FAQ: Frequently asked questions about our metal filing cabinets

When should a filing cabinet be lockable?

A lockable filing cabinet is an essential component in any office environment where security and data protection play a central role. The need for a lockable filing cabinet is essential, especially in situations where confidential or sensitive documents and records need to be stored. Below are specific scenarios and reasons why and when a filing cabinet should be lockable:

1. Confidential documents:

If your office works with confidential information that is not intended to be accessible to the public or even to all employees, a lockable metal office cabinet provides the security necessary to protect these documents from unauthorized access.

2. Sensitive documents:

Sensitive documents, such as personnel files, financial reports or contractual documents, often contain information that could cause harm if disclosed. A lockable filing cabinet effectively secures these documents.

3. Authorities and legal requirements:

In many cases, government regulations and data protection laws explicitly require the secure storage of personal data or other sensitive information. For authorities, lawyers, tax consultants and similar professional groups, a lockable filing cabinet is not just a recommendation, but a necessity.

4. Protection against unauthorized access:

Regardless of the type of documents, a lockable filing cabinet provides an additional layer of security against theft, espionage, or accidental viewing by unauthorized parties. This is particularly relevant in office environments where many people have access.

5. Data protection and compliance:

Now more than ever, companies are required to protect personal data and information in accordance with the General Data Protection Regulation (GDPR) and other local data protection laws. A lockable cabinet helps meet these needs by providing a physical protection mechanism against potential data breaches.

6. Ensuring security:

In addition to protecting against unauthorized access, lockable filing cabinets also play a role in a company's overall security strategy. They help create a safe work environment where employees and customers alike can be confident that sensitive information is protected.

In any context where privacy and information security are a priority, investing in a quality, lockable filing cabinet is a wise decision. It's not just about meeting regulatory requirements, but also about the trust and security you offer your employees, customers and partners.

Choosing the right size metal filing cabinet depends on a variety of factors, including the space available in your office, the amount of documents and folders to be stored, and your specific document organization and accessibility needs. To find the perfect filing cabinet for your needs, you should consider the following aspects:

1. Determine the required capacity:

Think about how many folders and documents you need to keep. The default folder height serves as a good basis for calculating the space required. An average folder requires about 7.5 cm width on the shelf. Plan additional space for future documents to avoid running out of space again in the short term.

2. Measurement of available space:

Before choosing a filing cabinet, accurately measure the area where the cabinet will sit. Consider the height, width and depth of the available space. Make sure there is enough room to open doors (particularly with hinged doors) or pull out drawers without obstructing the flow of traffic in the room.

3. Understanding standard filing cabinet dimensions:

Metal filing cabinets come in various standard sizes. The height usually varies between 100 cm (for smaller models) and 195 cm (for larger models). The width often ranges from 80 cm to 120 cm, while the depth can be between 40 cm and 45 cm. These dimensions are crucial to ensure that the cabinet will both fit your space and provide enough storage space.

4. Consideration of room size and layout:

The size of the room and the general layout of the office play an important role in deciding the size of the filing cabinet. In smaller offices, tall, narrow cabinets could save space, while in larger offices, wider models with multiple shelves may be more practical.

5. Folder height adjustment:

Most filing cabinets are designed to accommodate standard file folders, the spines of which are typically about 12 inches high. Make sure that the shelves in the cabinet are adjustable so that different folder heights and document formats can be flexibly accommodated.

6. Check dimensions:

Before purchasing, make sure the specified dimensions of the filing cabinet meet your needs. Pay particular attention to the interior dimensions to ensure the storage space meets your needs.

By following these steps, you can ensure that you find a metal filing cabinet that will both fit into your space and provide enough space to safely store your important documents and folders.

The number of folders that fit in a metal filing cabinet depends on several factors, including the dimensions of the cabinet itself, the folder height, and how the shelves are arranged in the cabinet.

1. Folder dimensions:

A standard file folder is about 7.5 cm wide. This is an important factor because the width of the folders determines how many can fit next to each other on a shelf.

2. Shelves and available storage space:

The number and adjustability of the shelves determine how the space in the closet can be used. Many filing cabinets offer adjustable shelves so you can adjust the space between the shelves to fit the size of your files.

Factors that can affect capacity:

  • Space requirements: This number can vary depending on the actual thickness of the folders set and the space required for comfortable loading and unloading of the folders.

  • Storage: If documents or smaller items are to be stored in the cabinet in addition to the folders, this will reduce the folder capacity accordingly.

  • Interior design: Some filing cabinets offer specialized storage solutions, such as hanging files, that use the available space differently.

To determine the exact capacity of a filing cabinet for your specific files and needs, it is important to know the interior dimensions of the cabinet and how flexibly the shelves can be arranged. It is always advisable to plan some extra space to avoid overcrowding and make folders easier to access.

Metal filing cabinets offer many advantages in terms of durability and safety, but when it comes to the specific aspect of fire resistance, it is important to differentiate between general metal cabinets and specially designed fireproof safety cabinets.

General metal filing cabinets:

While standard metal filing cabinets are sturdy and can provide some protection from external influences, they are usually not fireproof in the true sense. Metal can conduct heat, which means that in the event of a fire, the internal temperature of the cabinet can rise quickly. This can result in the documents and materials stored inside being at risk, even if the outer casing of the cabinet is not directly damaged by fire.

Fireproof safety cabinets:

For real protection against fire, special fireproof safety cabinets are required. These cabinets are specifically designed to protect the contents from high temperatures and fire. You have:

  • Insulating materials: Fireproof cabinets are equipped with special insulating materials that can slow down heat transfer and maintain the internal temperature at a safe level for a certain period of time.

  • Seals: To maximize protection, these cabinets are often equipped with heat-resistant seals that swell when exposed to heat, further preventing heat and smoke from entering the cabinet.

Choosing the right cabinet:

If you need to store documents or materials to be protected in the event of a fire, it is important to invest in a dedicated fireproof safety cabinet. When purchasing, you should pay attention to the specific ratings and certifications that indicate the duration (e.g. 30 minutes, 1 hour, 2 hours) at which temperatures the cabinet can effectively protect the contents.

So, in summary, not all metal filing cabinets are fireproof. For true fire protection, consider specially designed fireproof safety cabinets that are designed to protect your valuable documents and items even in extreme conditions.
