3 Product classification
3.1 Product class and code
Piles are divided into prestressed concrete piles and prestressed high-strength concrete
piles. The code of prestressed concrete pile is PC; the code of prestressed high-strength
concrete piles is PHC.
3.2 Product specifications and models
3.2.1 According to the outer diameters of piles, it is divided into 300 mm, (350 mm), 400
mm, (450 mm), 500 mm, (550 mm), 600 mm, 700 mm, 800 mm, 1 000 mm, 1 200 mm, 1
300 mm, 1 400 mm, etc.
Note. Specifications in brackets are non-preferred series, the basic dimensions are shown in
Annex A.
3.2.2 Piles are divided into type A, type AB, type B and type C according to effective
prestressed value.
3.3 Structural dimensions
