Production line and factory setup overview
Strategic hot-dip galvanising that receives fabricated steel, degreases, pickles, fluxes, dries, immerses it in molten zinc, cools, inspects and dispatches corrosion-protected components.
Recommended lowest-entry line configuration Develop only after confirmed steelwork throughput, zinc and chemical supply, environmental permit, fume/acid control, safe handling, bath-size demand, inspection standards and experienced galvanising operator support are bankable.
Production process and implementation sequence
- Resource, market and site feasibility
- Process design and EPC performance guarantees
- Civil works, utilities and long-lead equipment
- Installation, commissioning and interlock testing
- Representative production ramp-up
- Laboratory qualification and buyer acceptance
- Operator training, spares and controlled handover
Products, capacity and market fit
- This is a strategic plant, not a low-entry equipment package.
- Bankable feedstock, utility, permit, market, EPC and financing evidence is required before selection.
- Operate only with an independent laboratory, defined quality release and preventive-maintenance program.
- Hot-dip galvanised steelwork - Component dimensions/weight, coating mass/thickness, surface preparation, alloy chemistry, drainage/venting, finish standard and packing - Construction steelwork, towers, transmission structures, fencing, solar supports, road furniture, fabricators and infrastructure contractors
Core production machinery and line specifications
| Machine / stage | Function / value | Production note |
|---|---|---|
| Receiving/jigging and degreasing | Prepares steelwork | Oil and handling control |
| Pickling/rinsing/flux system | Cleans and activates steel | Acid, iron and flux quality |
| Drying and zinc kettle | Applies zinc coating | Bath temperature and chemistry |
| Cooling/passivation/finishing | Stabilises coated work | Appearance and protection |
| Inspection and waste-treatment system | Releases compliant work | Coating mass and environmental control |
Raw materials, utilities and factory requirements
- Fabricated steelwork, zinc ingots, acid, flux salts, degreasing chemicals, passivation chemicals, jigs, packaging, fume-treatment media, water-treatment chemicals and laboratory consumables
- Bankable electricity/fuel/water plans, process cooling and treatment, plant fire safety, laboratory, covered stores and qualified operation team
- Environmental permits, emissions control, waste route, maintenance workshop, critical spares and site-specific safety systems
Indicative low-entry investment and implementation plan
These planning ranges prioritize economical machinery, local labor and local civil works. Final pricing follows confirmed capacity, product specification, delivery terms and site conditions.
| Scope | Indicative range | Entry-plan note |
|---|---|---|
| Pre-treatment tanks, cranes and jigging | US$12m-40m | Workpiece size and throughput |
| Zinc kettle, furnace and fume extraction | US$20m-70m | Bath size and fuel/emissions |
| Treatment, laboratory, utilities and installation | US$12m-40m | Environmental/safety critical |
| Indicative strategic project total | US$44m-150m | Land, finance and working capital excluded |
