Slotted Angle Rack
The most versatile steel shelving system ever made β perforated angle iron uprights and universal bolt-through connections let you build any storage configuration imaginable, from simple shelves to complex workbenches, display racks, and custom frameworks.

What Is a Slotted Angle Rack?
The original universal shelving system β perforated steel angles that bolt together to create any storage structure you can imagine.

Slotted angle racking β also called perforated angle shelving, steel angle rack, or Dexion-type shelving β is a universal steel storage system built from L-shaped (angle iron) profiles punched with rows of slots and holes along both flanges. These perforations allow bolts, nuts, and clips to connect at any point along the angle, enabling unlimited configurations: standard shelving, corner units, L-shapes, U-shapes, workbenches, display stands, trolleys, and even structural frameworks.
Unlike proprietary racking systems that lock you into one configuration, slotted angle is truly open-source β the angles can be cut to any length with a hacksaw, drilled for custom mounting, and combined with steel, MDF, or wire mesh shelves. This makes it the go-to system for workshops, retail stores, schools, offices, and any application that demands maximum customisation at minimum cost. Load capacity ranges from 100-500kg per shelf depending on the angle gauge and shelf span.
Unlimited Configurations
Build shelves, workbenches, trolleys, or frameworks β the only limit is your imagination
Cut-to-Length
Angles can be cut with a hacksaw to any length for truly custom-fit installations
Lowest Unit Cost
The most affordable industrial-grade steel shelving system on the market
Universal Bolt Connection
Standard M6/M8 bolts and nuts β replaceable, available anywhere, zero lock-in
Storage Challenges Solved
Common frustrations with off-the-shelf storage solutions β and how slotted angle racks eliminate every single one.
Fixed Sizes Only
Standard shelving comes in pre-set widths, depths, and heights that never quite fit your exact space requirements.
β Cut angles to any length you needProprietary Lock-In
Branded racking systems use proprietary connectors β replacement parts are expensive and only available from one supplier.
β Standard M6/M8 bolts, available globallyHigh Setup Costs
Custom storage solutions require expensive engineering, specialised fabrication, and professional installation.
β DIY assembly with basic hand toolsCannot Repurpose
When storage needs change, fixed shelving becomes scrap β it can't be reconfigured into a different structure.
β Unbolt, rebuild into anything newOne Shape Only
Most shelving systems only make rectangular shelves β no corner units, L-shapes, workbenches, or custom structures.
β Build any shape: L, U, corner, benchInconsistent Quality
Budget angle iron from local markets varies in gauge, hole alignment, and finish β leading to wobbly, uneven assemblies.
β Precision-punched, factory QC'd steelBuilt for Total Flexibility
Every aspect of slotted angle racking is designed for maximum customisation β the original open-source steel shelving system.
Universal Bolt Connection
Standard M6/M8 bolts and nuts connect at any slot position along both flanges β no proprietary hardware, no vendor lock-in.
Cut to Any Length
Angles are easily cut with a hacksaw, angle grinder, or band saw to create perfectly fitted uprights and cross-members.
Powder-Coated Finish
60-100ΞΌm electrostatic powder coat in custom RAL colours provides corrosion resistance, scratch protection, and clean aesthetics.
Up to 500kg per Shelf
Heavy-gauge angles (2.0-3.0mm) with proper bracing support up to 500kg per shelf level for industrial parts and bulk goods.
Infinite Configurations
Build shelves, workbenches, tool boards, display stands, trolleys, partitions, or structural frames β the only limit is imagination.
Ultra Flat-Pack
Angles nest together for extremely compact shipping β up to 500+ sets per 20GP container for the lowest freight cost available.
100% Reusable
Unbolt, reconfigure, and rebuild into completely different structures as your storage needs change β zero material waste.
Custom Sizes & Colours
Any RAL colour, any angle gauge, any length. Standard profiles from 30Γ30mm to 50Γ50mm with custom options available.
Slotted Angle Configurations
From simple warehouse shelves to complex custom workstations β slotted angle profiles enable six core application types and beyond.

Standard Shelving
Classic rectangular shelving units with 3-6 shelf levels. The most popular configuration for warehouses, stockrooms, and retail back-of-house storage applications.

Heavy-Duty Industrial
Thicker gauge angles (2.5-3.0mm) with additional bracing for loads up to 500kg per shelf. Designed for workshop parts, auto components, and heavy tool storage.

Corner & L-Shape Units
Custom corner configurations and L-shaped shelving that maximise awkward spaces. Built by joining standard angles at 90Β° with gusset plates or direct bolting.

Workbench & Workstation
Slotted angle frames with solid worktops, tool pegboards, overhead shelving, and drawer mounts β creating ergonomic assembly, packing, and repair stations.

Multi-Tier System
Stack 2-3 levels of slotted angle shelving with walking platforms and stairs. Cost-effective alternative to mezzanine racking for small-parts picking operations.

Display & Retail Rack
Open-frame display shelving for retail showrooms, garden centres, and trade shows. Angles powder-coated in brand colours with optional signage brackets and hooks.
System Components
Simple, universal components β just angles, shelves, bolts, and brackets. Everything you need to build any storage structure.

Slotted Angle Profiles
L-shaped steel angles (30Γ30 to 50Γ50mm) with precision-punched slots on both flanges at uniform pitch. 1.5-3.0mm gauge Q235B steel.
Shelf Panels
Steel panels (0.5-1.0mm), MDF boards, wire mesh, or plywood shelves. Cut to size and placed on angle supports. Can be bolted or drop-in.
Bolts, Nuts & Washers
Standard M6 or M8 hex bolts with nuts and flat washers. Grade 4.8 or 8.8 depending on load requirements. Zinc-plated for corrosion resistance.
Gusset Plates
Corner bracing plates for reinforcing right-angle joints and adding structural rigidity. Essential for tall units and heavy-load configurations.
Foot Pads & Levellers
Plastic foot caps or adjustable levelling feet protect floors and compensate for uneven surfaces. Optional rubber anti-vibration pads.
Accessories
Hooks, label holders, dividers, shelf lips, back panels, and casters. Transform standard shelving into specialised storage for any application.

Assemble Side Frames
Bolt two uprights and cross-members together to form two side frames. Tighten bolts finger-tight to allow adjustment.
Connect Front & Back
Join the two side frames with front and back horizontal angles at your desired shelf heights. Check square with a measuring tape.
Add Bracing & Shelves
Install diagonal bracing on the back face for stability. Drop or bolt shelf panels onto the angle supports at each level.
Tighten & Level
Final-tighten all bolts with a wrench. Attach foot pads or levellers. Your custom slotted angle rack is ready to load.
