Source factory, not a trader
We extrude our own sheet. Raw material, extrusion and converting stay in one place, so a technical question is answered by the people running the line.
About us
A source factory in China's lighting capital.
Zhongshan Yongshang Lighting Accessories Co., Ltd. extrudes PP and PS optical diffuser sheet in Henglan Town — the town that supplies a large share of the world's lighting industry. We have been doing it for more than 15 years.
Who we are
Yongshang is a specialised plastic sheet extruder. Our work is optical diffusion sheet, general plastic sheet extrusion and custom processing — PP and PS diffuser sheet for LED lighting, rigid PP sheet for signage, packaging and appliance parts, and PP board supplied to stationery converters.
Seven automatic extrusion lines run continuously: four for PP and three for PS. Capacity is stable enough to hold long-term volume contracts, and flexible enough that a custom grade is routine rather than a favour. Around 420 tonnes leave the factory every month.
Most of that volume goes into lighting: LED panel lights, suspended linear lights, surface-mount ceiling lights, and direct-lit or edge-lit fixtures. The same sheet also ends up in signs and light boxes, medical device displays, home appliance panels, packaging and new-energy battery protection boards.

Mission
Stay focused on sheet extrusion, keep the craft honest, and give customers stable, high value-for-money material with service they can rely on.
Vision
Keep deepening our craft in plastic sheet extrusion and become a benchmark supplier in the industry.
How we work
Four things we do not compromise on.
Virgin material only
No regrind, no fillers, no cheap blending. Purity, colour and light transmission stay consistent from the first metre to the last — which is what keeps our customers' own production lines predictable.
Built around custom orders
Non-standard thickness, size, colour, surface finish, transmittance and flame-retardant grade are the normal case for us, not the exception.
Disciplined production, honest service
Careful manufacturing, stable quality and straight answers — the simplest way to keep customers for years rather than for one order.
