Chau Au Nam company’s precast concrete components products

Outstanding advantages:

AMACCAO brand’s PC products of Chau Au Nam precast concrete JSC are chosen by major partners such as Samsung, Hyundai – Ghella, Lotte… because of the outstanding advantages as follows:

One is a high-quality product

The production stages are 100% controlled by a team of engineers, foreign experts, and experienced employees, manufactured according to ISO 9001. With extremely strict requirements, Chau Au Nam’s team of experts always guarantee the highest product quality.

All raw materials are 100% controlled through the LAS 1329 laboratory (licensed by BXD), reaching new quality into production. The production stages are also strictly controlled at all stages, from cleaning formwork, preparing steel cages, concrete work, tensioning, drying, dismantling and finishing products, storage, and warehousing, transport…

The second is to ensure the structure and safety of the project

Good bearing capacity of AMACCAO brand’s products. Component quality is controlled by manufacturing in the factory, limiting dimensional errors compared to machining at the construction site. The product overcomes the problem of building longevity, fire prevention, and environmental friendliness.

Third is a product that guarantees landscape and architecture

AMACCAO brand’s prestressed concrete members have the ability to exceed large spans, helping to reduce the cross-sectional height and increase the clearance height. If before, referring to concrete blocks in construction was very rough, now with Chau Au Nam company, talking about concrete in addition to ensuring bearing strength, it also meets high aesthetics, rich in style and body. friendly to people and the environment.

Fourth, it helps to shorten the construction time

Chau Au Nam products help to reduce the work of processing formwork and support trees. Components are prefabricated and can be constructed simultaneously, greatly shortening construction time and controlling weather during construction.

Meanwhile, Chau Au Nam company is a unit in Vietnam capable of manufacturing specific concrete structural products such as segment tunnel panels, and GRC fiberglass reinforced concrete meeting international standards, becoming a supplier for many foreign projects, competing with global brands, meeting the specific concrete components of key projects.

Five is to bring high economic efficiency

Chau Au Nam company’s products are competitively priced thanks to the reduction in input material costs, and cost optimization thanks to the large scale of the factory; reduce labor costs on site, and reduce quality control costs (because quality control at the factory is much better than quality control on site). This helps to shorten the construction schedule, leading to reduced management costs and quick capital recovery for investors.


As one of the number 1 concrete pile manufacturers in Vietnam, using fully automated production line with the world’s leading technology, Chau Au Nam company is not only recognized in the domestic market but also successfully conquered the international market with many export orders worth tens of millions of USD per year.

Piles export shipment to Taiwan

Currently, many foreign enterprises want to buy AMACCAO brand’s components of Chau Au Nam company to export to markets that are very difficult and highly competitive. That further affirms the quality and helps raise the level of construction material production of Vietnamese enterprises.

Chau Au Nam compay’s line produces piles with diameters from D200 – D600 with pile lengths up to 24m.

Advantages of Chau Au Nam:

1. Firstly, about product quality:

– Production according to a closed line in the factory, modern equipment to strictly control production stages, and stable quality of piles.

– 100% of input materials: Sand, stone, cement, steel….tested at LAS 1329 room (licensed by BXD), quality assurance is allowed to be put into production.

– The product surface is beautiful due to production on mold steel with small tolerances.

– Hot steam curing for high-quality products, the rapid development of concrete strength, and increased mold rotation.

2. Second, in terms of economic value:

– The factory has the capacity of mass production with large volumes to increase productivity, and reduce management costs, thereby reducing production costs.

– Ability to shorten construction time, and meet the schedule suitable for large-scale projects.

– Material cost savings:

+ Modern centrifugal technology helps to reduce the volume of concrete used compared to the production of concrete structural products that often have the same cross-section.

+ Reduce the volume of steel by 70% – 80% compared to normal concrete structures because the bearing steel uses high strength steel (with Fy = 14,000 -:- 16,000 kg/cm2), the belt steel uses cold drawn steel (Gender) tensile strength 550 – 650 N/mm2).

+ Change the length of piles arbitrarily according to the standards or the requirements of the project.

+ Convenient pile transportation, no environmental pollution.

+ Minimize concrete work at the site.

Prestressed concrete piles

When discussing Chau Au Nam company, people refer to an enterprise with silent and unremitting efforts in pioneering, creativity, and dedication.
