Unverified管径决定稳定性：钢管选直径≥25mm、壁厚≥0.8mm，铝合金因材质软需≥28mm或加粗方管，管径低于22mm的伸缩架横向晃动明显、不适合挂载重物91% similarUnverified钢管挂衣架管壁厚度是稳定性关键，管壁≥1.0mm、主管径≥25mm的产品才能避免挂满衣物后弯曲变形；廉价产品管壁常低于0.7mm，一年内易塌陷89% similarUnverified免组装床架的钢管管径直接决定承重上限，主承重横梁管径≥25mm且壁厚≥1.0mm可稳定支撑200kg以内，管径＜22mm或壁厚＜0.8mm易出现中间塌陷和异响87% similarUnverified管径是稳定性关键：25mm以上不锈钢管管壁厚度≥1mm才能承受横臂力矩，铝合金架轻便但同管径承重比钢架低约30%87% similarUnverified落地式引体架的钢管壁厚是稳定性核心指标：主承重立柱管壁厚度应≥1.5mm、管径≥50mm，薄壁管在高负荷下会出现明显晃动和长期形变86% similar
