Material
Ladders are made from a number of different materials, each having its own uses and limitations.
The different materials are:
Aluminum
Fibreglass
Wood
Steel
Aluminum
Aluminum is the most common material in ladders. Ladders made from aluminum are lightweight,
moisture and corrosion resistant. Aluminum conducts heat and electricity; therefore, it should not be
used where either of these conditions exists such as for electrical work.
Fiberglass
Fiberglass is an engineered or man-made material that consists of strands of high-strength glass fibres
that are encapsulated in a resin matrix. Fibreglass is a non-conductor of heat and electricity and is
moisture and corrosion resistant. Fibreglass ladders are heavier than aluminum ladders. Fiberglass
ladders should be used for all electrical work and where accidental contact with electrical wires may
occur.
Wood
Wood is a natural material and was the most popular choice before the introduction of aluminum and
fibreglass ladders. Wood ladders are heavier than aluminum or fibreglass ladders, and because it is
a natural material, will have some variations in strength, and can also splinter, rot, warp, and absorb
moisture. Wooden ladders are non-conductors of heat and electricity when kept clean and dry. Wooden
stepladders do not usually come equipped with non-slip feet, and therefore should not be used in
workplaces. Wood ladders must not be painted because it may hide critical flaws and cracks.
Steel
Steel ladders can be very heavy, but are designed to meet specific load requirements. They conduct heat
and electricity; therefore, should not be used in these conditions. As well, steel is susceptible to rust and
corrosion.
