About Techspan

Who owns Techspan?

TechSpan is a family partnership wholly owned by two brothers and their families. From our first building some 20 years ago we have been developing an ever-strengthening reputation for quality pre-engineered building solutions.

Management is supported by a skilled and motivated team. Each member of the team is selected because of their personal commitment to excellence and provided with constant training to further them in their chosen career.

Where is Techspan based

TechSpan is based in Armidale NSW. We have the advantage of being centrally located between Sydney and Brisbane allowing us to competitively source our materials from two national centers.

This location is conveniently placed to service both Northern NSW and Southern and Central QLD. Locations beyond this are still easily reached with our network of freight contacts.

Do you offer a warranty on your buildings?

Yes, we offer a 25-year warranty on our structures.

Shed Design

Why should I buy a structural steel building instead of Cold-formed purlin?

Structural steel is an intrinsically superior method of constructing large shed frames. It provides a stronger and more rigid structure that is able to span further. C – Purlins were designed for fixing roof cladding to trusses and we believe that is where they belong.

Many carport and garage manufacturers stretch their use to complete large span rafter members. At TechSpan we don’t feel safe offering these designs to you for larger buildings because we stand by our designs forever.

Do your designs have any certification?

To give you assurance and peace of mind about the strength and security of your investment we have all of our designs certified by a fully Independent nationally Registered Structural Engineer.

What do I need to do about council approvals?

Rural buildings less than 200m2 do not normally require council approval. For larger buildings, we provide you with a complete set of engineering drawings ready for submission to council. This simplifies the process of preparing the application.

During the approval process, we are there to answer any technical questions that may arise. Please contact your local council for specific advice.

What are the differences between Colourbond and Zincallume cladding?

Zincallume Steel is a Steel strip base with a coating of 45% Zinc and 55% Aluminum. This coating makes the steel more resistant to corrosion. Colourbond is pre-painted steel coil available in a range of colours.

It consists of a metallic coated steel base with a 3 coat paint finish applied to the outer face and a 2 coat finish to the inner face. Colourbond steel can be roll-formed, pressed or bent without any deterioration to the finish.

What do you use for Wall Bracing?

We use tensioned steel cables as bracing in our buildings as they provide strong lightweight adjustable means to stiffen the building.

What type of Hold-down Bolts are used on your buildings?

All of our buildings are fastened with footings 4x robust galvanized threaded rods per column. These are cast to the footings when the concrete is poured. Contrary to lighter purlin sheds, these are embedded up to a meter into the footing offering unparalleled hold-down and uplift restraint.

Can you build a building any size?

Our standard designs can span anywhere from 9m to 60m clear span. The length is virtually unrestricted. We do however have standard spans and bay spacings which can save you money.

Are your buildings “Shed Safe” accredited?

Shed Safe accreditation was set up in an effort to curb the ever-increasing group of purlin shed builders constructing non-compliant structures. TechSpan Building Systems use UB columns and welded web truss construction. This method of construction is fundamentally safer and stronger and does not require Shed Safe accreditation to prove its integrity.

When considering cladding thickness what do TCT and BMT mean?

The steel may be measured as BMT (Base Metal Thickness), which is entirely structural material. Some suppliers give measurements as TCT (Total Coated Thickness), which includes coatings, about 0.05mm of extra thickness. This means that a BMT of 0.42 and a TCT of 0.47 are describing the same thickness of base steel.

Make sure you know the difference as different suppliers describe materials using different terms.

Shed Production

What is included in your kits?

Our shed kit includes all the materials you require to build your shed. From the Cast in hold-down bolts in the footings to the rivets in the ridge cap, it is all included. A comprehensive list of provisions is itemised on your quotations document.

How quickly can I have my shed delivered?

Our standard lead time is approximately 6 weeks, from final approval. However, please feel free to talk to us if you have special requirements.

How do you arrange delivery?

Site delivery is included, as standard, in our quotations. However, if you would like to make your own arrangements you are more than welcome.

Shed Erection

Can I erect my shed myself?

Installation of a large structural steel shed is not for the faint-hearted (or the inexperienced). However, if you feel that you have what it takes, we do provide you with clear assembly drawings and are happy to talk you through the tricks of the trade.

Can you arrange installation for me?

Yes. We have teams of accredited installers who are experienced in getting the job done safely and on time. All our install teams have passed a rigid prequalification assessment to ensure the job result is to your complete satisfaction.

What IS included in your erection price?

Our comprehensive erection package includes the following:

  • Mark out concrete footings
  • Labour to locate and pour Hold down Bolts.
  • Erection of the steel structure
  • Crane and Access equipment
  • Installation of cladding, gutters and downpipes to ground level
  • Fit and test external doors
Do you install the slab as part of your contract?

No, we would not normally get involved with the concrete slab. We have found that it is more cost-effective for you to have this done by a local concreting contractor.

Are your sheds safe to erect?

Our Installers say that TechSpan buildings are the safest sheds they’ve ever built. The unique swing-down column design enables the entire roof structure to be assembled at ground level and lifted on completion.

This virtually eliminates the risk of working at heights and the cost of expensive access equipment.
