HDG Panel Tank: common questions

What is an HDG panel tank?

An HDG panel tank is a sectional water tank assembled from hot-dip galvanised pressed steel panels. Bolted panel joints and internal reinforcement form a modular storage system for commercial and industrial water storage.

What is a hot-dip galvanised water tank?

A hot-dip galvanised water tank uses steel with a protective galvanised coating to improve corrosion resistance. WINKO's HDG construction uses hydraulically pressed mild-steel plates; the existing product specification identifies an EN ISO 1461 coating finish.

What are HDG panel tanks used for?

HDG panel tanks store water for commercial buildings, factories, institutions and fire protection systems. The required capacity, connections and final specification depend on the project drawings.

What is the difference between HDG and FRP water tanks?

HDG tanks use galvanised steel panels, while FRP tanks use fibre-reinforced plastic panels. WINKO supplies both product families; material selection depends on the storage application and project requirements.

Where are sectional water tanks commonly used?

Sectional water tanks are used in apartments, schools, commercial buildings and industrial facilities. Their modular panel construction allows the tank arrangement to follow the available site space and approved design.

Can WINKO supply HDG panel tanks in Malaysia?

Yes. WINKO, the brand of Jutarama Industries (M) Sdn Bhd in Semenyih, Selangor, supplies HDG panel tanks in Malaysia. Contact the team with your capacity, location and project requirements for technical advice and a quotation.

How are HDG panel tanks installed?

Pressed steel panels are bolted together using the specified joints, seals and reinforcement. Panel flanges, stays, roof supports, access and pipe connections must follow the final tank design and approved project drawings.

How are HDG panel tanks maintained?

Maintenance includes checking for leaks, corrosion and structural condition, together with cleaning and necessary repairs. WINKO provides maintenance, repair, cleaning, consultation and after-sales support; contact the team to assess the tank and its service needs.
