Customer Reviews
Yes we have received the reinforcing mesh and we are pretty happy with the quality. Many thanks! Chris

—— Chris Johnson

I have been ordering powder coated T 316 fly screen mesh from Qijie; unlike others, they never cut orders and always supply quality material to me.

—— Michael Jr. Venida

I had very bad purchasing experience with the previous supplier, for they always postpone shipment time. To my excitement, Qijie is always punctual.
