The History of Ladder

To most people, ladders may seem like a simple object with a basic intended use – you go up them, you come down them. But what many don’t realize is that nowadays, each ladder available on the market is specifically designed for a certain type of job or function.

For example, platform ladders are ideal for do-it-yourselfers as they feature a platform to rest tools and equipment on, whereas double sided step ladders are designed for construction or home work.

Step Ladders have been around in some from or other since the beginning of time.Before the 20 th century, ladders were mainly made of wood, but obvious problems came in the form of rotting and decay, as well as conductivity while wet. While wood is still used to construct various types of ladders such as attic and loft ladders, it is rarely used for ladders that are destined for outdoor work.

But modern innovation has make them evolve into highly practical tools for use around the home and also in industry.

Aluminum step ladders became the next big thing to hit. These are extremely strong and weather-resistant and can take the hard workout that often comes with commercial use. But with these great benefits came two downsides – aluminum conducts electricity, making it unsuitable for electrical work, and it also buckles and becomes unusable after it has been exposed to heat.

Fiberglass ladders are the current darling of the ladder industry. They possess all the finest qualities in one product, making them ideal for most kinds of work. They don’t conduct electricity; are lightweight; and are sturdy.
