Step ladders have two main different types, the swingback step ladder and the platform step ladder. The swingback step ladder is designed without a platform and often is slightly shorter when closed than a platform step ladder. The platform step ladder as the name suggests gives the user a wide platform at the top of the ladder to allow them to stand more comfortably.
When it comes to material there are typically three options, aluminium step ladders, timber step ladders and fibreglass step ladders. The most popular choice of step ladder is aluminium for trade and industrial use due to its lightweight and robust properties and fibreglass for work outside, in hazardous environments and around electricity.
