Square tube

Square Tube | High-Strength Structural Steel Tubing

A square tube is a hollow steel pipe without galvanization, commonly used in construction, machinery, transportation infrastructure, and more. With its high strength, excellent processability, and cost-effectiveness, it is a popular choice for structural applications.

📌 Manufacturing Process

① Raw Material Preparation – Hot-rolled or cold-rolled steel strips are selected to ensure stable quality
② Forming – The steel strips are processed into a square cross-section using cold bending or welding techniques
③ Welding – High-frequency welding is applied for uniform and durable seams
④ Sizing & Straightening – The tubes are calibrated to precise dimensions with a smooth surface
⑤ Cutting & Inspection – Custom lengths are cut according to customer needs, followed by quality inspection

📌 Key Features

🔸 High Strength & Stability – Excellent load-bearing capacity for structural applications
🔸 Great Processability – Suitable for welding, cutting, and assembling, adaptable to various designs
🔸 Cost-Effective – More affordable than galvanized square tubes, making it ideal for budget-conscious projects
🔸 Durability – Though ungalvanized, it remains durable in dry environments or with proper coating

📌 Applications

🔸 Construction & Structures – Building frameworks, steel structures, storage racks
🔸 Machinery & Equipment – Industrial machinery supports, mechanical frames
🔸 Furniture & Interior Design – Table & chair frames, display racks
🔸 Transportation Infrastructure – Guardrails, parking barriers, providing strong and durable support
🔸 Agriculture & Greenhouses – Farm greenhouse frames, livestock enclosures, with flexible design options
