GRC decorative line is airtight cementitious material, so it must have the corresponding thickness, so that the intermolecular affinity to achieve the best, so as to ensure a certain service life and remain intact in the use of the period, the average thickness of good quality should be more than 8 mm. If too thin, not only short service life, poor safety performance, and in the transportation and installation process of the breakage rate is larger. Currently on the market part of the GRC decorative line products, because the manufacturers one-sided pursuit of profit, take the edge of the thick and thin in the middle of the means to deceive consumers.
There are two ways to identify GRC decorative lines like this:One is the weight of the identification, a width of 10 centimeters, the length of 2.44 meters of the standard weight of less than 2.3 kilograms, different lengths can be extrapolated according to this ratio; the second is to see whether the thickness of the sawn-off cross-section of 8 millimeters. GRC decorative lines are mostly hollow, so as to ensure that the self-weight is small, easy to install, and 15, 20mm wall thickness, plus which the nylon mesh, to ensure its overall rigidity and toughness, overall rigidity is easy to ensure that the effect of the line does not occur larger deformation, and toughness is to make it more like the strength, stiffness of the overall micro-miniaturization of reinforced concrete.
