ERW Piling & Pile Pipes

ests
Heat treatment,non-destructive test and hydrostatic test are not required when we are manufacturing the piling.
 Materials
The quality grades for the piling include PSL1 type and PSL2 type and the piling is generally made of Grade 1,Grade 2 and Grade 3 steel types.

 Technical specifications

The maximum outer diameter for the piling is 3048mm.The maximum wall thickness is 30mm and the maximum length for a single pipe reaches 20000mm
 Applications
The tubular steel pile pipes, the structural support piles and cast-in-situ concrete piles are the common usage of the pilings.
