The dimensions of export specific Cable Trays strictly follow international construction standards and are compatible with overseas engineering acceptance specifications in Europe, America, Southeast Asia, the Middle East, Africa, and other countries. Different from the conventional tray size system in China, the overall use of international universal modulus parameters has higher dimensional accuracy and smaller tolerance range. It can perfectly connect with various foreign-related engineering projects such as overseas mechanical and electrical installation, foreign trade infrastructure, and overseas factory assistance, avoiding problems such as installation rework and failed acceptance caused by size discrepancies.

The mainstream size specifications for foreign trade are complete and suitable for overseas conventional wiring conditions. The commonly used width of export cable trays includes international common modules such as 50mm, 100mm, 150mm, 200mm, 300mm, 400mm, etc. The height corresponds to overseas standard sizes such as 30mm, 50mm, 80mm, 100mm, etc., which are suitable for the strong and weak wire and cable laying needs of overseas civil buildings, industrial plants, and municipal engineering. The single section length adopts the mainstream foreign trade standard specifications of 3 meters and 6 meters, suitable for overseas mechanized installation and construction, and in line with international engineering modular wiring construction standards.

The thickness of the board follows international export grading standards, with strict dimensional accuracy. The thickness of the entire series of boards is strictly divided into three parameter standards: light, medium, and heavy according to overseas engineering specifications. The thickness tolerance is controlled within a very small range, and the board surface is flat and the size is regular, eliminating problems such as uneven thickness and pattern deviation. Compared to ordinary domestic cable trays, export cable trays have undergone standardized optimization in terms of length to width ratio, bending angle, and opening size, adapting to the universal installation dimensions of overseas brackets, connectors, and fixed accessories, and compatible with supporting materials from multiple countries.

The export size of the irregular shape can be customized to meet the specific engineering requirements of each country. For special construction specifications in some countries and regions, non-standard width dimensions, special heights, thickened and widened versions, customized hole spacing dimensions and other special parameters can be customized. At the same time, the dimensions of supporting accessories such as elbows, tees, reducers, and cover plates are all uniformly matched with the international parameters of the main bridge frame. The entire product set is standardized and modular in size, which can meet the core requirements of overseas batch installation, rapid construction, and unified acceptance, and is suitable for various foreign customized size orders.
