Unlike traditional carbon steel tubes with circular or square cross-sections, Hexagonal Shape Carbon Steel Tube features a six-sided profile capable of uniformly distributing external forces; they demonstrate superior performance compared to square tubing, particularly when subjected to torsional (twisting) loads.

Manufactured using a precision cold-forming process, these tubes feature a tolerance of ≤ ±0.05 mm across opposing hexagonal flats and a wall thickness tolerance of ≤ ±0.05 mm. Free from defects such as ovality, deformation, or burrs, they can be directly butt-joined during installation without the need for secondary processing.

Customized Services

TORICH offers a comprehensive range of customization services to meet diverse engineering and structural requirements:

We support the customization of hexagonal dimensions, material grades (e.g., 10#, 20#, 45#, Q195, Q215, Q235, Q345), and other specifications.
We can perform various punching, drilling, or laser-cutting operations for holes of specific diameters and shapes, strictly in accordance with the provided technical drawings.
We offer a variety of surface treatments, including hot-dip galvanizing, anti-corrosion coatings (such as epoxy, coal tar pitch, or PVC coatings), and rust-preventive oil application.
We provide various tube-end finishing services, including plain-end cutting, chamfering, flaring, swaging, and flattening.

Possible Alternative Grades

ASTM A36 Steel: A low-cost option suitable for general structural applications; compared to A500 Grade B/C, it is more readily available but offers lower strength.
EN 10219 S355JR: The corresponding grade under European standards, featuring a higher yield strength (approximately 355 MPa) and suitable for heavy-duty structural frameworks.
JIS G3466 STKR400: Widely utilized in Asian markets, suitable for light-to-medium structural applications, and characterized by excellent weldability.
ASTM A513 Mechanical Tubing: Offers superior dimensional precision, making it highly suitable for manufacturing mechanical components and precision parts; it is not intended for heavy-duty structural applications.
