Beam Bar is the most important horizontal load-bearing component of the Pallet rack, connecting two column frames to support goods. At Long Quyen, the Beam bar is made from stamped steel in box profile or Z shape, with load capacity ranging from 1,000 – 6,000 kg/level, ensuring a safety deflection standard of 1/200 of the length.

1. Overview of Beam Bar of Pallet Rack

The beam of the pallet rack is an important component in the pallet rack system, acting as the main load-bearing horizontal beam, helping and distributing the load from the pallet and goods on each rack (giakelongquyen.com). Beam is the connection between the pillars (omega column), usually designed in the form of a strong H-box bar, ensuring safety when storing heavy pallets.

The selection of the right beam in accordance with the load, pallet size and warehouse layout design plays a decisive role in the durability, safety and efficiency of using warehouse space.

2. Beam technical structure of pallet rack

SPECIFICATIONS	Long Quyen STANDARDS	CUSTOMER BENEFITS
Material	Steel JIS G3101 SS400 (Japan)	Better tensile & bending strength than regular CT3 steel, durability > 20 years.
Steel thickness	1.5mm – 2.0mm – 2.5mm	Various options to optimize costs according to each load capacity.
Hook structure	3-prong or 4-prong hook	Firmly grips Omega column, eliminates shaking, prevents dislodging upon impact.
Safety pin	Automatic lock (Safety Lock)	Prevents Beam bar from being dislodged when forklift operators make mistakes.
Coatings	Powder Coating	Rust-resistant, Orange color for easy identification in dark warehouses.
Maximum deflection	1/250 to 1/300 of the length	Safer than market standards (1/200), ensuring the rack does not deform.

2.1 Shape & material

Beams usually have an H-beam shape or a sturdy box bar, suitable for loads from 800 kg to 6000 kg/floor depending on the type of shelf.
Standard materials used: CT3 or Japanese JIS steel, thickness ranges from 1.5 mm – 2.2 mm, coated with European standard powder coating to resist oxidation and rust.

2.2 Standard Dimensions

Common beam sizes range from 40×80 mm to 50×150 mm, while the length is usually = 2 pallets + 30–40 cm of clearance for convenient loading and unloading of goods.
The length of the bore is usually equal to the size of a pallet × 2 plus 30–35 cm, for example, a pallet of 120×120 cm is about 270 cm long.

2.3 Connection Mechanism

The beam attaches to the pillar via a hook-in without bolts, making it easy to adjust the height as needed.
The system also uses support bars (C43, C50) to maintain the beam and increase the bearing capacity of each floor.

2.4 Struts and guards

Horizontal and diagonal tie bars help link the column frames into a solid system.
Column guards or protective barriers help minimize damage from impact from forklifts.

3. Calculating load capacity & Selecting Beam bar length according to technical standards

Many rack collapse incidents occur due to misunderstanding of “Permissible Load”. At Long Quyen, we apply the uniformly distributed load (UDL) standard to ensure absolute safety.

To choose the right Beam bar for your warehouse, follow these 3 steps:

Step 1: Determine the specifications of the goods

First, you need to know the specifications of the Pallet goods:

Weight of 1 Pallet (Including goods): Example 1,000 kg.
Pallet dimensions (Width x Depth): Example 1,000mm x 1,200mm.
Number of Pallets per level: Usually 2 or 3 pallets.

Step 2: Calculate Beam bar length (L)

The distance between pallets and between pallets and column frames must ensure a safety clearance of 75mm – 100mm for easy forklift operation.

Beam length formula: L = (Pallet Width x Quantity) + (Clearance x Number of gaps)

Example: You need to place 2 Pallets (Width 1,000mm) on 1 level.

L = (1,000 x 2) + (100 x 3 gaps) = 2,300mm.
👉 Choice: Choose standard Beam length of 2,300mm or 2,700mm (if you want more space).

Step 3: Check permissible deflection (Deflection Limit)

This is the most important indicator distinguishing quality products from floating goods. Under maximum load, the Beam bar will slightly bend down (elastic deflection).

Common standard: 1/200 of the length (L/200).
Long Quyen standard: We design with a high safety factor with deflection 1/250 or 1/300.
- Example: With a Beam length of 2,700mm, the maximum permissible deflection is only: 2700 / 250 = 10.8mm. If the deflection exceeds this number, the Beam is overloaded or of poor quality.

⚠️ IMPORTANT WARNING ABOUT UDL

The load indicated on the Beam bar (e.g., 2000kg/level) is Uniformly Distributed Load.

✅ CORRECT: Place 2 pallets (each pallet 1000kg) evenly on the Beam bar.
❌ WRONG: Place a 2000kg machine block in the middle of the Beam bar (Concentrated load point). This will break the Beam immediately!

4. Role & benefits of Beam bar in pallet racks

4.1 Main load distribution

When the pallet is loaded, the main beam bears the direct load — so choosing the right beam helps ensure the safety of the entire racking system.

4.2 Optimize storage space

With long beams and high load, the system can arrange multiple shelves, increasing the storage capacity without much space.
For example, 3-tier pallet racks help create up to 4 shelves for goods, which saves significant space.

4.3 Flexible assembly – adjustment

The hook-in mechanism allows for quick adjustment of the beam to the desired height without the need for bolts.
The spacing between the floors is easy to adjust to suit a variety of pallets and storage needs.

4.4 High durability & longevity

Made from standard steel, coated with powder coating, the beam is resistant to corrosion and high loads in the long term.

5. Types of Beam bars in pallet racks

5.1 Single-level Beam (1 beam)

Often used in 1-tier pallet racks with beams, creating 2 storage floors (1 under the floor + 1 on the beam) — the initial cost-saving solution, suitable for small premises but not optimizing the storage area.

5.2 Beam for 2 – 3 – 4 levels

The 3-tier beam pallet rack has a thick beam design and high load capacity, which is commonly used in large industrial warehouses.
Typical dimensions (length × width × height) and load capacity, for example: L2000 × W1000 × H6000 mm, load 1000 kg/floor, price from 2.2 – 6 million VND/head set (reference).

5.3 Beam system for special industrial warehouses

Selective, Double-Deep, Drive-In, VNA shelves… all use high-bearing beams, customize the floor spacing, forklift walkway, suitable for the height and high storage density requirements.

6. Disadvantages & points to note about Beam bars in pallet racks

Problem	Detail
Initial investment	Beams and medium/heavy-duty racking systems cost more than traditional V-hole or wood racking.
No rampant mounting adjustment	The beam is heavy, it is necessary to determine the floor height before installation to avoid incorrect installation and waste of time to disassemble.
Requires a flat warehouse floor	Uneven floors can cause beam misalignment, misalignment, and reduced load capacity.
Layout design needs to be accurate	It is necessary to correctly calculate the pallet size, cargo height, aisle forklift to choose the right beam; It is easy to have problems if the wrong parameter is selected.

7. Advice on choosing suitable Beam bars for pallet racks

7.1 Determine pallet type & load capacity of Beam bars for pallet racks

If the standard size pallet is 1200×1200 mm, choose a beam length of ~2700 mm.
Estimate pallet + cargo load to select the right size beam such as H40×80 (load ~1000 kg), H50×150 (load up to 2000–3000 kg)/

7.2 Check warehouse height & desired number of levels

Warehouse heights of 3–6 m are usually fitted with 2–4 pallet racks.
Warehouses with a height of 6 m+ can choose the right beam for high-rise cage support.

7.3 Consider forklifts & aisles

Forklifts typically need a 2800–3600 mm clearance between rows of shelves.
The beam needs to be designed so that the pallet is easily accessible, without touching the pillars.

7.4 Choose a reputable supplier

Choose a direct manufacturer, have a standard production process, full CT3, JIS, powder coating documents, support free layout drawings, clear warranty such as 1-5 years depending on the unit.
