The factories
Factory No. 1 covers 5,000 square metres in the Omid Industrial City, Qom province, and holds a dedicated extrusion hall for aluminium profiles of every kind, a forging hall and a paint hall.
Factory No. 2 covers 9,000 square metres in the Mahmoud Abad industrial town and holds hot-dip galvanising, forging and welding.
That pairing is what makes the specification on these pages deliverable rather than aspirational. A greenhouse gutter that is simultaneously a beam and a drainage channel has to be extruded to its own die; a 60 µm galvanised coating on every internal face of a hollow section has to be dipped, not sprayed. Both operations are in-house.
What in-house manufacture changes
Most greenhouse suppliers assemble. Components are bought from specialist manufacturers, brought together and erected. That is a legitimate model and it works — but three things change when the components are made rather than sourced, and all three show up in the specification rather than in the sales meeting.
-
A specification written, not selected An assembler designs around the sections on offer. A manufacturer designs the section and cuts the die.
-
A coating that is a process Tank, pickling line, withdrawal rate: owning them is what makes a minimum thickness a specification rather than a hope.
-
A programme the group controls Parts made in-house arrive at a known cost and date. Bought across borders, both belong to someone else — and a growing season does not move.
Each of the three is a promise an assembler can only pass on from somebody else.
The specification can be written rather than selected. A gutter that is at once a drainage channel, a beam spanning the bay and the fixing line for everything a grower later hangs cannot be bought close enough from a catalogue. It is extruded to its own die. An assembler specifies around what is available; a manufacturer specifies what is needed and then cuts the die.
The coating is a process, not a claim. A 60 µm hot-dip coating on the internal faces of every hollow section needs a tank, a pickling line and a controlled withdrawal rate. It cannot be subcontracted to a general galvaniser without accepting whatever their bath and their throughput produce that week, and it cannot be sprayed at all. Owning the line is what makes a minimum coating thickness a specification rather than an aspiration.
Programme and cost become knowable. Components made in the group's own factories arrive at a cost and on a date the group controls. The same components bought across three borders arrive at a cost and a date somebody else controls — which matters more on a greenhouse than on most buildings, because a growing season does not move.
Where it does not help, stated honestly. Glass, climate computers, screen fabric, pumps, dosing equipment and boilers are bought from specialists, because they should be. In-house manufacture is an advantage on the structure and the envelope; on the equipment it would be a disadvantage, and a supplier who claims to make everything is either exaggerating or making some of it badly.
Where greenhouse manufacturers are, and what that means for delivery
Commercial glasshouse manufacture concentrates in a few countries — the Netherlands above all, then Turkey, China and India — and a project in Iran, Iraq, Armenia or the Gulf is normally buying from one of them and shipping. That brings a cost and a lead time set by somebody else, a warranty exercised across a border, and spare parts that arrive when they arrive.
Making the structure and the envelope in the group's own factories puts the press, the galvanising line and the fabrication shop inside the region the house is built in. For a grower in the Caucasus or the Gulf, the practical difference is not the price of the steel. It is that a replacement gutter section is extruded from the same die that made the original, and it comes from within the region rather than in a container from Rotterdam.
From drawing to component
The sequence is deliberately short. Design is checked by engineering software; the shop receives fabrication-ready drawings; production planning is done by a team that has built the same components before; and quality control runs at every stage from the initial design to the final check, rather than as an inspection at the end.
A greenhouse is a repeating structure, which cuts both ways. A component that is right is right two hundred and fifty times; a component that is 3 mm out is wrong two hundred and fifty times, and the error only becomes visible when the glazing arrives.
One party, one responsibility
Producing the steel and the aluminium in our own plants removes the interface where most greenhouse projects lose time: the point at which a structural drawing meets a supplier's standard section and someone has to decide who adapts.
It is the same reasoning that runs through the façade side of this company, and the same presses. Sections are developed for the project instead of being selected from a catalogue, and that freedom is what makes a demanding detail affordable rather than merely possible.
