At Rollsec, we’re interested in providing industry professionals with sheet metal that is of the highest quality. But what is it that makes sheet metal what it is? What separates the good from the bad? We’re here to provide you with the necessary information to help you make an informed decision when purchasing metal for your business.

Magnaflow Self-Healing Pre-Painted Steel

Magnaflow is one of the most popular choices of sheet metal. It is a hot-dipped zinc/aluminium/magnesium alloy coated steel coil with a 240gm/m2 coating weight. It has a corrosion resistant chromate conversion coating, a flexible corrosion resistant chromated primer, and a finishing coat of flexible exterior acrylic, polyester or modified polyester coating. Its wash coat is the standard Shadow Grey colour with gloss levels of 25% measured in accordance with ASTM D523-14. That being said, Magnaflow is available in other colours that can be viewed here.

Magnaflow is sought after throughout the industry for a variety of reasons, including its scratch resistance, impact resistance, and heat resistance. When bent around a diameter equal to five times the thickness of the sheet, there is no loss of paint adhesion, making this an excellent sheet metal for a variety of businesses and requirements throughout Brisbane.

Rollsec recommends Magnaflow for roofing, cladding, and rainwater goods. In environments where corrosion levels are moderate, Magnaflow is the perfect solution. Things like animal shelters and flashings would do well with Magnaflow sheet metal’s high performance and durability. Though we would not recommend Magnaflow for water tanks and areas that are constantly wet, in contact with concrete or where lime deposits are evident, or in contact with soil. Please see our other sheet metal options if you are looking for solutions for these environments and structures.
