PC840/PC900 Medium Wave Profile Overview
PC840 and PC900 polycarbonate corrugated sheets (Medium Wave Profiles) are the most popular roofing daylighting solutions in the industrial building sector. With a pitch of 84mm/90mm, moderate wave height, and excellent structural strength, they are especially suitable for large-span building roofs such as industrial factories, logistics warehouses, and production workshops. Medium wave sheets achieve a perfect balance between structural strength and daylighting performance, capable of withstanding industrial load requirements while providing ample natural light to reduce daytime lighting energy consumption.

Industrial Factory Application Advantages
Modern industrial factories demand extremely high performance from roofing materials — they must bear structural loads, provide good daylighting, and meet fire safety and other standards simultaneously. PC840/PC900 medium wave sheets are the ideal choice for industrial factories thanks to the following advantages:

1. Superior Structural Strength: PC840/PC900 features an optimized wave profile design with a wave height of 24mm, offering better flexural strength and load capacity than small wave sheets. They can withstand common industrial loads such as snow, wind, and maintenance loads. Panel thickness can reach 2.5mm to meet the most demanding engineering requirements.
2. Energy Efficiency and Natural Lighting: The clear series offers 88% light transmission, significantly reducing daytime workshop lighting electricity consumption. By strategically placing skylight strips (e.g., installing one PC corrugated sheet every 3-5 meters), uniform internal lighting can be achieved with remarkable energy savings. The milky series provides soft light diffusion to reduce glare and improve the working environment.
3. Weather Resistance and Long Lifespan: The panel surface features a 50μm UV co-extrusion layer that effectively resists UV aging. Stable performance is maintained across a temperature range of -40°C to +120°C, with a service life of over 15 years — far exceeding traditional FRP skylight sheets (which typically yellow and become brittle after 3-5 years).
Warehouse Roofing Application

4. Easy Installation: PC840/PC900 perfectly matches standard color steel tile profiles, allowing direct replacement or combined use without special fittings. The panels can be cold-formed to suit various roof structures. Custom lengths are available to reduce lateral overlaps and improve waterproof performance.
5. Fire Safety: PC corrugated sheets achieve UL94 V-2 flame retardant rating — self-extinguishing upon flame removal, meeting industrial building fire safety standards. When combined with steel structure fire protection design, overall building safety is ensured.
6. Economic Analysis: Although the initial cost of PC corrugated sheets is higher than FRP sheets, considering a service life of over 15 years with near-zero maintenance requirements, the full lifecycle cost is far lower than FRP. Combined with electricity savings from improved lighting, the investment is typically recovered in 2-3 years.
