1. The length of the sheet should not exceed 8 meters. It can be cut and spliced. Over-length of the sheet will cause cracking.
2.板材正面朝阳，因板材正面掩盖有抗老化层，然后达到板材正常使用寿命；
2. The front of the sheet is sunny, because the front of the sheet is covered with an anti-aging layer, and then the normal service life of the sheet is achieved.
3.弯弧管间距以1050毫米为宜，间距过大影响板材抗风雪能力，或间接引起板材开裂；
3. The spacing of curved arc pipes should be 1050 mm. Excessive spacing will affect the snow resistance or indirectly cause plate cracking.
4.实心耐力板有必要预留伸缩孔，伸缩孔直径大于钻尾直径3毫米以上；
4. It is necessary to reserve expansion holes for solid endurance plate. The diameter of expansion holes is more than 3 mm of the diameter of drill tail.
5.架体有必要保持平整，结实，避免因架体原因造成板材破损；
5. It is necessary to keep the frame flat and firm so as to avoid plate damage caused by the frame.
6.钢结构架体资料有必要与结构面积相符合；
6. It is necessary that the data of steel structure frame conform to the area of structure.
7.装置过程中避免与酸性、碱性、油性物质、水泥等物质接触；
7. Avoid contact with acidic, alkaline, oily, cement and other substances in the process of installation.
8.铝压条规格与板材厚度和结构面积相符合；
8. The specifications of aluminium strip are in conformity with the thickness and structural area of sheet metal.
9.钻尾丝密度小于或等于30厘米，钻尾丝松紧程度应适当，不该过紧或过松；
9. The density of drilling tail wire is less than or equal to 30 cm. The degree of tightness of drilling tail wire should be appropriate, and should not be too tight or too loose.
10.装置使用中性玻璃胶完整密封缝隙，以避免漏水现象；
10. The device uses neutral glass glue to seal the whole gap to avoid water leakage.
11.在板材出售后，在运输中应轻装轻放，妥善保管，在存放期间避免阳光直接暴晒；
11. After the plate is sold, it should be lightly packed and handled in transportation, properly kept, and avoid direct sunshine during storage.
12.保护膜在施工完工后方可撕去，避免人为刮伤现象，任何情况下不可在板面上行走；
12. The protective film can be torn off after the completion of construction to avoid the phenomenon of artificial scratches and can not walk on the board under any circumstances.
13.板材曲折度根据板材厚度相应增加或减少；
13. The bending degree of the sheet increases or decreases according to the thickness of the sheet.
14.结构架体可根据跨度巨细选择型材，一般情况下，3米以下的跨度选用20*40或25*50矩形管，8米以下跨度选用40*80或多或50*100矩形管，8米以下跨度主张做双梁结构，或找正规资质单位做结构设计;
14. Structural frame can choose profiles according to the span size. Generally, 20*40 or 25*50 rectangular pipes are selected for spans less than 3 meters, 40*80 or more or 50*100 rectangular pipes for spans less than 8 meters, and double-beam structures are advocated for spans less than 8 meters, or formal qualified units are selected for structural design.
15.装置需要冷弯时，曲折方向不可垂直于板材筋肋的方向，冷弯的半径有必要大于板厚175倍。
15. When the device needs cold bending, the bending direction should not be perpendicular to the direction of plate ribs. The radius of cold bending must be 175 times larger than the thickness of plate.
