Fiberglass Mesh – Frequently Asked Questions (UltraRebar Mesh)

What is fiberglass mesh and why use it?

Fiberglass mesh is a corrosion-resistant, lightweight reinforcement material used in
concrete slabs, sidewalks, driveways, and similar applications. It is easy to handle, non-
metallic, and does not rust or corrode over time.

Does the mesh stay flat after unrolling?

Yes. UltraRebar fiberglass mesh has no memory, so it unrolls completely flat and stays in
place without curling or springing back.

How do I chair fiberglass mesh?

Chairing is done the same way as with steel mesh. You can also lift the mesh slightly during
the concrete pour to keep it properly suspended in the slab.

Does the mesh float or sink in concrete?

Unlike steel, fiberglass mesh does not sink. Once placed and supported, it remains in
position during the pour.

How do I cut fiberglass mesh?

You don’t need saws or power tools. Mesh can be easily cut using snips, hand cutters,
scissors, or even garden shears.

Can I roll the mesh back up if I have leftovers?

Yes. Fiberglass mesh can be rolled back easily. Secure it with zip ties or tie wire for storage
and reuse.

Can I walk or drive over fiberglass mesh?

Absolutely. The mesh is durable and strong enough to be stepped on or driven over during
jobsite activity.

Does the mesh corrode or rust over time?

No. Fiberglass mesh is completely non-metallic and will not rust, corrode, or degrade when
exposed to moisture, salts, or chemicals.

Is special training needed to install fiberglass mesh?

No special training is required. Any crew familiar with conventional mesh can install
fiberglass mesh with no issues.

Can fiberglass mesh be used in exterior and wet environments?

Yes. It is ideal for exterior slabs, sidewalks, coastal zones, and wet environments due to its
corrosion resistance and durability.
