Hex steel tube, also recognized as hexagonal steel tubing or hexagon bar, represents a specialized category of industrial steel products featuring a precisely formed regular hexagonal cross-section. At Huashang Steel, we manufacture premium hex steel tubes with exacting tolerances to meet the demanding requirements of modern industrial applications.
The nominal size of hex steel tubing is determined by the opposite side length (S), which serves as the critical dimension for engineering calculations and fitment specifications. Our manufacturing capabilities span multiple high-performance alloys and material grades:
Stainless Steel Hex Tubes:
304/304L Series (1.4301, 1.4306, 1.4307): Excellent corrosion resistance for general industrial use
316/316L Series (1.4401, 1.4404, 1.4435): Superior resistance to chlorides and marine environments
321/347 Series (1.4541, 1.4550): Stabilized grades for high-temperature applications
Carbon and Alloy Steel Hex Tubes:
Grade 20 Carbon Steel: Cost-effective solution for standard mechanical applications
Grade 45 Carbon Steel: Medium carbon content providing enhanced strength and hardness
16 Manganese Alloy: Improved toughness and wear resistance for demanding applications
Duplex and Super Duplex Steel:
S31803/S32205 (1.4462): Balanced strength and corrosion resistance
S32750 (2507): Extreme environments requiring superior pitting resistance
S32760 (1.4501): Maximum performance in severe corrosive conditions
Hex steel tubes offer unique advantages in structural and mechanical engineering:
Load-Bearing Structures: Our hex tubes provide exceptional performance in building frameworks, bridges, transmission towers, and industrial support structures where torsional rigidity and uniform stress distribution are critical.
Mechanical Components: The hexagonal profile enables efficient power transmission and precise torque transfer, making these tubes ideal for drive shafts, coupling assemblies, and rotational components.
Fastener Manufacturing: Hollow hexagonal bars serve as premium stock material for producing high-strength nuts, specialized bolts, and custom mechanical fasteners requiring precise dimensional control.
Material Handling Equipment: Applied extensively in lifting machinery, conveyor systems, and transportation equipment where strength-to-weight ratio optimization is essential.
Special-shaped pipes encompass a diverse range of non-circular cross-sectional profiles designed to meet specific engineering challenges. Huashang Steel's advanced manufacturing capabilities deliver precision-formed special-shaped tubes in virtually any configuration.
