Structured To Work For Agribusiness

With over 20 years of experience designing & building custom fabricated steel structures for agribusiness, you can be sure you’ll get a shed that is structured to work.

Our Shed Options


TechSpan’s engineering experience starts underground. All designs include foundation details which can be customised to suit your location and soil. Our buildings are held down with engineered cast-in hold down bolts.

Watch out for low cost alternatives that use light weight plates and brackets that are only fixed down with low strength masonry anchors. No short cuts should be taken in this critical area.


All columns on TechSpan buildings are constructed using universal beam. These are of solid one piece construction from top to bottom.

These are painted using our signature triple coat protection system zinc-rich primer long lasting shield against corrosion. For exceptional protection, columns can be hot dip galvanized.

Personnel Access Doors

Most larger buildings require one or more PA doors as the larger doors normally cannot be opened from the outside. For this reason it is often useful to locate your PA doors near your larger doors.

Depending on the size of your building, Council Regulations could require you to have further PA doors around the perimeter of your building for use as fire exits.


Insulation is often an area that is passed over in shed design. The benefits of working through this are long lasting and rewarding.

Options include Anticon or Sisalation, Roof Insulation Blanket and Air-cell. Anticon is almost essential for most buildings as nobody really likes condensation dripping everywhere on those cooler mornings. 

The roof blanket offers further benefits – cooler in summer and warmer in winter. It is truly surprising what difference it actually makes. Please consider these requirements carefully.

Air-cell in is a premium insulation product which offers superior insulation qualities while maintaining a very low profile of just 8mm thick. It looks like foil backed “Bubble Wrap”.


Natural roof ventilation serves two very important functions on your building. It provides temperature relief by allowing the hot air that gathers up in the ridge of your building to escape, creating a convection current thus drawing cooler air in through the lower openings. Provision can be made to have these seasonally adjustable.

The other benefit of roof ventilation is it allows unwanted fumes to escape from the building. Maybe the old tractor is not running like it used to, or perhaps those welding fumes are a bit overpowering. It is surprising what results can be achieved with natural ventilation.

The two most popular options are Ridge Vents and “Whirly birds”. The TechSpan team can help with your requirements.


Skylights are a great way to take advantage of natural sunlight to light your building. The team at TechSpan has many ideas in this area for both roof and walls. Investment in this area will pay itself off many times by reducing the ever-rising cost of electricity used.
