Choosing the right shelving material is just as important as selecting the correct rack size and loading capacity. In Malaysia, most boltless racks are supplied with either MDF boards or full metal shelves.

Both options can provide practical and organised storage, but they are suitable for different environments, products and budgets. This guide explains the key differences between MDF board and metal shelf boltless racks so that you can choose the right storage solution for your home, office, shop, storeroom, warehouse or factory.

What Is a Boltless Rack?
A boltless rack is a modular shelving system that can be assembled without using traditional nuts and bolts. The beams and upright frames are connected using a slot-in or interlocking system, allowing the rack to be installed quickly.

Boltless racks are commonly used in:

The rack frame is normally made from steel, while the shelf surface may use MDF boards, metal panels or other suitable decking materials.

What Is an MDF Board Boltless Rack?
An MDF board boltless rack uses medium density fibreboard as the shelf surface. The MDF board rests on the steel beams and centre support bars.
MDF shelving is widely used because it provides a flat, smooth storage surface at an affordable price.
It is suitable for storing:

At Rack Zone, our standard boltless racks commonly use 8 mm MDF boards, subject to the selected rack model and specification.

Advantages of MDF Board Shelves
1. More Affordable
MDF board racks are generally more economical than full metal shelf racks. They are a practical choice for customers who need multiple storage racks within a limited budget.
2. Smooth and Flat Surface
The flat board surface is suitable for cartons, containers and small items that may not sit properly on open beams.
3. Suitable for General Indoor Storage
MDF shelves work well in dry indoor environments such as offices, homes, shops and enclosed storerooms.
4. Easy to Replace
If a board becomes damaged after long-term use, it can usually be replaced without changing the entire rack structure.
5. Suitable for Many Rack Sizes
MDF boards can be prepared according to different rack lengths and depths, making them a flexible option for standard storage requirements.
Limitations of MDF Board Shelves
MDF boards are not waterproof. Continuous exposure to moisture, water leakage or very humid conditions may cause the board to swell, weaken or deform.
MDF shelving may not be the best choice for:

The shelves should also be used according to the stated uniformly distributed load capacity.

What Is a Full Metal Shelf Boltless Rack?
A full metal shelf boltless rack uses steel shelf panels instead of MDF boards. The metal panels are supported by the rack beams and are designed to provide a durable, easy-to-clean storage surface.
Full metal shelves are often selected for offices, commercial storerooms, workshops and environments where customers prefer a more durable shelf material.
They are suitable for storing:

Advantages of Full Metal Shelves
1. Better Resistance to Moisture
Metal shelves do not swell like MDF boards when exposed to occasional moisture. This makes them more suitable for environments where humidity may be a concern.
However, the rack should still be kept in a suitable indoor environment to reduce the risk of rust or corrosion.
2. Easy to Clean
Metal shelves can be wiped down easily, making them suitable for offices, workshops, retail areas and commercial storerooms.
3. Durable Shelf Surface
A metal shelf is less likely to crack, chip or absorb spills compared with MDF board.
4. Professional Appearance
Full metal shelving provides a clean and uniform appearance. It is often preferred for office file storage, retail stockrooms and customer facing commercial areas.
5. Suitable for Long Term Use
When used correctly and maintained properly, metal shelves can provide a durable long-term storage solution.
Limitations of Full Metal Shelves
Full metal shelf racks generally cost more than MDF board racks due to the additional steel material and manufacturing process.
They may also produce more noise when metal tools or products are placed directly onto the shelf. Rubber mats or suitable liners may be added where necessary.

Which Shelf Material Should You Choose?
The best option depends on what you are storing and where the rack will be installed.
Choose MDF Board Shelves When:

Is a Metal Shelf Rack Stronger Than an MDF Board Rack?
The shelf material alone does not determine the full loading capacity of the rack.
The overall rack capacity depends on:

A metal shelf does not automatically mean the rack can support unlimited weight. Customers should always check the stated loading capacity for the exact rack size and model.

Understanding Uniformly Distributed Load
Rack loading capacities are normally based on uniformly distributed load, also known as UDL.
This means the stored weight must be spread evenly across the entire shelf surface.
For example, placing several cartons evenly across the shelf is different from placing one very heavy machine in the centre. A concentrated load may place excessive pressure on one part of the shelf or beam.

To use a boltless rack safely:

Can MDF Boards Be Replaced with Metal Shelves Later?
In some cases, it may be possible to change the shelf material later. However, the new metal panels must match the rack’s exact length, depth, beam design and support structure.
Customers should consult the rack supplier before changing the original decking material. Using an unsuitable panel may affect the fit, stability and load distribution.
Choosing the Correct Boltless Rack Size
Besides the shelf material, customers should also consider the correct rack dimensions.
Important measurements include:

Before ordering, measure the storage area carefully and check for:

Boltless Rack for Office File Storage
For office files and documents, full metal shelves are often preferred because they provide a clean appearance and are easier to maintain.
Smaller rack sizes may also be more suitable for narrow office walkways. Modular boltless racks can be relocated more easily than permanent built-in cabinets, making them useful for businesses that may move or rearrange their office in the future.
MDF board racks can still be used for office storage when the area is dry and the files are stored in boxes or containers.

Boltless Rack for Warehouse and Storeroom Use
For general warehouse and storeroom storage, both MDF board and metal shelf racks can be suitable.
MDF board racks are practical for dry cartons, packaging materials and lightweight stock.
Metal shelf racks may be more suitable for tools, parts, files or items that require a stronger and easier to-clean shelf surface.
For palletised goods, very heavy products or forklift handling, customers should consider a properly designed heavy duty pallet racking system instead of a standard boltless rack.

Why Professional Rack Installation Matters
Correct installation helps ensure that the rack is level, stable and assembled according to its intended design.
During installation, the team should check:

Customers should not remove support bars, beams or structural components after installation.

Frequently Asked Questions
 

MDF board can support suitable loads when it is used with the correct rack structure, beams and centre support bars. The weight must remain within the stated loading capacity and be evenly distributed.
 

Are metal shelves waterproof?
Metal shelves do not absorb water like MDF boards, but the steel may still be affected by long-term exposure to water, chemicals or corrosive environments. They should be kept clean and dry whenever possible.

Which option is better for office files?
Full metal shelves are often selected for office files because they are durable, easy to clean and provide a professional appearance. MDF board shelves may also be used in dry offices.

Which option is cheaper?
MDF board boltless racks are generally more affordable than full metal shelf racks.

Can I use an MDF board rack outdoors?
MDF board racks are not recommended for outdoor areas because exposure to rain and moisture may damage the boards.

Can the shelf levels be adjusted?
Most boltless rack beam levels can be adjusted according to the slot spacing of the upright frame. The rack should be unloaded before any adjustment is made.

How many levels should I choose?
Four levels are common for general storage, but the correct number depends on the height of the products, rack height and required storage capacity.

Does Rack Zone provide delivery and installation?
