I'm interested in knowing if your factory produces galvanized roof metal screws, specifically with a hex washer head and colored finish. I'm looking for a type that is suitable for sheet metal applications. Could you please provide me with details on the pricing and minimum order quantities for these screws? Additionally, any information on available colors and lead times would be greatly appreciated. Thank you!
