Coloursteel is pre-coated steel which is then formed into the panel shape in a limited colour range. They are all light grey on the inside.
Powdercoated Steel doors are formed first, then electrostatically applied powder is the baked and fused onto the steel surface. There is a very large colour range and the colour is the same on both sides of the door panel.
Lubricate all moving parts – hinges, wheels, springs with WD40 or TAC2 every 6 months. Wash down door panels with warm, soapy water and soft brush 3 – 4 times per year.
