Roof Types
This apex metal shed features a strong ribbed roof design that maximises headroom and provides excellent weather protection. Ventilation slots along the roof peak and eaves support proper air circulation, preventing condensation and dampness inside the shed. The apex configuration sheds rainwater efficiently away from the structure.
Dimensions
Internal dimensions: 3.03m x 2.98m (10′ x 10′)
The generous floor area provides ample space for storing larger items such as lawnmowers, garden furniture, bicycles and power tools. High gables deliver extra headroom, making it comfortable to move around inside.
Construction
Built in the UK from high-tensile strength, hot-dipped galvanised steel with seven layers of protection against corrosion. The wall panels feature folded edges for added safety, and internal wall bracing provides extra structural strength. The ribbed panel design adds rigidity to the entire frame, ensuring the shed remains sturdy throughout its lifespan.
Unlike wooden garden sheds, this metal construction prevents peeling, warping, blistering and rot. The steel won’t become brittle or break in cold weather.
Treatment & Guarantee
The anthracite grey finish is applied to premium galvanised steel, offering exceptional corrosion resistance. This metal shed comes with an excellent 15-year anti-rust manufacturer’s guarantee, protecting your investment and giving complete peace of mind. The weather-resistant design requires virtually no maintenance, no painting, treating or sealing needed.
Doors & Windows
Sliding double doors make it easy to move equipment, tools and bikes in and out of the shed. The doors feature integrated weather seals to keep wind and rain out effectively. Anti-tamper screws secure the door handles, and there’s space to install a padlock (not included) for added security. A strong entry/exit ramp is included to facilitate loading and unloading.
Assembly Information
The shed is supplied flat-packed for delivery. Assembly is required and involves bolting panels together and securing the structure to your base using the included anchor kit. We recommend at least two people for assembly, and allow a full day for installation.
Delivery Information
Free delivery is available to the majority of UK postcodes. The shed has been designed without a floor, so it must be installed on a level or paved base (concrete, paving slabs or similar). A free anchor kit is included to help secure the shed firmly to your base, preventing movement in high winds.
Optional Upgrades
The Yardmaster range includes various sizes and colour options. If you’re considering plastic sheds or log cabins as alternatives, we offer a comprehensive selection of garden storage solutions to suit every requirement.
Frequently Asked Questions
Do I need to treat the metal shed?
No. The hot-dipped galvanised steel with seven layers of protection is maintenance-free and requires no treating or painting.
Can I install this on grass?
No. The shed must be installed on a level, solid base such as concrete or paving slabs. An uneven or grassy base will reduce stability and longevity.
Is the floor included?
No. The shed is designed to sit on your prepared base. This design choice reduces cost and allows flexibility in base preparation.
