We've been moving these 6063 aluminun profiles for years now, and the first thing people notice is how well the 6063 alloy holds up under mechanical polishing and painting—it's not just about looks, the surface really takes the finish evenly, which cuts down on rework.
The temper range from T3 to T8 gives you a lot of flexibility depending on what you're framing, and most buyers go with T5 or T6 for window frames because of that it balances strength with workability when you're punching or milling the profiles.
You can get lengths from 1 to 12 meters, but we usually see 6-meter sticks as the sweet spot for door frames—anything longer and you're paying extra for shipping, and the thickness sits between 0.8mm and 2.0mm, so for standdard 60 series windows, 1.2mm is pretty common, though I've had guys push for 1.5mm on commerical jobs.
Minimum order is 3000 kg, which sounds like a lot, but that's roughly 200-300 pieces of 6-meter profiles depending on your cross-section, and we've got both ISO and RoHS certs on file if your inspector needs them—just ask for the COA with your batch.
One thing that catches people off guard is lead time; after you pick your surface treatment—say, PVDF coating or anodizing—we usually add 20 days or so for the painting line, so plan ahead if you're on a tight schedule.
Actually, this profile isn't ideal for heavy strucutral loads like beams or columns; it's really dialed in for window and door frames where you need decent strength but mostly want a clean, polished look that doesn't corrode.
We offer T3 to T8 tempers. T5 and T6 are most common for construction profiles, giving a good balance of strength and workability for window frames. T3 is softer for more forming, while T8 is harder for higher load-bearing needs.
We can sometimes accommodate a smaller trial order, like 1000-1500 kg, for new customers testing a custom design. But the standard MOQ is 3000 kg to cover die setup and production costs.
Yes, we include ISO and RoHS compliance certificates with every shipment. Just let your sales contact know if you need specific test reports or a stamped copy for customs.
Standard lead time is around 25-30 working days after die approval and deposit. Polishing and painting add about 5-7 days, but we can rush it if needed for a small surcharge.
We bundle them with protective plastic film, interleave with paper, and secure with steel straps. For extra protection against scratches on polished surfaces, we can add foam padding at the contact points.
