| Annular Corrugated Steel Pipe | Corrugations run around the circumference of factory-made pipe sections. Sections are usually joined with sleeve or band couplers. | Approx. 300–3,600 mm diameter Short and medium lengths | Commonly galvanized steel with nominal thicknesses around 1.6–4.3 mm, depending on diameter, loading and local specifications. | Road and railway culverts, stormwater crossings, drainage channels, agricultural waterways and temporary access crossings. | Fast installation, simple handling, widely available fittings and good suitability for standard culvert projects. | Performance depends on soil support, cover depth, bedding quality, hydraulic capacity and corrosion conditions. Larger spans may require structural analysis. | ASTM A760/A760M, ASTM A929/A929M, AASHTO M36/M36M and applicable national structural design codes. |
| Helically Corrugated Steel Pipe | Steel strip is formed into a continuous helical pipe with a spiral seam. The helical seam may be lock-seamed or welded, depending on the product design. | Approx. 300–3,000 mm diameter Long continuous lengths available | Commonly produced in galvanized or metallic-coated steel, often approximately 1.6–3.5 mm thick for standard drainage sizes. | Storm sewers, highway drainage, utility crossings, agricultural drainage and culverts where long pipe sections are useful. | Efficient production, reduced number of circumferential joints, relatively low transport weight and flexible length options. | Seam type, joint watertightness, coating condition and installation backfill are important. It is not automatically suitable for high-pressure or fully pressurized service. | ASTM A760/A760M, ASTM A929/A929M, AASHTO M36/M36M and project-specific hydraulic requirements. |
| Structural-Plate Corrugated Steel Pipe | Large individual corrugated steel plates are assembled on site with bolted longitudinal and circumferential seams to form a circular pipe. | Usually above 3,000 mm span Large custom spans possible | Typical plate thickness is approximately 4.3–8.0 mm, subject to span, cover, soil properties, live load and design code. | Large highway culverts, railway underpasses, flood channels, wildlife passages and high-capacity drainage crossings. | Suitable for large openings, easier transport than fully assembled large pipes and adaptable to difficult access conditions. | Requires engineered soil-structure interaction, controlled backfilling, bolt inspection and careful foundation preparation. Installation quality strongly affects performance. | AASHTO LRFD Bridge Design Specifications, AASHTO M167/M167M, ASTM A761/A761M and relevant national steel structures codes. |
| Corrugated Steel Pipe Arch | Factory-made or assembled corrugated sections with a curved crown and relatively flat invert. The shape provides a wider opening at a lower vertical height. | Common spans about 1,200–6,000 mm Height depends on the selected rise | Typical steel thickness ranges from approximately 2.0–6.0 mm for many applications; structural designs may require thicker plates. | Sites with limited vertical clearance, stream crossings, roadway widening projects, pedestrian passages and wildlife crossings. | Provides a broad waterway or passage while reducing required vertical clearance compared with a circular pipe. | Requires a stable, well-prepared invert or foundation. Hydraulic behavior, side support and clearance around the arch must be checked during design. | AASHTO M36/M36M, ASTM A760/A760M and project-specific structural design standards. |
| Corrugated Steel Box or Multi-Plate Underpass | Multiple corrugated plates are bolted into a box, low-profile arch or custom underpass shape. The system is assembled at the project site. | Approximately 3–12 m span for many projects Custom geometry possible | Often uses plates approximately 4.3–8.0 mm thick, with the final thickness determined by structural calculations and loading conditions. | Pedestrian and cycling underpasses, livestock passages, wildlife crossings, utility corridors and low-clearance road crossings. | Offers large usable widths, modular transport and flexible geometry where conventional round pipe is unsuitable. | Needs geotechnical assessment, engineered foundations, controlled compaction and detailed verification of live loads, settlement and drainage. | AASHTO LRFD, ASTM A761/A761M and applicable national bridge or buried-structure design codes. |
| Perforated Corrugated Steel Drainage Pipe | Corrugated steel pipe manufactured with regular perforations or slots in the pipe wall to allow groundwater to enter the drainage system. | Commonly 100–1,500 mm diameter Perforation pattern varies by project | Often galvanized steel around 1.6–3.5 mm thick. A geotextile filter or graded drainage aggregate is normally selected with the pipe. | Subsoil drains, foundation drainage, sports-field drainage, retaining-wall drainage, road-edge drainage and agricultural water management. | Lightweight, easy to install and effective for collecting groundwater when combined with a suitable filter envelope. | Perforation size and open area must match the soil. Filter design is essential to reduce soil migration and clogging. The pipe should not be used as a pressure pipeline. | ASTM A760/A760M, ASTM A929/A929M and local drainage specifications. |
| Coated Corrugated Steel Pipe | Corrugated steel pipe with a protective metallic or polymer coating selected for the expected soil, water and atmospheric exposure. | Available in most standard profiles Diameter and length depend on the base pipe | Common options include zinc-coated steel, aluminum-coated steel and polymer-laminated or polymer-coated steel. Coating mass and thickness must be specified by the applicable standard. | Marine or coastal environments, acidic or alkaline soils, road drainage, stormwater systems and projects requiring extended service life. | Improves resistance to corrosion and abrasion compared with unprotected carbon steel, when correctly selected for the exposure. | Coating selection must consider pH, resistivity, chloride level, abrasion, flow velocity, temperature and expected service life. Damaged coating areas require approved repair procedures. | ASTM A929/A929M, ASTM A742/A742M, EN 10346 and project-specific durability requirements. |
| Corrugated Steel Pipe with Watertight Joints | Standard corrugated pipe fitted with specialized gaskets, external bands or connector systems designed to limit infiltration and exfiltration. | Commonly 300–3,000 mm diameter Joint system determines length flexibility | Usually galvanized or otherwise coated steel, with wall thickness selected according to diameter, cover, traffic loading and structural design. | Stormwater systems near groundwater, environmentally sensitive crossings, sanitary drainage interfaces and applications requiring controlled leakage. | Reduces groundwater infiltration, soil loss and exfiltration when joints are correctly aligned and sealed. | Joint performance depends on gasket compatibility, pipe alignment, surface condition, installation temperature and pressure limits. Watertightness should be verified where required. | ASTM C361/C361M where applicable, AASHTO M36/M36M and project-specific watertight joint requirements. |
