&Nbsp;   1, the Board prohibit contacts of alkaline substances and corrosive solvents, such as alkali, alkaline salts, amines, ketones, aldehydes, esters, ethers, sodium water, methanol and isopropyl alcohol. Paint a skeleton face must not touch the plate.
&Nbsp;   2, must use suitable for Polycarbonate plastic of neutral-density rubber and rubber pads.
&Nbsp;   3, drilled to allow expansion of steel sheet when installing migration, hole diameter should be greater than diameter of screw 50%, and the screw holes of the plate edge distance of not less than 50mm, cannot get the screws too tight. Screws should not be too dense, it is recommended that every 50cm or above using a screw (plate thickness screw spacing required bigger and bigger).
&Nbsp;   4, two plates of joints depending on changes in local temperature allow sufficient expansion space. Under normal circumstances the slit width for the screw diameter more than 50%.
&Nbsp;   5, when bending, bending shall be perpendicular to the direction of plate edges reinforced, Leng Wan 175 times the radius of Sun sheet must be greater than the plate thickness times the endurance plate cold bending radius must be greater than the plate thickness of 100 times. Leng Wan RADIUS formula: R=1/2h+ square/8h (r = bend RADIUS; h= arch, high m=-span).
&Nbsp;   6, direct drilling and screw on the Board in the construction process should lay the screw holes, and then screw on. If sheet need bent shape, bending stress points on the non-screw.
&Nbsp;   7, regular cleaning and maintenance to prevent corrosion of acid and alkali dust sheets, recommended washing with warm water.
