport.
