Slotted Angle Racks
Ralbo Engineering is a leading manufacturer of slotted angle racks — the most versatile and economical storage system for warehouses, stores, workshops and offices. Also known as slotted angle shelving, these racks are built from pre-punched steel angles that bolt together to form rigid, fully adjustable shelving without any welding. From our manufacturing facility in Greater Noida, we supply standard and custom slotted racks across India and to export markets, engineered for strength, durability and long service life.
A slotted angle is a system of reusable steel strips with regularly spaced pre-punched holes. Because shelves bolt on at any slot position, the system can be assembled, extended, relocated and reconfigured as your storage needs change — making it the go-to solution for organising light-to-medium loads such as cartons, spare parts, files, tools and finished goods.
What Are Slotted Angle Racks?
Slotted angle racks combine two simple but engineered components — slotted angles and shelf panels — into a stable storage structure. The slotted angles act as the vertical and horizontal framework, holding the whole construction together and giving it the right size and shape. Pre-punched holes along each angle allow shelves to be positioned and re-positioned at the exact heights you need.
Nuts and bolts hold the structure together. Forged from quality steel and galvanised for added strength and corrosion resistance, they lock the slotted angles and shelves into a firm, square frame. Cladding sheets — plain steel or alloy panels with pre-punched ends — serve as shelves and can also divide compartments or close in the sides of the rack.
Key Features
- Fully adjustable shelving — pre-punched slots let you set and change shelf heights without tools-down rework or welding.
- Bolted, reconfigurable design — assemble, extend, relocate and reconfigure bays as your storage needs evolve.
- Solid steel construction — roll-formed slotted angles and steel shelf panels for a rigid, stable structure.
- Galvanised nut-bolt assembly — corrosion-resistant hardware engineered for strength and durability.
- Powder-coated and galvanised finishes — protective coatings for long life in humid, dusty or industrial environments.
- Light-to-medium load capacity — shelf ratings configured to suit cartons, parts, files and stock.
- Custom sizes — bay height, width and depth, shelf count and panel type built to your specification.
