Custom Roof Panels for Curved Structures

"An aviation hangar in Dubai used custom-bent polycarbonate roof panels to fit its arched design. Sinhai’s team provided precision-cut sheets that matched the curvature perfectly, ensuring a watertight seal. The impact-resistant material withstands high winds, and the clear finish allows natural light, reducing reliance on artificial lighting. Impressive engineering."

Cost-Effective Roof Panels for Agricultural Buildings

"A barn in Australia used Sinhai’s corrugated polycarbonate roof panels to replace traditional metal sheets. The lightweight panels were easy to transport to remote locations, and the UV-resistant coating prevents yellowing from prolonged sun exposure. The corrugated design enhances water runoff, and the 10-year warranty provided peace of mind."
