Sinhai’s corrugated greenhouse sheets are engineered to optimize light distribution and thermal insulation for agricultural applications. The 0.75–2mm thickness range balances light transmittance (75–80%) with structural integrity, while the corrugated texture diffuses light evenly to reduce glare and hotspots. Treated with anti-fogging additives, these sheets minimize condensation in humid environments, supporting plant health. They are UV-stabilized for 10-year durability and compliant with EN 16240 standards for greenhouse materials. Sinhai’s global logistics network delivers to over 180 countries, with fast turnaround from their Baoding and Kashgar facilities. Contact us for greenhouse-specific solutions and bulk pricing.

Stylish Corrugated Sheets for Outdoor Structures

"In my backyard pergola in California, I used Sinhai’s bronze corrugated sheets. The texture adds visual interest, and the UV-blocking layer keeps the area cool. The sheets are easy to attach to the wooden frame, and the weatherproof seal has prevented leaks during heavy rains. A perfect blend of form and function."

The corrugated design enhances airflow, reducing heat buildup, and the easy-to-clean surface is a bonus for coastal maintenance. Exceptional product."
