Do Shade Sails Need Engineering?

One questions that often comes up with clients is, are shade sails engineered? The quick answer is yes. Shade sails definitely should be engineered – and correctly engineered structures will last you much longer than poorly designed and engineered ones.

Why do they need engineering?

Structural engineering is effectively the process of designing the ‘bones and muscles’ of a structure. This allows the finished structure to withstand outside elements like wind and heavy rain, as well as day to day use of the structure. Sails are under high tension and if they were to come loose they can be dangerous, if not lethal. This isn’t a risk you can afford to take, especially if your shade sail is in a public space or part of an organisation like a school or childcare centre.

What do engineers’ factor in?

Engineers look at wind speeds, the terrain of the area, the size and height of your structure, other buildings in the area, the type of fabric being used (shade or all-weather/PVC), and more. All these factors play a part in determining the size of steel needed, the type of connections required, and the depth of the foundations.

Generic Engineering

Generic engineering is where an engineer looks at a region as a whole and uses the typical/normal measurements for factors like wind, terrain in that area and recommends the engineering specifications for structures. These engineering recommendations are then used for any structures which are built in this region.

– Allows engineering to be done in ‘bulk’ which saves money.
– No need to liaise with an engineer for every project, which makes the project timeline shorter.

– if the generic parameters used don’t exactly match your site, the engineering recommendations may be unsuitable
– although the structure may be sound, it may not be as efficiently engineered as it could be.

Site Specific Engineering

Site specific engineering is where each project is engineered based on the exact factors in the location of the structure. This means factors like surrounding buildings, and specific
terrain differences can be factored into the calculations, as well as more precise winds speeds and wind directions.

– peace of mind that the structure is engineered specifically for your site’s conditions
– produces the most efficient structure for your site

– as engineers are used for every project, this adds to the cost of the project, and will extend the timeline slightly.

To wrap this up, neither generic or site-specific engineering is always the ‘right’ or ‘wrong’ way to go – but your shade structure absolutely does need to be engineered!

Make sure your contractor is using an engineer that is registered with the NER and you receive a copy of the engineering drawings and certificate.

Barnawartha Primary School - Bernadette Kelly

Extremely easy to deal with. Professional service. Very happy with the completed job.

Echuca East Primary School, Jodi Boal

I find engaging with Greenline completely professional. The customer service is exemplary and the three projects I have been involved in with Greenline gives me confidence in their communication, ability to meet deadlines and appease a customer, quality of work, competency in meeting regulations and OHS measures

I have great confidence in this team/company.

Wodonga Primary School - Damian Duncan - Principal

I have used Greenline for a number of years now as I have always found them to provide excellent customer service, great quality and reliability. Our most recent project was a covered walkway to provide extra shelter for our students.

From day one, the walkway was such a big hit, with so many students using it that we actually had to provide extra staff in the area for additional student supervision. Thank you Greenline.

Wyndham Central College - Bryan Wollard - Assistant Principal

From my first meeting with a Greenline representative I was very impressed with the professional presentation about the company.

The process relating to construction was very well explained with timelines, contractors details and

Overall, the finished product is absolutely great. It has exceeded all our expectations and is now a real asset for the school.

Greenline did a great job here and I would recommend them to any school wanting to develop a COLA.

Ardeer Primary School - Graham Miller - Principal

Greenline were a pleasure to deal with. Their communication was excellent and we are thrilled with the end product.

Mount Waverley Heights Primary School - Sharon Reiss-Stone - Principal

A huge thank you and congratulations to the team at Greenline for delivering BIG TIME our outdoor shade shelter. The shelter, which covers one of our outdoor basketball courts, gives our students a chance to play through all weather conditions and looks great. Their post project support has been fantastic with quick follow-ups and service to the school.

Croydon Hills Primary School - Christian Holdsworth - Principal

We found Greenline to be professional throughout our entire business relationship, from our initial communications through to the completion of our project. Their friendly, helpful advice was offered with constant consideration of our needs. Greenline were able to meet all deadlines with competency, completing our project with the highest quality of work.

Bundoora Primary School - Lee Pollard - Principal

Greenline were a professional and well organised company to work with. The finished product was of a high standard and met the school’s requirements.
