Rebar Bending Machine Models Compared"},"content":{"rendered":"

The question we hear most often when someone is buying a rebar bending machine is: \u201cShould I get an 18 mm, a 24 mm, or do I need something bigger?\u201d In this article we have put Afacan rebar bending machine models side by side and explained in plain language which model suits which job.<\/p>\n

What does \u201c18 mm machine\u201d or \u201c24 mm machine\u201d mean?<\/h2>\n

What craftsmen call an \u201c18 mm machine\u201d is a machine that can bend reinforcing bar up to 18 mm in diameter<\/strong> at most. This number shows the capacity of the machine. It also bends thinner bars with ease. For example, a 24 mm machine bends 8, 10, 12, 16 and 20 mm bars alike. That is why, when choosing, you should base your decision on the thickest rebar<\/strong> in your project.<\/p>\n

18 mm and 20 mm: for small jobs and frequent moving<\/h2>\n
\"Afacan
R18 Portable Rebar Bending Machine<\/figcaption><\/figure>\n

Who is it for:<\/strong> teams building detached houses, doing renovations or small buildings, and craftsmen who bend rebar on the formwork.<\/p>\n

The R18 and R20 are portable models; weighing about 94\u201396 kg, they can be carried by two people and fit in the back of a van. Since they run on 220 V, they can also be used on sites where three-phase power has not yet been installed. They are fast and practical for work dominated by stirrups and reinforcement up to 16 mm. The R20 is the most preferred rebar bending machine in our sales records.<\/strong><\/p>\n

\"Afacan
R20: the most preferred rebar bending machine in our sales<\/figcaption><\/figure>\n

Note:<\/strong> if your project uses rebar thicker than 20 mm, these models are not enough. Constantly working at the limit of capacity also wears out the machine.<\/p>\n

24 mm and 26 mm: the workhorse of residential sites<\/h2>\n
\"Afacan
R24: the most powerful model in the portable class<\/figcaption><\/figure>\n

Who is it for:<\/strong> multi-storey residential projects and sites using 20\u201324 mm rebar in columns and beams.<\/p>\n

The R24 is the most powerful model in the portable class. Because it can run on 220 V, it can be used from the very first days of the site; a 380 V option is also available. Being both portable and capable of bending the thick reinforcement of residential projects, it is one of our most preferred models.<\/p>\n

The R26, on the other hand, is a fixed model that runs on 380 V. It is a good choice if the machine will be set up in one corner and stay there for the whole project.<\/p>\n

36 mm and 42 mm: large sites and rebar workshops<\/h2>\n
\"Afacan
R36: the choice of large sites and rebar workshops<\/figcaption><\/figure>\n

Who is it for:<\/strong> large residential and commercial projects, sites using thick rebar in shear walls and foundation reinforcement, and rebar preparation workshops.<\/p>\n

The R36 and R42 are fixed machines designed for intensive all-day work. Thanks to their more powerful motors, they bend thick rebar in one go without strain. They require 380 V three-phase power. The R36 is our second most preferred model after the R20. On large sites we often see it used together with a portable machine: thick reinforcement is bent on the R36, stirrups and thin rebar on the portable machine.<\/p>\n

50 mm: infrastructure and heavy reinforcement<\/h2>\n
\"Afacan
R50: our largest model with 50 mm capacity<\/figcaption><\/figure>\n

Who is it for:<\/strong> projects using rebar thicker than 40 mm, such as bridges, viaducts, dams and high-rise foundations.<\/p>\n

The R50 is Afacan\u2019s highest-capacity rebar bending machine. With its 5.5 kW motor it bends 50 mm reinforcing bar. In this class, the weight and robustness of the machine are important for clean, accurate bends.<\/p>\n

Starter bar bending machine: a separate machine for a separate job<\/h2>\n

A standard rebar bending machine cannot be used when starter bars protruding from concrete need to be bent in place. HB32 starter bar bending machine<\/a> was developed for this job; it bends starter bars up to 32 mm right where they are.<\/p>\n
