1、室内环境

1. Indoor environment

①. 一般可选择钢质或铝质普通型桥架,槽式或托盘式结构均可。

①.  Generally, steel or aluminum ordinary cable trays can be selected, and groove or tray structures are both acceptable.

②. 如需美观,可以选择装饰型钢桥架。

②.  For aesthetics, decorative steel bridge frames can be chosen.

③. 公共场所大跨距(>3米)情况下,应选用承重能力较强的复合型桥架。

③.  In public places with large spans (>3 meters), composite cable trays with strong load-bearing capacity should be selected.

2、腐蚀环境

2. Corrosive environment

①. 应优先选择玻璃钢、环氧树脂或热浸镀锌处理的钢质桥架。避免使用普通钢质。

①.  Steel cable trays treated with fiberglass, epoxy resin, or hot-dip galvanizing should be given priority. Avoid using ordinary steel.

②. 桥架附件也应采用相应防腐材料。

②.  The accessories of the bridge should also use corresponding anti-corrosion materials.

③. 户外腐蚀环境严重的,必须选用复合型环氧树脂桥架或经热浸锌处理的钢质型材。

③.  For outdoor environments with severe corrosion, composite epoxy resin cable trays or hot-dip galvanized steel profiles must be selected.

④. 热浸镀锌处理可以提高钢质桥架的抗腐蚀能力,适用于中等腐蚀环境。但在强腐蚀条件下,仍应优先使用玻璃钢或环氧树脂材质。

④.  Hot dip galvanizing treatment can improve the corrosion resistance of steel cable trays and is suitable for moderate corrosive environments. However, under strong corrosive conditions, fiberglass or epoxy resin materials should still be prioritized for use.

⑤. 腐蚀环境下不建议使用普通冷轧钢板或烤漆处理的桥架。

⑤.  It is not recommended to use ordinary cold-rolled steel plates or painted bridge frames in corrosive environments.

3、火灾高危环境

3. High risk fire environment

①. 应选用阻燃型桥架,如环氧树脂或玻璃钢材质。

①.  Flame retardant cable trays, such as epoxy resin or fiberglass material, should be selected.

②. 避免使用普通钢质或铝质桥架。

②.  Avoid using ordinary steel or aluminum cable trays.

③. 大跨距情况下,阻燃等级高的复合型桥架。

③.  In the case of large spans, composite cable trays with high flame retardant ratings are preferred.

4、室外环境

4. Outdoor environment

①. 宜密封盖板的复合型桥架,如玻璃钢、钢管套型等。这可以提供轻量化及优异的抗腐蚀性能。

①.  It is advisable to choose composite cable trays with sealed cover plates, such as fiberglass and steel pipe sleeve types. This can provide lightweight and excellent corrosion resistance.

②. 也可以选择经过热浸锌处理的钢质开口型或封闭型桥架。热浸锌可提高桥架抗腐蚀性。但长期暴露在外仍需注意维护。

②.  You can also choose steel open or closed bridge frames that have been hot-dip galvanized. Hot dip galvanizing can improve the corrosion resistance of cable trays. However, long-term exposure still requires attention to maintenance.

③. 如果采用热浸锌钢质桥架,可加装盖板改善防尘防雨效果。

③.  If hot-dip galvanized steel cable trays are used, cover plates can be installed to improve dust and rain resistance.

④. 大跨距情况下,优先选用复合型桥架或钢质行架。

④.  In the case of large spans, composite cable trays or steel frames are preferred.
