The structure is the foundation of any greenhouse. Good design can make the difference between a greenhouse that lasts for years and one that suffers with the first storm. That's why galvanized steel is a quality standard: it resists corrosion, maintains stability and withstands the passage of time better.
Leave air passages and don't overcrowd plants to improve circulation.
- Doors and windows operational
- Adjusted watering
- Humidity control
Why galvanizing is so important
Galvanizing protects steel with a zinc coating. This offers:
- Greater resistance to moisture.
- Less oxidation in coastal or rainy areas.
- Better behavior with temperature changes.
- Longer useful life.
In greenhouses, where the environment tends to be humid, this protection is essential.
Reinforcements in arches and stability
Besides the material, design matters:
- Arches with central reinforcement.
- Firm and well-anchored joints.
- Tensioners that keep the structure stable.
These details are what make the greenhouse withstand wind and heavy rains.
Three-layer plastic at 800 gauges
The structure is complemented with quality plastic:
- UV protection.
- Good transparency for light entry.
- Resistance to tearing and tension.
With this combination, the whole setup is solid and reliable.
