Comparing sandwich panel enclosures with simple galvanized sheet enclosures: Which is more economical for your project?
The constant dilemma in purchasing enclosures
One of the most important challenges for contractors, construction project managers, and even individual buyers when equipping a workshop or building a prefabricated villa is choosing the type of enclosure body material. Usually, the first question asked of Sabat Sanat experts is: "Is the higher cost of purchasing a sandwich panel enclosure economically justified, or will a simple galvanized sheet enclosure get our business started?"
In this specialized article, we intend to compare sandwich panel enclosures with simple galvanized sheet enclosures from an engineering perspective and without prejudice, so that you can make the best and most economical choice based on your budget, climate (especially the humid conditions of Mazandaran), and type of use.
What is a simple galvanized sheet enclosure?
Galvanized sheds are the most traditional and well-known type of prefabricated structures. In these structures, the metal frame (framework) is covered with galvanized sheets (sinusoidal or trapezoidal). For insulation of this model, plastofoam (Unilite) is usually used between the outer wall and the inner covering (such as PVC wall coverings).
Advantages of galvanized sheet sheds
- Lower initial price: The most important reason for the popularity of these sheds is their lower cost, which is very attractive for short-term projects.
- High construction speed: The production process of these sheds is faster.
- Light weight: They are easier to move in temporary workshops.
Disadvantages of simple galvanized sheds
- Weaker insulation: Unilite deteriorates over time and is not 100% resistant to extreme cold and heat.
- Less resistance to moisture: Although the sheets are galvanized, if there is no precise sealing (which usually occurs in workshop and under-stairs production), moisture will penetrate inside.
What is a sandwich panel container?
A sandwich panel container is a new and advanced generation of prefabricated structures. As its name suggests, the walls and roof of this structure are made of sandwich panels. The sandwich panel has a three-layer structure: two layers of steel sheets (aluzinc or galvanized) and a very strong insulating core made of polyurethane foam that is injected and closed-celled between the sheets.
Advantages of sandwich panel containers
- Unrivaled heat and cold insulation: Polyurethane foam is the best known insulation in the industry and brings temperature exchange close to zero.
- 100% moisture resistance: For climates like Mazandaran, these cabins are completely waterproof and rot-proof.
- High structural strength: The integrated structure of the panels greatly increases the cabin's resistance to wind, storms, and impacts.
Analytical comparison: Which one is more economical?
To answer the question of which structure is more economical for you, we need to examine the following factors:
1. Energy consumption costs (winner: sandwich panels)
In very cold, very hot, or humid regions, the cost of heating and cooling the cabin is extremely high. Sandwich panel cabins reduce energy loss by up to 80% due to polyurethane insulation. Therefore, if your project is long-term, the money you save on electricity or fuel bills will fully compensate for the initial price difference.
2. Lifespan and Depreciation (Winner: Sandwich Panel)
Simple galvanized containers with Unolith insulation usually need to be renovated after a few years. However, a sandwich panel container has a lifespan equivalent to a brick building and remains in good condition for years without any loss of quality.
3. Initial Price and Purchase Budget (Winner: Galvanized Sheet)
If your project is a short-term project of 3 to 6 months, or you just need a simple warehouse, purchasing expensive structures is not financially justified. In these circumstances, purchasing a galvanized sheet container produced in a reputable factory is completely economical and logical.
Sabat Sanat; Quality Assurance in Both Models
One of the fatal mistakes in purchasing a container is going to unauthorized workshops. Whether you want a galvanized sheet container or a sandwich panel container, factory production is the first condition for quality.
At Sabat Sanat factory located in Mazandaran:
- All chassis drawing stages are carried out using heavy industrial profiles and under the supervision of structural engineers.
- Using overhead cranes to move the structure prevents any tension and warping in the joints.
- The sheet forming process and complete sealing are carried out professionally within the complex itself.
Frequently Asked Questions
1. Is the price difference between sandwich panel and galvanized containers too high?
Depending on the thickness of the sheet and the type of insulation, sandwich panel containers are more expensive at the time of initial purchase (about 30 to 50 percent). However, given the significant reduction in energy costs and very long service life, this price difference is completely justifiable and economical in the long run.
2. Is galvanized sheet containers suitable for the humid climate of the north?
Galvanized sheets have good resistance to rust; But if the container is made in a workshop and non-standard conditions, water will penetrate through the seams and screws. In Sabat Sanat factory production, specialized sealing and flushing are performed. However, for the Mazandaran climate, we always recommend sandwich panels as a definitive moisture-proof option.
3. Is it possible to later convert a galvanized container into a sandwich panel?
Technically, this is possible, but it is not economically justified at all. Because the chassis and structure of panel containers are different, and the cost of opening the sheets, installing the panels, and throwing away the materials is much more expensive than buying a new sandwich panel container. Therefore, it is better to have a detailed needs assessment from the beginning.
