GB/T3094 Steel Pipe

As a specialized seamless steel tube manufacturer with 21 years of industry expertise, Tenjan produces GB/T 3094 cold-drawn special-shaped steel tubes that represent the pinnacle of custom profile manufacturing. Our precision-shaped steel tubes are engineered through advanced cold-drawing technology to deliver exceptional dimensional accuracy, superior surface quality, and optimized mechanical properties for specialized structural applications. With our experienced 30-year R&D team, we provide global clients with custom cross-section solutions that combine innovative engineering with cost-effective manufacturing.

For GB/T 3094 cold-drawn shaped tube, provide the complete profile drawing with datums, flats, angles, corner radii, wall requirements, straightness, twist and cut length. Identify the dimensions that control assembly instead of assigning the same tolerance to every feature.

• Material grade and delivery condition
• Critical profile and wall-thickness measurement points
• Surface and downstream welding or machining requirements
• First-article report, checking fixture or scanning method

Feasible grades and profiles depend on material flow, reduction schedule, tooling and heat treatment. Tenjan can review a 2D drawing and 3D model, then propose starting stock, tooling stages and a sample-validation plan.

Cold-drawn shaped tubes can reduce machining and simplify assembly in machinery, vehicle, agricultural and structural components. The best result comes from reviewing profile geometry, material, tooling, volume and downstream operations as one design rather than treating the tube as a catalogue size.
