How To Cut Fiberglass Reinforcement

Hacksaw for metal

If only a few cuts are to be made, you can use a regular metal hacksaw.

The use of a hand tool gives the following advantages:

  • Every owner has a hacksaw for metal. This is the easiest and cheapest way to cut a small number of rods to tie the reinforcement cage;
  • No spraying of fine particles as is the case with an angle grinder.

Negative aspects of using a hacksaw for metal for cutting composite reinforcement:

  • Low speed of work;
  • High workload on an employee if a large amount of work needs to be done;
  • The ability to use only in individual construction with small amounts of work.

Protective mask

Sawing non-metallic rods generates fine dust, which, if inhaled, can cause allergies or illness. The mask will protect you from such troubles.

Angle grinder

When the question arises of how to cut fiberglass reinforcement for the foundation (we have already written in more detail about the material itself here), builders first of all remember in an angle grinder. This tool allows you to cut a large amount of material efficiently, quickly and with minimal effort.

The advantages of using an angle grinder include:

  • High speed of work;
  • Using an angle grinder, you can cut a bunch of bars at once;
  • Mechanized cutting does not require a lot of muscle strength;
  • Ability to use discs with any cutting edge (for metal or stone).

Before cutting the fiberglass reinforcement angle grinder, you need to take into account the disadvantages of working with this tool:

  • Cutting fiberglass with a dust-free angle grinder will NOT work. The high speed of rotation of the disk leads to the dispersion of fine fiberglass particles in the air. The air blower to cool the tool motor further spreads the composite dust. Therefore, when working with an angle grinder, you need to use eye and respiratory protection, especially if the fittings are to be dusty in the room;
  • To operate the angle grinder, you must have an electrical connection point.

In general, the cons are pretty trivial.

How to unwind fiberglass reinforcement

The fittings are supplied in coils and straight rods. Both options are valid. The rods are coiled and not deformed, as many consumers believe. The appearance of microcracks is possible only if the material is made without observing technologies. After unwinding, it does not need to be straightened. It will happen naturally.

The rebar in the coil should be unwound very carefully, especially with a significant thickness of the rods.

  • How to do it:
  • If you work alone. With pliers Separate one end of the bay and place it under something heavy enough. The main thing. Fix one end of the rod. Then waste back, gradually, Take your time, unwinding the material
  • If you work in pairs. The process will look approximately the same with one exception: one of the ends of the armature will be held by an assistant

Gloves

Composite rods have a slight glass dusting, upon contact with which, irritation may appear on the skin. Therefore, please wear gloves before handling the composite rod.

Ax

With limited means for preparing the reinforcement, an ax can also be used. He, like Boltorez, cuts the bar, which affects the state of the reinforcement in the place of the cut.

Positive points:

  • Any owner has an ax. NO need to purchase the tool separately;
  • Speed. When preparing the base for cutting reinforcement, the work can be done quite quickly.

Negative points:

  • Inaccuracy of the cut. NOT every master can accurately and strongly hit the right place with an ax to cut the composite bar;
  • Deformation of the tip of the rod. During operation, water, cement, alkalis can get into longitudinal cracks, which will lead to a violation of the technical characteristics of fiberglass and weaken the entire structure. With temperature changes, the split reinforcement inside the product will change in volume, which will lead to the destruction of concrete.

Bolt cutter

Before cutting composite rebar with a Bolt Cutter, you should also learn the pros and cons of using this tool. You need to understand that the Bolt Cutter does NOT cut the composite bar, but rather bite it, which affects the technical characteristics of the material.

Benefits of using Boltorez:

  • Does NOT require an electrical connection;
  • When working, the Boltorez does NOT form a large amount of small particles, so it can prepare rods to size indoors;
  • With the bolt cutter in hand, you can move and work anywhere (there are wires).

Disadvantages of using Boltorez:

  • You cannot cut more than 3 bars at the same time using the Bolt Cutter;
  • When working with this tool, it is necessary to use significant muscle efforts;
  • The bolt cutter is rarely on the list of household tools. To work, you will have to rent or buy it, which is economically impractical;
  • The use of a bolt cutter causes deformations of the material at the cut site (material crumbs and longitudinal crack appear at the end of the rod). Such deformation reduces the bearing capacity of the reinforcement and shortens its service life.

How to cut fiberglass reinforcement

Cutting fiberglass reinforcement is carried out by an angle grinder, as in the case of metal, only this process takes much less time than cutting metal rods, in 4.5 seconds, you can cut several fiberglass rods with a diameter of 12mm.

Cutting composite rebar with a hacksaw for metal. Cutting upon purchase

  • You do not have to look for a car and transports long rebar;
  • The reinforcement will arrive at your construction site already cut into pieces of the required length, and you can immediately start working with it;
  • You do not need to cut the reinforcement yourself and look for the necessary tools for this.

Just do not forget to calculate in advance the number and length of reinforcing bars you need.

Recommendations for the installation of fiberglass reinforcement

The production of work with fiberglass reinforcement is practically no different from working with metal reinforcement, and does not require any special skills and knowledge. These are the same reinforcing rods, only not metal, but composite, they are much lighter than metal, respectively, the installation of fiberglass reinforcement will be faster and easier, which significantly reduces labor costs.

Angle grinder and hacksaw

The most efficient, practical and accurate way to cut fiberglass reinforcement. Cutting angle grinder equipped with a standard diamond or abrasive disc. The use of a hacksaw for metal in such types of work is justified only if a small amount of work is planned. Otherwise, if it is necessary to carry out a large number of cuts, the foreman’s hand gets tired, and the productivity and quality of work decrease.

Bolt cutter and ax

As for cutting the fiberglass reinforcement with an ax and biting it with a bolt cutter. These two methods have significant disadvantages. Their main disadvantage is the negative impact on the reinforcing bar at the cut. As a result, deformation, splitting and crumbling of the material can be observed. Thus, the ends of the workpiece have a split look. Longitudinal cracking of the product, in turn, complicates its further use and reduces the service life of the reinforcement structure.

Imperceptible to the naked eye, defects that have a longitudinal character of cracking penetrate into the depth of the rod. Such cracks in the future will become a place of accumulation of alkali, water, cement, dirt, when pouring concrete into the reinforcement. They also act as capillary channels for the penetration of THESE deposits into the rod.

The main danger of such defects is at the ends of the rebar blank. Subsequent, more abundant and deep cracking of the product at strong temperature changes, at the stage of its freezing and thawing. When a concrete solution gets into cracks, the destructive negative effect of the alkaline component of concrete on the fiberglass rod increases. The consequences of such an impact manifest themselves from the inside of the reinforcing bar.

How to cut fiberglass reinforcement?

One of the advantages of using fiberglass reinforcement. The ability to cut the workpiece to the desired size, which makes production virtually waste-free. But here a completely logical question arises. How to cut fiberglass reinforcement and what safety rules should be followed at the time of cutting.

There are the following options for cutting fiberglass reinforcement:

Sawing with a metal saw;

Cutting with an angle grinder, aka angle grinder.

Precautions in the process of cutting (dividing) fiberglass reinforcement

It is important to take precautions during the processing phase of fiberglass products, including protecting the respiratory tract, eyes and hands from splinters and dust. A special protective mask, worn at the stage of cutting the reinforcement, will protect the light of the master from basalt and glass fibers from dust, which negatively affect the state of the respiratory tract. An alternative to a mask can be a respirator, which must be securely fixed on the face. Important Make sure that dust particles do not enter the respiratory tract bypassing the air filter element.

You can protect your eyes with Special glasses. Hands Must be protected with gloves. It should be noted that the thickness of the basalt-glass is similar in thickness to a human hair. In order to protect the skin of the hands from such particles, standard fabric gloves are not suitable. In cutting operations of reinforcement, cotton gloves with a latex layer should be used, and even better, silicone gloves. Ease of cutting also differs with different diameters of fiberglass reinforcement.
