Multi Plate Corrugated Steel Pipe
Multi Plate Corrugated Steel Pipe is a type of big size steel pipe which consists of sheet of corrugated galvanized plate, combine with high tensile bolts correspond to the required shape and size.
All multi plate structure is protected from corrosion by hot dip galvanized process. The size of wave is 200 x 55 mm with the thickness is from 3 mm to 7 mm. Standard plate are classified into three types according to its width namely 940 mm, 1175 mm and 1410 mm and each width has 2400 mm of length. Curve plate which has the diameter and the hole in the side of multi plate types.

Multi Plate Super Span
Basically the plan and the properties of super span (Super stretch) can be seen as two retaining wall in which the top separated by an arc separator.
Multi plate super span type:
- High profile arch shape
- Pear shape
- Low profile arch shapes
Multi plate super span
Super span planning allows the practical to solve the problem of two large buildings of conventional multi plate; the levee problem loading and torque. Forming a large circle with larger radius is generally vulnerable to horizontal force on the side wall.
Therefore, the size of diameters which less than 6 meters will be a high retaining wall and weak for the current landfill. In overcoming the weaknesses of the stack, the method of super span is form into a horizontal ellipse shape on both sides of the wall with small radius, serve as a style archery side accumulation time progress, while its bow on the side wall (Retaining Wall) serve as the drag from the horizontal force caused by a heap of soil at the time of compaction with the equipment. In this configuration, the efficiency of different installation made based on with its basic form.
