Sharp Corners. Polished Finish. Structural & Decorative.
The Standard for Modern Construction.
From architectural glass railings to heavy-duty machinery frames, Square and Rectangular Hollow Sections (SHS/RHS) are the building blocks of industry.
Vertex Tubes manufactures ASTM A554 compliant square tubes with a focus on Corner Definition and Surface Consistency. Whether you need a Mirror finish for a hotel lobby or a Satin finish for an industrial rack, our tubes offer straightness and weld integrity you can trust.
Architects hate “bulbous” corners.
Controlled Radius: Unlike standard tubes with overly rounded edges, we control the forming radius to ensure sharp, crisp corners (Small R-Angle) for a modern look.
Consistency: The corner radius remains consistent throughout the entire length of the tube.
Polishing flat surfaces is harder than round ones.
Flat Polishing Tech: We use specialized flat-surface polishing heads to prevent “polishing waves” or depression on the tube face.
Mirror Quality: For large rectangular tubes (e.g., 50x100mm), the reflection is undistorted, acting like a true mirror.
Not just for looks, but for load bearing.
High-Frequency Welding: The weld seam is continuous and solid.
Flattening Test: Our tubes pass the 90° flattening test without cracking at the weld, ensuring safety for furniture frames and racks.
| Inspection Item | Vertex Factory Standard |

Rectangular tubes for handrails & posts.

Mirror polished tubes for tables & chairs.

Strong square tubes for storage systems.

Durable tubes for fences and barriers.
A: Yes. We can adjust our forming rollers to achieve a tighter corner radius (Small R) for a crisp, modern architectural look.
A: Yes. We have specialized polishing lines for wide faces (up to 100mm+ width) to ensure a uniform finish without “shadows” or “waves.”
A: Standard length is 5.8m or 6.0m (to fit containers). We can also cut to specific shorter lengths to save shipping space.
