32 years of historyASTM A106 carbon steel pipe is one of the most widely used seamless carbon steel pipes for high-temperature and high-pressure service. Designed for demanding industrial environments, it is commonly used in power plants, refineries, petrochemical facilities, boilers, and oil & gas transmission systems where strength, pressure resistance, and long-term reliability are critical.
Carbon steel square tubes, also known as Square Hollow Sections (SHS), are available in a wide range of sizes, wall thicknesses, and material grades for structural and mechanical applications. This guide provides a quick reference for selecting the correct carbon steel square tubing.
Selecting the right structural steel is critical for projects that demand high load capacity, long service life, and reliable mechanical performance. While both seamless and welded square tubes are widely used across industries, seamless square tubes provide superior structural integrity because they are manufactured without a longitudinal weld seam. Their continuous steel structure offers more uniform mechanical properties, improved fatigue resistance, and greater reliability under demanding operating conditions.
