Sunshine coast security screens and doors corrosion is probably the biggest issue when it comes to product selection. Often on the sunshine coast i’m replacing a lot of RUSTED OUT items. A very common product using 304 GRADE MESH This isn’t 316 MARINE GRADE and should not be used on the sunshine coast so choose wisely. Prowler Proof is the only welded security system in Australia where no metal comes in contact with each other, such as screws holding the mesh together or pop rivets or screws in the corners of doors. This is where all the corrosion issues start, especially when screws are used to hold in the stainless mesh. Being on the sunshine coast this is the number 1 issue when it comes to choosing a quality product. this is why East Coast Security Screens proudly partners with prowler proof welded security systems
