What are the requirements for outdoor cable tray？
Outdoor cable trays, as the name suggests, are installed for outdoor use and should consider rain, wind, and corrosion protection
The rainproof bridge includes four rainproof measures: (1) Cover plate ridge: effectively avoiding the accumulation of rainwater.
(2) One end of the cover plate is welded with a cover plate: used to cover the gap between the cover plates when connecting cable trays to prevent water from falling into the gap.
(3) Cover plate welding lock: Lock the cover plate and bridge, mainly used to prevent the cover plate from being lifted by strong winds.
(4) Bottom flushing hole of bridge: In case of heavy rain, if rainwater seeps into the connecting hole, it can be discharged in a timely manner.
The anti-corrosion of rainproof bridge structures is of utmost importance,
To ensure a service life of more than 10 years for outdoor installation, the most cost-effective option is hot-dip galvanized rainproof bridge, made of high-quality cold-rolled steel plate and treated with overall hot-dip galvanizing.
Of course, if you have the same amount of money and have special requirements for the usage environment, you can choose higher quality stainless steel or aluminum alloy materials for processing.
