扣件式钢管脚手架不同类型的工程施工一般选用不同用途的脚手架和模板支架，下面分析下扣件式钢管脚手架产品特点。

一、优点：

1、承载力较大。当尺寸及构造符合规范的有关要求时，脚手架的单管立柱的承载力可达（15kN35kN1．5tf3．5tf设计值) 扣件式钢管脚手架搭设灵活，钢管长度易于调整；

2、装拆方便。扣件连接简便，因而可适应各种平面、立面的建筑物与构筑物用脚手架。一次投资费用较低；

3、比较经济。加工简单。注意提高钢管周转使用率，扣件钢管架折合每平方米建筑用钢量约15公斤。

二、扣件式钢管脚手架的缺点：

1、扣件(特别是螺杆)容易丢失；靠抗滑力传送荷载和内力；

2、节点处的杆件为偏心连接。因而降低了其承载能力；

3、扣件节点的连接质量受扣件自身质量和工人操作的影响显著。
