We pursue the best system through strict design criteria, quality management, and reliable structural strength analysis.
The basic of structure analysis is designed by safety factors against threshold values. We know-how lies in the optimal safety factor in consideration of external force in the design that is expected base on physical properties after long-term use of SMC material.
In designing, the tanks ignores initial value(100%) of the physical properties of SMC material
and considers the safety factor to a minimum value(70%). Therefore, our water tank
guarantees long-term endurance.

Internal Reinforcement System
The excellent strength, durability and water tightness of the MULTANK are obtained
by connecting inner panels with stainless steel braces & tie-rods are installed inside
of the tank to improve the strength and stability of the tank structure. Corrosionproof
PE heat treated stainless steel tie-rods and GRP tie - rods are applied.

2. Inner stay configuration
Minimize the transformation of the side(transformation of 1% or less of the tank height), and it should be so designed as to improve the safety and life of tanks.

External Reinforcement System
MULTANK exterior reinforcement system refers to a system that has been
designed to withstand stress that occurs due to the hydraulic pressure
exerted on the outer part of the tank.
