Treat your car and yourself with an impressive metal garage from elbec. Produced using hot dipped galvanised steel throughout, these large metal sheds will not only provide a secure place for your car, they will also plenty of storage room for your gardening equipment and tools. Sapphire Olympian Garages are both easy to assemble and easy to maintain, meaning you will find them a real time saver compared to other options for protecting your car.

There many reasons why the Sapphire Olympian is one of the best metal garages on the market today including one of the longest guarantees around - a 10 Year No Rust Perforation Guarantee which shows how confident they are about their metal sheds. The reason that Emerald are able to offer such a terrific guarantee lies in the fact that their sheds are made from hot dipped galvanised steel throughout, this means that the Sapphire metal sheds will not crack and will maintain their lasting good looks. This is not the case for other metals sheds on the market which only offer an inferior electro galvanized protection or part hot dipped galvanised steel, making them vulnerable to rust and unsuitable for coastal areas with their high salt atmosphere. 

The high quality of the Sapphire Olympian means that its good looks won't just last, they will last for a long time while requiring next to no maintenance. Simply give the shed an occasional wipedown to keep it clean and you will have a great looking shed for years to come!

You don't have to worry about receiving a flimsy or lightweight metal shed, our Sapphire range are taller and sturdier than almost all other 'thin clad' steel sheds. The door is secured by a padbolt, allowing the shed to be locked using a padlock (not included).

The gables are ventilated to allow consistent airflow throughout the shed and reduce the build up of condensation. This is an important feature to consider when purchasing a metal shed. These metal sheds come complete with a sturdy ramp which makes entry to and exit from the shed easy - even with wheel barrows or lawn mowers.
