Elevate construction standards with 7 cm concrete blocks conforming to Thai Industrial Standard 57-2533.
For engineers and project owners who prioritize "strength" and "standards," our 7 cm diameter, TIS (Thai Industrial Standard) certified concrete blocks are the ideal choice.
The products are manufactured under quality control in accordance with industrial product standards.TIS 58-2560Every step, from selecting raw materials like stone, sand, and cement, to the molding and curing processes of the concrete, results in concrete blocks with superior properties compared to ordinary bricks on the market.
Superior Advantages (Why Choose TIS Standard?):
- High Compressive Strength (Capable of withstanding actual compressive force): Having passed the compression strength tests according to the criteria set by engineers, you can be confident in the structural strength of the wall.
- Certified Quality (with certificate): We can issue test reports and product standard certification documents for use in submitting installment payments for government projects or large-scale projects.
- Durability: Dense concrete with fewer pores helps reduce water absorption, preventing moisture problems and wall cracking in the long term.
Applications
- Government jobs: Schools, hospitals, and government offices (that meet Thai Industrial Standards (TIS) requirements).
- High-rise buildings: Condominiums, hotels (used for partition walls or fire escape walls as per building control regulations)
- Factory wall construction: Requiring extra strength to prevent accidents.
(Note: For temporary fencing or applications that don't require high load bearing capacity, you can choose to use...) 7 cm standard concrete blocks. (To save money)
