Heavy-Duty Coating for Large Steel Components
Steel Structure Powder Coating Lines
Heavy Load Capacity & Large Part Handling
Ketao designs powder coating lines for steel structures including I-beams, H-beams, columns, trusses and heavy steel fabrications.
Our systems handle large dimensions (up to 12m length), heavy loads (1000+ kg per hanger) and meet C4-C5 corrosion resistance for outdoor structural applications.
- 1000+ kg load capacity
- Up to 12m length handling
- C4-C5 corrosion resistance
- Zinc-rich primer compatible
Key Challenges in Steel Structure Coating
Heavy Load Handling
Steel beams and columns can weigh 500-2000 kg. Requires reinforced overhead conveyor with I-beam structure and heavy-duty drive motors.
Large Dimensions
Beams up to 12m long require extended spray tunnels, long ovens and special hanging systems to prevent sagging during heating.
High Corrosion Resistance
Outdoor structures need C4-C5 (720-1000+ hours salt spray). Requires zinc phosphate pretreatment and thick powder film (80-120 µm).
