The basic composition of the pallet rack is mainly composed of basic parts such as uprights and beams and other optional accessories such as upright protectors, supporting bar, barriers, and platform (steel plates or wood panels). The upright is assembled by horizontal bracing and diagonal bracing. Upright and beams are the main support components of the rack. The maximum load of each layer can reach to 5 tons. The length of the beam is 1 to 4 meters, which is mainly determined by the size of the pallet of the rack. The uprights are punched with circular holes and other shapes of hanging holes, which are used to assemble, support and connect other stressed members to form a unique structural system with porous uprights as vertical supports. The beam and the uprights are connected by a plug in type, and the beam is embedded into the hanging hole of the upright by the hook at the end to form a structure.

In warehouse cases, the length of the beam is selected in advance according to the usage of the racking. Therefore, the beam model is usually selected by calculating the maximum load of the beam according to the load condition of the racking.  The load bearing capacity of the beam refers to the size of the cargo load carried by the beam. In addition, since the material of the beam is generally structural steel, the weight is relatively heavy, so the influence of the weight of the beam needs to be considered in the calculation process to uniformly distribute the load. The force of the beam is related to the placement of the goods in the actual working state, so the form of the force is more complicated, but generally it can be distributed in two basic types: uniform load and multi point concentrated load. In actual use, it is mostly a combination of two forms. The allowable load of the beam is determined. The beam and the column of the combined rack are connected by plug in connection. The beam is embedded into the hanging hole of the column by the hook at the end. On the one hand, this connection method allows the beam to rotate around the axis before the force is applied, and on the other hand, it requires that the end of the beam can transmit the moment of the load on the beam on the column. Therefore, the two ends of the beam cannot be simplified as a simple hinge. If the supporting end or one end is fixed, the influence of the partial embedding of the beam and upright semi rigid connection node should be considered when calculating the strength and deflection of the beam.

2. Q: Where is your factory located?

A: Our factory is located in Guangzhou, a city near Baiyun International Airport.

3. Q: What is your delivery time?

A: For standard size models, we have plenty of material in stock, less than 500pcs, 3-7 day is ok;

For customized models, the delivery date depends on the quantity. In generally, it is 7-15 days. We can finish production in 15 days under 332 CBM, 9 containers.

4. Q: What is the term of payment?

A: 40% of deposit , and balance will be cleared by T/T before delivery.

5. Q: What is the trade term?

A: In generally, we will use EXW or FOB. Other terms can be negotiated.

6. Q: Do you have minimum order quantity limitation?

A: We don’t have MOQ limitation. But if you don’t have other goods to share the container and the quantity is less than 10pcs, we would sincerely recommend you buy at the local market. Because the international freight will be expensive.

7. Q: Are samples available?

A: Yes, samples are available at any time. But due to the big size, we would like to suggest you to check some raw material if you just want to check the quality. And we can offer you the raw material in free, you just need to be response for the freight.

If you have container needs to be shipped together recently, then you can buy any quantity you want.

8.Q: What if you encounter problems during installation?

A: We will provide detailed install instruction for every type of shelf. If needed, we can also ask engineers to teach you by phone, face-time or video.

9. Q: Could you produce the goods in OEM and ODM design?

A: Sure, we have very rich experience in customizing shelves.

10. Q: What are main rack and add on rack?

A: The difference between these two kinds of racks is upright. Main rack is the start rack with 2 uprights and add on rack is the continue rack with only 1 upright.

11. Q: What is your packing?

  A: Generally, storage rack are flat packed by air bubble film. Other packing like wooden box are available to clients’ requirement.

12. Q: What if we can’t install it or we don’t have installers?

A: For the racking mezzanine floor case or big project, if needed, we can offer our technical staff to guide the installation job. Moreover, we have professional installation team to deal with the installation work. So, please do not worry about that.

13. Q: What is the warranty?

A: From 3 years to 5 years.

14. Q: Can we pay by Credit card or Alibaba platform?

A: Yes, you can. And TT is welcome.

15. Q: which loading port is close to you?

A: Nansha or Huangpu. They are in Guangzhou. If your forwarder is in Foshan or Shenzhen, we can deliver them to their warehouse too.
