Hot sale generality high alumina brick in refractory

Our Main Advantages

As for high alumina brick series products, we excel our other high alumina brick suppliers in many aspects, such as:

We enjoy the biggest production lines of high alumina brick and largest production capacity.
---More than 8000 mts high alumina brick can be supplied per month. We can help you save your time limit for a project. Besides, we provide a small number of high alumina brick used for kinds of furnace maintenance as well.
Advanced technology makes it possible for us to have very high qualified rate of high alumina brick .
---Our qualified rate of high alumina brick has so far reached over 98%, therefore, our high alumina brick enjoy excellent quality and reasonable price from the point of view.
Abundant financial resources are one of our crucial advantages.
--- Rich fund has been obtained by us through good operation over years, which are allowed us to have the ability of operating L/C clauses in the context of of the economic crisis. Thus, we are able to pay in advance in the case of receipt of a small amount of prepayment so as to smoothen high alumina brick`s production and rush on the delivery date as well as reduce our customers' financial pressures.
