In the high-pressure environment of modern manufacturing and logistics, floor space is your most valuable asset. The Juntuo Heavy-Duty Industrial Steel Storage Rack, manufactured by Luoyang Hengna Office Furniture Co., Ltd., is not just a shelf—it is a strategic infrastructure upgrade designed to reclaim your vertical space.
Engineered for the rigorous demands of factories, maintenance workshops, and utility rooms, this professional-grade storage solution focuses on making storage “More Solid and Safer.” By utilizing premium Cold Rolled Steel and a revolutionary tool-free snap-in assembly system, we provide a storage backbone that organizes materials, tools, and spare parts efficiently. Whether you are storing heavy lubricant drums, bulk spare parts, or large archival boxes, Juntuo racks offer the strength and flexibility to handle it all.

Heavy-Duty Industrial Steel Storage Rack Core Features & Engineering Excellence
1. Revolutionary “Boltless” Snap-in Assembly Forget the hassle of nuts, bolts, and specialized tools. Our rack features a cutting-edge Butterfly Hole Design.
- How it works: The hooks on the beams simply snap into the butterfly-shaped holes on the upright columns.
- The Benefit: Installation speed is increased by 300% compared to traditional shelving.
- Gravity Lock: The design utilizes gravity and weight load to create a “self-locking” mechanism. The heavier the load, the tighter the joint becomes, ensuring superior stability.
2. The Cost-Saving “Main & Sub-Frame” System We understand industrial scalability. Our system allows for infinite expansion using a smart connection method:
- Main Frame: A standalone unit with two upright columns.
- Sub-Frame: An add-on unit with only one upright column, which shares a column with the adjacent Main Frame.
- Value: This design reduces the number of columns needed for long rows of shelving, significantly lowering your procurement costs and saving installation space without compromising strength.
3. Extreme Load Capacity (100-300kg per Layer) Built for heavy lifting. The beams and uprights use thickened, reinforced Cold Rolled Steel.
- Long-Span Design: Optimized for storing wide items like pallets, oversized toolboxes, and bulk inventory bins.
- Stability: The structure is rigid and wobble-free, ensuring safety for personnel working in the aisles.
4. Industrial-Grade Finish Available in classic Industrial Blue (for high visibility and safety) or Matte White (for clean utility rooms). The surface is treated with a High-Strength Electrostatic Powder Coating.
- Resistance: It resists abrasion, corrosion, and chemical spills (common in maintenance rooms), ensuring the rack looks professional for years.
Ideal Application Scenarios
This rack is versatile enough to serve as the backbone for various industrial sectors:
- Manufacturing & Production Floors: Perfect for creating “Line-Side Storage” for raw materials, semi-finished goods, and fast-moving spare parts. Keeps the assembly line uncluttered and efficient.
- Maintenance & Repair Operations (MRO): The high load capacity makes it ideal for storing heavy motors, pumps, power tools, and drums of industrial fluids in maintenance workshops.
- Warehousing & Logistics Centers: Acts as a robust solution for bulk carton storage or long-term archival of goods. The long-span shelves accommodate large plastic totes perfectly.
- Utility Rooms & Archives: Organize facility management equipment, cleaning supplies, or heavy technical files in server rooms or administrative archives.

Understanding the “Main vs. Sub Frame” Advantage
To help you plan your layout and budget effectively, it is crucial to understand the modular nature of our racks.
- The Main Frame (Starter Unit): Consists of 2 Upright Columns. This is an independent unit that can stand alone. You need at least one Main Frame to start a row.
- The Sub-Frame (Add-On Unit): Consists of 1 Upright Column. It attaches to the Main Frame by sharing a column.
- Example: If you need a row of 5 racks, you purchase 1 Main Frame + 4 Sub-Frames.
- Result: You save the cost of 4 upright columns!

FAQ (Frequently Asked Questions)
Q1: Is the “Tool-Free” installation really stable enough for heavy industrial use?
A: Absolutely. The stability comes from physics. The “Butterfly Hole” connector creates a wedge effect. As you place weight on the shelves, the beam pushes down into the tapered slot of the column, locking it tighter. It is just as stable—if not more so—than bolted connections, with the added benefit of never vibrating loose over time.
Q2: How many Sub-Frames can I connect to one Main Frame?
A: Theoretically, there is no limit. You can extend the racking system as long as your warehouse wall permits. However, for practical access and safety, we recommend planning your aisles according to forklift or walkway width requirements.
Q3: Are the shelf heights adjustable?
A: Yes. The upright columns feature punched holes at regular intervals (usually every 50mm or 75mm). You can unclip the beams and move them up or down to customize the vertical space between shelves, accommodating items of varying heights like tall machinery or short boxes.
Q4: Can I customize the dimensions to fit my specific factory layout?
A: Yes, OEM/ODM is our specialty. If standard sizes do not maximize your space, we can manufacture racks to your specific Length, Width, and Height requirements. We can also adjust the steel thickness to meet specific load-bearing certifications.
