There are different types of Steel cross arms including alley arm, cross arm braces, cross arm bracket, electrical cross arm, power pole cross arm, and v cross arm.
The function of the steel cross arm is to support distribution transformers, fuses, isolating links, and other line equipment.
Steel cross arms of different configurations are used on overhead lines, transmission towers, transmission lines, wood poles, utility poles, power poles, and light poles.
To make the steel cross arm more stable, there will be two cross arm braces to support the main cross arm by delta connection.
Rax Industry Steel cross arms in overhead lines mainly support the overhead line and the many holes on the steel cross arm are used to connect the other pole hardware fittings. The cross arm in the transmission line is used to support the transformer. The cross arm on the power pole or on the light pole is used to support the insulator by double arming bolt or u bolt.
The types of steel cross arms are different in each country. As a professional manufacturer, supplier, and exporter, Rax Industry can support all sizes of steel cross arms, we also can do the new steel cross arm design according to your unique drawing.

The raw material of the steel cross arm includes angel steel, steel brace, and U channel.
The tensile strength of the steel cross arm is more than 430/510N/MM2. The raw material is tested by Rax Industry QC team before using it. The finish of the steel cross arm is hot dip galvanized.
The angel steel includes equal leg angle and no equal leg angle. The mainly used size of the steel angle is 38*38*6.35mm, 45*45*4.75mm, 75*75*6mm, 70*70*8mm, and so on.
Some long steel cross arms are welded with short steel cross arm, steel rod or short steel flat. There are many different shapes of Rax Industry steel cross arms. Some steel cross arms are cut on the edge to a certain shape other steel cross arms are welded with a U bolt in the middle of the cross arm. Different markets have different designs on the steel cross arm. As the leading cross arm manufacturer, Rax Industry is experienced with different market requirements.
Also, Rax Industry uses hot-dip galvanize technology. The hot dip galvanized steel cross arm will get no rust. Even in continuous outdoor use in tropical areas at altitudes of up to 2200mm above sea level, the hot-dip galvanized steel cross arm surfaces have no change.
Even for specific customer requirements on the steel cross armhole size, we keep accuracy to 1mm. Rax Industry uses an automatic cross arm machine to do mass production.
