An aluminum ladder is a series of vertical steps made of high tensile metal that does not chip or crack even with severe impact compared to other ladder materials such as wood. It is generally tough, can take on daily wear and, and requires little or no maintenance. It does not need a protective finish, as it does not dry out with sunlight exposure or weather with age. It is long lasting and durable, making it ideal for utility purposes. It is available in different heights and widths.
Types of Aluminum Ladders
Kinds of Aluminum Ladders include the following:
Solid beam aluminum construction
This type of aluminum ladder is made with a solid side rail beam construction and aluminum rungs connected at regular intervals.
The rungs are connected to the side rails by extension plugs or welded joints.
The extension plug method involves pinching the rungs tightly to the internal back-up plates and side rails, making rung replacement and tightening easy.
The welding method, on the other hand, requires re-welding the rungs in case of wear and tear. Since the joints are welded together, loose rungs are never a problem.
Aluminum truss construction
This type of aluminum ladder is very similar to a wood truss construction, except that the top and bottom rails are connected to the rung assemblies by rivets instead of bolts and glue.
The rungs are connected to the side rails by welded joints or extension/expansion plugs.
An aluminum ladder with a truss construction allows a greater side beam height and carrying capacity.
Choosing Aluminum Ladders (Buying tips)
Proportion: If you want to get a tall aluminum ladder, make sure the side rails have increased sizes to provide adequate balance and load capacity.
Treatment: Choose an aluminum ladder treated with anti-oxidation properties to prevent or reduce corrosion.
An aluminum ladder conducts electricity and heat very rapidly, so make sure it is far from heat or electricity sources.
Do not expose an aluminum ladder to fire even for a brief period as it can become annealed, weakening its tensile strength and reducing its load capacity.
