Ductus understands that our clients are busy. We also understand the fear of the unknown. This is why Ductus has carefully selected all its partners from the supply chain right through to the specific consultant. Ductus has a strong history behind it. All Ductus delivery partners have decades of experience in duct-work delivery; and ALP invented the idea! The origins of light-weight ducts can trace its beginnings with ALP Italy.
