Product Overview
PC840/PC900 medium wave corrugated polycarbonate sheets feature a 24mm wave height with 84mm and 90mm pitch respectively, offering the ideal balance between structural strength and daylighting performance. These medium-profile sheets are specifically designed to be compatible with standard color steel tile purlin systems, making them the preferred choice for industrial and commercial roofing renovation projects where both light transmission and load-bearing capacity are required.
Manufactured from high-quality polycarbonate resin with UV-resistant co-extrusion coating, these sheets provide exceptional weather resistance, impact strength (approximately 200 times that of glass), and thermal stability across a wide temperature range (-40°C to 120°C). With a 10-year manufacturer warranty against UV degradation, they deliver long-term value for professional building projects.

Application Scenarios
Industrial Factory Roofing
For large-scale industrial factory buildings requiring both natural daylighting and structural integrity, PC840/PC900 medium wave sheets provide an optimal solution. The 24mm wave height delivers sufficient load-bearing capacity to withstand wind and snow loads, while maintaining excellent light transmission to reduce daytime electricity consumption for lighting. Recommended thickness: 1.5mm – 2.0mm.
Warehouse and Logistics Centers
Warehouses benefit from the combination of natural lighting and thermal insulation offered by medium wave PC sheets. The multi-wall structure provides better thermal performance than single-layer alternatives, helping to maintain stable interior temperatures for stored goods. Milky or blue color options provide light diffusion and heat control.
Commercial Canopies and Carports
For commercial applications such as canopy roofing, carport covers, and walkway shelters, PC840/PC900 sheets offer an attractive and durable solution. Their compatibility with standard metal substructures simplifies installation, while the UV protection ensures long-term clarity and color stability.
Installation Guidelines
- Purlin spacing: recommended maximum 1.2m for 1.5mm thickness
- Side lap: minimum 1.5 waves (one full crest plus half wave)
- End lap: minimum 200mm on purlin support
- Fasteners: self-tapping screws with EPDM sealing washers, installed at every third corrugation crest
- Drill holes: pre-drill with 2mm larger diameter than screw to allow thermal expansion
- Sealing: neutral silicone sealant at all end lap joints
- Cutting: fine-tooth saw blade, deburr edges after cutting
- Storage: keep protective film intact during installation, remove immediately after completion
