WHAT IS SEJIN
GRP WATER TANK?
∙ SEJIN GRP panels, which constitute the main body of this water tank, are manufactured using
SMC (Sheet Molding Compound: the mixture of unsaturated polyester resin, glass fiber, filler,
CHARACTERISTICS

GRP WATER TANK
mould release agent and catalyzer) by hot press moulding process. They are assembled at the field
using steel stiffeners and bolts so that the size and capacity can be designed without limitation.
∙ The foam sealant at the joint part of the panels provides perfect watertight performance to this
bolting type water tanks; all the components, including GRP panels, which constitute the tank have
sanitary and durable properties to meet the Food Sanitation Act. SEJIN GRP Sectional Tanks are
suitable for the storage of drinking water.
1. Sanitation
∙ Nontoxic, WRAS certified materials
∙ Complete blocking of sunlight transmission prevents the formation and growth of
bacteria and germs.
∙ Smooth surface finish minimizes moss and scale.
2. Excellent durability
∙ SEJIN GRP Water Tanks are designed by FEM (Finite Element Method) analysis
and obtained PSB certificate.
∙ The internal tie-rods in stainless steel are coated with PE by heat-shrink tubing
process, which provides stronger corrosion resistance.
∙ The external components are hot dip galvanized steel, which gives semipermanent life
3. Absolute water tightness
∙ The foam type gasket with excellent elasticity and resilience assures perfect
water tightness.
4. Versatile capacity design
∙ Various panels make installation of tanks possible in any dimensions or
capacities. (L-shape, U-shape, square-shape)
5. Easy installation
∙ The installation of tank is very user-friendly even in the restricted area by using
standardized bolting type panels.
6. Outstanding insulation performance
∙ Pre-insulated panels are also available as an option. By using the PU foam
insulated panels, the temperature change of the water in the tank can be
minimized at high or low environmental temperature.

Reinforcing System
No Internal Reinforcement System
Reinforcing
System
Tanks up to 2m height have no internal tie-rods and
are reinforced externally with hot dip galvanized steel.
This system allows easy access into the tank during routine
cleaning.
Remark : No internal reinforcement system is available over 2m
height by the customers request.
No Internal Reinforcement System
Inside Reinforcing System
Tie-rods are installed inside of the tank to improve the strength
and stability of the tank structure.
Corrosion-proof PE heat treated stainless steel tie-rods and
GRP tie-rods are applied.
Remark : Various grades of stainless steel tie-rods without
coating are available by the customers request.
Inside Reinforcing System
Inside & Outside Reinforcing System
Internally and externally reinforced system is applied
for 5m or higher tanks for the cases when the tank's height
has to be increased to meet the capacity requirement due to
narrow installation space.

Pre-insulated Panels
High Strength SMC
SEJIN GRP panels pre-insulated with polyurethane foam provide outstanding thermal performance.
The pre-insulated panels are recommended in such cases when tanks are installed under high/low
environmental temperature or high humidity as the insulated panels keep the water within the tanks at an
As the glass fiber, one of the main ingredients, is increased in the SMC, the strength and hardness of panels
is increased, the safety of large water tanks is improved, and surface contamination with scratches is
prevented.

· Disinfection of harmful microorganisms, suppression of microbial
growth, and deodorization (harmful microorganisms: bacillus,
staphylococcus aureus, mold, P. aeruginosa, and bacillus subtilis)
· Uniform antimicrobial performance in the tank for semi-permanent
antimicrobial effect
· Differentiated molding method for the maximum antimicrobial effect
