Outdoor plastic storage cabinets are a popular choice for organizing and protecting items outside of the home. They are durable, weather-resistant, and available in a wide range of sizes and styles. But what exactly are these outdoor cabinets made from? Here is an overview of the common materials used to construct outdoor plastic storage cabinets.
Polyethylene
Polyethylene, sometimes shortened to poly, is one of the most common plastics used to make outdoor storage cabinets. Polyethylene is a lightweight and durable plastic that is resistant to weathering and corrosion. It provides good impact resistance even in cold temperatures. Polyethylene cabinets will not rust, peel, or deteriorate when exposed to the elements. This material is easy to mold into storage containers of various shapes and sizes. Polyethylene’s natural color is opaque white, but it can be tinted in many shades with pigments. It is an affordable option for manufacturers and consumers alike. Polyethylene outdoor storage units are lightweight, making them easy to move and transport. It is also recyclable, giving it eco-friendly appeal.
Polypropylene
Polypropylene (PP) is another popular plastic used in outdoor cabinets. It shares many of the same properties as polyethylene but has higher heat resistance. Polypropylene can withstand temperatures up to 212 degrees Fahrenheit without warping or melting. It has high tensile strength, making it very durable and resilient. Polypropylene is naturally translucent with a waxy texture. Manufacturers often add colorants to polypropylene to create storage containers in various colors. Polypropylene is lightweight, weather-resistant, and recyclable. It is easy to mold into a variety of cabinet and shed designs. The material is flexible and will bounce back to shape after impacts. Polypropylene outdoor storage is typically more expensive than polyethylene options.
High-Density Polyethylene
High-density polyethylene (HDPE) is a tougher, heavier plastic that is sometimes used in higher-end outdoor cabinets. It is highly impact-resistant and more rigid than standard polyethylene. HDPE cabinets are extremely durable against weathering and corrosion. They retain their color well even with long-term sun exposure. HDPE is more expensive than regular polyethylene and can be harder to mold and work with. But its dense molecular structure makes it very strong for items that will hold heavy contents outside. High-density polyethylene cabinets may have thicker walls than competitors. The material is fully recyclable.
Reinforced Plastics
Some outdoor storage cabinets use reinforced plastic composites. This means they are made from plastic that has been strengthened with other materials. For example, glass fibers are commonly added to boost the tensile strength and rigidity of plastic resin. This creates a very stiff, robust material capable of supporting heavy loads without flexing. Reinforced plastics resist bending and warping better than standard polyethylene or polypropylene. They are also more scratch-resistant. Reinforced plastic outdoor cabinets are more expensive but provide enhanced protection for contents.
Metals & Alloys
While most typical outdoor storage units are plastic, some are constructed from metals or metal alloys. Steel is occasionally used, providing excellent structural integrity. However, steel is prone to rusting and corrosion if not specially treated. Stainless steel and aluminum alloys are more commonly used. Stainless steel resists rust and withstands weathering. Aluminum is a lightweight but strong metal that holds up well outside. Metal outdoor cabinets often have higher price tags than their plastic counterparts. But they offer added security and sturdiness for protecting certain possessions.
Wood Composites
Some outdoor storage cabinets combine plastic resins with wood fibers, chips, or sawdust. This produces a durable, weather-resistant composite material with the look and feel of natural wood. Composite wood plastics won’t rot, splinter, or warp like solid wood. Manufacturers mold them into attractive cabinetry that does not require painting or staining for outdoor use. These wood plastic composites are popular for sheds, tool storage, and any cabinets that should tie into outdoor home aesthetics. They provide both beauty and rugged durability at a moderate cost.
Factors Affecting Durability
When choosing an outdoor plastic storage cabinet, durability depends on more than just the core material. Factors like wall thickness, construction quality, hinges, and closing mechanisms also impact longevity. Look for cabinets with thick, uniformly molded walls without gaps or seams that water could penetrate. Hinges should be made from non-rusting metal alloys or plastic. Ensure doors seal tightly with quality latches or locks. Selecting cabinets backed by warranties can give assurance they will endure outdoor elements for years of use. Properly caring for any outdoor cabinet according to manufacturer guidelines will help maximize lifespan.
Key Benefits of Plastic Outdoor Cabinets

Plastic resin cabinetry provides outdoor organization and security without the maintenance of wood materials. Knowing the main polymers used helps select storage tailored to your needs and climate. From polyethylene tool sheds to reinforced composite cabinets, plastic gives versatility in safeguarding your outdoor possessions. Carefully constructed with quality materials, your outdoor plastic cabinet can provide years of reliable service through any weather.
Frequently Asked Questions About Outdoor Plastic Storage Cabinets
What are the most durable plastics for outdoor cabinets?
High-density polyethylene (HDPE) and reinforced plastic composites are very durable options for outdoor cabinet construction. They withstand weathering and retain strength for years.
Do plastic outdoor cabinets need to be sealed or painted?
Plastic cabinets do not require additional sealants or paints. Their molded constructions are uniformly waterproof and colorfast as they come from the factory.
Will plastic cabinets fade in sunlight over time?
Some fading may occur after prolonged sun exposure, but plastic outdoor cabinets are formulated to resist ultraviolet damage. They retain their color much better than wood furnishings.
Can you put plastic outdoor cabinets directly on the ground?
Yes, plastic resin cabinetry is designed for ground contact and will not degrade or leach chemicals like treated wood might. Proper drainage under the cabinet is recommended.
What is the benefit of wood composite outdoor cabinets?
Wood plastic composite cabinets offer the appearance and workability of natural wood without the downsides like rotting. They are an attractive and durable outdoor storage option.
Are plastic tool sheds and cabinets safe from pests?
Plastic’s non-porous, uniform surface leaves nowhere for pests to bite, burrow, or nest. No need for exterminators like you might with wood sheds. Rodents will have a hard time gnawing through thick plastic.
Are plastic outdoor cabinets covered by warranties?
Many manufacturers offer limited warranties ranging from 1-10 years. Check warranty terms for details of what defects or damages are covered. Proper care will help your cabinet meet its lifespan potential.
Final Thoughts
Outdoor plastic storage cabinets made from polymers like polyethylene are the most popular choice for their weather resistance, light weight, and affordable cost. High-density plastics and reinforced composites offer premium durability for more demanding storage needs. Cabinet construction also impacts longevity. When shopping, look for uniformly molded pieces with quality hinges and closures to serve your outdoor organization needs through all seasons.
