Cable tray bends are manufactured from hot-dip galvanized steel sheet with a thickness of 1.5 to 2.5 mm. This component is designed for horizontal or vertical direction changes with standard angles of 30, 45, 60, and 90 degrees. The internal bending radius is at least twice the width of the cable tray. This design prevents excessive tension and damage to the cables. All sharp edges are deburred after fabrication, eliminating hazardous protrusions. Connection to straight trays is achieved using Grade 4.8 or 8.8 steel bolts and nuts. The load capacity of this component is equivalent to the straight section of the cable tray.

The bend structure features a single-piece formed body with internal reinforcements. These reinforcements enhance mechanical strength against shear and torsional forces. Angles are manufactured with a tolerance of ±2 degrees from the nominal angle. The hot-dip galvanized coating, with a minimum thickness of 70 micrometers, prevents corrosion. Some models include an additional polyester powder coating for corrosive industrial environments. Vertical bends risers facilitate cable passage between different levels. These components enable the installation of cable systems in complex pathways.

Cable tray supports are fabricated from hot-rolled steel profiles with a minimum yield strength of 235 MPa. The standard height of these supports varies from 300 to 1500 mm. The horizontal arm length is designed between 200 and 600 mm to accommodate different tray widths. Base metal thickness ranges from 3 to 8 mm, selected based on load requirements. All components undergo a hot-dip galvanizing process after fabrication. This coating provides an average thickness of 85 microns. The permissible load capacity per support under concentrated load reaches 1500 kg.

The support structure consists of a vertical base, a horizontal arm, and a mounting plate. The vertical base is often equipped with standard holes for 50 mm height adjustment. Connections utilize Grade 8.8 steel bolts and nuts with zinc flake coating. Suspension supports employ fully threaded M12 to M20 rods with a tensile strength of 800 N/mm². The installation spacing of supports along the route is set between 1.5 to 4 meters based on engineering calculations. This system possesses seismic resistance capabilities in accordance with IBC standards.
