With years of experience in the design and manufacture of hollow steel balls, Dongyuan has been considered as one of the most manufacturers and suppliers. The hollow steel balls series has many styles to meet the diversified needs of customers. The encapsulation materials of DONGYUAN 6MM to 300MM metal hollow balls are purchased by our procurement team who often interviews or visits suppliers, strictly verifying the performance of the semiconductor materials. For solid brass balls, minimum order quantity will be 50kg. The product is not prone to fracturing caused by expansion. The materials used in it feature low water absorption, which prevents water or moisture from entering into the materials. Stainless steel 304 and 316 are specially adopted for making our high quality range of stainless steel artworks.
We take honesty honor as the most important developing concept. We will always stick to the service promise and focus on improving our credibility in business practices, such as abiding by contracts.
