CARBOLITE Patio Covers come in a variety of shapes and sizes. You can choose between the following:
- Bullnosed Patio Covers
- Flat Patio Covers
Bullnosed Patio Covers are the traditional look suiting older style houses. The polycarbonate sheet is heat formed in our factory where the end of each sheet is heated and curved to the radius. Normally, 8mm twin wall sheets cannot be bent that tight but the heat in the oven allows the sheets to soften and sag and then the sheet is curved around a steel barrel to form the curve.The sheet is then cooled. The bullnose uses 380mm of sheet. Gutters can be attached to the front.
Flat Patio Covers becoming more and more popular as they represent the modern straight lines in today’s modern architecture. These are often placed on a 4-5 degree fall to allow water to run off and gutters can be attached for water diversion.
Both patio covers use aluminium box sections as the support structures. These member sizes vary depending on how far out the patio cover (ie the further the projection, the larger the beams). Please refer to our Engineering Page to view the patio cover frames. They show you exactly how the systems go together.
The joining bars for the sheets are also curved for Bullnosed or Flat Patio Covers. The aluminium used is a curving quality temper meaning it can be cured without stress. Our rolling machines allow a complete curve if necessary.
All frames for our systems are engineered designs that are approved to meet the most stringent standards. They comply with Australian Wind Load Standards.
