The whole packing activities are all conducted indoors, in order to keep the pipe body dry and avoid the possible rust in the pipe body. Our products all have tight packing. Especially in the course of transportation, all the products are covered around tightly by the high quality PVC materials so as to protect the pipes from the harsh environment. We usually use the weatherproof canvas of quality to cover around pipes before the shipment, so as to maintain the pipe performance in the storage yard.
