MAMMOTH SHELVING UNIT – 400mm Deep

Overview

The Mammoth Shelving Unit – 400 mm Deep (model MRS1040Z) is a heavy-duty, boltless racking bay designed for demanding stores, workshops and warehouses. Built around an interlocking rivet-style system, it assembles quickly without nuts or bolts while delivering impressive rigidity under load. Galvanised beams provide a corrosion-resistant structure, the uprights are finished in a durable Hammerite powder coat, and each shelf is rated to 265 kg U.D.L.—ideal when you need dependable storage that won’t slow down your day-to-day operations.

Key benefits at a glance

• Fast, tool-free build: the interlocking system clicks together securely with no nuts or bolts to fiddle with, so you can install bays quickly and expand as your storage grows.
• Strength you can trust: shelves are rated to 265 kg U.D.L. each, giving reliable capacity for cartons, parts bins and heavier items when correctly distributed.
• Long-lasting finish: Hammerite powder-coated uprights and galvanised beams help resist wear and corrosion in busy industrial environments.
• Space-efficient footprint: the 400 mm depth keeps aisles clear while still providing useful shelf area for tools, components and boxed stock (a 600 mm deep variant also exists in the range).

Sizing & construction

This MRS1040Z bay measures 1800 mm (H) × 1000 mm (W) × 400 mm (D), making it a versatile choice for general storage runs, packing areas and back-of-house stockrooms. The frame is steel with galvanised beams and Hammerite-finished uprights; shelf decks are supplied in plywood according to the client specification. Colour is Anthracite Grey. (Dimensions, colour and materials per client data; construction and finishes corroborated across manufacturer literature.)

Assembly & adjustability

The rivet-style uprights and beams locate positively for a rigid result with minimal effort. Because there are no bolts, you can position shelves at practical heights for your workflow and reconfigure later as inventory changes. The boltless design also means minimal tools are required—handy when you’re fitting out multiple bays on a tight schedule.

Load guidance

Each shelf is rated to 265 kg U.D.L. (uniformly distributed load). In practice, that means the weight should be spread evenly across the deck—avoid point loads, overhangs and concentrated weights. Heavier items are best stored on the lower levels to aid stability and safe manual handling. These guidelines mirror general practice for heavy-duty boltless shelving and the Mammoth range specification.

Where it works best

• Warehouses & distribution: create tidy pick faces with high shelf capacities and quick assembly for new runs.
• Workshops & engineering stores: a robust bay for tools, consumables and spares that sees daily use.
• Back-of-house retail & e-commerce: compact 400 mm depth keeps walkways clear while providing practical storage volume.

Why choose Mammoth Shelving?

The Mammoth system combines the speed of a rivet-style build with finishes chosen for longevity. The Hammerite powder coat on uprights helps the bay look smart after years of knocks and handling, while galvanised beams deliver extra resistance against scuffs and corrosion. Crucially, the shelves’ 265 kg U.D.L. rating gives real-world capacity without the downtime of over-complex assembly, which is why this format is widely used in industrial and commercial settings.

What’s included

One complete MRS1040Z shelving bay with uprights, beams and shelf decks (five-shelf configuration is typical across Mammoth units in this size class; exact configuration may vary by supplier).

Good to know

• Expand as needed: additional bays can be added to form longer runs; the Mammoth range includes 600 mm deep and corner units to suit different layouts.
• Finish details: Hammerite uprights and galvanised beams are part of the Mammoth heavy-duty spec; verify shelf deck material with your chosen configuration (this listing uses plywood as supplied).
• Model code: MRS1040Z denotes the 400 mm depth unit within the Mammoth range.
