Inside Our Factory

36,000 m² of moulding halls, twelve 1,200-ton presses and an in-house galvanizing line — every step of your tank happens under one roof.

See How a Tank Is Actually Made

Four minutes, no marketing: compound mixing, moulding, demoulding, galvanizing, trial assembly and container loading.

36,000m²

Two moulding halls

Panel moulding, frame fabrication and galvanizing under one roof.

12

Compression presses

1,200 t each; more than 500,000 panels per year.

280

Employees

Including 18 engineers and 6 installation crews.

Production Process

From Compound to Commissioning

SMC compound preparation

Resin, filler, glass fibre and curing agent are mixed and matured under controlled temperature — the batch recipe determines strength and water safety.

Compression moulding

Compound is charged into polished steel moulds and pressed at 1,200 t / 145 °C. Every panel is barcol-tested and thickness-scanned at nine points.

Frame galvanizing

Base rails, columns and bracing are hot-dip galvanized to 70 µm after fabrication, so cut edges are protected too.

Pre-assembly & fit check

Panels and frames are trial-assembled at the factory, joint by joint, before palletising — mistakes are cheaper to find here than on site.

Packing & shipping

Panels are packed flat in reverse assembly order, banded and container-loaded with a packing list matched to the site sequence.

Site assembly & test

Our crew assembles, hydro-tests at 1.5× design head, disinfects and hands over with as-built drawings.

Quality Control

How We Prove It Is Right

Quality is not a certificate on the wall; it is a set of measurements taken at fixed points in the process.

  • Incoming raw material tests — Resin viscosity, fibre tex and filler moisture verified per batch, with certificates retained for five years.
  • In-process panel checks — Barcol hardness, gel-coat thickness and nine-point thickness scan on every moulded panel.
  • Frame coating verification — Zinc thickness measured by magnetic gauge at six points per member; anything under 65 µm is re-dipped.
  • Factory trial assembly — A full ring of panels and frame is bolted and checked for joint alignment before packing.
  • Hydrostatic test on site — Filled to 1.5× design head, held 24 hours, all joints inspected; signed report issued.
  • Water quality clearance — Tank disinfected with 50 ppm chlorine solution, flushed, and a sample tested where required.
