March 15, 2026 · PMX Ductwork
Need to replace a rusted-out elbow? Designing a whole new HVAC system and need custom ductwork? Ordering duct fittings used to mean phone calls, faxes, and waiting days for a quote. Not anymore. At PMX Ductwork, we've streamlined the process, allowing you to configure and order custom ductwork online with ease. This guide will walk you through everything you need to know, from understanding your ductwork needs to placing your order with confidence.
Understanding Your Ductwork Needs Before Ordering Custom Ductwork Online
Before you even think about clicking a button, take some time to assess your ductwork requirements. Accurate measurements and a clear understanding of your system are crucial for a successful order. Here's what to consider:
Material: Galvanized steel is the most common and cost-effective choice for most applications. It's durable and provides good corrosion resistance. Aluminum is lighter and offers superior corrosion resistance, making it ideal for coastal environments or applications where weight is a concern. Stainless steel is the premium option, offering the highest level of corrosion resistance for demanding environments like kitchens or laboratories.
Dimensions: Measure everything precisely! For straight duct, measure the length and diameter (for round duct) or width and height (for rectangular duct). For fittings like elbows, transitions, and reducers, you'll need to measure the dimensions of each end and the angle of the elbow or the length of the transition. Double-check your measurements – mistakes here can be costly. Don't forget to check out our selection of straight duct if that's all you need.
Gauge (Thickness): The gauge of the metal affects its strength and rigidity. Thicker gauges are generally used for larger ducts or applications where higher pressures are expected. Consult local building codes or an HVAC professional to determine the appropriate gauge for your application.
Seam Type: Longitudinal seams in ductwork can be either snap lock or welded. Snap lock is typical for smaller ducts, while welded seams offer a stronger, more airtight seal for larger ducts or higher-pressure systems.
Having this information readily available will make the custom ductwork online ordering process much smoother.

What are Common Mistakes to Avoid When Ordering Ductwork Online?
Ordering custom ductwork online offers convenience, but it's crucial to avoid common pitfalls that can lead to delays and incorrect orders. Here are some key mistakes to watch out for:
Inaccurate Measurements: This is the most common mistake. Double and triple-check all your measurements before placing your order. Small errors can result in fittings that don't fit properly.
Incorrect Material Selection: Choosing the wrong material can lead to premature corrosion or structural failure. Consider the environment and application when selecting galvanized steel, aluminum, or stainless steel.
Ignoring Gauge Requirements: Using a gauge that's too thin can result in ductwork that's prone to denting or collapsing. Consult local codes or an HVAC professional to determine the appropriate gauge.
Forgetting Sealing Requirements: Ensure that your fittings are properly sealed to prevent air leaks. This is especially important for high-pressure systems. Consider using mastic or foil tape to seal joints.
Not Considering Accessibility: Think about how you'll install the ductwork before ordering. Ensure that you have enough clearance to maneuver the fittings into place.
Neglecting Local Codes: Always comply with local building codes and regulations. These codes may specify requirements for materials, gauge, and installation practices.
By avoiding these mistakes, you can ensure a smooth and successful custom ductwork online ordering experience.
