Why Rax Industry is Trusted By 1000+ clients
Indonesia market uses the pole line hardware including as below:
Cross arm 1830 and 2440, alley arm, steel brace, square head machine bolt, Bolt Eye, Stay Rod, Stay Plate and so on. These electric power fittings are mainly used to connect and support the line. The finish is hot-dip galvanized
- Quality control:
- Dimension/Drilling: All steel items to be shaped, dimensioned and drilled to the specified drawings.
- The steel tubes used on the street light arm to be constructed as per EN10255. All open ends of tubes to be internally chamfered 45 to half the wall thickness in order to reduce cable scarfing.
- Tolerances: Tolerances on the length of all members to be +2mm. Tolerances on circular hollow sections are to be in accordance with EN 10210-2.
- Galvanising
All steel members are to be hot-dip galvanized according to EN ISO 1461 andshall withstand the tests set out in this Standard. Following necessary treatment and after all sawing, shearing, drilling, punching, grinding, bending and machining are completed, the mean coating thickness (minimum) and local coating thickness (minimum) shall be as specified in Table 3 of EN ISO 1461.
The method of Steel treatment prior to galvanizing to be specified and full description to be given. All bolts and nuts to be hot-dip galvanized as well. The zinc coating to be uniform, clean, smooth and as free from spangle as possible. The zinc coating thickness shall be as specified in Table 4 of EN ISO 1461.
- Welding
Welding shall be carried out in accordance with EN 1011-1. After welding and before galvanizing, welds shall be thoroughly cleaned to remove slag and spatter, particular attention being paid to the toes of welds and to the prevention of entrapment of slag and spatter. Sandblasting or other methods of cleaning welds.

Alley arms, cross arms mounted to one side of the pole, require rigid bracing to insure proper alignment of power distribution and transmission lines. Sturdy MPS angle steel alley arm braces mount at a 45-degree angle and come complete with a solidly welded lineman step.
These braces are mounted to the side of the arm by a machine bolt and attached to the pole with two 1/2″ lag screws.
