The Greenhouse Door Roller is a professional-grade, precision-engineered metal roller specifically designed for sliding door systems in agricultural and horticultural environments. Crafted from high-strength carbon steel with a premium zinc galvanized coating, these rollers provide critical support for door weight while ensuring seamless movement along tracks, even in high-humidity outdoor conditions.
Designed for versatility and long-term durability, our rollers support both lightweight polyfilm and heavy-duty polycarbonate or steel-framed doors. With flexible installation options including pre-drilled bolt-on and weld-on configurations, these components are the ideal choice for both new greenhouse constructions and retrofit projects requiring reliable, low-maintenance hardware.

Frequently Asked Questions
For aluminum profiles or modular greenhouses, we highly recommend the Pre-drilled Bolt-On method. It allows for fast installation and easy replacement without damaging the frame.
Yes, they are constructed from high-strength carbon steel and can support up to 150 kg per roller, making them ideal for heavy polycarbonate or steel-framed structures.
Greenhouses are high-moisture environments. The zinc coating acts as a sacrificial layer that prevents oxidation and rust, significantly extending the hardware's life compared to raw steel.
Absolutely. While we offer standard 63mm and 100mm wheels, we provide full OEM support for custom wheel diameters and mounting base dimensions to fit your specific track system.
Yes, they are frequently used in tunnel greenhouses for roll-up or sliding panels, enabling easier ventilation and access for workers and machinery.
Our bearings are tested for over 10,000 open-close cycles. Depending on the environment and load, they typically provide several years of maintenance-free operation.
