1. PRESTRESSED CONCRETE PILE

Category: Uncategorized

Description

Foundation is the main part of structure in construction work. The strong foundation relates to good quality pile. TPC prestressed concrete pile is produced under quality control and up-to-date machine. There are many types and sections of piles to be selected for using in the various condition. TPC pile is followed Thailand Industrial Standard TIS 396-2549.

To select the type, cross-sectional area and length of pile must be considered to the bending moment required. For the special case, TPC can propose the alternative design to clients.

 

CONCRETE
