There are a wide variety of ladder type Cable Trays on the market, which can be finely classified according to engineering environment, load-bearing requirements, and anti-corrosion requirements. Unlike the single enclosed structure of trough type cable trays, the classification of ladder types is more in line with the special needs of power wiring, covering a full range of styles such as light, medium, heavy, and special anti-corrosion, and can meet the differentiated selection standards of various industrial, power, and new energy projects.

According to the load-bearing structure, it is the most commonly used classification method in engineering, mainly divided into three categories: light, medium, and heavy. Lightweight ladder style bridge with even spacing between ladder stops and lightweight overall weight, suitable for laying conventional weak current and small power cables indoors, and mostly used for ordinary distribution lines in office buildings and factories; The main beam of the medium-sized ladder frame has been thickened and the structural strength has been upgraded, making it suitable for most industrial workshops and machine room main lines. It is currently the most versatile category in engineering; The heavy-duty ladder frame is equipped with an overall reinforced structure, which greatly improves its load-bearing performance and is specifically used for large-span high-altitude laying and high-density heavy-duty power cable wiring.

According to the classification of surface anti-corrosion processes, it can be divided into four mainstream types: electrostatic spraying, galvanizing, hot-dip galvanizing, and stainless steel. The spray painted ladder frame has a clean appearance and good oxidation resistance, suitable for indoor dry tooling scenes; Electroplated galvanized ladder frame is economical and practical, with stable basic rust prevention ability, suitable for conventional short-term and medium-term engineering projects; The hot-dip galvanized ladder frame has undergone deep galvanizing treatment and has strong resistance to weathering and salt spray, making it suitable for harsh environments such as outdoor, seaside, and tunnel; Stainless steel ladder frame is acid and alkali resistant, corrosion-resistant, and specially designed for high-risk corrosion conditions such as chemical and metallurgical industries.

In addition, there are also special customized ladder types, including large-span extended ladder, aluminum alloy lightweight ladder, flame retardant special process ladder, etc., which are specially customized for special construction sites, load conditions, and environmental requirements. The categories are fully covered, and various engineering wiring selection problems are comprehensively solved.
