Yongshang sheet extrusion workshop in Henglan Town, Zhongshan

About Yongshang

A source factory for optical diffusion sheet.

Yongshang has been extruding PP and PS sheet for more than 15 years from Henglan Town, Zhongshan City, Guangdong. Our focus is optical diffuser sheet, general plastic sheet extrusion and custom processing — and we run the whole process ourselves rather than buying sheet in.

Every batch is produced from 100% virgin material: no regrind and no fillers. That is why purity, colour and light transmission stay consistent from the first metre to the last, and why our customers’ own production lines stay predictable.
