Of all the methods of protecting mild steel against corrosion, hot-dip zinc coating is the most common. A zinc coating protects steel in two ways:
It acts as a physical barrier between a potentially corrosive environment and the steel base.
The zinc coating gives galvanic or sacrificial protection at cut edges and at scratches.
In dry and unpolluted environments, steels with a coating of 19 microns of Galvanite hot-dip have a expected design life of 20-50 years.
Galvanite complies with European standards and is also available to other national and international standards by agreement with Corus. Contact us for more information.

With a little effort these doors open and close in a smooth movement. Secured with strong locks each side of the door, these doors offer the garage owner peace of mind.

We recommend a Concrete Base with a rebate for all our units. The reason for this rebate is that the floor level is approx 50mm higher on the inside than the outside base height, this ensures the floor is fully secured and sealed against wind and rain.
We will supply you with a fully-detailed base drawing for the shed you order. This base drawing is essential in order to have the base the correct size for your shed or we have a subcontractor that can do all the base preparation for you.
A concrete surface may look dry, but the slab can still contain sufficient moisture to cause problems when covered. The amount of concrete moisture can be considerable. In practical terms, several pounds of water must evaporate from every square foot of concrete for the slab to be considered adequately dry for floor finishes. The industrial rule of thumb for estimating the drying time necessary for concrete floors to reach acceptable moisture content is 1 month of drying for each inch of concrete thickness (1mm per day). So to help the drying time in your new unit you should take the following steps:
These units have to be adequately heated to achieve ideal storage conditions for some products.
