Custom Ductwork Fabrication
Upload your drawings, submit your dimensions, or describe what you need — we fabricate it in galvanized steel, aluminum, or stainless steel and ship it to your door. No minimum order. Quote returned within 1 business day.
Clarify the 3D Configurator vs. Custom Quote Split:
Add a clear selector or callout near the top of this page: 'Know your standard size? Use our 3D configurator → | Need something custom? Submit the form below.'
This removes buyer confusion and routes standard orders to the configurator (higher conversion, less manual work) while keeping genuinely custom leads on the quote form.
What We Can Fabricate for You
- Custom-size rectangular trunk lines and plenum boxes in any dimension
- Non-standard round duct diameters and custom lengths
- Specialty transitions between unusual duct shapes or non-standard sizes
- Return air boxes and air handler connections built to your OEM equipment specs
- Flexible connectors in custom lengths and diameters
- Full duct system packages fabricated from PDF shop drawings or architectural plans
- Replacement components for existing systems where standard sizes no longer exist
- Stainless steel ductwork for healthcare facilities, food service, and laboratory environments
- Heavy-gauge galvanized or stainless ductwork for industrial and manufacturing applications
- Precision-tolerance ductwork for data center cooling systems
If it can be made from sheet metal and is part of an air distribution system, we can most likely fabricate it. Acceptable materials: galvanized steel, aluminum, and stainless steel.
How the Custom Quote Process Works
- Submit your specs: Fill out the form with your dimensions, material, and quantity. Upload a sketch, drawing, or photo — even a hand-written note with measurements is perfectly usable.
- We review and quote: A Duct2Go fabrication specialist reviews your request and responds with a price and lead time within 1 business day. Complex multi-piece orders may take 2 business days.
- We build it: Once you approve the quote, your order enters our production queue. Standard custom orders complete in 1–3 weeks depending on complexity and volume.
- We ship it: Your finished ductwork ships flat-packed or palletized via LTL freight with full tracking from our Chandler, AZ facility to your door.
From Hand Sketches to Shop Drawings — We Work With Any Level of Detail
Not every project starts with a complete engineering drawing. Whether you have a professional set of HVAC plans, a PDF shop drawing, equipment specifications, a hand sketch, or simply a list of dimensions, our fabrication team can help turn your requirements into a finished ductwork solution.
We regularly work with HVAC contractors, sheet metal shops, facility managers, builders, mechanical engineers, and property owners who need custom ductwork that cannot be sourced from standard catalogs. Our team reviews your drawings and specifications to identify potential fitment issues, verify dimensions, and ensure your custom ductwork is fabricated accurately before production begins.
For simple projects, a rough sketch with measurements is often enough to provide a quote. For larger commercial or industrial applications, we can fabricate directly from architectural plans, mechanical drawings, and detailed shop documents. The goal is simple: make the custom ductwork ordering process as easy and accurate as possible, regardless of where your project starts.
Frequently Asked Questions
What information do I need to submit for a custom ductwork quote?
At minimum: dimensions (width x height x length for rectangular, or diameter x length for round), material preference (galvanized, aluminum, or stainless), and quantity. A sketch, photo, or PDF drawing speeds up the process significantly and reduces back-and-forth. Even a hand-drawn diagram with measurements on paper is perfectly usable.
How long does it take to get a quote back?
We respond to all quote requests within 1 business day. Simple custom pieces are often quoted the same day. Complex multi-piece orders or fabrication from formal shop drawings may take up to 2 business days for a thorough review and accurate pricing.
Is there a minimum order for custom fabrication?
No. We fabricate single pieces as readily as large production runs. Whether you need one custom plenum or 500 identical transition fittings, the process is the same. Pricing reflects material cost, complexity, and quantity.
Can you fabricate ductwork from architectural or mechanical drawings?
Yes. We regularly produce ductwork from PDF shop drawings, AutoCAD files, and mechanical engineering plans. Upload your drawings in the form above and our team will review them, confirm the component list, and provide per-piece or system-package pricing.
What is the typical lead time for custom fabrication orders?
Custom orders ship in 1–3 weeks depending on complexity and volume. Simple single-piece items (e.g., a non-standard trunk section) are often completed in 5–7 business days. Large multi-component system packages may take 2–3 weeks. Your confirmed lead time is included in your quote so you can plan your project schedule accordingly.
