I'm looking for a supply of galvanized mesh for a project we're currently working on. Specifically, I need details regarding the different types available, including their specifications, dimensions, and material quality. Understanding your pricing structure and minimum order quantities would also be crucial. Additionally, I'd appreciate info on your production lead times and shipping options. If there are any certifications or quality assurance processes in place, that would be great to know as well. Please send over your catalog or any relevant documents to help us move forward. Thanks!
