We are building a solar tunnel dryer. Inside the dryer, we are building two platforms. Platform is supported by GI pipes and Areca poles (Salike). On top of this, we want to place bamboo mats so that the Areca can be spread easily and there will be airflow from bottom. Attaching the picture of a similar screen curtain. that we are looking for. Please let us know where we can get these (or something similar) and what could be the price.
