SPRING SIGN has the world leading double-sided UV co-extrusion production line that uses the new imported PC materials of BAYER and GE and has an annual output of 10,000t.To enhance the competitiveness of products,we spend much money on building a testing lab to substantiate quality control and inspection strength.
Credible,Professional,Efficient and United are SPRING SIGN's unswerving pursuit of the goals. We set up affiliated branches in major cities throughout the nation and have sales outlets across the country.Meanwhile, our factories directly supply greenhouse PC multiwall products to a number of domestically top greenhouse companies. SPRING SIGN PC multiwall sheet has been widely applied to many agricultural greenhouse projects and is widely praised by users.
SPRING SIGN has always been praised by architecture and greenhouse industries with good products quality and improved after-sales service.
SPRING SIGN is willing to work together with the professional partners for a brilliant tomorrow of PC multiwall sheet!

PC Solid Sheet types:
PC General-purpose Solid Sheet
PC Embossed Solid Sheet
PC Diffused Sheet
PC Soundproofing sheet
PC Anti-scartch Sheet
PC Anti-Electrostatic Solid Sheet
The quality of UV granule and co-extrusion machinery and technology determines the durability of UV functions.Therefore, SPRING SIGN chooses first-class UV granules, adopts the advanced in-the-mold co-extrusion technology to ensure the reliable thickness and uniformity of the co-extrusion layers,guaranteeing the weather resistance and service years of SPRING SIGN sheets.
SPRING SIGN polycarbonate solid sheets have excellent impact resistance and as compared with glass, they are half of the weight. Meanwhile,their ignition point is extremely high and the sheets are not prone to crack.They come in various colors and can be cold bent,hot bend and shaped,being the ideal choice for the large lighting engineering.Thanks to the excellent expertise,on the basis of the ordinary sheets,SPRING SIGN adds new raw materials and improves the processes to produce the embossed sheets,diffused sheets,scratch resistance sheets and anti-static sheets,which are widely used in architectural lighting,indoor and outdoor decoration, advertising,lamps and lanterns,instrument panels,safety protection,sound barriers on roads, medical equipment and other usages.Thanks to the stable physical properties,they are preferred sheet for all kinds of engineering and products.
Half weight of glass
30 times impact resistance of tempered glass
50u UV layer, fiter ultraviolet radiation

PC General-purpose Solid Sheet
PC solid sheet weighs 50% of that glass with the equivalent thickness but provides the impact strength 30 times that of the tempered glass with the equivalent thickness.It is absolutely the best substitute of day lighting glass.The property that it is unbreakable provides the highest safety in day lighting materials especially in roof day lighting application.The surface co-extrusion layer treated with UV maintains the good light transmittance.The solid sheets come in various colors and meet the needs for different looks and transparency.
Applications
Building skylights,Curtain wall Sightseeing lift,Advertising light boxes,Museum show box,Sound barrier,Observation window,Safety glasses and veil

PC Embossed Solid Sheet
SPRING SIGN PC Embossed Solid Sheet has uneven surfaces to effectively improve the barrier property and reflect the direct radiation from high lights on the sheets.The reflected light rays are diffused so that these rays are softer and it also reduces light pollution.

Applications
Bathroom /upholster,lighting, Indoor partition/folding screen sunshades,ceiling
PC Diffused Light Diffusion Sheet
PC diffused sheet makes light constantly refract,reflect and scatter between diffusive particles and base material so as to reach a homogenous diffusion.Our products have a high transmittance and excellent brightness,and completely lighting without residual images.What's more,LED light sources cannot penetrate PC diffusers and its thermal stability keeps itself from yellowing.
Applications
Advertising light box,Shop sign,outdoor billboard,LED display panels,stage decoration
PC Soundproofing Sheet
PC transparent acoustic sheet is specially designed for facilities that require sound insulation,such as roads, viaducts,expressways,rail transits,railways,residential communities,etc.It provides better sound insulation effect and higher aging and impact resistance ability compared to common sheets.The sheet can effectively prevent the accidents due to falling of the acoustic barrier as a result of collision of the vehicles with other factors.With the natural bending property under room temperature,a more perfect acoustic barrier can be designed.The quality assurance is offered for 10-15 years.
Applications
The highway,the railroad sound barrier,sound barrier tunnel,
The sound-insulated plate for residential district
PC Anti-scratch Sheet
The surface has anti-scratch coating with high hardness and is easy to clean.It has very high impact resistance strength and transparency and is weatherproof and UV-resistant.The sheet is applied to wide range of temperature and has low weight.
Applications
Car,electronics and electrical appliance industries,bank counter,industrial mechanical part and coated mirror, protective shield,model shell etc
