Colour-coated tiles typically refer to colour-coated steel tiles or colour-coated aluminium tiles, which are profiled sheets formed by cold-rolling and bending colour-coated steel or aluminium sheets into various wave patterns. The following provides a detailed introduction:

Colour-coated steel tiles: Also known as colour-coated profiled tiles, these are manufactured from colour-coated steel sheets through roll-forming and cold-bending. They offer characteristics such as light weight, high strength, rich colour options, convenient and rapid installation, seismic resistance, fireproofing, and waterproofing. They are suitable for roofing, wall cladding, and interior/exterior wall decoration in industrial and civil buildings, warehouses, specialised structures, and large-span steel structures. Common profiles include 460, 470, and 750 types.

Coloured aluminium roofing sheets: Also termed colour-coated aluminium roofing panels or coloured aluminium alloy profiled sheets, these utilise aluminium sheets as the substrate, cold-rolled into various waveforms. Lightweight at approximately one-third the density of steel, they exhibit exceptional corrosion resistance. Aluminium forms a dense oxide film in air, and combined with fluorocarbon or polyester surface coatings, it exhibits outstanding resistance to ultraviolet radiation and oxidation. Colour retention can last 20-30 years, offering a long service life and high recyclability. Additionally, it possesses fire-retardant properties and resistance to wind and seismic forces. These tiles are widely used for roofing and wall cladding in residential buildings, villas, factories, and other structures.
