Guangzhou trunking manufacturersIt is said that galvanized trunking can not only play a good role in our home decoration, but also can be used well in other industrial decoration, so galvanized trunking is an indispensable material in our daily life. How can we easily choose the right galvanized trunking? Come and have a look with Bian Xiao.
Guangzhou trunking manufacturer said that hot-dip galvanized cable tray is assembled from hot-extruded glass fiber reinforced plastic pipes and is suitable for wires and cables, frequency conversion cables, lighting lamps and accessories, etc. Compared with the iron cable tray, it has the advantages of long service life, convenient installation, low cost, convenient laser cutting, maintenance free and so on. It is widely used in the laying of hot galvanized cable tray.

2. Long-span bridges shall be verified. For steel bridges with a span of more than 6m and aluminum alloy bridges with a span of more than 2m or a load-bearing requirement greater than load level D, strength, rigidity and stability calculations or tests shall be carried out according to engineering conditions.
