Oval tube greenhouses:
Maximum strength and luminosity
Oval-tube greenhouses represent a major advance in the construction of agricultural structures, as they provide two main benefits: greater light entry into the interior by reducing the use of iron in the truss, and faster and easier installation, resulting in significant savings in labor and assembly costs.
These advantages are complemented by the exclusive innovations of J. Huete Greenhouses, which combine the oval tube with new, reinforced capital designs and 100×100 pillars. Thanks to this structural integration, spans of up to 4 meters can be achieved without the need for intermediate trusses, optimizing growing space, improving ventilation, and increasing the overall efficiency of the greenhouse.
Why choose an oval tube greenhouse?
Advantages of the oval tube over the traditional tube
The structure of a greenhouse is crucial to ensuring its durability, safety, and efficiency. While conventional round tubes have been the standard for decades, oval tubes are establishing themselves as a superior alternative thanks to a series of technical and agronomic advantages.
The main advantage of oval tubing is that it eliminates the need to install trusses with large poles. This translates into two key benefits: greater light penetration for crops by reducing the amount of ironwork casting shade, and much simpler and faster installation, with consequent savings in labor and assembly costs.
Greater luminosity inside
Superior rigidity with less material
Greater structural strength and easy assembly
Better behavior against condensation
Oval tubes offer key advantages over traditional tubes, primarily by reducing the need for iron in the truss.
This translates into two direct benefits: greater light entry into the greenhouse and much faster and easier installation, which significantly reduces labor and assembly costs.
Another important aspect is that, by casting fewer shadows, natural light is increased, promoting photosynthesis and improving crop yield. Furthermore, their geometry optimizes condensation drainage, preventing water accumulation and creating a healthier environment for plants.
An exclusive innovation
In terms of structural strength, the oval tube performs better under vertical loads, provided it is accompanied by appropriately designed pillars and capitals. In the case of J. Huete Greenhouses, the incorporation of reinforced 100×100 pillars and a new, unique capital allows spans of up to 4 meters to be achieved without the need for intermediate trusses.
Key structural elements in oval greenhouses
The innovation of the oval tube is not limited to the main arches. State-of-the-art greenhouses incorporate a series of structural elements designed to maximize strength, durability, and assembly efficiency. These include pillars, channels, and capitals, which form the core of the structure and ensure its long-term optimal performance.
Our design and innovation team has made a number of improvements you won’t find with other vendors:
Reinforced and adaptable pillars
Flat-sided pillars are the foundation of any greenhouse’s stability. In oval-tube models, these components are manufactured with reinforced sections that offer superior resistance to wind, snow, and crop loads. Their design allows for different dimensions to be chosen depending on the project’s needs.
In addition, the possibility of extending the spacing between pillars to 4 meters (100x100mm) provides better access to sunlight for the crop, greater interior volume, and improved air circulation, optimizing conditions for the development of any plant.
Pillars available in 100x100mm and 80x80mm.
Gutters with quick coupling and improved tightness
The gutters serve a dual purpose: efficiently draining rainwater and reinforcing the durability of the structure. In J. Huete Greenhouses’ oval greenhouses, the new generation of gutters includes a quick-connect system that facilitates on-site assembly and guarantees safe and efficient installation. Thanks to their optimized design, the joints are more tightly sealed, preventing leaks and ensuring long-lasting protection against the most demanding weather conditions.
Optimized capitals for maximum durability
The capital is the focal point where arches, pillars, and channels meet, and our innovative design is crucial to its overall strength.
It is, in short, the heart of the greenhouse.
The capitals of our oval model stand out for their superior thickness and integrated reinforcing ribs. They also incorporate technical details such as preparation for condensation channels and optimized support for the arches, ensuring even load distribution.
All of this results in easier and more efficient assembly, greater structural safety, and long-lasting durability even in highly demanding environments.

Technical comparison: round tube vs. oval tube
The difference between a greenhouse built with traditional round tubing and one designed with oval tubing is significant, both in terms of strength and production efficiency. While round tubing has been the standard for many years, the development of oval tubing has allowed for a higher level of strength, space utilization, and light output.
However, J. Huete Greenhouses has implemented several improvements to this greenhouse model, particularly in the new capitals and pillars, to increase its strength.
From a structural perspective, the oval tube offers 40% greater strength and up to 66% less deformation than conventional tubes, resulting in a more stable and durable installation that can withstand wind, snow, or crop overweight. Furthermore, since it requires fewer reinforcements and casts fewer shadows, it significantly improves the entry of natural light, promoting photosynthesis and increasing agricultural yields.
In terms of construction efficiency, the oval tube combined with our capital and 100×100 pillars allows for an extension of the spacing between pillars up to 4 meters, offering greater interior volume and improved ventilation, while reducing material usage and streamlining assembly. All this translates into lighter structures that are easier to install and more cost-effective in the long run, consolidating the oval tube as the most advanced option for modern greenhouses.
