Choosing Operational Cabinets and Lockers: Types, Load Capacity and Standards at a Glance

Hinged-door cabinet, sliding-door cabinet, compartment cabinet, or a locker cabinet with plinth – anyone furnishing a workshop, warehouse, or changing room quickly runs into a confusing range of cabinet types. Manufacturers such as PAVOY from Hillesheim, Germany, specialising in steel furniture for industry since 1946, offer a dozen cabinet variants on their own. The type name, however, says little about what really matters: how much may go inside, which standard applies, and how to recognise solid construction.

This guide sorts the common cabinet and locker types, explains which standards govern load capacity and safety, and uses concrete examples from the range of cabinets and storage furniture to show what matters in material thickness, locking systems, and upkeep. PAVOY products serve as examples here, not as advertising – the criteria described apply to steel cabinets from any manufacturer.

Cabinet types at a glance: which type suits which purpose?

Cabinet type names primarily describe the door construction – but that has real consequences for space requirements, access, and intended use:

Compartment cabinets and locker cabinets are frequently confused: in a compartment cabinet, each compartment is a separate, usually equally sized storage unit without a clothes rail. In a locker cabinet, several compartments are stacked into one narrow column – practical when many people need to lock something away briefly, such as phones or valuables before a shift.

Load capacity: what actually matters on the data sheet

Several figures circulate for cabinets that are easily confused. A look at real product data shows the difference:

• Shelf load – the weight a single shelf carries. For a sliding-door modular cabinet for sports equipment, for example, this is 80 kg per height-adjustable ball shelf.
• Maximum total load – the sum across all shelves of a cabinet. For the same cabinet this is 600 kg across four shelves – not 4 × 80 kg, because the carcass and side panels set the actual limit.
• Load capacity of the whole unit – for workbenches with a base cabinet, a combined total load is often stated, for instance up to 2,000 kg for PAVOY workbenches with a beech multiplex worktop.

The same rule from racking design applies here by analogy: shelf load and total load are two separate limits that must both be observed. How this works in detail for storage racking is explained in more depth in the guide on shelf load and bay load – the same logic carries over to cabinets, even though there is no DGUV requirement for a load notice as with forklift-served racking.

In practice this means: anyone looking for a cabinet for heavy test equipment or engine parts should not just look at the largest advertised figure, but at the shelf load of the level actually needed. A cabinet with a high total load but thin, poorly supported shelves does not help if the heaviest item has to go on a single shelf.

Material thickness as an indicator

The thickness of the steel sheet is not an official standard value, but in practice it correlates with torsional rigidity and longevity. Simple office or filing cabinets often use thinner sheet; workshop and industrial cabinets rely on more robust carcasses, reinforced door rebates, and welded rather than merely bolted shelves. One indicator of later stability: if shelves can be adjusted on a continuous hole grid (for example a 17 mm grid on PAVOY cabinets) and carry a load without visible sagging, the construction is designed for its intended purpose.

Standards and test marks: how quality can be objectively assessed

Unlike storage racking, for which DGUV Information 208-061 provides a very detailed set of rules, operational cabinets are covered by several, partly older standards:

• DIN EN 16121 – requirements for safety, strength, durability, and stability of non-domestic storage furniture, which also covers office and operational cabinets.
• DIN EN 16122 – the associated test methods: static loading of shelves, endurance tests for doors, drawers, and hinges over tens of thousands of cycles.
• DIN 4547-1 and -2 – the specific standard for lockers: Part 1 covers shapes, dimensions, and designation, Part 2 covers functional and safety requirements including tilt resistance and dimensional stability.
• GS mark ("Geprüfte Sicherheit" / tested safety) – a voluntary but meaningful test mark under the German Product Safety Act. An accredited body independently tests stability, strength, and durability. For employers it is a practical selection criterion, since Section 5 of the Ordinance on Industrial Safety and Health only permits safe work equipment in any case.

For the purchasing decision this means: a data sheet that references DIN EN 16121/16122, or DIN 4547 for lockers, signals that the manufacturer has dimensioned the product according to a tested procedure rather than a rough estimate.

Don't forget tip-over protection

An often-overlooked point: even a cabinet built to standard can tip over if it is not installed properly. Tall, narrow cabinets – such as single lockers or narrow compartment cabinets – become top-heavy once loaded, especially when several drawers are open at the same time. As a consequence, the German Workplace Ordinance requires cabinets to be installed so they cannot tip, or to be anchored to the wall. In practice, a simple metal bracket connecting the carcass to the wall is usually enough – a measure that should be documented as part of the risk assessment.

Lockers and changing rooms: what ASR A4.1 actually requires

For lockers in changing rooms, the German Technical Rule for Workplaces ASR A4.1 (sanitary facilities) sets out concrete minimum values that are easily underestimated when planning:

• Minimum locker dimensions: 0.30 m wide × 0.50 m deep × 1.80 m high. PAVOY personal lockers, at 2,150 mm high and 500/800 mm deep, clearly exceed this minimum.
• Movement space: at least 0.5 m² per person while changing.
• Distance between bench and locker row: at least 1.80 m, so two people can dress at the same time without getting in each other's way.
• Distance from locker to door: at least 1.30 m.
• Seating: at least one seat per four employees.
• Separation by sex: above nine employees, separate changing rooms for women and men are required; for smaller workforces, staggered, lockable use is sufficient.

Important for businesses handling hazardous substances or biological agents: if the risk assessment under the Hazardous Substances or Biological Agents Ordinance shows that everyday clothing could become contaminated, a strict separation of personal and work clothing is required. This is usually implemented with double-compartment lockers at least 600 mm wide, with two separately lockable sections – available, for example, as PAVOY personal lockers with 2 to 4 compartments – or through spatially separated changing areas with a washroom in between.

Material, coating, and colour choice

Powder-coated sheet steel is the standard for operational cabinets: robust, non-combustible, economical to maintain. In damp environments – swimming pools, washrooms, outdoor areas – corrosion protection at edges and welds, as well as alternatives such as stainless steel or solid plastic, are worth considering, even though the latter usually fall short on break-in resistance.

In terms of colour, an industry standard has become established: RAL 7035 (light grey) for the carcass, combined with coloured doors – often RAL 7016 (anthracite grey) or RAL 5010 (gentian blue). The practical benefit goes beyond appearance: different door colours make it easier to visually distinguish cabinets in facilities with multiple rows, for instance by department or shift, and can be combined with label frames for names or numbers.

Safety and equipment features in detail

Locking systems

The choice of lock depends on the usage scenario:

• Cylinder lock: individual locking, one key per user or a master key for administration.
• Turn-bolt latch (often three-point): presses the door evenly against the frame, common on heavily used material cabinets.
• Coin lock: for publicly accessible areas such as swimming pools, where no fixed keys are issued.

Ventilation

Ventilation slots in doors are standard on lockers and compartment cabinets and are sufficient for normal drying of work or sports clothing. In heavily used areas – for instance where protective clothing is consistently wet – it is worth considering lockers with active ventilation or larger vent areas.

Care and preserving value

Steel cabinets are low-maintenance, but not maintenance-free. The following points have proven useful for a long service life:

• Regular visual inspection: check hinges, locking mechanisms, and shelf supports for wear and deformation, especially on heavily used lockers.
• Clean surfaces gently: mild cleaners instead of abrasive or solvent-based products, to avoid attacking the powder coating.
• Keep an eye on edges and welds: repair small coating damage promptly, before moisture creeps under the coating and corrosion starts.
• Check tip-over protection regularly: especially after relocations or renovation work that could loosen wall anchors.
• Keep loads within limits: do not permanently push the stated shelf load to its limit – this protects hinges and drawer runners.

Checklist: 8 points before buying a cabinet

• 1. Purpose defined? Tools, clothing, valuables, or sports equipment determine the cabinet type.
• 2. Shelf load and total load adequate? Check both values against the heaviest item you plan to store.
• 3. Space accounted for? Sliding doors for narrow aisles, hinged doors only where there is enough swing clearance.
• 4. Standard stated? Look for DIN EN 16121/16122 or DIN 4547, or a GS mark, on the data sheet.
• 5. Tip-over protection planned? Factor in wall anchoring from the start, not as an afterthought.
• 6. ASR A4.1 dimensions met? For lockers, account for minimum dimensions, movement space, and distances when planning the changing room.
• 7. Is separation of clothing required? Plan for double-compartment lockers where hazardous substances or biological agents are involved.
• 8. Realistic maintenance effort? Match the environment (dry/damp) and the material.

FAQ: frequent questions on operational cabinets and lockers

What is the difference between shelf load and total load in a cabinet?

Shelf load is the permissible weight on a single shelf; total load is the sum across all shelves of a cabinet. Both figures must be observed independently, because the carcass and side panels limit the total load regardless of how the load is distributed across the shelves.

Which standard applies to lockers in Germany?

Lockers are tested to DIN 4547-1 (shapes, dimensions, designation) and DIN 4547-2 (functional and safety requirements, including tip resistance). For fitting out changing rooms, the minimum dimensions and distances of ASR A4.1 also apply.

From when is separation of personal and work clothing required for lockers?

As soon as the risk assessment under the Hazardous Substances or Biological Agents Ordinance shows that everyday clothing could be contaminated by work substances – for example in food processing, laboratories, or waste management. Double-compartment lockers at least 600 mm wide, with two separately lockable sections, are the usual solution.

Does a cabinet have to be fixed to the wall?

Wall anchoring is not mandatory in every case, but the Workplace Ordinance requires stable, tip-proof installation. For tall, narrow cabinets with moving drawers, anchoring is the most practical solution and should be considered as part of the risk assessment.
