What is a warehouse? Our definition

A warehouse is a facility that, along with storage racks, handling equipment and personnel and management resources, allows us to control the differences between the incoming flow of goods (received from suppliers, production centres, etc.) and the outgoing flow of goods (goods being sent to production, sales, etc.). Usually, these flows are not coordinated, and this is one of the reasons why it is important to have storage facilities.

Types of warehouses

At times, the business activity of a company requires one or more types of storage facilities: one for raw materials, one for semi-finished products, one for finished products, etc. All of these have to be arranged on the basis of their specific operational needs, and in accordance with the restrictions and potential of each location and its surroundings.

The best way to classify the different types of warehouses currently available is to group them according to their common features:

  • According to the nature of the product there are warehouses specialising in coils, flammable products, profiles, small materials, spare parts and perishables and even warehouses that are for general use, among others.
  • The building itself can also be a criterion for its classification. Buildings can be classified as open air warehouses, industrial buildings, basements, depots, cold storage chambers, clad-rack warehouses (the racks form part of the building's constructive system), etc.
  • According to the flow of materials, installations can be grouped into those used for raw materials, components or semi-finished products, finished products, intermediate warehouses, for warehousing, for distribution, etc.
  • In terms of location, warehouses can be central, regional, or for transit.
  • According to the extent of their mechanisation, they can be manual, standard, or automated.


What happens in a warehouse?

The main tasks performed in a warehouse are:

  1. Receipt of goods
  2. Verification of those goods
  3. In-house transport (between different parts of the warehouse)
  4. Storage and safe-keeping of items
  5. Preparation of orders and the consolidation of loads
  6. Dispatch of goods
  7. General management and processing of information related to the stock, workflows, demand, etc.


What elements are involved in a warehouse?

A number of factors must be taken into account when planning a facility. The most important of these are the products to be stored, the flow of materials or goods, the space available to house them, the storage equipment—such as racks and handling equipment—, the human factor (personnel), and the company’s management system and policies.

Based on the above, a series of information must be collected. This information, which is stipulated below, will in turn influence the various aspects of the facility and must be taken into account during its development.


What are the different parts of a warehouse?

The simplest warehouses normally have access doors, an open area for maneuvering and verification, a storage area where the goods are located, a managent office for controlling operations, and toilets and changing rooms for personnel.

Starting with the simplest configuration, other areas can be added. This includes areas for reception, packaging and consolidation, dispatch, recharging forklift batteries, as well as loading docks. For example:

In turn, a warehouse can be divided into sectors according to the product being handled or the work operations. The following diagram illustrates an example of this type of organisation:

1. Office and customer services.

2. Loading and unloading docks.

3. Reception and verification.

4. Dispatch.

5. Warehouse for high turnover or over-sized product.

6. High turnover picking off pallets.

7. Warehouse for odd-shaped products.

8. Warehouse for medium turnover components.

9. Warehouse for high turnover components.

10. Warehouse for low turnover components.

11. Warehouse for high-value products.

12. Packaging and consolidation.


How a warehouse is organized into areas.

The space assigned to each area must be suitable, given the size of the land or building, the desired capacity, the operations that need to be performed, the required personnel and resources, the flow of materials, and the growth potential.

In any event, the customisation of the project and the design of areas within the installation will be determined by an in-depth study of the company’s needs—through the previously mentioned questions—and the supplier’s experience in implementing logistics and storage solutions.

The entire building—its shape, contents, and access points—must be in keeping with the specific needs of the customer. Opportunities for growth must also be taken into account. Building a warehouse that only meets current requirements and leaves no room for expansion would be a mistake, unless it is a temporary installation or one that will not experience growth.
