为了减轻重量还可以采用铝合金电缆和玻璃钢桥架,其外形尺寸， 荷载特性均与钢质桥架基本相近,由于铝、钢比重不同(A1=2.7,Fe=7.86， 按重量计算,铝钢之比约为1：3,根据两种材质的市场价折算

　　In order to lighten the weight, aluminum alloy cable and FRP Bridge can be used. The shape size and load characteristics are almost similar to the steel bridge. Because of the different proportion of aluminum and steel (A1=2.7, Fe=7.86, according to weight, the ratio of aluminum and steel is about 1:3, according to the market price of two materials. "

　　铝合金桥架的造价费用较之同类镀锌钢桥价要高出2.0倍,玻璃钢电缆桥架具有美观,重量轻、安装方便等优点, 近年来, 铝合金桥架已在有的工程中加以应用。

　　The cost of the aluminum alloy bridge is 2 times higher than that of the same kind of galvanized steel bridge. The fiberglass cable bridge has the advantages of beautiful, light weight and convenient installation. In recent years, the aluminum alloy bridge has been applied in some projects.

　　玻璃钢电缆桥架选型时应注意桥架的所有零部件是否符合系列化、通用化、标准化的成套要求。

　　When selecting FRP cable tray, attention should be paid to whether all parts of the bridge meet the requirements of serialization, generalization and standardization.

　　建筑物内玻璃钢电缆桥架可以独立假设, 也可以附设在各种建(构)筑物和管廊支架上,应体现结构简单,造型美观、配置灵活和维修方便等特点

　　The FRP cable bridge in the building can be assumed independently and can be attached to a variety of construction (structure) and tube porches. It should be characterized by simple structure, beautiful shape, flexible configuration and convenient maintenance.

　　全部零件均需进行镀锌处理,安装在建筑物外露天的桥架,如果是在邻近海边或属于腐蚀区,则材质必须具有防腐、耐潮气、附着力好, 耐冲击强度高的物性特点。

　　All the parts need to be galvanized, the bridge installed outside the building, if it is in the vicinity of the seaside or in the corrosion area, the material must have the characteristics of anticorrosion, moisture resistance, good adhesion and high impact strength.
