Crossarm Braces: An Ultimate Guide for Importers

Crossarm braces play an important role in pole line hardware installation.

They make sure that electrical cross arms are strong and firm.

Therefore, you must buy high quality and reliable crossarm braces.

It is important for you to know what it is, the designs, its functionality, and specifications.

This guide will take you through all this information.

For manufacturers, you will also learn how to make cross arm braces.

Now, let’s get to that.

What is a Crossarm Brace?

Cross arm braces are pieces of pole line hardware used to offer extra support to the electrical cross arm.

There are quite many cross-arm braces manufactured using different types of material.

The primary material used include aluminum alloys, preservative – Treated Apitong wood and the most common being flat steel.

Cross arm braces

Apart from the material used, cross-arm braces are available in different sizes.

The most common formats of cross arm braces are 20, 26, 28 and 32 mm in length with a thickness of ¼ inch.

Crossarm braces are round at the end with a hole of 9/16 inch at one end and 7/16 on the other.

Why You Need Crossarm Braces

The cross-arm braces connect the electrical cross arm using bolts and nuts.

It also supports the electrical cross arm making the power pole cross arms strong.

Flat cross-arm braces are used in pairs making it a cheap means of promoting and aligning cross arms.

Power transmission

The process of hot-dip galvanization gives it a smooth finish making it resistant to corrosion.

It comes as one piece without welding different parts together that would compromise the whole section.

Main Components of Crossarm Braces

Some of the main components of cross arm braces include:

1. Flat bar with holes

Flat bars of the cross arm brace is the main components as they are responsible for holding and supporting the electrical cross-arm.

The holes on both ends allow the bolts to pass through and aid in attaching it to the pole.

The flat nature makes it easy to connect to the electrical cross arm and the pole.

Bolts and nuts

Nuts are types of fasteners which have threaded holes.

Their functionality involves the use of bolts to fasten and join different parts together.

They remain held together as the threads combine through friction, stretching, and compression.

Bolts are types of thread fasteners having a male thread on its exterior.

It is possible that you might confuse a bolt to a screw because they are closely related.

You will use a bolt with the aid of a nut to assemble different parts with no threads.

In cases where the connection might move around, the nut might become loose, so other locking mechanisms are employed.

The locking mechanisms employed include the use of jam nuts, lock washers, thread locking fluids, safety pins and castellated nuts.

Technical Specification of Crossarm Braces

Now, before buying crossarm braces, it is important to pay attention to the following key technical specifications.

Cross arm braces


Manufacturing of custom cross-arm braces requires you to provide the necessary aspects for your preferred pair.

The dimensions you will provide will depend on the kind of work you intend to do with it.

The main factors to include in the aspects include:

  • Span Inches
  • Drop Inches
  • Length from hole to hole
  • The weight of the device
  • The depth of the pole mounting hole
  • Bottom of the cross arm mounting hole
  • Size of steel

Material Type

The type of material used in manufacturing cross arm braces varies depending on the company producing it.

Some of the most common cross arm braces are of steel, wood and aluminum alloys.

The material used has to meet quite many properties such as tensile strength and corrosion resistance.

Normally, the process of hot-dip galvanization achieves corrosion resistance in steel.

Wooden materials are treated in preservatives to increase their durability.

Other materials can be painted to add an extra coat making them resistant to rust.

Finish – hot-dip galvanization

Hot dip galvanization is a process of adding an extra coating to steel so that it can be resistant to corrosion.

It involves dipping steel in liquid zinc, and the reaction gives it a smooth final finish that is resistant to corrosion.

In most manufacturing processes of cross arm braces, it comes as the last step before the material is available for sale.

Hot dip galvanization follows the guidance of ISO1461 rules that govern galvanization of steel.

Manufacturers make sure that their products conform to the rules and regulations of ISO1461.


Crossarm braces are thick enough to act as support for the electrical cross arms.

The electrical cross arms usually bare a considerable amount of weight thus the need for assistance.

Cross arm braces should be thick enough to withstand the pressure.

The thickness will vary depending on the type of material used in making the cross arm braces.

Wooden cross arm braces are often thicker than steel cross arm braces.

This is because steel is a stronger material than wood and does not require extra thickness as compared to wood.


Designing a cross arm brace depends on the desires of the customer and if the model is appropriate.

Engineers have the capability of making models and advising on the possibility of the design working well.

The factors to consider in making the designs are number and shapes of holes at extreme ends, the design of the two terms.

In most cases, the ends of the cross arm braces are curved or rounded.

The number of holes varies from one hole to three holes depending on the type of work it will perform.

Remember, holes are of different sizes and shapes depending on the type and size of bolt.

The holes on both ends vary in size as one end has a bigger hole than the other.

The most common type has holes of 9/16 inches at one end and 7/16 on the other end.

Tensile strength

Crossarm braces have an ultimate tensile strength between 410 Newtons per square millimetre and 560 Newtons per square millimetre.

The power will also vary depending on the type of material used and the thickness of the material.

Crossarm Braces Manufacturing Process

Different industries do manufacturing cross arm braces with the relevant machines required.

Design of crossarm braces

The primary raw material is carbon steel, and it might also vary depending on customers preference.

The first step is to gather the raw material to the point where steel will be measured and marked at the desired locations.

Carbon steel is hot rolled cutting it into small pieces but in accordance to the measurements stated before.

This is the process which determines the thickness of the cross arm brace cutting it into different lengths and widths.

After that, the ends are rounded giving them the most preferred shape of cross arm braces.

It is later taken through the process of punching holes to make the desired size of the holes.

The holes are made towards the end of the cross arm braces with the bolt diameter in mind.

The device is then passed through liquid zinc in a process known as hot-dip galvanization.

This process provides the steel with a smooth and elegant finish.

The extra coating makes it have corrosion resistance properties.

Manufacturing companies always keep safety measures in place as they make the cross arm braces.

They make sure that the technicians employed to put on protective gear all the time.

Step-by-step Crossarm Braces Installation Process

The process of installing cross-arm braces is quite simple even though it requires experts with enough experience.

Since the cross arms installations are on the poles above the ground, a ladder is necessary to elevate you.

The materials needed include a cross arm brace, a ladder, drilling machine, bolts and nuts for fastening and the right spanners.

The first step in every installation is gathering all the materials required for the site.

Remember to put on protective clothing to protect you from any harm.

These include a hard hat, an apron, and working or pole climbing boots.

The second step involves going up the ladder assuming it is in place.

Carry the necessary tools with you as you go up the ladder.

Measure the devices and mark the points where the holes are drilled on the pole and electrical cross arm.

With the assistance of the drilling machine make holes on the pole and the electrical cross arm.

As you are making the hole, remember to drill the true depths for the fasteners.

Put the cross arm brace in place following the measurements and the design.

Insert the bolts in position starting with the one on the pole and fasten the nuts.

Do the same to the point of connection on the electrical cross arm and attach the bolts well.

Remember it is a risky process and you have to be cautious not to cause any harm or accidents during the process.


The knowledge of cross arm braces is beneficial to you especially if you are looking into purchasing.

Manufacturers have also made it easy to identify the kind of devices you will require, and they often check before packaging.

You have to be sure of the sort of cross arm brace you intend to use before committing to make a purchase.
