The choice you make in materials will determine not only how much weight your cabinet can hold, but also how long you can expect your cabinet to withstand the test of time. Let's take a look at the most common choices.
Steel storage cabinets typically have incredible shelving weight capacity, with some models being able to hold over 300 lbs spread across their shelves. As strong as steel shelving can be, it can fall victim to rust over time. Luckily, a regular application of rust prevention aerosol sprays or solutions can prevent this.
Steel cabinets also tend to lack a variety of options when it comes to finishes and style. Most cabinets made of steel will be finished in a simple black or silver finish, with more emphasis placed on function than style.
Plastic storage cabinets are sturdier than you're probably assuming. Many modern models have a shelf weight capacity of over 100 lbs and come with a variety of styles and combination options. Plastic has the additional benefit of being naturally resistant to water and can withstand a wide range of temperature fluctuation.
Lower quality plastic shelving can become brittle in cold weather, so you'll have to be mindful to verify the quality of your cabinets with the manufacturer beforehand. You can also consider using the search function to quickly sift through online reviews to double-check for this specific issue.
Unlike steel and plastic, wood has a number of "natural enemies" that already exist within your home, namely, humidity and temperature fluctuations. Manufactured wood can be especially vulnerable to these things, given the way it is typically constructed.
Manufactured wood panels are normally made from plywood or MDF cores, which are then covered with veneers for appearance. Manufactured wood cabinets offer more than both plastic and steel as far as aesthetic options go.
Manufactured wood can be finished with natural wood grains, hardwood veneers or simple black, white and gray tones, which makes them a good option if you have a décor you're hoping to maintain.
