The end plate for square concrete piles generally adopts Q235B by lathe machining to ensure welding quality of connecting two piles together, of course, it's totally ok to use high strength steels like Q345B.
Both the function of steel end plate for square piles and concrete piles are same, it is mainly used for connecting piles and fasten PC wire cage, but they are different in appearance. we choose the best material for steel end plate for square piles, there are many specifications such as 250mm, 300mm, 350mm, 400mm, 450mm, 500mm, 550mm, 600mm, 650mm, 700mm as per different side length.
The dimensional variation of end plate for square piles and concrete piles are almost same, the end plate is mostly purchased outside then processed by lathe machining, and the thickness of steel plate in china market is almost no positive error, it's impossible to produce steel plate without negative error, it loses too much to adopt thicker steel plate. In addition, the end plate for square piles almost adopts steel plate by hot rolling through the technologies such as bend, welding, it's easy to control the thickness of end plate.
