The 275g zinc aluminum magnesium porous Cable Tray, relying on a standardized specification system, is suitable for most domestic and foreign power, new energy, and municipal wiring projects. The regular parameter design greatly improves the universality and adaptability of the product, making it an extremely versatile cable tray category in engineering wiring. Its specification system mainly covers three core dimensions: size parameters, sheet parameters, and punching parameters. All standard specifications conform to the industry's general construction specifications and can meet the needs of conventional laying and lightweight construction.

In terms of external dimensions and specifications, this bridge has a complete standardized series of length, width, and height. The industry standard width covers the range of 100mm to 600mm, and the height is compatible with two mainstream styles of 50mm and 100mm. The length is mainly determined by standard sizes of 2 meters, 3 meters, and 6 meters. Among them, the 6-meter length specification is more suitable for large-area and long-distance pipeline laying, which can reduce splicing nodes and improve wiring regularity. For special construction scenarios such as narrow pipe galleries and equipment interlayers, non-standard size adjustments can also be supported to flexibly adapt to various installation spaces.

The thickness of the board is a core specification parameter that directly affects the load-bearing performance of the bridge. The conventional national standard thickness includes multiple levels such as 0.8mm, 1.0mm, 1.2mm, 1.5mm, etc. Thin sheets are suitable for indoor weak current and small cable laying, while thick sheets can meet outdoor large-span and multi cable heavy-duty laying scenarios. Uniformly matched with 275g/㎡ zinc aluminum magnesium alloy coating, the coating thickness is uniform and stable, ensuring the basic anti-corrosion ability of products with different thickness specifications, and the specification adaptability runs through various projects with light and heavy loads.

The porous structure has a fixed standardized punching specification, which is also the core characteristic parameter of this product. On both sides and at the bottom of the bridge, evenly arranged installation holes and heat dissipation holes are reserved. The aperture and spacing of the holes are in accordance with industry standards, and the hole positions are symmetrically and orderly arranged without damaging the overall structural strength of the board. The standardized punching specifications enable standardized operations for bracket fixation, cable binding, and grounding installation, without the need for on-site secondary processing, while ensuring uniform ventilation, heat dissipation, drainage, and moisture resistance of the bridge.

In addition, the specifications of supporting accessories are precisely matched with the main bridge frame, and accessories such as bends, tees, reducers, brackets, and partitions are customized according to the size of the main frame, with a unified specification system and strong installation compatibility. During procurement and construction, matching corresponding specifications based on laying load, installation environment, and cable quantity can effectively improve the standardization and stability of wiring engineering.
