I'm interested in obtaining detailed pricing information for steel posts that are suitable for wood fences. Could you provide me with your current rates, including any bulk order discounts? Additionally, please share specifics regarding the dimensions, weight options, and available finishing types for these posts. Knowing the lead times for delivery and any potential shipping costs would also be helpful. Looking forward to your prompt response!
