From flue pipe coating lines to cast iron stove body enameling plants — high-temperature powder enamel (~780–850 °C fusion), wet (slip) enamel and silicone polyester powder coating, engineered for production volume.
Stoves and flue pipes expose their surfaces directly to high temperatures, which makes heat-resistant enamel — a glass layer fused to metal at approximately 780–850°C, not a paint — ideal for this application. STRONG3000 engineers the application, automation and firing technology behind electrostatic powder enamel for steel bodies and pipes, and wet (slip) enamel for cast iron stove bodies.
From individual application equipment to complete turnkey lines, we tailor the process to every stove and flue pipe part and production target.
Heat-resistant powder coating is also used on decorative, lower-temperature exterior surfaces. Below we summarize how we approach each part with the right process, the right substrate and the right firing window.
Risk of fish scale and outgassing at weld seams; decarburized steel and ~800-850°C fusion firing for a flame-side-resistant, self-cleaning powder enamel interior.

Uniform thickness on the thin-walled cylinder and coverage of the weld seam are critical; interior and exterior powder enamel on a continuous line for resistance to flue gas temperatures and acidic condensate.

Outgassing from porosity in cast iron can cause blistering; ground coat + cover coat wet (slip) enamel and controlled annealing for a decorative, non-porous body resistant to thermal cycling.

Risk of drips at bar ends and outgassing from casting porosity; food-safe wet (slip) enamel withstands open flame, thermal shock and spatula wear.

Continuous coverage of the perforated wall without clogging the holes is critical; heat-resistant powder enamel provides a self-cleaning surface against combustion above 500°C, slag and acidic condensate.

On exterior surfaces insulated from the flame, appearance and color consistency come first; heat-resistant thermoset powder for a decorative finish that withstands radiant heat and indoor use.
