Heavy Duty Metal Blueprint Cabinets: The Ultimate A0 & A1 Storage Solution for Architects
When it comes to architecture, engineering, and design, the accuracy of your documents is the most important thing. You spend hundreds of hours making detailed plans, topographical maps, and engineering diagrams. But a lot of companies still use cardboard tubes or messy wire racks to store these works of art.
The end result? Curled edges, tears, fading from being in the light, and the annoyance of having a document snap back on you when you try to unroll it.
Enter the Heavy Duty Metal Blueprint Cabinet (often called a flat file or plan chest). This is not just a piece of furniture; it is an asset protection system. At Luoyang Hengna Office Furniture Co., Ltd., we understand that professional drawings require professional storage. Whether you are looking to store A0 posters or A1 architectural plans, our steel cabinets offer the durability, organization, and aesthetic appeal that modern firms demand.

Why “Flat” is the Only Way to Store Large Formats
Before diving into the technical specifications, it is essential to understand why flat storage is the industry standard for large-format documents.
1. Preservation of Document Integrity
When paper is rolled, the fibers are stressed. Over time, this creates a “memory” in the paper, making it difficult to lay flat for presentation or digitization. Our flat file cabinets keep documents perfectly horizontal, ensuring they are ready for the boardroom or the construction site immediately.
2. Maximize Vertical Space
Floor space in design studios is expensive. Our cabinets are designed to be modular and stackable. As seen in our product lineup, you can stack multiple 5-drawer sections to create a high-density storage tower without increasing the cabinet’s footprint.
3. Protection from Environmental Factors
Open racks expose paper to dust, humidity, and UV light (which fades ink). A heavy-duty steel enclosure provides a sealed environment, protecting your intellectual property from the elements and accidental coffee spills.
Product Spotlight: Engineered for Efficiency
At Luoyang Hengna, we don’t just bend metal; we engineer solutions. Let’s break down the specific features of our blueprint cabinets that set them apart from standard office furniture.
Smooth Operation Under Heavy Loads
A common complaint with cheaper flat files is that the drawers stick or jam when fully loaded with heavy paper stock.
As shown in the detail image above, our cabinets utilize a specialized bottom roller system.
- Free Assembly Interaction: The roller design ensures that even when the drawer is full of heavy A0 blueprints, the friction remains low.
- Durability: The wheel is crafted from high-grade, impact-resistant nylon that glides silently against the steel track.
- Accessibility: This mechanism allows the drawer to extend fully, giving you access to the documents at the very back without risking the drawer falling out.
Classification and Quick Identification
In a busy firm with hundreds of active projects, finding “Project X – Elevation B” instantly is crucial.
Our cabinets feature an integrated, stamped steel label holder (also visible in the detail image). Unlike stick-on labels that peel off over time, our label slots are embossed directly into the drawer face.
- Standard Size: Fits standard card stock for easy labeling.
- Visibility: Positioned ergonomically for quick scanning.
- Aesthetics: The sleek, recessed design maintains the modern, clean lines of the cabinet.
Technical Specifications: A0 vs. A1 Solutions
We offer versatility to match your specific storage needs. Our cabinets generally come in two primary footprint sizes, designed to accommodate the ISO standard paper sizes A1 and A0.
Here is a breakdown of the dimensions of Heavy-Duty Metal Blueprint Cabinets:
| Feature | Model A (Compact / A1) | Model B (Large / A0) |
| Total Width | 1000 mm | 1300 mm |
| Total Depth | 700 mm | 930 mm |
| Drawer Configuration | 5 Drawers per section (Stackable) | 5 Drawers per section (Stackable) |
| Material | Cold-Rolled Steel | Cold-Rolled Steel |
| Finish | Electrostatic Powder Coating | Electrostatic Powder Coating |
| Handles | Heavy-duty side carrying handles | Heavy-duty side carrying handles |
| Ideal For | A1 Plans, Art Prints, Maps | A0 Blueprints, CAD Plots, Posters |
Key Structural Highlight: Note the side handles on the units shown above. These are heavy-duty, industrial-grade handles. Because these units are modular, these handles allow you to safely lift and rearrange the stacked sections as your office layout changes.
The Luoyang Hengna Advantage: OEM & ODM Services
You might be reading this as an office furniture distributor, a procurement manager, or a brand owner looking for a reliable manufacturing partner. This is where Luoyang Hengna Office Furniture Co., Ltd. excels.
Located in Luoyang, the heart of China’s steel furniture manufacturing industry, we specialize in OEM (Original Equipment Manufacturer) and ODM (Original Design Manufacturer) services.

Why Partner with Hengna?
- Customization Capability: Do you need a specific color to match your brand? We offer various color options beyond the standard grey and white. Do you need a unique lock system or a specific drawer depth? Our R&D team can adjust the blueprints to meet your market’s specific needs.
- Material Quality: We use premium cold-rolled steel plates. Before the powder coating process, the steel undergoes rigorous chemical treatment (phosphating) to ensure rust resistance and superior paint adhesion. This results in a “heavy duty” product that resists scratching and denting.
- Scalability: Whether you need 50 units for a boutique design firm project or 500 units for a government archive tender, our production lines are equipped to handle high-volume orders with consistent quality control.
- Global Logistics: We optimize our knockdown (KD) or semi-assembled structures for shipping containers, thereby lowering freight costs for our international partners.
Comparison: Metal vs. Wood for Plan Storage
When choosing blueprint storage, some designers consider wood for aesthetic reasons. However, from a functional and longevity standpoint, steel wins every time.
- Fire Resistance: Steel is non-combustible. In the event of a fire, a metal cabinet offers a much higher chance of your critical documents surviving compared to a wooden chest.
- Pest Resistance: Silverfish and termites love paper and wood. They cannot eat through steel.
- Weight Capacity: A stack of 500 architectural drawings is incredibly heavy. Wooden drawer bottoms often bow or warp under this weight over time. Our reinforced steel drawers remain rigid.
