Why Pengelly?

We deliver steel on time, on budget and it fits first time. That’s our pledge. Sounds simple doesn’t it…. We make it happen.

How do we do it? We have our Pengelly Process combined with old fashioned hard work driven by our hands-on management team.

We sweat the small stuff…ITS ALL IN THE DETAIL. We get Architects and Engineers drawings and resolve the details. We make the steel, concrete and timber connect so it fits first time using common sense, Engineers knowledge and state of the art software. This takes time and costs money but its why our customers keep coming back to us as the time taken up front saves time later.
