2.1生产质量
　　近几年来，国内的民营脚手架租赁公司如雨后春笋般的成立起来，在搞活租赁市场的同时，因政府主管部门在某些方面的管理措施不到位，造成了脚手架市场的无序竞争，因片面追求利润致使一些材质差、壁薄的扣件钢管投放市场，如某些厂生产的扣件价格仅5～6元／只，脚手架钢管壁厚只有2.5～2.75mm，严重扰乱了建筑脚手架市场的正常发展，存在着严重的质量安全隐患并在近年发生了多起重大安全事故。如浙江省质量技术监督部门最近抽检了用于搭建建筑工地脚手架的45批次钢管和39批次扣件，结果是扣件合格率为零，钢管合格率也仅为14％。据质监部门介绍，目前浙江共有2万余个工地在施工，数以百万计建筑工人的生命安全时刻受到威胁。
