正方形截面方管，用於立柱、框架和支撐結構。
實務注意事項
- 用於需要四面等強度的柱、腿和支撐結構。均勻抵抗扭轉。
- 注意焊接殘餘應力引起的變形。交替兩側焊接可最小化變形。
選型指南
用於需要四面等強度的立柱、支腿和支撐結構。直角焊接方便，抗扭均勻。一般框架：t2.3–3.2mm；重載：t4.5–6.0mm。

- KS D 3568 (SPSR) 標準，邊長範圍□12–□400 mm
- 四面等截面係數，均勻抵抗多軸載荷和扭轉
- 焊接組裝時直角對接方便，切割面可直接作為接合面
主要應用領域
建築柱/立柱、機械框架、護欄、標牌支柱、家具結構
常見問題
方管壁厚如何選擇？
一般框架：t2.3-3.2mm；重載：t4.5-6.0mm。正規做法是通過結構計算確定所需截面積和截面模量。
