Accuracy of production and processing

The production and processing accuracy of stainless steel thin plates can be found in the following specifications: The following content: Direct part length error: when the length is 2.3m, 3mm; When the length is 6 meters, it is 4 mm. The total width error of straight bends: 2mm when the total width does not exceed 400. When the total width exceeds 400mm, it is 3mm. The specification errors of other prefabricated components shall comply with the requirements of Class C in the GB/T1804 standard "General Dimensional tolerance, linear dimensions do not specify dimensional tolerance". The surface of the cable tray should be smooth and flat, without burrs, sharp edges or other defects, to avoid damaging the cable sheath of the cable during operation.

Surface solutions

During the entire galvanizing process of steel parts, the thickness of the protective layer should be ≥65μm. The surface coating should be symmetrical, smooth, free of burrs, burns, scratches and other defects. Most importantly, no electroplating points should be missed. Only a fine galvanized coating can ensure the corrosion resistance of steel parts, thereby guaranteeing the service life of the bridge frame. After the adhesion inspection of the coating, there shall be no defects such as peeling, flaking or protrusion. The installation instructions for screws and seals should also be for galvanized products.

Wholesale of Galvanized cable trays

Galvanized cable tray wholesale manufacturers introduce welding quality to you:

The quality of electric welding determines the overall reliability of the bridge frame. Its welding method is closely related to the appearance of the bridge, so it has two levels. Spot welding should be symmetrical, uniform, round and without obvious defects.

Bridge load stiffness requirements:

The relative stiffness of a bridge directly under rated load should not exceed 1/200. The ratio of the length of the support arm to the maximum deflection of the support frame should not exceed 1/150.
