Fireproof spray plastic steel cable tray is a treatment method of spraying fireproof coating on the surface of steel cable tray. Compared with ordinary steel cable trays, fire-resistant spray plastic steel cable trays have the following characteristics:

防火性能好：防火喷塑钢制桥架表面的防火涂料可以起到一定的防火作用，能够有效地减缓火势，降低火灾危险。

Good fire resistance: The fireproof coating on the surface of the fire-resistant spray molded steel bridge can play a certain role in fire prevention, effectively slowing down the fire and reducing the risk of fire.

耐腐蚀性能好：防火喷塑钢制桥架经过防火涂料的处理，在防火的同时还能够起到防腐蚀的作用，延长使用寿命。

Good corrosion resistance: The fire-resistant spray plastic steel bridge is treated with fire-resistant coating, which can not only prevent fire but also play an anti-corrosion role, extending its service life.

美观耐用：防火喷塑钢制桥架的表面处理工艺可以使其具有较好的外观质量，同时也能够增强其耐用性。

Beautiful and Durable: The surface treatment process of the fireproof spray plastic steel bridge can provide it with good appearance quality and also enhance its durability.

安装方便：防火喷塑钢制桥架的安装方式与普通钢制电缆桥架相同，安装简单方便，节省时间和成本。

Easy installation: The installation method of fire-resistant spray plastic steel cable tray is the same as that of ordinary steel cable tray, which is simple and convenient to install, saving time and cost.

需要注意的是，防火喷塑钢制桥架虽然具有一定的防火性能，但并不能完全防止火灾发生，因此在使用过程中，还应该采取其他防火措施，如使用防火隔板、定期检查电缆桥架等。

It should be noted that although fire-resistant spray molded steel cable trays have certain fire resistance performance, they cannot completely prevent the occurrence of fires. Therefore, during use, other fire prevention measures should also be taken, such as using fire barriers and regularly inspecting cable trays.

防火喷塑钢制桥架和室内喷塑桥架的区别主要在于以下几个方面：

The difference between fire-resistant spray plastic steel cable trays and indoor spray plastic cable trays mainly lies in the following aspects:

防火性能不同：防火喷塑钢制桥架表面的防火涂料可以起到一定的防火作用，而室内喷塑桥架并不具备防火性能。

Different fire performance: The fire retardant coating on the surface of the fire-resistant spray molded steel bridge can play a certain role in fire prevention, while the indoor spray molded bridge does not have fire resistance performance.

适用场所不同：防火喷塑钢制桥架多用于高层建筑、地铁、大型公共场所等需要严格防火的场所，而室内喷塑桥架一般用于普通的室内环境。

Applicable places are different: fireproof plastic sprayed steel bridge is mostly used in high-rise buildings, subways, large public places and other places that need strict fire protection, while indoor plastic sprayed bridge is generally used in ordinary indoor environment.

材质不同：防火喷塑钢制桥架是以钢为基材，在钢桥架表面喷涂防火涂料，而室内喷塑桥架多采用塑料、铝合金等材质。

Different materials: Fireproof spray molded steel bridge trays are made of steel as the base material and sprayed with fireproof paint on the surface of the steel bridge frame, while indoor spray molded bridge trays mostly use materials such as plastic and aluminum alloy.

价格不同：防火喷塑钢制桥架具有防火性能，材料成本较高，因此价格相对较高，而室内喷塑桥架的材料成本较低，价格也相对较低。

Price difference: Fireproof spray molded steel cable trays have fire resistance and high material costs, resulting in relatively high prices. However, indoor spray molded cable trays have lower material costs and prices.

综上所述，防火喷塑钢制桥架和室内喷塑桥架在防火性能、适用场所、材质和价格等方面存在较大差异。选择哪种电缆桥架需要根据实际使用场景和需求来进行选择。

In summary, there are significant differences in fire performance, applicable locations, materials, and prices between fire-resistant spray molded steel cable trays and indoor spray molded cable trays. The selection of which type of cable tray needs to be based on actual usage scenarios and needs.
