Buying Aluminum Window Profiles from China: A Factory Buyer’s Guide

This guide explains how MT Flying Aluminum, one of the top 5 aluminum profile manufacturers in China, handles all three from its extrusion base in Foshan, Guangdong, and also gives you a checklist you can use with any supplier.

Aluminum door profile China: matching door systems

In most cases, buyers do not order windows alone. If you also need an aluminum door profile China source, it is usually cheaper and safer to take doors from the same extruder, so colors match batch to batch and one supplier is responsible for the interfaces. Our full door range is on the aluminum door profiles page; the main systems are:

How to evaluate an aluminum window profile supplier in China

Price per kilo is easy to compare. However, the problems usually show up later on the cutting saw, at the corner joint or after the first summer. Ask every supplier for these points in writing before you place an order:

  1. Alloy and temper. Confirm 6063 and the temper (T5 or T6) on the mill certificate, not just the quotation.
  2. Wall thickness and tolerance. Agree the nominal wall (for example 1.4, 1.6 or 1.8 mm) and the minus tolerance. In short, thin walls save weight but weaken screw ports and corner cleats.
  3. Thermal break strip. Ask for the strip material (PA66 with glass fibre is the norm) and width, because it decides insulation and structural strength.
  4. Finish specification. State coating thickness, powder brand, color code and gloss for powder coating, or film thickness for anodizing. Ask for a color sample from the production line, not a printed chart.
  5. Die ownership. For custom sections, agree who owns the die and how long it is kept.
  6. Acceptance criteria. Dimensions, straightness, finish and assembly fit should be agreed before extrusion starts. We confirm these against one approved drawing for every order.
  7. Packing. Protective film, paper interleaving and bundle size should match how your team unloads. Mixed orders need clear bundle labels.
  8. System completeness. Check whether the supplier can provide hardware, gaskets, corner keys and screws that were tested with the profile.

Surface finishes

We run both horizontal and vertical powder coating lines plus anodizing and wood-grain transfer. As a result, we can match one color across windows, doors and trims in the same order, which is the most common complaint buyers have when they split orders between suppliers.

One-stop supply for fabricators

Our delivery system packs everything a window or door needs together with the profiles: hardware, seals, hinges, screws and corner pieces, in the quantities you actually use. For example, small and mid-sized fabricators tell us this lets them start production without holding a large accessory stock. You can buy:

  • Profiles only, from stock or from your own drawing (OEM)
  • Profiles plus a complete accessory kit
  • Finished aluminum windows and doors, made to size

MOQ, lead time and shipping

Stock profiles have no minimum order and can ship from 1 day. Custom colors or sections start at 300 kg and typically take 15–25 days, depending on whether a new die is needed. Export packing is planned around the section shape and your unloading method, and we prepare the documentation your project or customs broker needs.

FAQ

What does an aluminum window profile from China cost?

Price is driven mainly by the aluminum ingot price on the day, profile weight per metre, finish and thermal break. Send us the series or drawing, color and quantity and we will return an itemized quotation.

Can you make profiles from my own drawing?

Yes. Simply send a section drawing, a sample or a brief. After that, we develop the die, send trial samples for approval and finally extrude to the approved drawing.

Can I visit the factory?

Yes. Many buyers combine a visit with the Canton Fair in Guangzhou (see our Canton Fair buyer guide), about an hour away. Submit your registration details and we will send an invitation letter; ask us about the current visitor subsidy.
