I am reaching out to inquire about the availability and pricing for 20,000 steel drums with a capacity of 210 liters each. It's important for us to assess the quality and specifications of the drums, so please provide details on the materials used, durability, and any certifications your products may have. Additionally, we are interested in understanding the lead time for production and delivery, as well as any bulk order discounts you might offer. If you have any brochures or product sheets available, please share those as well. Looking forward to your prompt response so we can move forward with our procurement process.
