What Defines a Metal Shed?

A Metal Shed is a popular garden storage solution, known for its durability, security, and low maintenance. These sheds are typically made from steel or aluminium, making them highly resistant to weather conditions, pests, and fire. Metal sheds are ideal for storing tools, garden equipment, and outdoor furniture, but not all metal sheds are created equal. The type of metal used, the shed’s design, and specific features all contribute to its longevity and functionality. Here’s what you should look for when considering a metal shed for your garden.

Common Types of Metal Used in Garden Sheds

1. Galvanised Steel
Galvanised steel is the most commonly used metal in garden sheds. It’s coated with a layer of zinc to prevent rusting and corrosion, making it highly durable and suitable for outdoor use. Best for sheds exposed to rain, snow, or humidity as galvanised steel can withstand harsh conditions while retaining its structural integrity. Look out for cheaper sheds with thin steel panels (less than 0.25mm thick) that are more prone to denting.

2. Powder-Coated Steel
Powder-coated steel is galvanised steel with an additional powder coating applied to the surface. This adds extra protection and enhances the shed’s appearance with a smooth, often coloured finish. Best for homeowners looking for a long-lasting, low-maintenance shed that balances durability and aesthetics. Look out for low-quality powder coatings that chip or wear off, potentially leading to rust if the steel is exposed.

3. Aluminium
Aluminium does not rust, making it an excellent choice for wet environments or coastal areas where saltwater can accelerate corrosion in other metals. Best for high humidity or coastal areas where saltwater corrosion is a concern. Look out for aluminium sheds that are typically less strong than steel ones. Ensure they have reinforced frames to withstand strong winds or heavy snow.

What to Look for in a Metal Shed

1. Panel Thickness
The thickness of the metal panels determines the shed’s durability and resistance to damage. Ideally, choose sheds with steel panels at least 0.25mm to 0.35mm thick for better strength and longevity.

2. Anti-Corrosion Treatments
Metal sheds are prone to rust, especially in high moisture areas. Look for sheds that are galvanised or powder-coated to prevent rust and maintain the shed’s appearance over time.

3. Ventilation
Proper ventilation helps prevent condensation inside the shed, reducing the risk of mould, mildew, and rust on stored items. Ensure the shed has built-in ventilation grilles or vents to keep the interior dry.

4. Roof Design
The roof design impacts how well the shed handles rainwater runoff and snow loads. Apex roofs are ideal as they allow water and snow to run off easily, providing more headroom. Pent roofs are also effective for smaller sheds if positioned against a wall or fence.

5. Foundation and Flooring
Metal sheds are typically sold without flooring, so it’s important to have a solid base such as a concrete platform, patio slabs, or raised decking to keep it elevated and protect it from ground moisture.

6. Security Features
Metal sheds are often chosen for their security. Choose sheds with reinforced doors, hinges, and a lockable handle or integrated locking system for added protection.

7. Assembly and Maintenance
Opt for metal sheds that come with clear assembly instructions and pre-drilled holes. Sheds with sliding panels or snap-together designs are easier to assemble. Look for low-maintenance options like galvanised or powder-coated sheds that require minimal upkeep.

What to Look Out For (Potential Pitfalls)

1. Thin Metal Panels
Sheds with very thin metal panels (less than 0.25mm) may not be durable for long-term use. These panels are more prone to denting, which can weaken the structure over time.

2. Poor Anti-Corrosion Coating
Avoid sheds with minimal rust protection or poorly applied coatings. Sheds with incomplete galvanisation or powder coatings that chip or flake can rust, especially in rainy or coastal environments.

3. Lack of Ventilation
Without proper ventilation, metal sheds can suffer from condensation, leading to damage to the shed’s contents and internal rusting.

4. Inadequate Flooring Options
Metal sheds often don’t include a floor, so placing the shed directly on grass or soil can cause moisture buildup. Make sure the shed has a sturdy, elevated base to prevent contact with moisture.

5. Difficult Assembly
Some metal sheds can be difficult to assemble. Look for models with clear instructions and well-fitting panels to avoid issues during the building process.

Why Metal Sheds Make an Excellent Storage Choice

When selecting a Metal Shed, focus on the quality of the metal, such as galvanised or powder-coated steel for durability and weather resistance, or aluminium for rust-proof protection in high-moisture areas. Key factors include thicker panels (at least 0.25mm), proper ventilation, and a solid foundation to ensure the shed remains sturdy and functional. Be cautious of sheds with thin panels, inadequate anti-corrosion treatments, and poor ventilation, as these can compromise the shed’s longevity. A well-constructed metal shed can offer long-lasting protection for your tools, equipment, and garden supplies, making it a valuable addition to your outdoor space.
