目前国内有专业移动脚手架厂数百家，还有许多家庭作坊式的小厂，如河北某地区有许多生产碗扣式脚手架和配件的家庭小厂，采用钢管的管壁厚度和材质均不合格，有些厂还采用旧钢管加工脚手架。广东佛山地区有40多家脚手架企业，主要生产门式脚手架。

At present, there are hundreds of professional scaffolding factories in China, as well as many small family workshop-like factories. For example, there are many small family factories producing bowl-buckle scaffolding and fittings in a certain area of Hebei Province.

There are more than 40 scaffolding enterprises in Foshan, Guangdong, which mainly produce portal scaffolds.

江苏无锡地区有60多家移动脚手架企业，可以生产门式、碗扣式和插销式等各类移动脚手架。大部分企业的生产规模都很小，设备简陋，生产工艺落后，产品质量很难保证，产品价格也很低。这些企业为了抢占市场，相互进行恶性竞争，结果是产品价格越来越低，企业利润越来越少，产品质量越来越差，最后严重影响产品的发展前景。无锡有不少门式脚手架企业是专门对外商加工，由于这些厂的无序竞争，相互压价，结果企业利润很低，大部分利润都给了外商。

There are more than 60 scaffolding enterprises in Wuxi, Jiangsu Province, which can produce various scaffolding such as door type, bowl button type and plug type. The production scale of most enterprises is very small, the equipment is simple, the production technology is backward, the product quality is difficult to guarantee, and the product price is also very low. In order to seize the market and compete with each other viciously, the result is that the price of products is getting lower and lower, the profit of enterprises is getting less and less, and the quality of products is getting worse and worse. Finally, the development prospect of products is seriously affected. There are many scaffolding enterprises in Wuxi specializing in foreign processing. Because of the disorderly competition among these factories and the mutual depreciation, the profits of the enterprises are very low, and most of the profits are given to foreign investors.
