Outdoor Storage Boxes: A Buyer’s Guide

Before investing in an outdoor storage box, ensure you understand the factors to consider. If you don’t, you may end up buying the wrong product. Explore this buying guide to learn more about these considerations. 

What to Look For When Selecting an Outdoor Storage Box

Material

An outdoor box means that you will be exposing it to different external elements. This includes heat, rain, mold, and wind. If you want the box to survive against these factors, make sure it features a strong material. For instance, polyresin is an excellent material to combat external weather conditions. It won’t peel or fade easily and it will also keep the contents dry. 

Some outdoor storage boxes are made of wood. While it is a durable and strong material, low-quality wood often swells or gets discolored in water. If you want your box to serve you for an extended period, evaluate the pros and cons of the material used before choosing it. 

Design

The design of your storage box is also an essential factor, especially when you will be placing it outdoors. Most boxes come with lockable lids, increasing the safety of the products stored inside. Certain boxes also have an excellent ventilation system to keep the items dry. 

When choosing a box with a good design, also consider its construction and the lid mechanism. For example, some box lids lack quality hinges, and opening or closing them is a hassle. 

Also, don’t forget to evaluate the exterior. A good-looking outdoor storage box blends well with the rest of the furniture and can be used as an additional seating option. 

Internal and weight capacity

Before buying a box, ask yourself about the internal capacity you expect it to have. A low internal capacity means you can’t store many items at a time. Alternatively, a large internal capacity is perfect for all your tools, children’s pool toys, and furniture cushions. 

If you want to use the box as a seating option on your patio, always check its weight capacity. You don’t want to use it as a seat and break it after exerting more pressure than it can bear. 

Size

Invest in a box that doesn’t look too big or too small in your outdoor space. Buying a product with an ideal size helps ensure that it fits well and doesn’t take up unnecessary space. 

Other features

The perfect outdoor storage box should have a solid lid to keep the water away. It should also contain hinges that won’t disrupt its opening and closing mechanism. Certain boxes feature handles that make it easy to move them from one spot to another. 

A box that comes in various colors is an excellent option to consider. This way, you can choose easily and measure one color against the other. 

Price

Finally, invest in an outdoor storage box that provides value for money. Don’t hesitate to evaluate various options before making a choice. A box that meets your capacity and design requirements at a reasonable price is worth considering.
