HNSJ-29m16F Double-Sided Library Stacks: H2000mm Premium Steel & Wood Bookshelf for School & University Projects
Double-Sided Library Stacks Product Vision: Evolution of Knowledge Storage
In the design of modern libraries, archives, and large-scale information centers, the storage system is no longer a static piece of furniture. It is a dynamic infrastructure that must prioritize flexibility, scalability, and structural integrity.
The HNSJ-29m16F Double-Sided Library Shelving System, manufactured by Luoyang Hengna Office Furniture Co., Ltd., is engineered to meet these high-standard requirements. By combining high-grade cold-rolled steel with the warm aesthetics of yellow wood grain finishes, this system offers a professional solution for school, university, and corporate library projects. Its core philosophy—“Limited Modules, Infinite Possibilities”—allows institutions to start small and expand their storage capacity seamlessly as their collections grow.

Core Advantage: The Modular Expansion System
The most revolutionary feature of the HNSJ-29m16F is its Starter and Add-on (Main & Sub-frame) architecture. This is a game-changer for B2B project managers and space planners.

1. Starter vs. Add-on Explained
- The Starter Unit (Main Frame): This unit is completely self-standing with two upright columns. It can be placed anywhere as an independent storage island.
- The Add-on Unit (Sub-frame): Designed to save cost and space, the add-on unit consists of only one upright column and shares the adjacent column of the Starter unit.
- Infinite Extension: You can connect an unlimited number of add-on units to a single starter unit to create a continuous, rock-solid wall of books.
2. Why Choose Modular?
- Cost Efficiency: By sharing uprights, the cost per linear meter of shelving is significantly reduced in large projects.
- Structural Unity: A connected row of shelving is inherently more stable than multiple independent units placed side-by-side.
- Future-Proofing: Budget constraints often limit initial purchases. With this system, you can install a few starter units this year and add extension units next year without any mismatch in design.
Functional Design for High-Capacity Environments
Double-Sided Efficiency
The HNSJ-29m16F utilizes a Double-Sided design, meaning it offers access from both sides. With a depth of 450mm, it effectively doubles the storage volume within the same floor footprint. This makes it the ideal choice for:
- Central Row Stacks: Creating aisles in large open-plan libraries.
- Space Partitioning: Using the shelving to define reading zones vs. quiet zones without building permanent walls.
Adjustable Laminates & Butterfly Hole Precision
Every collection is unique, from tall architectural folios to small paperback novels. Our Adjustable Laminate System utilizes the precision-engineered Butterfly Hole design:
- Tool-Free Adjustment: Move shelves up or down in seconds to eliminate wasted vertical space.
- Security: Once locked into the butterfly holes, the shelves remain perfectly level even under heavy loads.
- 6-Tier Standard: Provides a generous amount of surface area for massive book collections.
Material Excellence & Human-Centric Engineering
Industrial-Grade Steel Frame
The backbone of the HNSJ-29m16F is made from premium cold-rolled steel. Our manufacturing process involves:
- Laser Cutting & Precision Bending: Ensuring every joint fits perfectly.
- Environmental Powder Coating: The white frame is treated with an electrostatic spray that is scratch-resistant, anti-rust, and easy to sanitize.
- Reinforced Columns: The double-column structure is designed to prevent swaying, ensuring safety in public areas.
Warm Aesthetic Wood Finish
The yellow wood grain shelves serve a dual purpose. They provide a warm, natural contrast to the clean white metal frame, reducing the “industrial” feel of the library and creating a more inviting, studious atmosphere. The wood finish is moisture-resistant and designed to withstand the friction of books being pulled and replaced thousands of times.
Safety & Ergonomics
- Anti-Tip Design: The base is wide and stable, suitable for anchoring to the floor for added safety.
- Round Corner Finishing: All exposed metal and wood edges are polished to prevent injuries in high-traffic school environments.
- Base Kick-Plate: Prevents dust and debris from accumulating under the bottom shelf and protects books from floor-level moisture.

B2B Application Scenarios
The HNSJ-29m16F is specifically designed for large-scale institutional use:
- University Libraries: Perfect for managing expansive academic collections and archival research materials.
- Public Library Systems: The modularity allows for easy reconfiguration as community needs change.
- K-12 Schools: Durable enough for younger students and adaptable for different textbook sizes.
- Corporate Archives: Provides a professional, organized look for legal, medical, or technical documentation.
- Commercial Bookstores: The warm wood grain makes it an excellent retail display for premium book collections.
