Square hollow section steel market Size
The global square hollow section steel market size was estimated at USD 24 billion in 2025 and is projected to reach USD 44.7 billion by 2035, growing at a CAGR of 5.80% from 2026 to 2035.
The square hollow section comes in various sizes, wall thicknesses, and specifications. Square hollow sections or square tubes are made of either hot rolled, cold rolled, pre-galvanized or stainless steel to form cold and welded. The suitable mother tube, a round steel tube, has to be formed first to form the square steel section. Using rolls from a round tube, this gradually presses the round tube into a square hollow section. All of that is done inline. The advantage of square and rectangular steel tubes is that they are stronger in bending while a round hollow section has more twisting stiffness. Many projects benefit from square steel tubing, including all building types, highway guardrails and signage, column support, trusses, bridges, heavy equipment, storage systems, and exercise equipment. When combined with the appropriate steel grade, a wide range of dimensions ensure that the structure's functionality and cost-efficiency can be optimized.
Market Highlights
Growing residential and non-residential construction activities and development demand for steel products as building materials will promote growth for the hollow structural sector industry. Additionally, advanced building technologies like 3D printing and business information modeling are gaining rapid popularity in the engineering and construction sectors. This development is also expected to have a positive impact on demand for hollow section steel in industrial buildings in the years ahead. . Its uniformity makes it visually appealing and predictable to use. It has an elevated ratio of weight to strength. Bending is easy, and because square steel tubing is cheap, it is cost-effective, even for large projects. Stainless steel tube is easy to recycle. Many projects benefit from square steel tubing, including all building types, highway guardrails and signage, column support, trusses, bridges, heavy equipment, storage systems, and exercise equipment.
