For volume orders, we can match custom grey shades beyond the standard RAL chart. The coating is applied on a continuous coil line \u2014 color stays consistent from the first sheet to the last.<\/p>\n
Key Features<\/h2>\n
Appearance<\/strong> Strength & Load Capacity<\/strong> Water Drainage<\/strong> R\u00e9sistance \u00e0 la corrosion<\/strong> Thermal Performance<\/strong> Installation Speed<\/strong> 14 standard RAL grey tones are in stock, from RAL 7000 (squirrel grey) through RAL 9007 (grey aluminium). We can match custom grey shades for volume orders. The color is baked onto the coil at the factory \u2014 it does not chalk or fade the way post-painted sheets do.<\/p>\n Matte finish scatters light, which hides minor surface scratches and roll-forming marks. Gloss finish reflects more light and gives a sharper appearance. Both use the same base coating chemistry. Gloss tends to show dirt more quickly. Matte is the more common choice for industrial roofing.<\/p>\n Yes, but different RAL codes run as separate coil lots. If your project uses multiple grey tones, expect each shade to ship as a separate batch. For large roofs using a single shade, one coil lot ensures color consistency across every sheet.<\/p>\n Sheets are stacked, wrapped in waterproof film, and secured on reinforced wooden pallets or steel cradles. Long sheets (8m+) ship in open-top containers or on flat racks. All packaging is ocean-freight rated with moisture barriers.<\/p>\n 10 tons. Mixed widths and lengths within the same shade can be combined to reach the MOQ.

\nGrey tones are clean, professional, and architecturally neutral. The corrugated profile creates shadow lines that add depth to the roof plane. Matte finish hides minor surface variations. Gloss finish gives a sharper, more contemporary look.<\/p>\n
\nThe corrugated rib geometry gives the sheet high bending stiffness relative to its gauge. Depending on profile and thickness, tensile strength runs from 300 MPa to 600 MPa. Purlin spacing tables available on request for specific wind and snow load requirements.<\/p>\n
\nThe corrugated wave pattern channels water to the eaves. Correct side-lap and end-lap sealing keeps the underlayment dry in heavy rain. The sheet-to-sheet connection seals against driven rain when installed to spec.<\/p>\n
\nThe base substrate is galvanized or galvalume steel. The factory coating adds a second barrier. For coastal and high-humidity environments, step up to PVDF topcoat for maximum protection.<\/p>\n
\nGrey shades reflect more solar radiation than dark colors while absorbing enough to help with snow melt in cold climates. When used as the face sheet of a metal sandwich panel, the assembly provides excellent thermal insulation for temperature-controlled buildings.<\/p>\n
\nStandardized dimensions, precise cut-to-length, and light weight mean fewer workers can lay more roof area per shift. Sheets are light enough to hand-position on the purlins. Self-tapping screws go in fast with standard power tools.<\/p>\n![\"Grey](\"https:\/\/www.bomissteel.com\/wp-content\/uploads\/2026\/05\/Grey-Corrugated-Roof-Sheets-RAL9006.webp\")
