AMACCAO pre-stressed square piles (pre-stressed reinforced concrete piles) are manufactured according to the world’s leading and advanced industrial production lines. AMACCAO brand reinforced concrete square (RC) pile is a traditional product of the Group and one of the leading products in the Northern market.
AMACCAO pre-stressed reinforced concrete square piles are a superior product that can replace reinforced concrete piles and some other types of piles, often used in high-rise buildings, bridges, wharves…
1. Advantages of AMACCAO pre-stressed square piles
* Special solution replacing bored piles to save 20% for any project.
* Bearing up to 750 tons per pile head.
* Applicable to buildings up to 28 floors, without using bored piles.
* Applicable to industrial, civil and transport works effectively.
AMACCAO has invested many “1.000-ton presses” to construct these piles and has applied very effectively to many projects in Vietnam, capable of replacing bored piles.
