Glass is the cover for growers who want the envelope to stay the same for twenty years while the growing system inside it changes. This listing quotes an eight millimetre glass house on a hot dip galvanized frame, in spans from eight to twelve metres, lengths from ten to a hundred metres and heights from three to eight metres, built for commercial vertical farming. The intelligent part of the title is a control package rather than a fixed specification, so it is scoped at quotation against the systems you actually plan to run.
A vertical farming project usually starts with the growing system and then asks what to put around it. Glass is the answer when the crop needs consistent light for years and the house is expected to outlast several generations of racks. This page covers the eight millimetre glass house in this listing, part of the hydroponic greenhouse range on this site.
Thicker glass resists impact and deflects less under wind, and it carries its own weight over a wider span between glazing bars. The trade-off is weight on the frame and on the foundation, which is why the frame here is hot dip galvanized steel rather than aluminium. On a commercial house the decision is usually made on hail risk and on how long the owner intends to keep the structure.
The listing quotes spans from eight to twelve metres, lengths from ten to a hundred metres, and heights from three to eight metres, all built to order. For a vertical system the height is the number that matters most: a three metre column suits a single tier with working clearance, and the upper part of the range is there for stacked racks and for the air volume that stacking needs.
Length is a layout decision rather than a structural one. A long single run gives a sprayer or a harvest trolley a straight path, and it spreads the ventilation load along one ridge line instead of several gable ends.

The word intelligent in the product name refers to a control package, and the listing does not itemise which functions it includes. On a vertical farm the useful list is short: vent opening, shading, irrigation and dosing, and the lights. Ask for the point list with the quotation, and check whether sensors, controllers and actuators are one line or three.
Two practical points on controls. First, a glass house changes temperature faster than a film one in strong sun, so vent and screen response times matter more than the number of features. Second, every controller needs a manual override, because a failed sensor in a closed house is a crop event rather than an inconvenience.
Racks, gutters and lights hang from the truss, and their weight is continuous rather than seasonal. A glass house frame is designed for cover loads plus wind and snow; adding a stacked system means adding point loads at the truss nodes, and those are worth putting on the drawing before the steel is cut.
A Venlo glass house for a vertical crop is described on the Venlo glass vertical house page, and a Venlo house built around hydroponic gutters on the Venlo house with hydroponic gutters page.
The frame is shipped flat, marked and drilled, and assembled on site with bolts. Glass follows the frame, so the sequence is foundation, frame, glazing, then the internal systems. A house that may gain bays later should have its end wall detailed as an intermediate frame from the start.
Standards for structural glass and for greenhouse construction are published by CEN, and vertical farming coverage by Vertical Farm Daily.
The hot-dip galvanized steel frame is designed for a 15-20 year service life in normal agricultural environments, with a double-sided zinc coating of 200-275 g/m². Film covers are replaced every 3-5 years, while glass and PC panels carry their own manufacturer warranties.
A standard multi-span greenhouse is typically erected in 2-4 weeks, depending on the span, the number of bays and site access. Foundation work and glazing are the two stages that set the pace, and both are scheduled before the frame arrives.
Yes. We customize span width, bay length, gutter height, covering material (film, PC sheet or glass) and ventilation configuration. Share your crop type, local climate and growing area, and our engineers will size the structure to match.
Ziyang Bozong Greenhouse Industry Co., Ltd. is a manufacturer based in Ziyang, Sichuan, China. We produce the hot-dip galvanized steel frame in-house, cutting and drilling to drawing, and supply covering materials, ventilation, cooling and irrigation systems as one coordinated package.
The listing names an intelligent control package but does not itemise it, so treat it as a line to confirm. Ask for the point list, the controller make and whether sensors and actuators are included. On a vertical farm that list is what the price difference between two suppliers usually comes down to.
Yes, glass is replaced panel by panel, which is one of its practical advantages over a film cover that has to be recovered in large sheets. Keep a spare pane of each size on site; a broken panel in a storm is quick to fix if the glass is already there.
