Product Overview
1) Product overview
Product Features
- HiTo Coils Colour Coating Line (colour coating machine) is a turnkey coil processing line for producing pre-painted and coated steel coil products. It supports cold-rolled low‑carbon steel substrates (typical thickness range ~0.12–2.5 mm, model specs 0.15–2.0 mm) and strip widths ~700–1550 mm. The line can be supplied as complete sets (manufacturer lists production capacity ~10 sets) and is designed for medium-to-high annual throughput (60,000–300,000 MT/year).

Product Advantages
- Complete process equipment: uncoiler, welder, storage tank, degreasing/cleaning (chemical and high-efficiency electrolytic options), continuous annealing furnace, protective-gas/jet cooling, zinc/aluminum pot (hot-dip galvanizing/galvalume), air knife, skin pass, tension leveler, oiler, shear, recoiler, straightening and finishing sections.
Application Scenarios
- Advanced heating and pot technology: combined non-oxidizing (NOF) and radiant tube heating, jet-type ceramic induction heating zinc pot, furnace nose wet nitrogen and circulating zinc pump.
- Real-time process control and measurement: coating-thickness online gauges, vector frequency drives, CPC/EPC correction, field-bus control, user-friendly HMI (English).
- Energy and quality optimizations: waste-gas heat recovery, high-pressure spray cooling with variable frequency control, fingerprint-resistant coating module with fast switching.
- Configurability: optional cleaning modes, customizable equipment configurations and software/HMI in English.
3) Product value
- Produces consistent, high-quality coated coils with precise coating weights (coating types GI/GA/GF; coating weight range ~30–300 g/m²) and improved surface/shape quality for demanding end uses (e.g., home appliances).
- Reduces operating costs through energy recovery, efficient heating and process automation.
- Shorter time-to-market and lower CAPEX impact due to integrated, configurable line layout (compact modules such as fast-switch coating units).
- Ongoing specialist support from manufacturer and ability to tailor solutions to customer production goals and budgets.
4) Product advantages
- High technical maturity and R&D backing (HiTo engineering) combined with competitive pricing and global support.
- Robust process control and measurement for accurate, repeatable coatings and minimal scrap.
- Energy-efficient design (waste heat recovery, efficient heating systems) and high-speed production capability (entry/exit up to ~260 m/min, processing up to ~200 m/min).
- Enhanced strip surface quality from advanced cleaning (electrolytic cleaning option) and finishing/straightening equipment.
- Durable, low-maintenance components (ceramic induction heating pot, improved insulation materials) and safety-minded designs to reduce secondary contamination.
5) Application scenarios
- Manufacturers of pre-painted/coated steel coils for roofing, cladding, facades and building materials.
- Appliance and white‑goods manufacturers requiring high-quality coated substrates.
- Producers of sandwich panels, metal doors, HVAC components, furniture and other fabricated metal products.
- Galvanizing and galvalume service lines and cold‑rolled steel processors converting coils to ready-to-use painted or galvanized coils for downstream fabrication.
