A ladder is now considered to be almost a necessity for any household. Whether your primary purpose is being prepared for minor home repairs, extensive construction and landscaping, or simply keeping your family safe in the event of an emergency, ladders are extremely useful around the house or in a business.
Ladders can be made from a variety of materials, some more durable than others. The most common materials from which ladders are made are fiberglass, aluminum, and wood. Aluminum is fairly durable and lightweight, but it can often corrode from prolonged exposure to the elements, or to harsh chemicals. Another issue with aluminum is its conductivity- aluminum ladders should not be used for electrical work or around anything that puts out electricity, as this creates an increased risk of electrical shock for the user. Fiberglass ladders are extremely stable and durable. They will remain usable for many years, and can be safely used around corrosive chemicals or electrical work. Fiberglass ladders also hold up well to weather, but are still lightweight enough to be transported or moved for use. Wooden ladders are also good for situations where conductivity is a potential issue and they are usually quite sturdy, but they tend to be somewhat heavier and more difficult to transport, and will also often deteriorate more quickly when exposed the elements.
Height is another factor to consider. For simple household tasks, a ladder that reaches very high up is not necessary, and may just make the ladder more troublesome to use. However, for work on trees or rooftops, it is a necessity to purchase a ladder tall enough to reach the surface you need to maintain. Ladders of improper height are often a contributing factor to many injuries and accidents in the home.
It is also wise to consider the performance rating of ladder when looking at ladders to purchase. No matter the material, different ladders carry different performance ratings, and are designed to hold different amounts of weight. For this factor, it is important to think of what your ladder might be used for. If you might be hauling hardware or paint up the ladder frequently, a higher performance rating for a higher weight is best.

Millions of people visit the Sistine Chapel each year. Their reasons for visiting that Catholic landmark are as diverse as they are. However, one aspect of the Sistine Chapel is clearly the main attraction for the majority of these visitors. Not many ceilings attract such a large volume of tourists, and yet, the ceiling of the Sistine Chapel is one of the most beautiful in the world. Painted over the course of decades by Michaelangelo, the chapel’s ceiling is one of the most recognizable pieces of art from the Italian Renaissance. While the art has a religious quality, a few simple tools were used by Michaelangelo to allow him to reach his lofty canvas. Without ladders, Michaelangelo’s art would have been impossible. In fact, much of humanity’s artistic and practical creations would not exist without ladders.
No one knows exactly when humans invented the ladder. While some references date the ladder to prehistoric times, no doubt exists as to its important functions by ancient times. In many ways, the world’s most complex civilizations based the construction of their monuments and buildings on the simplicity of their ladders. Without the use of ladders, the intricate hieroglyphic artistry found in Egyptian tombs would have been impossible. Without ladders, the construction of Greece’s Parthenon never could have happened. And without ladders, the Great Wall of China would never have reached the heights that it did during its glory days.
Overall, ladders, no matter how simple or complex, enabled humans to create art, architectural wonders, and functional buildings by allowing workers and artists to reach higher than they could on their own feet. Whether a sailor used ladders to scale the great heights of his sailing vessel in the Indian Ocean or if he worked on the palace at Versailles in France during the reign of Louis XIV, the average man frequenly used ladders. And he continues to use them in modern times.
Whether they were made of wood, rope, or metal, ladders undoubtedly helped create humankind’s constant quest to create, protect, dominate, defend, and explore. Ultimately, without the use of ladders, the majority of our most cherished structures would not exist.
