The break is made from a flat surface that you set the metal on, and a clamping bar, with will hold the material firm during the bend. The clamping action may be manual (hand operated) or automatic (using electric or hydraulic system, as in a press brake. The front plate of the machine is hinged, and may be lifted, bending the material over a straight edge. You can make bend at any angle up to 120 degrees.
Brakes vary in width from 18” to over 8’ for industrial use. The breaks also can be manual (hand brake) or automated (press brake). They also vary in size depending on the gauge and type of metal you are bending. Obviously, it would be hard to bed ¼” steel by hand, but 1/16’ steel, or almost any aluminum sheeting can be bent by hand.
Small Sheet Metal Brake
A small sheet metal brake would be defined as a 18”-48” brake designed for thin or soft metals. It would be hand operated, and work well for home or small business applications. Small sheet metal brakes are often portable and can be used on a table top, or have attached legs. (See “portable sheet metal brake” for more information.)
Portable Sheet Metal Brake
When working in roofing or siding, a sheet metal brake is a must-have business tool. People who have hobbies that require metal work (such as car racing) will also find a metal brake is essential to have. Since roofers and siders will need to have the sheet metal brake at the site, it is important that they have a portable sheet metal brake. A large, hydraulic, brake is unreasonable to move from site to site. The portable models can be moved easily because they are manual, can only bend thin, lightweight metals, and are generally 2-4’ in width. They are lightweight, and may or may not have detachable legs.
When shopping for a good portable sheet metal brake it to know what you are getting before you actually make the purchase. Some new models will weigh only 50 lbs, while others can weigh as much as 200 lbs, which makes them not so portable. Be sure to ask questions before you make a purchase.
Sheet Metal Hand Brake
The sheet metal hand brake is simply a brake that is operated by hand rather than having an electric or hydraulic motor to hold or bend the metal. Most are portable and lightweight. These types of breaks are inexpensive and will suit most home, siding, roofing, and hobbyist needs.
Sheet Metal Press Brake
This type of brake is used for heavy duty applications. This includes either extremely wide metals, or heavy metals such as iron or steel, which will require much more ft/lbs of pressure than can be applied by hand. They are not portable, and are typically used in industrial manufacturing applications. The bends are usually created by a hydraulic system. Unlike the sheet meal hand brake, these types of brakes have many moving parts, motors, and hoses that require much more maintenance, often by trained mechanics or engineers. These type of brakes are not practical for home or small business use, and are expensive.
The most popular metal brake listed on Amazon.com is a Malco 48” portable metal brake. List price on this brake is $380, but you can purchase it for under $290 on Amazon.com.

Sheet metal brakes vary in size, weight, and purpose. You can find portable sheet metal brakes for when you need to be able to take the brake to the work, or you can find sheet metal press brakes for when the work is heavy duty. You can find small sheet metal brakes for home use, and they are typically hand operated. The sheet metal hand brakes are great for lightweight metals, where your power is all the power you need to bend the metal. Whatever your intentions, make sure you do your research before you purchase. Make sure the “portable” model you are looking at is light enough to make it truly portable. Make sure the rating on the brake is for the gauge metal you need to bend.
