Hey there! I'm a supplier of metal rulers, and you might be thinking, "Why would a supplier talk about the disadvantages of their own products?" Well, I believe in being honest with my customers. Understanding both the pros and cons helps you make a well - informed decision. So, let's dive into the downsides of metal rulers.
1. Weight and Portability
One of the most obvious drawbacks of metal rulers is their weight. Unlike plastic or wooden rulers, metal rulers are quite heavy. This can be a real pain if you're someone who needs to carry your ruler around a lot, like a construction worker or a student. You don't want to lug around a heavy ruler in your toolbox or backpack all day.
For example, an Aluminum Ruler, while lighter than some other metals, is still heavier compared to a plastic one. If you're on a long - day job site and have to move around constantly, that extra weight can add up and make you feel fatigued. And if you're a student commuting to school, a heavy ruler in your bag can just be an unnecessary burden.
2. Cost
Metal rulers generally cost more than their plastic or wooden counterparts. The materials used in making metal rulers, such as stainless steel or aluminum, are more expensive. Also, the manufacturing process for metal rulers is often more complex, which further drives up the cost.
A Stainless Steel Ruler is a high - quality option, but you'll have to pay a premium for it. For someone on a tight budget, like a beginner artist or a DIY enthusiast just starting out, spending a lot on a ruler might not be feasible. They might prefer a cheaper plastic ruler that can get the job done for basic measurements.
3. Corrosion and Rust
Metal rulers are prone to corrosion and rust, especially if they're not made of high - quality materials or if they're not properly maintained. If you expose a metal ruler to moisture for an extended period, it can start to rust. Rust not only makes the ruler look bad but can also affect its accuracy.
Take a regular steel ruler for example. If you leave it in a damp environment, like a basement or a tool shed without proper ventilation, rust will start to form on its surface. Once rust sets in, it can eat away at the metal, causing the markings on the ruler to fade or become inaccurate. Even a Stainless Steel Cork Backed Ruler, which is more resistant to rust, can still be affected if it's constantly exposed to harsh chemicals or extreme humidity.
4. Brittleness and Breakage
Contrary to what you might think, some metal rulers can be quite brittle. When dropped from a certain height or subjected to a sudden impact, they can crack or break. This is especially true for rulers made of harder metals.
For instance, if you accidentally drop a thick metal ruler on a hard floor, it might develop a crack. Once a ruler is cracked, its accuracy is compromised, and it's no longer reliable for taking precise measurements. And replacing a broken metal ruler can be costly, as we've already discussed the high cost of these rulers.
5. Conductivity
Metal is a good conductor of heat and electricity. This can be a disadvantage in certain situations. If you're working in an environment where there's a risk of electrical shock, using a metal ruler can be dangerous. For example, an electrician working on live wires should avoid using a metal ruler as it can conduct electricity and cause harm.
Also, in a hot environment, a metal ruler can become extremely hot to the touch. If you're working in a factory where the temperature is high, picking up a metal ruler can burn your hand. This is something that you don't have to worry about with plastic or wooden rulers.
6. Marking Wear
The markings on metal rulers can wear off over time, especially with frequent use. When you're using a metal ruler to draw lines or make measurements, the friction between the ruler and the surface can gradually wear away the markings.


This is a problem because once the markings are faded, it becomes difficult to take accurate measurements. You might end up making mistakes in your work, whether it's in construction, art, or any other field that requires precise measurements. And replacing a ruler just because the markings have worn off can be an added expense.
7. Difficulty in Cutting Soft Materials
Metal rulers are not very suitable for cutting soft materials. The hard surface of the metal can cause the soft material to bunch up or tear when you're trying to cut along the ruler. For example, if you're trying to cut a piece of fabric or a soft foam board, a metal ruler might not give you a clean cut.
In such cases, a plastic ruler with a smooth surface would be a better choice. It allows the cutting tool to glide smoothly along the ruler, giving you a more precise and clean cut.
Should You Still Consider Metal Rulers?
Despite these disadvantages, metal rulers still have their place. They are more durable in the long run compared to plastic rulers, and they offer better accuracy for precise measurements. The high - quality materials used in metal rulers make them a reliable option for professionals who need a ruler that can withstand heavy use.
If you're in an industry where precision is key, like engineering or architecture, a metal ruler might be worth the investment. And if you take good care of your metal ruler, you can minimize the problems associated with corrosion and marking wear.
