File cabinets are essential pieces of office furniture used to store important documents and records securely. The most common types of file cabinets are lateral file cabinets, vertical file cabinets, and fireproof file cabinets. The metal used to construct file cabinets can vary, but steel is the most popular choice for its durability, fire resistance, and security.
Why Steel is Preferred for Making File Cabinets
Steel is the ideal metal for manufacturing file cabinets because of the following reasons:
- Strength and Durability – Steel is incredibly strong and durable. File cabinets made of steel can withstand frequent opening and closing of drawers, providing years of reliable performance. The sturdy steel construction prevents warping, bending, or denting under heavy use.
- Fire and Heat Resistance – Steel has excellent fire and heat resistant properties. In the event of a fire, steel file cabinets are designed to withstand high temperatures and protect documents inside. This makes steel file cabinets a safer choice, especially for important records and files.
- Security – Steel is difficult to break or cut through, making steel file cabinets highly secure. The locks and drawers are designed to prevent unauthorized access to the contents inside. This security makes steel file cabinets ideal for sensitive documents.
- Weight – Steel has hefty weight which provides stability and prevents file cabinets from tipping over easily. The weight also enhances durability and sturdiness.
- Rust Resistance – Steel used for file cabinets is often galvanized or coated to prevent rusting, corrosion, and degradation over time. This allows steel file cabinets to perform optimally even in wet or humid environments.
Steel Grades and Types Used in File Cabinet Manufacturing
Not all steel is created equal when it comes to file cabinets. The most common grades and types of steel used are:
Cold-Rolled Steel
This involves steel coils that are processed and rolled at normal temperatures to improve strength and precision. Cold-rolled steel has an attractive smooth finish and accurate dimensions, making it ideal for file cabinet construction.
Hot-Rolled Steel
Steel that is rolled at high temperatures to soften and shape it effectively. Hot-rolled steel is stronger than cold-rolled variants. Sturdy file cabinets can be crafted from thick hot-rolled steel.
Galvanized Steel
Steel sheets that are coated with a layer of zinc to provide superior rust and corrosion resistance. Galvanized steel offers excellent longevity for file cabinets.
Stainless Steel
Steel alloy containing chromium and nickel to drastically boost corrosion resistance, even in wet conditions. Stainless steel provides impressive durability for file cabinets.
Steel Plate
Thick solid steel sheets with precise tolerance. Steel plate allows heavy-duty file cabinets to be fabricated for holding very large volumes of documents and records.
Key Properties of Steel for File Cabinets
The most sought-after properties of steel used in the manufacturing of file cabinets include:
- High tensile and yield strength – Prevents warping or deforming under load
- Formability – Can be bent and folded into cabinets easily
- Weldability – Steel sheets can be welded together neatly
- Dimensional stability – Precision and squareness for smooth drawer opening
- Impact resistance – Dents and damage resistant
- Abrasion resistance – Withstands wear and tear over time
Other Metals Used for Specialty File Cabinets
While steel is the clear choice for most file cabinet applications, other metals are sometimes used for specialty cabinets:
Aluminum
Much lighter than steel but also less resistant to fire and impacts. Used for lightweight portable file cabinets.
Stainless Steel
For the ultimate in corrosion resistance for extremely wet and corrosive environments. More expensive than regular steel.
Iron
Cheaper alternative to steel but prone to corrosion. Usually found in older vintage-style file cabinets.
Sheet Metal
Thin sheets of metal alloys used mainly for covering and camouflaging the exterior of file cabinets but not the primary structural material.
Key Takeaways on Metals for File Cabinets
- Steel is the prime choice of metal for file cabinet manufacturing, owing to its durability, security, fire resistance, and stability.
- Cold-rolled steel and hot-rolled steel are commonly used, along with galvanized and stainless steel. Steel plate provides the most rugged construction.
- Desired properties of steel include high strength, formability, weldability, impact resistance and dimensional stability.
- Other niche metals like aluminum and iron may be used but are less common than industry-standard steel.
- The right metal ensures file cabinets stand the test of time while securely protecting vital records and documents.
Frequently Asked Questions
What type of steel is best for file cabinets?
Cold-rolled steel and galvanized steel offer the best combination of strength, durability and corrosion resistance for long-lasting file cabinets. Hot-rolled steel also provides superb sturdiness.
Are wood or plastic file cabinets as secure as steel?
Generally not. Wood and plastics are easier to break into than steel. The strength and security of steel file cabinets is superior for protecting confidential contents.
Does thicker steel make better file cabinets?
Yes, thicker steel provides enhanced sturdiness and weight for stability. But too thick can make the cabinets overly heavy. Optimal steel gauge thickness is between 18 to 22 gauge.
Why shouldn’t you use a torch on a steel file cabinet?
The intense heat can damage the temper of the steel and weaken it. A torch burns through the fire-protective coating. This can reduce the fire rating and compromise the integrity of the cabinet.
Do all steel file cabinets offer fire protection?
Not necessarily. Only cabinets rated for fire protection are designed to withstand high temperatures. Fireproof or fire-resistant labels indicate the level of protection provided.
Conclusion
Steel is the undisputed choice when it comes to constructing durable, secure, and fire-safe file cabinets. Not only is steel strong and stable, but it also offers vital protections for sensitive paperwork and records. With options such as cold-rolled steel, hot-rolled steel, galvanized steel and steel plate, manufacturers can fabricate high-performance file cabinets suited for a wide range of demanding office environments. The correct selection and use of steel ultimately results in reliable file cabinets able to serve their purpose for many years while keeping contents organized and safe.
