What Our Customers Say

“CC always considers the details that I haven't even thought of. My villa truly benefited from her attention to every detail, and I really admire her for that. She is a strong and optimistic professional woman. After visiting your factory and becoming good friends, everything has been excellent.”

Jofra Archer

Four-floor private villa

“Actually, I visited several door and window factories in Foshan,  and ultimately decided to collaborate with JL Aluminum for two main reasons: First, CC, the owner, made me feel that she is trustworthy, sincere, and approachable, which gave me a sense of security and confidence. Second, JL's factory is truly strong, including aluminum profile raw materials, color customization, and finished doors and windows. The pricing is indeed factory direct.
