Quality Steel Framed Buildings

S.I.S. (Steel Interlock Sheds) supply sheds, garages, horse barns, American barns, stables, farm buildings, aircraft hangars and light commercial buildings. Quickly assembled compared to other conventional steel building construction methods,  will save time on site and labour costs.

The Framing System

The unique S.I.S. steel framing system means we can quickly  construct steel sheds, garages, storage buildings and warehouses with spans up to 16 meters. Our product combines the strength of steel with the patented VersaTube ™ “Slip-Fit” design.

Expandability Of Our Sheds

All our buildings are expandable so you can make your structure larger as circumstances permit.

Choices And Options 

S.I.S. sheds and garages are available in a wide range of colors, lengths, widths and heights utilizing 75×50 and 100×50 RHS hollow section framing. Other options include  windows and ranch sliders, roller, sectional,  and PA doors, clearlites and building paper. The rectangular hollow section ( RHS) also extremely simplifies the interior lining and fit out process of your structure.

Shed Strength and  Durability

Another key feature is the mandrel bent side posts and peaks. By supporting the tube with a steel mandrel during the bending process, the side posts and peaks are able to maintain maximum tube strength.  Our frames have the patented Versatube(tm) “Triple -Coat” process applied to the steel for maximum corrosive resistance and come with a full 20 year guarantee. The NZ cladding comes with a 15 year warranty specific to the site location.
