Definition: Roll-out Rack for Sheet Metal is Long Quyền’s heavy-duty storage system, designed with drawer layers that can slide out 100% thanks to a load-bearing ball bearing system. This solution allows cranes to lift sheet metal/molds directly from above, saving 70% of warehouse space compared to floor storage.
1. Optimal Solution for Mechanical & Mold Warehouses
Storing large sheet metal (1.2m x 2.4m) or heavy molds weighing tons is always a challenging problem. Storing on the floor takes up space, while storing on Selective racks makes it difficult for forklifts to access.
Long Quyền Racks introduces the Roll-out Rack solution – A breakthrough in optimizing mechanical workshop space:
✅ Saves 70% of space: Stacks multiple layers vertically.
✅ Operated by Crane: Drawers open 100%, making it easy to hook goods with a crane.
✅ Absolute Safety: Interlocking system prevents sliding.
2. Structure & Operating Mechanism
The rack system is designed like a giant steel drawer cabinet:
Upright Frame: I or H-shaped cast steel, ensuring resistance to large vibrations.
Guide Rail: Uses ultra-heavy-duty load-bearing bearings, allowing an average person to pull a 2-ton drawer with one hand.
Drawer Surface: Sheet metal or skeletal frame, suitable for sheet metal, casting molds, engines.

Specifications of the sliding rail sheet metal rack
Main structure and functions
- The slide rack design allows the steel plates to be stacked horizontally or inclined, easy to move and operate.
- The heavy-duty frame is made of high-quality steel, powder coated or galvanized, rust-resistant – suitable for both indoor and outdoor environments.
- The design load typically ranges from 1,000 kg to 5,000 kg per level, equivalent to or exceeding the load of anti-slip sheet metal.
Compatible with anti-slip ribbed sheet metal
- Anti-slip steel plates are usually available in thickness from 3mm to 12mm, standard sizes such as 1250×6000 or 1500×6000 mm.
- Railed shelves are suitable for stacking or tilting panels, making room use and easy entry and exit.
Outstanding advantages of using sliding rail sheet metal racks
Optimize storage space
- The panels can be placed into inclined rows or vertical stacks depending on the warehouse design, saving space.
- Slide rails make it easy to retrieve each plate without unloading the entire stack.
Enhanced safety and performance
- Rail mounting helps to limit random movement and slippage.
- Reduce the risk of loss or damage due to impact between plates.
Flexible use – indoors & outdoors
- Shelves design with a roof or protective layer (galvanized), suitable for outdoor placement while still protecting the steel from rust and environmental impacts.
- Inside the warehouse: moisture-proof and corrosion-resistant paint, ensuring a long service life.
High load capacity & superior durability
- Large bearing steel frame, industry standard design.
- Solid construction, less prone to deformation over time – suitable for well-thought-out storage of ribbed steel plates, carbon steel or stainless steel.
4. The process of installing shelves for steel plates
Step 1: Survey the space and goods
- Measure warehouse size, ceiling height, light location, environmental humidity.
- Volume of steel plates, specifications of each type, frequency of import and export.
Step 2: Schematic design and shelf configuration
- Decide on the number of rails, tilt angle, the ability to easily retrieve each sheet.
- Calculate dynamic and static force loads, select suitable outdoor plating paint materials if necessary.
Step 3: Processing and construction
- Precision machining of steel frames, rails, platforms.
- Erect according to a safe process, brace the rails to prevent displacement.
Step 4: Test operation and handover
- Load test, plate slip test, structural stability test.
- Instruct personnel in routine operation and maintenance.
5. Practical application & example of racking to steel plate
5.1 Manufacturing and manufacturing plants
- Store ribbed steel plates, ordinary steel, aluminum sheets – inclined stacking forms to help employees quickly choose according to the unit used.
- Improve inlet and output flow, reduce errors in selecting thickness error plates.
5.2 Commercial, mechanical, shipbuilding storage
- With ribbed steel plates are widely used in industrial floors, stairs, ramps, harbors… This shelf system is stored in accordance with the technique, avoiding abrasion when exposed to the environment.
5.3 Outdoor – distribution warehouses, storage yards
- Mounting shelves with a roof or plated cover help protect the steel from rain, sun and rust when left outdoors for a long time.
6. Economic and technical benefits when investing in shelves for steel plates
- Save storage costs: Reduce the usable area, increase the capacity without expanding the factory.
- Reduce cargo loss: No direct collision between plates, limit scratches, warping.
- Increased operating productivity: Quick access, reduced plate picking time, simple shelf maintenance.
- Long service life: The device is durable, easy to handle if damaged, suitable for humid or outdoor environments.
Shelves with Stacked Sliding Rails for Outdoor Steel Plates
7. Compare the racking solution for steel sheet rail slides with other storage
| Criteria | Shelves with stacked sliding rails | Direct stacking on pallets/normal shelves |
|---|---|---|
| Retrieval Plate | Easy, individually | The entire stack had to be removed to get the sheet underneath |
| Collision losses | Maximum Limitations | It is very easy to impact and damage the plate surface |
| Optimize the area | High, tilted rails help stack neatly | Must be divided into thicker layers, larger area |
| Suitable for the outdoors | With suitable canopy/plating | Unprotected, easy to rust |
| Installation costs | Higher initially, but long-term savings | Cheap prices, but increased wear and tear of goods |
8. Guide to selecting shelves for steel plates to suit your needs
8.1 Determining the type of steel plate
- If you store anti-slip ribbed steel plates, the inclined rail lever guides each plate.
- If it is stainless steel or plain carbon steel, still use rails but different levels of friction, so the design is suitable.
8.2 Selecting the load and number of floors
- According to the specification: each load-bearing rail layer needs to be higher than the maximum plate weight.
- It is recommended that there be a gap between the plates for easy handling (not tight pressing).
8.3 Selecting Materials and Coatings
- Indoor: anti-rust powder coating.
- Outdoor: choose galvanized or anti-oxidation coating.
8.4 After-sales service, maintenance
- The supplier should have a policy of periodic inspection.
- The mode supports rail replacement, repainting, and fixing when the rail is distorted or rusty.
9. Why is Long Quyền’s Roll-out Rack safer?
Drawer rack collapses often occur due to weak rails or loss of balance (pulling multiple drawers at once). At Long Quyền Factory (Xuân Phương), we apply dual safety standards:
Cast Steel Material: We do not use thin bent steel; we use solid cast steel for main load-bearing components.
Interlocking Mechanism: The smart mechanical system requires you to close one drawer before opening another -> Completely eliminates the risk of rack tipping.
10. FAQs – 6 Frequently Asked Questions
1. What is a rack for steel plate with stacked sliding rails?
- It is a shelf system with inclined rails for storing steel plates, which makes it easy to stack in rows and pull out plates without unloading the entire stack, suitable for ribbed or plain steel plates.
2. How much load does this shelf withstand?
- Normally, each rail deck can withstand a load of 1,000 kg to 2,000 kg depending on the technical configuration and frame design.
3. Can it be used outdoors?
- Yes, if choose a galvanized or covered frame type – make sure the steel plate does not rust or oxidize over time.
4. Are slide rails easy to break or jam?
- With proper installation and periodic maintenance, the rails work smoothly and are not easy to jam. If it is deformed, it can be replaced with a simple rail.
5. Is it mandatory to use sliding rails for ribbed steel plates?
- Optional, but highly recommended because the rails make it easy to retrieve the plate, reduce rib edge damage, and save sorting effort.
6. What is the installation time and cost?
- Depends on the scale: usually a few days to a week for survey, processing, erection and acceptance. The initial cost is higher than conventional shelves, but long-term savings are achieved by reducing losses and increasing operational efficiency.
