Reinforced Shelving Unit with 2 Shelves — A Reliable Foundation for Professional Storage of Heavy Goods
A two-tier reinforced shelving unit is a fundamental solution for businesses that require maximum reliability when storing heavy and oversized goods. This design combines engineering excellence, economic efficiency, and versatility of application.
Engineering Solutions and Structural Strength
The shelving unit is based on a reinforced frame made of high-quality structural steel grade St3sp with a thickness of 2.5–3.0 mm, providing exceptional resistance to critical loads of up to 500–800 kg per shelf. Vertical uprights feature a closed box-section profile of 80×40 mm with a wall thickness of 2.0 mm, ensuring an optimal balance between strength and overall weight.
Horizontal load-bearing elements are manufactured from 40×20 mm rectangular tubing and ensure rigidity of the frame in the horizontal plane. Additional diagonal braces made from 25×25 mm profiles create spatial rigidity and prevent deformation under uneven loading.
Shelves are produced from 2.0 mm sheet steel using bending technology with formed reinforcing ribs. Shelf edges are double-folded, adding extra strength and operational safety. The shelf surface features a textured pattern to increase grip and prevent items from slipping.
Fastening and Installation System
The innovative fastening system is based on bolted connections using high-strength bolts of strength class 8.8. All critical joints are reinforced with additional plates and brackets to ensure uniform load distribution and eliminate stress concentration.
Shelf height adjustment is achieved via a perforation system with a 50 mm pitch, allowing precise adaptation to specific product dimensions. Special locking pins securely hold the shelves even under dynamic loads during loading and unloading operations.
The base of the shelving unit is equipped with adjustable feet that compensate for floor unevenness of up to 15 mm. This ensures stability even on uneven surfaces and allows installation without prior floor preparation.
Protective Coatings and Corrosion Resistance
All metal components undergo a full surface preparation cycle, including shot blasting to remove scale and rust, alkaline degreasing, phosphating to create an adhesion layer, and application of a powder coating with a thickness of 80–100 microns.
The polyester-based powder coating provides excellent resistance to mechanical damage, chemical exposure, and ultraviolet radiation. The standard color range includes industrial colors such as gray RAL 7035 for universal use, blue RAL 5015 for warehouse facilities, and green RAL 6011 for industrial sites.
Special coating options include hot-dip galvanizing for high-humidity environments, powder coating with antibacterial additives for food industry applications, and coatings with enhanced chemical resistance for chemical plants.
Workflow Optimization and Ergonomics
The two-tier design ensures optimal use of room height while maintaining maximum ease of use for personnel. The lower shelf is positioned at a height of 400–500 mm from the floor, allowing heavy items to be lifted without excessive strain on the back.
The upper shelf, located at a height of 1200–1400 mm, remains accessible for most employees and can support loads of up to 300–400 kg without lifting equipment. This configuration is ideal for zoning principles: heavy goods on the lower shelf, medium-weight items on the upper shelf.
The distance between shelves of 800–900 mm accommodates boxes, containers, and packages of various heights. If required, this distance can be increased to 1200 mm for bulky goods. Shelf depth of 600–800 mm provides an optimal balance between capacity and accessibility.
