1. LIGHTWEIGHT
Steel structure facilitate easy handling with a mass approximately 1/ 10th respectively the mass of concrete structures.

2. STRENGTH

The added stiffness provided by corrugations and positive soil arching around the circumference of structures enables comparatively lightweight structures to withstand high loads. For example those generated by high fills as well as the impact and vibration of heavy mining and construction equipment, trains, trucks and aircraft under shallow fills.

3. AESTHETIC APPEAL
Corrugated Steels provide an attractive landscape feature for entry statements. Square or beveled end treatment options combined with local materials contribute to the aesthetic finish of the surrounding embankment and preservation of the local environment.

5. DURABILITY
Available in several material options, Corrugated Steel can be designed to meet your application needs.

6. EASY INSTALLATION
Detailed design drawings of color coded plate layouts facilitate fast assembly of MULTI-PLATE structures using lightweight equipment and non-skilled labor.

7. EASY TO TRANSPORT
Corrugated Steel can be transported in greater quantities per truckload than concrete structures. The strong and robust nature of Corrugated Steel eliminates concern of structural damage commonly experienced with concrete structures when transported over long distances or arduous conditions.

8. SIZE
