Different from corrugated steel pipe, corrugated structural plates are shipped to the customers in nested plate bundles and bolt-assembled into the final shape on the job site. When the diameter or span exceeds 2000 mm, corrugated structural plates becomes a better choice, especially in international trades.
The project adopting corrugated structural plates combines the advantages of easy installation, superior strength and high durability. With increased wall thickness (10mm at most) and stiffer corrugations, the plate structure can form extra large spans and adapt to extreme fill height.
Hebei Anrun Anti-Corrosion Pipe Industry Co., Ltd. can produce corrugated steel plates with a wall thickness ranging from 3mm to 10mm, in at least four corrugation profiles: 150 mm × 50 mm, 200 mm × 55 mm, 300 mm × 110mm and 400 mm × 150mm. As indicated below, the plates can be assembled into various shapes.
Anrun company offers two ways of plate connection: overlapped and edge flange. The former is more often used while the latter has some specialties. With welded flanges on four edges, the innovative design allows the construction work to be done from one side, especially suitable for bridges, tunnel reline and vertical shaft building. The flanges can either direct to outside or inside of the structure.
For each order, we will join some pieces of corrugated steel plates into the needed shape before polymer coating to test the construction convenience.
Galvanized corrugated steel plates with flange edges
Polymer coating is the last step of production for complete corrosion resistance and avoiding damages of coating layer.
The coating option largely depends on the soil condition of the job site. At least three options are available here in Anrun company: traditional galvanized, patented polymer coating finish, and combination of the two. Since established, our company has been devoted to researching and providing anti-corrosion solutions of steel products. Now we have national patent on polymer coated corrugated structural plate pipe.
Some customers are watching the production of polymer coated corrugated steel plates. You can see one piece finished and others are waiting for coating .
