一场完美的舞台演出离不开音响灯光设备的支持，也离不开铝合金桁架的支持。其实对于表演舞台搭建工作而言，铝合金桁架已经成为不可或缺的一部分，它的质量好坏直接影响舞台的搭建效果。所以高质量的桁架的使用是举办一场成功演出的前提，质量有了保证就更能有效保障人身安全和避免财产遭受损失。这么一看，铝合金桁架的正确选型至关重要，购买者有必要对以下的内容多加留意。
桁架表面的光泽度
口碑好的的铝合金桁架的表面一般都会出现明显的光泽，这是因为经过蘸酸的处理的桁架能够保持外观的光彩夺目和美观大方。所以消费者在选购产品的过程中可以通过观察表面光泽，来选择真正合格的产品
安全性能
购买产品一定要选择最放心的铝合金桁架品牌，从而可以保证使用的安全性。优质的铝合金桁架通过改善以往的钢架结构，以在两端焊接堵头的方式大大提高了受力强度，有效避免出现变形和垮塌的问题。
The surface of aluminium alloy truss with good reputation usually shows obvious gloss, because the truss dipped with acid can keep its appearance bright and beautiful. So in the process of choosing and purchasing products, consumers can choose truly qualified products by observing the surface gloss.
Safety performance
Purchase of products must choose the most assured brand of aluminum alloy truss, so as to ensure the safety of use. High-quality aluminium alloy truss greatly improves the mechanical strength by improving the previous steel structure, and effectively avoids the problems of deformation and collapse by welding plugs at both ends.
