Customer Reviews
Zizi is trustworthy. During the five years of working with them, I felt their profession. Their pipe fittings are not only of good quality and cost-effective, but their service are thoughtful and attentive, eliminating the worry of our after-sales.

—— Nadim Akef-Purchase Manager

We also compared many other companies before we chose Zizi, but they can provide the best products and services in my ideal price. Our cooperation went well, and I also introduced my partners to buy their products.

—— Rabih Abi Saab-Project Manager

I must say their staffs are very responsible, especially Mr. Jerry. He always provides quotes and various documents in a short time, and he can consider many things in advance therefore helping me solve many problems.
