Colour Coating Line Manufacturers Carbon Coils Continuous Hot-dip Galvanizing Line Wholesale - HiTo Engineering
Product Overview
1) Product overview
Product Features
- HiTo Engineering continuous hot-dip galvanizing / galvalume colour‑coating line for carbon steel coils — a turnkey production line that plates zinc or zinc‑aluminium alloys and applies organic coatings in a single continuous process.
Product Value
- Typical capacity and sizes: 60,000–300,000 MT/year; strip thickness range roughly 0.12–2.5 mm (manufacturer listings show 0.15–2.0 mm as well); strip widths 700–1,550 mm; coating weights 30–300 g/m2. Line speeds up to ~200 m/min processing (entry/exit up to 260 m/min).
Product Advantages
- Main equipment: uncoiler, welder, storage tank, degreasing/cleaning section, continuous annealing furnace, zinc pot, air knife, skin pass, tension leveler, oiler, shear, recoiler and downstream coating/curing systems.
Application Scenarios
2) Product features
- Flexible cleaning options including chemical or high-efficiency electrolytic cleaning with combined spray/immersion modes to reduce oil contamination and improve current efficiency.
- Efficient heating (non‑oxidizing + radiant tube) and rapid, uniform strip heating; protective gas cycling high‑pressure spray cooling with variable frequency control for accurate strip temperature into the zinc pot.
- Jet‑type ceramic induction heating zinc pot and wet‑nose/recirculating zinc pump for uniform bath composition and superior surface quality.
- Real‑time coating thickness measurement and precision air‑knife control; fingerprint‑resistant / fast‑switching coating heads for organic and composite coatings.
- Advanced control architecture: vector frequency drives, CPC/EPC correction, fieldbus control and English HMI; modular customization available.
3) Product value
- Produces high‑quality, consistent coated coils suitable for demanding end‑uses (e.g., home appliances), improving finished product appearance and mechanical properties.
- High throughput and flexible specification ranges enable customers to meet diverse production goals and market demands.
- Energy and cost savings through flue‑gas waste heat recovery (used to heat cleaning liquids or generate steam) and efficient heating/cooling systems — lowers operating costs and environmental footprint.
- Turnkey, customizable solutions with technical support reduce integration risk and shorten time to production.
4) Product advantages
- Robust, low‑maintenance design with proven components for long service life (e.g., ceramic induction zinc pot, special refractory materials).
- Superior coating accuracy and surface quality due to precise temperature control, air‑knife guidance and on‑line thickness monitoring.
- Reduced defects and improved mechanical/coating properties through straightening and finishing sections.
- Competitive pricing while providing world‑class technology and ongoing specialist support.
- Flexible configuration choices and English‑language software/HMI for international customers; electrical load typically in the 2,500–4,500 kW range.
5) Application scenarios
- Production of galvanized and galvalume coils for building and construction (roofing, cladding), metal sheeting and panels.
- Home appliance panels and components requiring high surface finish and coating accuracy.
- Automotive supplier coils for non-structural panels and components.
- Coil processors, coil-coating plants and metal fabrication shops that need pre-coated steel substrates.
- General galvanizing/coil coating plants scaling from medium to large annual capacities (60k–300k MT).
