Corrugated steel culvert pipe

Corrugated steel culvert pipe structures are approved by most of American road and  railways administrations and national standards. They are manufactured in  accordance to American and Australia standard.

corrugated steel culvert pipe

1. Steel

Steel used for multi plate MP150 is produced in accordance with Chinese  standard.

Minimum yield strength 235N/mm2 and 345N/mm2

Steel standard Q235 and Q345

Also can accordance with EN10025

Steel standard S355JR, S235JR, S315MC

And can adopt the other standard steel according to customers’ demand

2.Depth of cover

The minimum allowable depth of cover is the largest of:

For roads H=B/8+0.2(m) H=B/6(m) and not less than 0.6(m)

For railways H=B/4 and not less than 0.6(m)

There is a possibility to reduce depth of cover provided that suitable  checking calculations will be made.

3.Durability

Corrosion resistance of steel is the main factor deciding about the  durability of steel structures. Long-term tests done in many countries of world  have proven that, the proper corrosion protection of the steel structure let to  prolong the life time of structures. Durability of structures built with use of  multiplate 150 designed for the zinc coatings give the so-called cathode  protection. Thanks to this they can protect the steel also in electrochemical  way achieving the multi-elemental corrosion protection system.

Attention: in strong corrosion environment, we suggest hot-dip plastic on the  galvanization, plastic thick 0.3mm, (single face dip), the durability is more  than 100 years.
