Steel Culverts
Durable, lightweight and proven culvert solutions for New Zealand & Australia
SwiftSteel™ steel culverts are designed for demanding civil, rural and infrastructure projects across New Zealand and Australia. Combining high strength-to-weight performance with rapid installation and long service life, they provide a cost-effective solution for drainage, stormwater, road, and rail projects where reliability and compliance are critical.
Why Choose Corrugated Steel Culverts?
Corrugated steel culverts have been trusted worldwide for decades as a versatile alternative to concrete. Their corrugated profile provides outstanding structural strength while remaining lighter and easier to transport and install. Unlike rigid concrete, steel culverts flex with ground movement, reducing the risk of cracking and costly repairs.
SwiftSteel™ advantages include:
Strong, lightweight and easy to handle on-site
Faster installation with less heavy machinery required
Compliant with AS/NZS 2041.1:2011
Long design life with protective coatings
Flexible performance under traffic, vibration and soil load
Proven compliance with AS/NZS standards
