Tips to Bend Metal Trim Around a Window Tips to Bend Metal Trim Around a Window

When you are putting up metal trim around your windows, you may need to know how to bend the metal to give your trim a completed look.

Tip #1 - Purchasing Your Trim

It is good to purchase metal that will be easy to bend around your windows. Aluminum usually works best, as it is easy to bend or mold. Aluminum trim will cap covers and protect the corners around your window.

You will want to measure your window to make sure that you get enough aluminum trim that it will cover the areas you need. Measure both the length and the width of the product you will need. If there was trim already installed on your window that you are replacing, measure it as a good guideline. You should also add a ¼ of an inch of extra metal at the end of each piece to compensate for any connections that will need to occur.

When purchasing your product, it is good to get a little extra aluminum so that you will be able to practice, as bending aluminum can be tricky the first few times.

Tip #2 - Using a Capping Machine

A capping machine will allow you to cut and cap the right amounts of aluminum. If you have not used a capping machine before, make sure you read all safety instructions included with your machine.

Mark the areas on the metal that will need to be bent and insert the working end of the metal into the machine, and score it when you get to the marks. Scoring the metal slightly will make it easier to bend. Bend the product with the machine, and then pull away any extra width. This process will make sure that your metal is the right length and start will a beginning bend.

Tip #3 - Use Guides

Make sure that the scored mark is very visible, as you start with the smallest bend in the window. Use guides and stops as you line up your bend, making sure that the bend is even on both sides of the bend. Bend slowly and carefully and with even pressure until you have reached the angle in the bend that you need. If additional bends are needed on the same piece of metal, make those additional bends, making sure to dry fit each piece as you go.

Tip #4 - Breaking Trim

If you need to break your trim in areas, you can accomplish it by following the same steps for measuring. It is always good with both bending and breaking your metal trim to measure at least twice. Also score it the same way you would with a bend.

If you have a hacksaw, you can use it to make any cuts, but if no instrument is available, carefully bend your trim back and forth until the metal breaks. If one is being stubborn and will not break, you can always score it again. Buff up any sharp edges after you break them.

Though it may take a little while to learn how to break and bend the metal, learning how to install it yourself should still be less expensive and more rewarding than hiring a professional.
