Our Process

Great Gates customise and oversee the manufacture of every gate we install, to make sure that you have the perfect solution!


Once you have contacted us, we will come to your site to establish what you require in more detail. We carefully consider all aspects of the job, by listening to what you expect and evaluate what can be delivered due to the site layout, geography and your preferences. We will then provide a competitive quotation for your appraisal.

Frame construction and materials

Black steel and then Hot Dip Galvanised: Better for corrosion resistance. Galvanised steel and either cold galvanised spray the welds before you paint by brush (wet paint) or spray or have powder coated (popular option)

Aluminium: We predominantly  powder coat the aluminium – best and popular option for corrosion resistance.

Stainless Steel: price on application ,  mainly selected for corrosion resistance and aesthetics.

Sliding gate frames mostly have a 100 x 50 x 3 bottom rail to accept the gate wheels inside the frame and to accept the drive rack for the automation.

We normally use 50 x 50 x 3 frames for our swing gates, with other sizes to design and price.

Pedestrian gate frames are usually 40 x 40 x 3 – this size is friendlier to the bulk of gate latches. Please remember to ask for a lock box if you want a standard lock or lever set.

Other latching is available and is continually being developed by D and D Technologies. Their polymer and stainless steel latches are very popular and can also be locked with a key.


Wet painting: by you, or by us.

Powder Coating:   either gal steel or aluminium frames. This coating is very popular and most warranties on the coating are for 10 years.

Hot Dip Galvanising: the gate is cleaned and dipped into molten zinc, coating the steel frame which has much improved corrosion protection. The zinc become a sacrificial element that will deteriorate slowly over many years depending on the environment – a white power will become evident on the surface.

Hot Dipped Gal and Powder Coated: even better again for corrosion resistance and you can select the colour that best suits your home.

Order and Installation process

Once we have agreed on style, colour and price, you will need to confirm your order in writing by email and place a 10 % deposit. We will then revisit your site and re-measure all dimensions before processing your order.

For larger projects, a QBCC contract will be required under the Builders Licensing laws.

Depending on your requirement, orders typically take 14 working days to manufacture from the sign-off of drawings/sketches. Extra delays can be expected in peak season – October to December – while extra time is also required for Hot Dip Galvanising. This peak season is created by extra security needs due to vacations away from home, pool building season (with many more pool fences) and the holiday period.

While your gates are being manufactured, we can be installing hinge or guide posts, concreting footings or building retaining walls (if required) to hold back the earth for the opening footings for sliders.

On completion of your gate we will collect or have delivered to your site – we usually install and complete the automation if required at the same time.

Hand over is then performed with an induction on the operation and maintenance or the equipment installed, manual release mechanism and control of pests.

After Gate Installation Care

We are also happy  to arrange a service agreement for the proper maintenance typically every 12 months for domestics installations, and 3-6 months for commercial installations (or as determined by the duty cycles).
