Why File Cabinets Are Metal

Metal file cabinets are ubiquitous in offices and organizations around the world. But have you ever wondered why these storage furniture pieces are made of metal rather than other materials? There are some practical reasons why metal has become the standard material for filing cabinets over the years.

Durability of Metal File Cabinets

One of the biggest advantages of metal filing cabinets is their durability. Metal is very sturdy and stands up well to heavy use and abuse. File cabinets often have to hold a lot of weight from stacks of files and paperwork. Lesser materials like plastic or particle board could buckle or warp under the weight.

Metal file cabinet frames are rigid and withstand daily opening and closing of drawers. The slidable hanging file folders and shelf folders inside put a lot of sliding friction on the drawer glides over years of use. Metal-on-metal glides are self-lubricating and hold up better than plastic or wood rails.

Steel filing cabinets are hard to dent and retain their right-angle shapes despite bumps and impacts from office equipment, employees, etc. A quality metal cabinet can last for decades of daily use and still look great.

Fire Resistance of Metal File Cabinets

Another reason metal has become the standard is because steel filing cabinets are naturally fire resistant. Important paper documents can suffer destruction or damage in a fire if not adequately protected.

Metal file cabinets are built with steel exterior walls and drawers that protect the internal contents from fire for a period of time. This gives people more opportunity to rescue important files and records if a fire breaks out in the building.

Most file cabinets are subjected to fire resistance testing to verify their rating, such as Class B for 2 hours or Class C for 1 hour. This classification means the cabinet can withstand extreme heat and resist the spread of internal flames for the designated time.

Corrosion Resistance with Painted Metal

Bare steel has the tendency to corrode from moisture in the air over time. So quality file cabinets are always coated with paint, enamel, or powder coating to seal and protect the steel. This also gives the cabinets a more attractive and professional finish.

The sealed metal surface resists corrosion, bubbling, and peeling even with heavy everyday use over many years. Durable baked-on paint finishes retain their original look despite spills, stains, or light impacts.

Given humid office environments and accidental spills of liquids on cabinets, the water-resistant finish is important. Unprotected bare metal would gradually rust, stain, and degrade from routine exposure to moisture.

Strength and Security of Locking Drawers

File cabinets often contain confidential documents, valuables, money, and other items that necessitate secure locking drawers. Sheet metal panels and frames allow heavy-duty slide lock bars to be welded inside each drawer.

A steel locking file cabinet provides strong and reliable security for the contents inside. Forced entry is difficult for thieves without leaving obvious signs of damage. The heavy-gauge metal and welded internals give far better protection than lightweight materials.

Important files stay physically secure and protected within a quality locked metal cabinet even in shared offices. This deters opportunistic thieves and prying eyes from illegally accessing private information.

Variety of Sizes Meet Any Need

Metal allows filing cabinets to be constructed in a wide array of sizes, configurations, and capacities. Offices can find metal file cabinets sized precisely for any space and filing requirement:

• 2-drawer – Standard two drawer vertical filing cabinets offer a simple and popular storage solution for small offices. This size is easy to move and fits well in closets, against walls, in corners, etc. The drawers provide ample space for folders without occupying too much floor space.
• 4-drawer – Larger four drawer filing cabinets provide abundant storage space while minimizing the floor space needed. These are ideal for frequently accessed files since all contents are within easy reach. The top two drawers provide standing access while the bottom drawers require slight bending or kneeling.
• 5-drawer – For major filing needs, five drawer upright cabinets maximize storage in a minimum footprint. These can hold entire office or departmental files in a single cabinet conveniently located in a central place. The five graduated drawer sizes efficiently hold everything from small folders to large binders and big hanging folders.
• Lateral – Lateral filing cabinets are designed to sit under windows and against walls. By orienting drawers front-to-back rather than up-and-down, laterals maximize floorspace usage. The shallow but wide drawers can hold mass quantities of hanging folders and files.
• Wide format – For oversize plans, maps, artwork, and other large format documents, wide format file cabinets are essential. These specialty models have extra wide and deep drawers to flat-file these materials neatly rather than rolling them up.

Ease of Mobility

Metal file cabinets are designed for mobility to allow flexible placement anywhere needed. Ball-bearing drawer glides give effortless opening and closing of drawers even when heavily loaded. Keys allow instant locking of every drawer to secure contents while rolling cabinets around.

Locking casters are easily mounted to the bottom of many file cabinets. With the wheels engaged, heavy multi-drawer cabinets can be steered around tight corners and moved between rooms by a single person. The casters also level and stabilize the cabinets on uneven floors.

Long Lifespan Saves Money

The durability and longevity of metal filing cabinets actually saves money in the long run. More fragile wood or plastic cabinets would need frequent replacing – maybe every 5 years or so. But sturdy steel filing cabinets can serve 20 to 30 years or more with proper maintenance.

Over the decades, companies realize major cost savings by purchasing high quality metal cabinets compared to cheaper units. And because steel is readily recycled, old file cabinets can be sustainably recycled when their lifespan is finally reached.

Flexible Styling Options

Beyond basic black or putty colors, metal file cabinets are actually available in a wide palette of color and finish options:

• Custom paint colors – Most filing cabinet companies offer custom color matching to any Pantone or RAL color for a consistent office décor. Special finishes like high gloss are also available.
• Laminates – Metal filing cabinets can be laminated in wood grains, patterns, or solid colors for an upscale executive look. Durable laminates withstand heavy office use for many years.
• Veneers – Real wood veneers like oak, cherry, and maple applied to steel cabinets provide a premium furniture look. Sealed veneers maintain their rich warmth for the life of the cabinet.
• Powder coating – For extreme durability in any color, powder coated finishes are baked onto cabinets for office customization. This uniform covering resists wear, fading, and everyday abrasion.

Why Paper Files Still Matter in the Digital Age

With computers and cloud data storage dominating modern offices, you may wonder why traditional physical file cabinets are still used. While technology has certainly enabled organizations to go paperless, there are good reasons to retain paper documents:

• Redundancy – Paper files provide a second copy if digital files are damaged, hacked, or corrupted. Important documents preserved on paper are accessible if technology fails.
• Permanence – Digital data may be vulnerable as technology changes so rapidly. But paper documents filed in cabinets will remain accessible and readable for decades.
• Convenience – Reading lengthy documents on paper can be easier on the eyes than on screens. Paper handouts in meetings allow better engagement.
• Security – Despite cybersecurity advances, digital data is still vulnerable to hacking and theft. Sensitive paper files locked in cabinets are more secure.
• Legal – Vital records such as property deeds and stock certificates often must be retained in original paper form to comply with tax and legal requirements.
• Familiarity – Despite the digital revolution, many executives and employees still prefer the traditional workflow of paper documents rather than screens. Well organized paper records support this workstyle.

For these reasons, filing cabinets likely will continue serving offices even alongside advanced virtual data storage. Metal cabinets provide the most secure and durable repositories for vital paper records in almost any industry or organization. The metal construction ensures fire resistance, corrosion resistance, and protection of contents for many decades if properly cared for.

History of Metal File Cabinet Development

The origins of today’s familiar metal filing cabinets trace back to the late 19th century as businesses sought to organize their growing piles of paper records and documents. Here are some key developments in metal file cabinet history:

• 1870s – Pigeonhole cabinets were introduced, made of wood with compartmentalized document storage. Sliding drawers soon replaced stationary pigeonholes for easier access.
• 1880s – Metal cabinets emerged, with primitive drawer slides and early lock designs. Rotary cabinets on rotating bases became popular to conveniently swing around in offices.
• 1920s – Improved ball bearing slides enabled easy opening and closing of heavy drawers. Smooth steel drawer suspensions and centralized locking bars led to wide adoption.
• 1930s – Four-drawer vertical file cabinets became standard for high-capacity storage paired with a small footprint. Mature engineering gave reliably smooth operation.
• 1940s – Lateral files gained favor for under-window and against-wall locations where vertical cabinets couldn’t fit. Smooth and secure roll-out drawers provided ample side-to-side storage.
• 1950s – Insulated fire resistant file cabinets were introduced to protect paper documents. Rigid welded steel handles extreme heat for a defined fire rating. Centralized locking and label holders were added.
• 1960s – Color finishes like Sandstone, Desert Sand, and Misty Gray became available beyond traditional black and tan. But office decor was still limited to neutral earth tones.
• 1970s – More vibrant and varied colors emerged such as bright red, orange, green, and blue filing cabinets to match the mod era. But staid office culture quickly reverted back to conservative coloring.
• 1980s – The digital age began with computers for data processing and word processing. But continued reliance on paper filing and recordkeeping kept cabinets prevalent.
• 1990s – Ergonomic assisted opening features were developed, allowing easy opening of heavy deep drawers with minimal physical effort. Electrically height-adjustable desks further reduced strain.
• 2000s – Anti-tip provisions, pinch point protections, and child safety features were added to filing cabinets to meet evolving safety standards. Centralized locking remained standard for security,

Today metal filing cabinets remain a staple of the office landscape for their proven durability, security, fire protection, economy, and sustainability. Modern models have enhanced mobility, expanded digital age color choices, and user-friendly designs. But the core all-steel construction provides the same reliable and protective filing function that has served businesses well for over a century.

Key Factors in Selecting Metal File Cabinets

With the wide range of filing cabinets on the market, here are the key factors to consider for your specific needs:

Intended use – Will the cabinet be for general office filing, archival records storage, automotive shop parts, medical office patient files, legal firm case files, or other uses? Specialty filing solutions may suit certain applications better than ordinary office filing cabinets.

File sizes – Standard letter and legal size files need different proportions than large engineering drawings, oversize medical films, hanging folders, or index card collections. Measure your actual materials to size the drawers appropriately.

Capacity – Look at current and future filing amounts and determine the ideal number of drawers and overall cabinet size. Remember to allow room for future expansion.

Footprint dimensions – Check the available floorspace for the cabinet’s footprint and confirm the cabinet size will fit. Measure doors and hallways to ensure the cabinet can be moved in and out.

Locking requirements – Determine whether secure drawer locking is needed or if unlocking drawers will suffice. Key management for multiple cabinets should also be considered.

Mobility needs – Will the cabinet stay stationary or need to be moved occasionally? Caster wheels make heavy cabinets easy to relocate. But casters raise overall height so measure room clearances.

Fire rating – If fire resistance is important for the contents, look for a cabinet meeting UL, ETL, or other standards. Typical ratings are 1 or 2 hours for Class B and C.

Accessibility – Be sure the drawer configuration allows users of different heights to reach contents, especially in bottom drawers. Front-to-back rails help pull heavy deep drawers out fully.

Appearance – Select a color, laminate, or wood veneer fitting your office décor. Also look for cabinet lines with attractive drawer front styling if they will be publicly visible.

Budget – Prices range from under $200 for basic models to over $2000 for premium cabinets. Determine how much to reasonably invest for your needs and desired quality.

Once you evaluate these factors, a metal filing cabinet well matched to your requirements will provide many years of reliable and protective document storage. Take time to consider different models and check reviews to get the ideal filing solution.

Maintaining Metal File Cabinets

To keep your filing cabinets functioning smoothly and securely for decades, follow these metal file cabinet maintenance tips:

• Use a duster to regularly remove dust, which can build up on cabinet tops and exterior surfaces over time. Dust the drawers around the slides and rails.
• Wipe down the cabinet exteriors periodically with a mild all-purpose cleaner and microfiber cloth to keep the finish looking freshly polished. Avoid harsh chemicals or abrasives.
• Every few months, disassemble each drawer by unclipping the slides. Fully extend the slides, clean them and lubricate them with a silicone spray. Reinstall them evenly.
• Every 2-3 years, assess if drawer glides or slides need replacement. Look for signs of wear like sagging, unevenness, jamming, or grinding and replace any deteriorated slides.
• Evaluate drawer locks and keys yearly and replace any malfunctioning locking mechanisms, missing keys, or damaged lock bars. Proper locking protects contents security.
• Touch up scuffed or scratched paint with matching color enamel paint. Bare metal exposed to air can corrosion so keep the finishes intact.
• Periodically assess for dents, bends, warped metal, or rust, which can compromise sturdiness. Refinish or replace cabinets with severe damage.
• Avoid overloading drawers which strains the glides and can cause breakdowns or tipping. Heavy contents are also harder to pull out. Remove unneeded files yearly.
• Position cabinets away from direct heat sources like radiators, vents, or windows with strong sunlight exposure which can damage finishes.

With regular maintenance like dusting, cleaning, lubricating, and inspecting, quality metal filing cabinets should serve your business reliably for 20-30 years or more before needing replacement. Proper care protects your investment in durable storage.

Innovations in Modern Metal File Cabinets

While traditional all-metal construction remains standard, modern filing cabinets include helpful new features for today’s office needs:

• Anti-tip technology – Smart counterbalances and interlocking mechanisms prevent cabinets from tipping over even when heavily loaded top drawers are extended.
• ADA compliance – Lower and upper reach limits for drawer access meet Americans with Disabilities Act regulations. ADA cabinets ensure equal accessibility.
• Lock options – Alongside traditional key locks, electronic RFID card access, combination keypads, and biometric fingerprint scanning provide enhanced security and tracking of access.
• Follow-me rails – Full extension rails allow very deep drawers to be pulled out more for complete back-of-drawer access without tipping risk. Smooth ball-bearing operation prevents jams even when fully extended.
• Assisted opening – Hydraulic or spring technologies reduce the effort needed to open heavily loaded bottom drawers that would otherwise resist motion or slam shut.
• Centralized locking – Single control locks save time by locking all drawers instead of individual keyed locks. Some systems also regulate user access to different drawers.
• Built-in chargers – For mobile device convenience, some cabinets offer pop-up charging cables or USB ports to charge phones and tablets from inside drawers or on tops.
• Casters & levelers – Heavy duty wheels with 360° rolling allow easy repositioning. Built-in levelers stabilize cabinets on uneven floors and fine-tune alignment after moving.
• Eco-friendly materials – Components made of recycled steel, wood from sustainably managed forests, and plant-based sound-dampening materials satisfy LEED green building standards.

These innovations keep metal file cabinets highly functional and user friendly for 21st century workplaces while still retaining the core benefits of durable steel construction.

Fireproofing for File Cabinets

Fireproof filing cabinets provide vital protection for irreplaceable paper documents. Built with heavy-gauge steel and special insulation, fireproof cabinets can withstand high temperatures for prolonged periods and prevent contents from combusting.

Here are key ways metal filing cabinets are engineered to be fire resistant:

• All-welded steel bodies, drawers, and frames avoid vulnerable fasteners that can melt apart. Insulated double-walled drawers prevent outside heat from penetrating.
• High density fire-resistant insulation like calcium silicate or gypsum boards fills interior panels surrounding drawers to absorb and dissipate heat.
• Integrated air pockets and chambers provide additional thermal buffer zones to keep interiors below paper ignition temperature.
• Full-extension or telescoping slides allow full access to back of deep drawers. Built-in mechanisms re-close drawers automatically for fire protection if left open.
• Dual acting seals expand in intense heat to seal any gaps along the drawer openings that could admit flames.
• Locking mechanisms keep drawers securely closed to prevent oxygen from feeding fires inside the drawers. Insulated lock bolts avoid malfunction.
• Gaskets, barriers, and subdividers segment each drawer into separate insulated compartments forming protective layers between folders.
• High performance exterior paint finishes rated for high heat exposure maintain cabinet body integrity rather than blistering, peeling, or outgassing toxins.

Independent testing laboratories verify fire ratings by subjecting cabinets to furnace-like temperatures and assessing damage afterwards. Common ratings are 1 or 2 hour Class B and 1 hour Class C.

Choosing a Fireproof File Cabinet

If your documents require fire protection, look for cabinets certified by UL, ETL, or another recognized laboratory.
