With professional and productive factory, Changzhou Qiaobang Storage Equipment Co.,Ltd is one of the top level China 100×300 straight wire cable tray manufacturers, welcome to wholesale products from us.Model:100 * 300Materials:Q235B steel / 304/316 stainless steel / 316L stainless steelSurface:Galvanized - zinc coating thickness 10um or more, suitable for indoor use.Hot-dip galvanizing - zinc coating thickness 60um or more, suitable for outdoor use.Electropolishing - for stainless steel surface treatment.Spray plastic - for applications that require color of the occasion.Dimensions:All the below size on inner diameter.Depth: 35mm, 50mm, 60mm, 75mm, 100mm & 150mm or customer specified.Width: 50-900mm.Length: 1 m 3 m ---Material diameter: 3.8 ~ 6.0mm.Open Grid bridgeOpen grid-type bridge so that all cables are visible stud, you can fully control the quality of the wiring project, in case of failure in the future, they can quickly identify problems and take appropriate measures to cable because cable and natural ventilation, heat It will not come, you can use a smaller cross-sectional area of the cable, thereby reducing the cable purchase costThe open grid-type bridge allows qualify from any point, you can easily connect and various machinery and equipment, is able to change the qualifying points; and it is light and flexible, it can be installed on top of production equipment, and under the surrounding, you can easy walk to various intermediate devices along the production line, assembly line installation.Durable, safe and secure. Grid-type bridge is made of high quality steel welded together, it is the world's largest bridge to pass the test in order to provide the strongest and lightest weight bearing capacity for users. In addition to electro-galvanized and hot dip galvanized surface treatment, mesh trays and accessories are also provided by the decontamination process high quality 304L and 316L stainless steel, after the salt spray test surface, its life is untreated stainless steel three to four times, even in the harsh environment can ensure long-term durability.The fire performance and strong - at 1000 degrees Celsius temperature can be maintained for 90 minutes, to protect the safety of the bridgeThe mesh trays can be used for a variety of installation, and does not require special customized components such as bends, tees, crosses, reducers, and so on. These special components are available in a straight segment bridge construction site using simple tools (pliers) made directly to help users shorten the design and installation time. In addition, this new structure also can better control cables, future maintenance and upgrade time is also very simple, than the traditional tray save at least 1/3 of installation time.Grid-type bridge and some places its own unique innovations, such as its quick-mount system, direct snap bracket and bridge; patented quick connector, two bridge can not screw nut and fast connection, which can help reduce installation time for the timely completion of the project.
