Product Description

Kindly Note
Before placing an order, we kindly ask you to contact us. Please note that the displayed product price is solely for reference and may not reflect the actual selling price. Given the vast variety of product sizes, it's crucial to provide specific parameters for precise processing. For quartz tubes, please specify the outer diameter, thickness, length, and quantity. For square pieces, details like length, width, thickness, and quantity are needed. Providing a drawing via email will allow us to craft a precise quotation tailored to your needs.
