How to Measure

To ensure you order the correct square tubing from Bobco Metals in Los Angeles, measure the outside dimensions of the tube. Square tubing is specified by the length of one outside wall. For example, a 2-inch square tube measures 2 inches from the outside of one wall to the outside of the opposite wall. Also determine the wall thickness, which is critical for strength. Use calipers for accuracy. For length, measure the total end-to-end distance needed for your application, accounting for any overlap in joints. When planning, remember that our cutting service can help minimize waste. Always confirm material type (steel, galvanized, aluminum) and finish requirements. Our team is always available to assist with measurement and specification questions.
