The Greenhouse Door Roller is a professional-grade engineering solution designed specifically for sliding door systems in agricultural and industrial greenhouses. Precision-crafted from high-strength carbon steel and finished with a premium zinc galvanized coating, these rollers provide essential support for heavy door panels, ensuring seamless movement along the track even in the most demanding environmental conditions.
Engineered for versatility and longevity, our rollers are optimized for high-humidity and outdoor exposure, effectively preventing rust and wear. Whether you are managing a modular polyfilm structure or a permanent steel-framed polycarbonate facility, these rollers offer the structural integrity and smooth operation required to maintain efficient facility access and ventilation.

Frequently Asked Questions
For aluminum profiles, the Bolt-On (Pre-drilled) method is highly recommended. It allows for quick mounting using galvanized bolts and offers the flexibility to replace or adjust the rollers without damaging the frame.
Our zinc coating creates a sacrificial protective layer that prevents oxidation. This is critical in greenhouse environments where high humidity and chemical fertilizers typically accelerate rust in standard carbon steel.
Yes, these rollers are versatile. Many clients utilize them as track gliders for mobile partitions or side curtain systems due to their high load capacity and smooth sliding mechanism.
Depending on the wheel diameter (63mm or 100mm), our rollers can support up to 150 kg each. For heavier doors, we recommend installing multiple rollers to distribute the weight evenly.
Absolutely. We provide full OEM support. If our standard 63mm or 100mm wheels do not fit your tracks, we can produce custom wheel diameters and mounting base dimensions to your specifications.
We recommend positioning the steel base on the track mounting point and checking for tilt before final MIG or arc welding. Proper alignment prevents door misalignment and ensures the longest possible bearing life.
