What to consider when buying an A-frame ladder

Material of the Ladder

Aluminum is an excellent material for several types of ladders including telescoping ladder, step ladder, extension ladder and, a frame ladder because it is tough and can stay intact while resisting a lot of abuse. It is also lightweight, which is very helpful when you need to move it back and forth. 

Most aluminum in the United States is now recycled as opposed to being mined, so this material is more affordable than others. However, it can conduct electricity and is not suitable for use near electrical wires or equipment.

Fiberglass gives a really good compromise to some of the drawbacks of using other materials. A fiberglass ladder can withstand rough handling and doesn’t conduct electricity like an aluminum material. It is also very durable and can last for many years.

If you do outdoor work, fiberglass material will not reflect the ambient temperature, which means you can still grab onto it on a hot summer day or in the middle of winter.

While fiberglass is tough and durable, there are also downsides to using this type of material. First, they are a bit more expensive than other types, and second is that, after 25 feet, these ladders will start to get unwieldy.

Wood is probably the most popular and the most common choice of all types of ladders. This is because it shares many of the advantages of aluminum material.

It is affordable and readily available at any home improvement or hardware store retailer. Wood does not conduct electricity, which means you can use it anywhere safely. The downside is that it is heavy and can weigh twice as much as an aluminum ladder. Additionally, wood can quickly deteriorate if left exposed to elements.

Steel although this is not a typical choice for homeowners, you can find them being utilized in warehouses. They are resilient and can withstand heavy loads, making them a practical choice. While this material is strong, they are also very heavy and need proper storage to prevent rusting.

Plastic ladders are typically made of polyester resin and are reinforced with glass fiber. They can be a cheaper alternative that is suitable for some situations. Ladders with a plastic construction are somewhat aesthetically pleasing and are often combined with other materials to make them more durable.  As with other ladders regardless of materials, plastic ladders are also subject to OSHA and ANSI regulations.

A-Frame Ladder Usage 

Choosing the right ladder for the type of job is essential because each one has its limitations and purpose. If you need a ladder for simple tasks, a stepladder will offer a more affordable option and will help you reach up to about 14 feet. For outdoor work, if you need a tall ladder for roof jobs or guttering then a straight ladder or extension ladder will be more useful. 

When choosing, you need to also think about how often you will use the ladder. If you only need it once every few years, then renting might be a smarter option.

Length/Height Of Ladder

When deciding on the length of a ladder, it is best to consider your safety first. In general, you can reach 4 feet higher than the height of the ladder. However, that does not mean that you need to step on the top cap of the ladder. 

On extension ladders, you need to make sure you have some wiggle room. It is not a matter of getting the right length that matches the maximum height. You need this wiggle room to cover the portion that must extend beyond the height of what you are working on. You should also take into account your position on the ladder, so opt for a ladder that is about twice the height you need to reach

Ladder Duty Ratings

Duty ratings will give you a ladder’s maximum weight capacity. This refers to the total weight it can handle, including the weight of whatever you are carrying onto it. The vital part of these ratings still lies in their weight capacity, even if it indicates three general categories.


  • Type I is for industrial products
  • Type II is for commercial use
  • Type III is for household useDuty Ratings:
  • Type IAA – Extra Heavy Duty – 375 pounds
  • Type IA – Extra Heavy Duty – 300 pounds
  • Type I – Heavy Duty – 250 pounds
  • Type II – Medium Duty – 225 pounds
  • Type III – Light Duty – 200 pounds

A Frame Ladder Maintenance Tips


Some ladders may require lubrication to ensure that they can operate smoothly. It is also best to check the ladder’s locks, hooks, ropes, and hinges regularly and follow the manufacturer’s recommendations on how to care for the moving parts. Remember that following the guidelines can result in safer operations.


Ladders are sure to last for a long time due to the regulations set forth by ANSI or American National Standards Institute. However, if the ladder does become damaged, it is important to have it fixed or discarded.

If a ladder becomes unusable, OHSA or the Occupational Safety and Health Administration requires that it should be tagged as dangerous to prevent any injuries. If you are going to throw it in the trash, you have to make sure that it is fully unusable by breaking the rungs on each side and use a permanent marker and label steel, fiberglass, or aluminum ladders to make sure that no one can accidentally use it.
