Corrugated galvanised steel culverts have been used around the world for well over 100 years and are a proven option for typical civil infrastructure applications. Steel Multi-plate is a cost-efficient culvert offering up to 50-year design life in low corrosion environments in New Zealand.
For more information on the durability, performance and methods for predicting the service life of CSP's range of Multi-plate structures click here.
For more demanding applications CSP also offers products with extended service life - Aluminium Multi-plate (75 years) and Multi-plate 100+ (100 years). Steel Multi-plate culverts can span up to 8m (depending on the loading and backfill). For spans exceeding 8m refer to CSP's SuperCor™ information.
The versatility of Multi-plate structures is limited only by engineering inventiveness. Traditional uses include culverts - small and large, bridges, storm drains, pedestrian and stock underpasses. However, other applications include mine and tunnel portal protection, conveyor housings, water tanks, caissons, underground storage facilities, and even wineries.
