    Real COLA projects, real results

    With over 20 years of shade solution experience, Greenline has provided multiple schools with a COLA customised to their learning environments and students’ needs. All of our shade structures are made to withstand harsh weather conditions while also being aesthetically pleasing.

      • 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.

      • 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.

      BEAUTIFUL DESIGNS THAT AREN’T PRACTICAL

      Designs that look great on paper but aren’t feasible can inflate costs and delay projects. Greenline delivers practical solutions, ensuring your vision becomes a reality on time and on budget.
