- A larger Protect-a-Box size is also available if you need more storage capacity
Construction
Built from premium PVC coated galvanised steel panels, this metal storage box is engineered for long-term performance. The robust construction keeps its shape and resists weathering, protecting your tools and equipment from the elements. The heavy-duty metal floor stops ground moisture getting in, while stainless-steel fixings remove any risk of rust at the joints.
Treatment & Guarantee
The Trimetals Protect-a-Box comes with an impressive 25 year panel warranty, reflecting the manufacturer’s confidence in this metal storage box. The PVC coated galvanised steel construction needs no painting or treating, saving time and money over its lifespan, and being fire-resistant adds an extra layer of safety for stored items.
Doors & Windows / Security
Access is through a top-opening lid fitted with gas struts, so it opens smoothly and safely rather than slamming shut. A double-bolted key lock provides strong security, and the box is designed to be bolted onto a hard base, which prevents it being lifted or carried away.
Assembly Information
Although straightforward to put together, comprehensive step by step instructions are included to guide you through the process. Most people manage assembly without specialist tools or expertise.

Free delivery is available to most UK addresses, making this metal storage box an accessible investment for the garden. Check your postcode at checkout to confirm delivery eligibility.
Optional Upgrades
The Protect-a-Box is available in six colours, including this anthracite finish, and in a larger size if you need more capacity. No separate base or accessory kit is required, as the box is designed to be bolted straight onto an existing hard surface.
