Multi Functional Cable Tray

1.About Our Product
Our cable tray series has six series, including XQJ steel cable tray, MQJ steel riveted cable tray, lqj aluminum alloy cable tray, nhqj (NBC) fire-resistant non combustible tank box (fire-proof cable tray), BHQ glass fiber reinforced plastic corrosion-resistant flame-retardant cable tray, and polymer alloy plastic cable tray. It is widely used in chemical industry, light industry, metallurgy, electric power, tunnels, machinery and modern office places. The laying of all kinds of wires and cables has reached the level of standardization, serialization and generalization. It provides a wide wiring space for engineering design, construction and installation, and production automation.
Material Selection
The bridge plates of our company are high-quality ST12 or Q235 cold-rolled plates produced by Baosteel or WISCO, and plates of different thickness are selected according to the size of the order specification (the thickness of plates is selected according to cecs31:91 standard). Steel products must be submitted to the company's Testing Center for inspection with the quality assurance certificate, inspection application form and samples before planned procurement, and the warehousing procedures can be handled only after they pass the strict inspection.
Surface Treatment
Bridge surface treatment: hot galvanizing, plastic spraying.
Specifications
The steel bridge can be divided into four specifications according to the use environment:
A flat trough bridge B tray bridge C ladder bridge D combined bridge
Processing Technology
There are many processing technologies for orfeng steel bridge, which are selected by users according to the use environment:
Sheet metal Processing
A. Drawn bridge (one-time forming) B. ladder side welded bridge (large span)
Welding Technology 
A. Ordinary manual arc welding B, CO2 gas shielded submerged arc welding (with the advantages of strong rust resistance and low oxygen content in the weld)
Craft Production
Aofeng steel bridge elbow can be made by general chamfer elbow process or arc elbow process. (this process adopts Metz bending, plasma cutting, submerged arc welding and other fine processing procedures, with beautiful appearance, good overall strength, no bumps, and can fundamentally solve the problems of scratches during cable laying and large cable bending radius.)
Testing
Our steel bridge has strict inspection process from material selection, sheet metal processing, welding to surface treatment.
