1、优质的防滑板所用的济南铝板，厚度、强度和氧化膜等，应符合国家的有关标准规定，壁厚应在1.2毫米以上，抗拉强度达到每平方米毫米157牛顿，屈服强度要达到每平方毫米108牛顿，氧化膜厚度应达到10微米。如果达不到以上标准，不可使用。
Jinan aluminum, thickness, strength and quality oxide film cleat used shall comply with the provisions of the relevant national standards, should be 1.2 mm wall thickness, tensile strength reached 157 Newtons per square millimeter, the

yield strength to reach every square Newton 108 mm, the thickness of the oxide film should reach 10 microns. If you can not reach the above criteria, can not be used.

2、优质的济南铝板防滑系列的，加工精细，安装讲究，密封性能好，开关自如。劣质的铝合金门窗，盲目选用铝型材系列和规格，加工粗制滥造，以锯切割代替铣加工，不按要求进行安装，密封性能差，开关不自如，不仅漏风漏雨和出现玻璃炸裂现象，而且遇到强风和外力，容易将推拉部分或玻璃刮落或碰落，毁物伤人。
Jinan quality aluminum skid series, precision machining, installation stress, good sealing performance, switch freely. Poor quality of aluminum windows and doors, aluminum blind selection series and specifications, processing shoddy, to sawing and milling instead, do not follow the requirements for installation, sealing performance is poor, the switch does not freely, not only leakage leaks and burst phenomenon occurs glass, and in case to strong winds and external,easy to push and pull part or glass scraped off or touch down, wounding and breaking things.

3、在一般情况下，优质济南铝板防滑系列的因生产成本高，价格比劣质的要高30%左右。为了降低成本偷工减料，以次充好，产品的隐患较大，一般不宜采用。
In general, due to the high cost of production of high quality aluminum skid series Jinan, the price to be higher than the inferior about 30%. In order to reduce the cost of cutting corners, shoddy, greater product risks, generally should not be used.
