Cost-effective coverage with our modular Crop Topper.
Developed from the same fundamental design as our Budget Span, Crop Toppers are fabricated from galvanised high tensile steel, with the one-piece hoop design offering superior strength.
Engineered without the Budget Span's option of crop support, it offers a clear 7 metre (23 feet) span, with the structural strength provided by heavy-duty posts. The centre of the greenhouse rises to an impressive 3.8 metres (12' 5"), providing plenty of space over your valuable crop.
Harford's patented modular system allows easy expansion in both length and width, and can easily be fitted with a windbreak or shade cloth for further customisation. Harford's only use premier covering materials 200 microns thick, wide one-piece rolls and AVA polymers to ensure long life and the best growing conditions.
Erecting the Crop Topper is easy - Harford's patented sleeve connection means simple on-site construction, saving time and money. Or enlist the help of a professional, Harford-trained team to provide a precise, efficient construction service.
