<p>A wall facing panel has a base of sheet metal and on a front face of which there are convex elements and/or concaves producing a textured design; the convex elements are made with a diameter of 0.001 mm to 25 mm, and the concaves are made with 0.01 mm to 25 mm and a depth not exceeding 0.95d where d is the thickness of sheet material; the design is made in conformity with the condition Sconv/Sconc.=0.05−19.0 where Sconv. is the combined area of the convex of the convex elements, and Sconc is the combined are of the concaves, and the metal base is made with the thickness d=0.02-5.0 mm. The textured design has regular spacing of the convex elements and concaves on the front face of the panel, with random spacing of the convex elements and concaves, or with a mix of regular and random spacing of the convex elements and concaves on the front face of the panel.</p> |
