PC930/PC970 Large Wave Profile Overview
PC930 and PC970 polycarbonate corrugated sheets (Large Wave Profiles) are heavy-duty roofing daylighting systems designed for large-span buildings and high-load scenarios. With a pitch of 93mm/97mm and a wave height of 30mm, they are the structurally strongest products in the PC corrugated sheet series. Thanks to their exceptional load-bearing capacity and clear daylighting performance, large wave sheets are widely used in iconic large-span buildings such as stadiums, exhibition centers, airport terminals, and high-speed railway station canopies.

Stadium and Large-Span Building Applications
1. Ultra-Large Span Roofing System
Large-span buildings demand extremely high strength and stiffness from roofing materials. PC930/PC970 large wave sheets feature a 30mm wave height and an effective width of 930-970mm. Combined with panels up to 3.0mm thick, they easily handle large purlin spacings (up to 1.5m or more). Their excellent flexural stiffness ensures flatness and stability across ultra-large spans without noticeable sagging or deformation.
Compared to traditional metal roofing, PC large wave sheets solve both daylighting and structural needs simultaneously — no additional skylights or light strips are required, and the entire roof provides uniform natural lighting for a cleaner, more streamlined architectural design.
2. Exceptional Load Capacity
Snow Load Resistance: The wave profile design of large wave sheets provides excellent longitudinal and transverse flexural strength, capable of withstanding heavy snow loads in high-latitude regions. A 3.0mm thick large wave sheet can bear snow loads exceeding 1.5 kN/m².
Wind Load Resistance: When paired with professional fastening systems, large wave sheet roofing can withstand typhoons of category 12 and above, making it suitable for sports venues and public buildings in coastal typhoon-prone areas.
3. Superior Lighting Environment
Stadiums and public buildings have stringent lighting requirements. The clear series of PC large wave sheets offers 85% light transmission. Combined with proper building orientation and roof slope design, natural daylight can fully meet interior lighting needs during the day, significantly reducing lighting energy consumption. The milky series provides soft diffused light, eliminating glare, and is especially suitable for indoor sports venues, swimming pools, and other spaces requiring uniform light distribution.
Other Application Scenarios
Beyond stadiums, PC930/PC970 large wave sheets are widely used in:
- Exhibition centers / Convention center roofing
- Airport terminals / High-speed rail station canopies
- Large shopping mall atrium skylights
- Swimming pools / Indoor water park roofing
- Multi-story parking garage roof lighting
- Eco-restaurants / Botanical garden greenhouse domes
