Why is the use of sandwich panels mandatory in the construction of industrial sheds and cold stores?
The end of the era of traditional materials in large projects
In the modern world of engineering and construction, time and energy are two determining factors in the economic success or failure of a project. Until a few decades ago, the construction of industrial sheds and cold stores was carried out using traditional materials such as bricks, cement or single-layer metal sheets. These methods not only prolonged the construction process by months, but also greatly increased maintenance costs due to the severe waste of energy.
Today, expert engineers and contractors know very well that the use of sandwich panels is no longer a "luxury choice", but rather a "definite and engineering requirement". But what technical and economic characteristics have made sandwich panels the undisputed standard for the construction of sheds and cold stores? In this specialized article from Sabat Sanat Factory, we will examine this issue in detail and scientifically.
Sandwich Panel; A Masterpiece of Material Engineering
Before we get into the reasons for this requirement, it is better to understand the structure of this product. Sandwich panel is a three-layer integrated structure; just like a sandwich, two outer layers are made of resistant steel sheets (galvanized, aluzinc or aluminum) and in their central core, a very powerful insulator (usually polyurethane foam) is injected. The combination of these three layers creates a material that is simultaneously light, extremely resistant and absolutely insulating.
Vital reasons for using sandwich panels in cold stores
Constructing a cold store (below zero or above zero) is one of the most sensitive construction projects. The smallest temperature fluctuation can lead to the spoilage of hundreds of tons of food or medicine and, as a result, irreparable financial losses.
1. Maintaining an unrivaled cooling chain and thermal insulation
The most important task of a cold store is to maintain low temperatures with the lowest possible compressor operation. The polyurethane core in cold storage sandwich panels (which are usually 10 to 15 centimeters thick or more) has the lowest heat transfer coefficient of all building materials. This powerful insulation prevents cold loss and reduces the electricity consumption of refrigeration systems by up to 70%.
2. Complete insulation and prevention of thermal bridges
The edges of cold storage sandwich panels are designed in the form of a tongue and groove (male and female). This design allows the panels to be locked together so that there are no seams or gaps for air to pass through. This precise locking prevents the creation of "thermal bridges" and frost on the interior walls of the cold storage.
3. Compliance with the strictest health and safety standards (HSE)
The cold storage environment must be completely isolated and washable. The colored galvanized sheets used on the surface of the sandwich panels create a completely smooth and antibacterial surface. These surfaces are easily washed, resistant to detergents and do not allow the growth of any fungus or mold, which is required to obtain health permits from the Food and Drug Administration.
Why is it not justified to build industrial sheds without sandwich panels?
Industrial sheds, manufacturing plants, logistics warehouses and aircraft hangars have different requirements than cold storage, but the use of wall and ceiling sandwich panels in them is equally essential:
1. Rapid return on investment with stunning implementation speed
In industrial projects, “time” equals “money”. Installing traditional materials requires months of time, scaffolding and numerous manpower. But sandwich panels are shipped to the project site prefabricated and with precise dimensions. A professional installation team can install hundreds of square meters of panels per day. This means that your shed will reach the exploitation and profitability stage months earlier.
2. Reduction of dead weight of the structure and earthquake resistance
Sandwich panels are surprisingly light (about 15 to 20 kilograms per square meter). This lightness greatly reduces the dead load imposed on the metal frame and foundation of the shed. As a result, the structural designer can use lighter steel sections, which means a significant reduction in the cost of purchasing hardware. Also, lighter structures perform safer during an earthquake.
3. Fire resistance (non-combustible and slow-burning)
There is always a risk of fire in industrial environments. The foams used in standard sandwich panels (such as PIR foam) have flame retardant (B2) or fireproof (B1) properties. These panels do not ignite in the event of a fire and do not contribute to the spread of fire; an important feature that is vital for obtaining fire approvals and insuring industrial sheds.
Sabat Sanat; Quality and engineering assurance in sandwich panel supply
Procuring sandwich panels from intermediaries or workshops lacking technology is a big risk for your billion-dollar projects. Sabat Sanat Company in Mazandaran, with its completely factory infrastructure, brings the following advantages to your projects:
- Standard transportation and handling: The use of equipped overhead cranes in the Sabat Sanat factory prevents any warping, microcracks or damage to the structure of the panels during loading.
- Consulting and Value Engineering: Our engineering team analyzes your project needs before production and optimizes the foam thickness and sheet type based on climate and application (subzero cold storage, dry storage, etc.) to avoid additional costs.
If you are planning to build a modern industrial warehouse or set up a standard cold storage, the choice of primary materials is a fateful decision. Using sandwich panels is not only a technical requirement, but also the smartest investment to reduce the long-term costs of your project.
