The advantages of stainless steel IBC containers compared to plastic IBCs
Intermediate bulk containers (IBCs) are indispensable in logistics and warehousing, especially for the transport and storage of liquids, chemicals and bulk goods. Companies are often faced with the question: should we procure IBCs made of stainless steel or plastic? While both variants have their advantages, stainless steel IBCs offer decisive benefits in many applications. In this blog post, we shed light on why stainless steel IBC containers may be the better choice for many companies in 2024.
1. Greater Robustness and Durability
Stainless steel IBCs, mostly made from V2A (1.4301), are renowned for their extraordinary stability and resilience. They are:
- Corrosion-resistant: Stainless steel withstands extreme conditions, including moisture, acids, and alkalis, without rusting. This makes it ideal for storing aggressive chemicals, solvents, and many other substances. For particularly aggressive products, stainless steel IBC containers in high-alloy V4A versions (e.g., 1.4404 or 1.4571) are available.
- Mechanically robust: Compared to plastic, stainless steel is significantly more resistant to physical stress, such as impacts, pressure, or mechanical loads. This is a major advantage, especially with frequent use of IBC containers, as handling with forklifts can quickly cause dents and damage.
- Long-lasting: While plastic IBCs (primarily made from HDPE) degrade over time due to UV exposure, chemical reactions, or physical wear, stainless steel IBCs maintain their quality properties for many years.
2. Higher Hygiene Standards and Easy Cleaning
Stainless steel IBCs are particularly popular in the food, pharmaceutical, and cosmetics industries, where hygiene is a top priority:
- Pore-free surface: Stainless steel has a very low surface roughness, making the accumulation of microorganisms, dirt, or residues almost impossible.
- Easy to clean: Stainless steel IBCs can be easily cleaned with steam, sterilized, or washed with strong cleaning agents—without damaging the stainless steel surface in contact with the product.
- Odor-neutral: Unlike plastic (HDPE), stainless steel does not absorb or release odors or flavors to the stored substance.
3. Environmental Friendliness and Sustainability
In an era where sustainability is a critical factor, stainless steel IBCs outperform plastic alternatives:
- Extended lifespan: The high durability of stainless steel IBCs means fewer resources are required to manufacture new containers. The frame, often made of galvanized steel, can be replaced if damaged, maximizing the lifespan of the stainless steel IBC.
- Used stainless steel IBCs: To reduce high acquisition costs, high-quality used stainless steel IBC containers can be purchased from specialized dealers at significantly lower prices. The quality of a used stainless steel IBC is often nearly identical to a new one.
- Recyclability: Stainless steel is 100% recyclable without losing quality. At the end of their service life, stainless steel IBCs can be melted down and repurposed into new products.
4. Safety and Content Protection
Stainless steel IBCs provide exceptional protection for storing and transporting environmentally hazardous or sensitive media and hazardous materials:
- High-temperature resistance: Stainless steel withstands extreme temperatures, whether in very cold or hot conditions.
- Chemical neutrality: Unlike plastic, stainless steel does not release plasticizers or other chemicals into the content. This is particularly important for sensitive products such as pharmaceuticals, as well as food items like liquid eggs or fruit preparations.
- Flame resistance: Stainless steel is non-flammable, reducing risks during the storage and transport of flammable substances.
5. Long-term Cost-effectiveness
Although stainless steel IBCs are more expensive to purchase than plastic IBCs, this drawback is offset by their durability and versatility:
- Lower maintenance costs: Their robustness and corrosion resistance significantly reduce repair and replacement costs.
- Reusability: Stainless steel IBCs are designed for multiple uses and remain functional even after numerous cycles.
- Value retention: Stainless steel retains a high residual value as a raw material. Additionally, stainless steel IBCs can be resold to dealers in used condition at a stable value.
When Are Plastic IBCs the Better Choice?
Despite the numerous advantages of stainless steel IBCs, there are situations where plastic IBCs are more suitable:
- For short-term or single-use applications, as they are more cost-effective to purchase.
- When weight is a critical factor, as plastic IBCs are significantly lighter.
Conclusion
Reusable stainless steel IBC containers offer numerous advantages, especially in terms of durability, hygiene, and sustainability. They are the ideal choice for demanding applications in the chemical, food, and pharmaceutical industries.
Good to know: On average, an investment in a stainless steel IBC pays off after less than two years of use (ten cycles), assuming five IBC rotations per year. This was the conclusion of an independent study published by the IBC manufacturer Thielmann in 2021.
The high initial investment in a stainless steel IBC can be discouraging for some users. In such cases, purchasing a certified used stainless steel IBC container is a practical option. A used stainless steel IBC is immediately available and offers an excellent cost-effective and sustainable alternative to a new stainless steel IBC container.
By investing in stainless steel IBCs, you can choose a future-proof solution that meets the high demands of modern industrial applications.
