Bridge is a long-term use of materials, in many complex environments have applications, at this time the quality requirements of cable bridge is very important, the following cable bridge manufacturers will give you a summary of the main points of the bridge's appearance inspection, I hope to help you!

桥架产品包装箱内应有装箱清单、产品合格证及出厂检验报告。托盘、梯架板材厚度应满足规定。表面防腐层材料应符合现行有关标准的规定。

There should be packing list, product certificate and factory inspection report in the box of bridge products. The thickness of pallets and ladders should meet the requirements. Surface anticorrosive coatings should comply with the relevant national standards.

热浸镀锌的托盘、桥架镀层表面应均匀，无毛刺、过烧、挂灰、伤痕、局部未镀锌（直径2mm以上）等缺陷，不得有影响安装的锌瘤。螺纹的镀层应光滑，螺栓连接件应能拧入。

Hot-dip galvanized pallet and bridge plating should be uniform, without burrs, burning, hanging ash, scars, local non-galvanized (diameter more than 2 mm) defects, and no galvanoma affecting installation. The plating of the threads should be smooth and the bolted joints should be able to be screwed in.

电镀锌的锌层表面应光滑均匀，致密。不得有起皮、气泡、花斑、局部未镀、划伤等缺陷。

The surface of galvanized zinc coating should be smooth, uniform and compact. No flaws such as peeling, bubbles, spots, partial non-plating, scratches, etc. shall be allowed.

Spraying should be flat, smooth, uniform, no skin, no bubbles and blisters.

桥架焊缝表面均匀，不得有漏焊、裂纹、夹渣、烧穿、弧坑等缺陷。

The weld surface of the bridge frame is uniform, and there shall be no defects such as welding leakage, cracks, slag inclusion, burning through, arc pits, etc.

桥架螺栓孔径，在螺杆直径不大于M16时，可比螺杆直径大2mm。

The diameter of bolt hole in bridge frame is 2 mm larger than that of bolt when the diameter of bolt is less than M16.

螺栓连接孔的孔距允许偏差:同一组内相邻两孔间距±0.7mm,同一组内任意两孔间距±1mm;相邻两组的端孔间距±1.2mm。

The allowable deviation of the hole spacing of bolt connection holes: the spacing of adjacent two holes in the same group (+0.7 mm), the spacing of any two holes in the same group (+1 mm), and the spacing of end holes in adjacent two groups (+1.2 mm).
