When selecting carbon steel pipe or tubing for your project, one of the most essential and impactful choices you'll face is this: Should you use a carbon steel ERW pipe or a carbon steel seamless steel pipe? This decision directly influences your project's budget, functionality, and service life.

For engineers, buyers, and importers,a clear understanding of carbon steel square tube weight and the method of calculating square hollow section weight is critical.It ia important for them to plan costs,determine design loads, and eatimate shipment tonnage.So this acticle is show how to calculate carbon steel pipe weight.

Due to Q355B outstanding mechanical properties, excellent weldability, and cost-effectiveness, Q355B has become widely used in construction, bridge engineering, car manufacturing, and several structural applications. With the continued upgrading of China’s manufacturing enterprise and infrastructure development, Q355B has grow to be a best alternative for traditional grades such as Q235 and Q345.

Global crude steel production for the 70 reporting countries reached 141.8 million tonnes in September 2025, representing a yearonyear decline of 1.6%.

Drawing on extensive technological expertise, Tianjin Yuantai Derun Group has perfected sophisticated cold forming processes, allowing for the bespoke fabrication of uniquely shaped structural steel tubing. Whether square, rectangular, oval, or intricate polygonal forms, Yuantai Derun can adjust tube measurements, wall density, and structural characteristics to suit a wide array of engineering requirements. This adaptable customization capacity represents a significant advancement in the company

In steel terminology, ”gauge ”is commonly used for sheet metal to describe the thickness or thickness range of material.

Understanding the limitations of zinc coating and surface treatment for steel products protection.

square and rectangular tubes are versatile, used in building steel structures, machinery, bridge supports, transit, greenhouses, auto manufacturing, and custom equipment frames, meeting diverse needs.

Strength refers to a welded square tube's ability to resist damage (plastic deformation or breakage) under static load, including stretching, tightening, winding, shearing, and other forms of stress.

Square tubes can be welded using a variety of methods: manual metal arc welding, gas shielded welding, submerged arc welding, argon tungsten arc welding, and plasma arc welding.
