How to Bend Rebar Professionally – Helpful Tips For You
Always wanted to add few structures to your home yet seemingly anxious about the piling costs you would potentially incur? When you think about it, there will always be limitations unless you step out and do some of the work yourself. Technically, the hard work would not actually be as hard as you imagine it. Yes, even in construction! It only takes a little determination and self-will to get started.
This article is designed to help you how to bend rebar professionally. The term rebar is used to pertain to pieces of steel reinforcing bars that are essential in building structural support for concrete work. It is an uncomplicated material taking a rod or stick shape and is very common in arts, landscaping, and other projects requiring metal pieces that are easy to bend.
Some steel bars, however, come in large diameters, which means bending them would require some specialized equipment before installing them. Whether you are bending a common “#4” rebar at ½ inch diameter or those of larger ones, you have come to the right place for clever ideas.
1. What You Will Need
There are two methods you can apply in bending a rebar: (1) professional bending that would require some specialized equipment or (2) bending it without professional equipment. The first thing you need to do is to check the grade and size of the rebar you are about to bend for you to know the kind of method and equipment you would need.
1.1. Method 1
For the first method, you would be needing a manual bender for a cheap yet portable bending solution. This equipment can only stand lower-grade steel and sizes. You may also want to explore the possibility of getting a power bender to achieve the most perfect hooks and bends. This will practically cause a little bit than the former equipment but it can handle any size or steel grade.
1.2. Method 2
For the second method, make sure to have a personal protective equipment. Your safety gear would have to include eye goggles and gloves. To protect your arms and legs, wear long sleeves and pants. You would also need a vise and a steel pipe. As you begin your process, choose a workplace in an open space where not many people are in the vicinity.
2. How To Bend Rebar - Getting Into Work
2.1. Save Up with Manual Benders
First You need to understand some structural issues that would potentially come with manually-bent rebar so as to avoid them. Bending a metal naturally weakens it, however, when it is done correctly, damages can be minimized and still achieving the shape you desire for your final project. Always be mindful of the size and grade of the bar you are bending and examining it against any equipment you will be using to get the job done. Bear in mind that a rebar bent is not to be re-bended because continually working it will practically lower its strength.
2.2. Rebar Power Benders
Power benders are either electric or gasoline-powered motors that are very indispensable if you need a lot of immediate bends that are of standard length. Many benders come with cutters, which allow you to sheer long bars. Now don’t freak out too easy, although it may come expensive amounting up to $ 3,000 – 5,000, this specialized equipment is very essential for big construction personnel who would need frequent and precise rebar bending. To start using, simply turn it on; set your preferred angle and length; and put in the rebar. This equipment can take in rebar of any grade and size.
After bending, you would have to recoat any epoxy or galvanized-coated rebar since molding or shaping the steel oftentimes lead to flake off or chipping on the coating. Just a little check-up and touch-up would solve the issue. You’re all done!
3. Bending Rebar without Expensive Equipment
3.1. Wear your personal safety gear
Rebar can be sharp and could carry a significant weight, thus, always make sure you wear your protective equipment, at a bare minimum are goggles and gloves. You can also wear long sleeves and pants to ensure that your arms and legs are protected as well as a pair of sturdy boots.
- Helpful Tip
Wear sturdy and old long sleeves and pants. Rust and other metal particles maychip off during the process of bending. You don’t want your new clothes to fall victim to stains.
3.2. Set up your work station
Bending rebar is best handled in a large open area with little to no obstructions as they usually come in very long rods (normally 8-20 feet and reaches to 40 feet in length).
- Helpful Tip
Try checking your backyard or any nearer open space. Please keep in mind that the lesser people there are in the vicinity, the less likely accidents will happen as you do this process.
3.3. To be bent by hand, you need to choose a piece of rebar that is reasonable in size
For smaller projects needing to be bent into different shapes, you can opt for a thinner rebar such as a ¼ inch design. Remember though that there are significant structural codes to be followed in construction which means that for projects beyond arts, they type of rebar is not purely up to choice.
- Helpful Tip
Make sure that the rebar you will be bending is proportional to the method you will be employing. You don’t want to waste any time in bending a rebar that actually needs more than just bending it by hand.
3.4. Never heat rebar to bend
It is a reality that the issue of whether heating rebar can help in bending it or actually produces danger and consequences remains a little bit of a debate. For safety purposes, abide by the principle, “If it is non-weldable, don’t heat it up.”
- Helpful Tip
Always remember, SAFETY FIRST. Don’t risk experimenting when your safety is at risk.
3.5. Place the rebar into a vise
Make sure your vise is securely anchored to your work bench. Line up your future bend with the end of the jaws. Hold one side of the vise in place and pull down on the opposite end to bend the rebar. As the rebar is being held in place by the vise, it bends just where the vise stops and then the “free” segment of the bar begins.
3.6. For easier hold and bend, place a steel pipe around the free section of the rebar
The longer the pipe you use, the better leverage you can acquire on the rebar. You will only need lesser power to bend your rebar provided that your lever is longer or that there is more free area outside of the vise.
3.7. To bend the bar, put a slow and even pressure on it
Press down on the steel pipe slowly and carefully until you reach your desired bend. Depending on the kind of project you have, you can also cut and carve wood blocks to bend around the rebar for your desired shape.
3.8. Never use hitting as a way of bending a rebar
You will have no control over the final shape of a rebar once you create a sudden impact over it such as using a sledgehammer. Worse, over bending actually creates damage over the steel surface which may lead to breaking of failing of the bar.
- Helpful Tip
If you fail to plan, you’re planning to fail. Make sure that before you make any rebar process, ensure the method you will be using so as not to waste your time or put the final shape of the rebar in jeopardy.
