Site Office 4 Drawer Metal Filing Cabinet – Lockable, 30kg per Drawer

A site office 4 drawer metal filing cabinet – lockable, 30kg per drawer provides secure document storage for construction site managers who need to protect site plans, safety records, personnel files, and equipment inventories in portable cabins. For example, this model is perfect for site offices where valuable documents must be kept safe from theft, dust, and site damage. However, unlike domestic filing cabinets that buckle under heavy loads, this unit features reinforced steel construction and heavy-duty drawer runners rated for 30kg each. As a result, you receive commercial-grade storage that withstands the daily demands of active site environments. Learn about site security and document protection from official HSE guidelines.

Why Choose a Heavy-Duty Metal Cabinet for Your Site Office?

Flimsy cardboard or plastic storage boxes are not secure for site offices. In contrast, this lockable metal cabinet offers robust protection against theft, fire, and site dust. Consequently, the four-drawer configuration provides ample storage for A4 and foolscap suspension files. Moreover, each drawer holds up to 30kg – enough for heavy site binders, tool catalogues, and box files. Thus, you gain both security and capacity. See site office storage ideas on Pinterest for layout inspiration.

Key Features of This Site Filing Cabinet

The lockable mechanism is the defining feature of this unit. For instance, the central locking system secures all four drawers simultaneously with a single turn of the included key. Similarly, the 30kg per drawer capacity allows you to store heavy items without risking drawer collapse. Furthermore, the high drawer depth (300mm) accommodates suspension files, lever arch binders, and site plan folders standing upright. Finally, the powder-coated grey finish resists scratches and site dust. Check UK site security regulations before ordering furniture.

Drawer Configuration and Capacity

This cabinet is designed for maximum organised storage. For example, each drawer accepts A4 (foolscap) suspension files running front to back. Likewise, the 30kg weight capacity per drawer means you can store heavy site manuals, tool catalogues, and box files without overloading. If you need lighter-duty storage, each drawer still functions perfectly for lighter paperwork.

Durability for Harsh Site Conditions

Site offices are demanding environments. First, this cabinet uses 0.8mm cold-rolled steel (not thin 0.5mm) that resists denting and warping. Second, powder-coated finish protects against rust and moisture from damp site huts. Third, heavy-duty drawer runners are rated for 30kg with ball-bearing operation. Finally, the reinforced base prevents sagging even when fully loaded. Read our site office furniture durability guide before purchasing.

What’s Included and Optional Upgrades

First, every order includes the welded steel cabinet body with four drawers. Second, two keys are included for the central locking mechanism. Third, suspension file rails are pre-fitted in each drawer (A4/foolscap compatible). Finally, adjustable levelling feet are fitted to compensate for uneven site floors.

For instance, add a matching two-drawer cabinet for side-by-side placement. Likewise, anti-tilt brackets can be added (wall-mount) for earthquake or safety compliance. Contact our site office team for bulk orders of 5+ units. See our site office furniture guide for all options.
