I'm looking to source silica sand for an upcoming project and would like to inquire about your offerings. Specifically, I'm interested in understanding the different grades and specifications you have available, as well as any potential applications you might recommend based on the properties of your silica sand. Pricing details and minimum order quantities would also be helpful. In addition, please let me know about your lead times for delivery and any certifications or quality standards that your silica sand meets. A product data sheet or a catalog would be great to review. I appreciate your prompt response regarding availability and the options you can provide. Thanks!
