I'm reaching out to inquire about a variety of mesh sizes that we're looking to source for our upcoming projects. Specifically, we need options for different dimensions that fall within the following ranges: several sizes at 50 x 50, some larger pieces at 50 x 200, and additional stock in the 100 x 100 format. Could you please provide details on the availability, pricing, and lead times for these mesh configurations? Additionally, it would be great to know if you have any recommendations for materials or finishes available for these sizes. Looking forward to your prompt response so we can proceed accordingly!
