Our encapsulated pretreatment rooms use multi-wall leak-proof panels, heavy-duty steel structures, and acid-proof cladding (PVC/FRP) to isolate fumes from the shop. Negative-pressure ventilation with slot-hoods over each tank ensures full capture before escape. LED lighting, toughened-glass windows, auto sliding doors, insulated paneling, and service platforms deliver a clean, low-corrosion environment that protects cranes, structures, and electrics—paying back quickly through fewer failures.
