I'm reaching out to get a quote for galvanized steel coils, specifically with a specified coating thickness, delivered to CIF Durban, South Africa. We're looking for your best pricing options and availability, as we're planning to place a substantial order. Please include any information regarding lead times and payment terms. Additionally, if you have options for different grades or specifications of galvanized steel coils, that would be helpful. We're interested in understanding the quality variations and any relevant certifications you might offer. Looking forward to your prompt response so we can proceed with our project planning.
