By 
David Chen – Senior Production Engineer, 15 years in aluminium extrusion & global sourcing
If you are looking for a aluminium windows profiles factory that combines China’s supply chain efficiency with consistent quality and OEM flexibility, you need a partner who understands the US construction market. This guide gives you the exact technical specs, compliance requirements (ASTM/CE/ISO), typical MOQ, lead times, and sourcing tips so you can make an informed decision for your next project.
Common Sourcing Challenges for Window Profile Buyers
- Inconsistent alloy composition leading to weak frames or corrosion
- Long production cycles that delay your project deadlines
- Poor surface finish (oxidation, scratches) that requires rework
- Lack of OEM/ODM support for custom designs or branding
- Communication gaps – slow responses, unclear specifications
SHIJIAZHUANG TJJ TRADE CO.,LTD. addresses these pain points through more than 20 years of foundry and metalworking expertise. Although our core is ornamental iron, our sister extrusion lines for aluminium profiles are managed by the same experienced team, ensuring the same rigor in quality control and on-time delivery.

Compliance & Certifications for US Import
All profiles are produced under ISO 9001 management system. Our factory can provide:

Third-party inspections (SGS, Bureau Veritas) can be arranged at buyer’s cost.
OEM/ODM – From Your Sketch to Finished Profile
Many brand owners and wholesalers come to us with a concept or a competitor sample. Our in-house tooling team designs and manufactures extrusion dies (cost shared tooling fee from $300–$800 depending on complexity).
- Step 1: Share technical drawing or sample – we review for extrudeability.
- Step 2: 3D simulation and sample production (5–7 days).
- Step 3: Sample approval – mass production.
- Step 4: We can also pack with your brand, barcode, and instruction leaflets.
Our Factory Capability
Shijiazhuang TJJ has been a trusted metalworking factory for over 20 years. While we are best known for ornamental iron, our aluminium profile division is built on the same principles: skilled workers, rigorous quality checks, and a dedication to on-time delivery. We currently operate multiple extrusion lines and a full anodizing/painting workshop.
What Our US Buyers Say
Mark R. – Import Manager, East Coast Window Distributors
“We switched to TJJ after inconsistent deliveries from another supplier. Their aluminium window profiles arrive exactly to our spec – the tolerances are tight and the anodizing is uniform. Lead time stays around 20 days for container orders.”
Linda W. – Brand Owner, GreenBuild Solutions, Texas
“They managed the entire OEM process for my custom thermal-break profile. The die cost was fair, sample approved first time, and the final product holds up in our tests. Excellent communication despite the time difference.”
James H. – Sourcing Agent, US-Via-Asia Procurement
“I’ve visited TJJ’s factory – the new extrusion lines and clean working environment impressed me. Their price is competitive, but the real value is reliability. No last-minute excuses, no quality surprises. That’s rare in China.”
