Square steel pipe prices are determined by multiple factors, including material type (carbon steel, stainless steel), dimensions (side length, wall thickness), surface treatment, and order volume. Carbon steel pipes are the most cost effective, ranging from \(500–\)1,200 per ton for standard sizes (e.g., 50x50x3mm), while stainless steel (304 grade) commands \(2,500–\)4,000 per ton due to higher raw material costs. Galvanized finishes add \(80–\)150 per ton to base prices, depending on coating thickness and process (hot dip vs. electro galvanized). Smaller diameters and thinner walls (e.g., 20x20x1.5mm) are priced per meter (\(2–\)5), appealing to residential and DIY projects, while industrial grade pipes (300x300x10mm+) are sold by weight, with discounts for orders exceeding 50 tons. Regional price variations reflect local steel production costs, transportation fees, and import duties—for example, prices in the Middle East are influenced by proximity to Chinese suppliers, while North American prices include NAFTA compliance costs. Suppliers often provide customized quotes based on project specifications, including additional services like pre cutting, edge deburring, or packaging for overseas shipment, ensuring transparency in cost structures for clients.
