Custom Fiber Mesh for Concrete Construction

Overview

Fiber mesh reinforcement distributes tensile stresses throughout concrete slabs, reducing crack width and improving durability.

Unlike traditional rebar, fiber mesh provides isotropic reinforcement, meaning strength is uniform in all directions within the plane of the slab.

Material Composition and Properties

Common base materials include polypropylene, polyester, and alkali‑resistant glass fibers, each selected for specific alkalinity resistance and tensile modulus.

Typical tensile strength ranges from 300 MPa for polypropylene to 2000 MPa for high‑modulus glass fiber, while elongation at break varies between 15 % and 3 %.

Mesh aperture sizes are customizable from 5 mm to 50 mm, influencing concrete flow and bond development.

Manufacturing Process

Fibers are extruded, drawn to target diameter, and then coated with a sizing agent that enhances cement adhesion.

The coated fibers are woven on rapier looms to produce a uniform grid; loom tension is monitored to keep aperture variation under ±0.5 mm.

After weaving, the mesh passes through a heat‑setting oven to stabilize dimensions, followed by widthwise cutting and roll‑forming to customer‑specified lengths.

Customization Options

Buyers can specify fiber type, mesh geometry, roll width, and surface treatment to match project requirements.

• Fiber material: polypropylene, polyester, glass, or hybrid blends.
• Mesh opening: 5 mm, 10 mm, 20 mm, 30 mm, or custom.
• Roll width: 0.5 m to 3.0 m in 0.1 m increments.
• Linear density: 50 g/m² to 400 g/m².
• Edge finish: sealed, ultrasonic cut, or selvage.

Applications in Concrete Construction

Fiber mesh is placed in the top third of slab thickness to control plastic shrinkage cracking during early curing.

In industrial flooring, the isotropic reinforcement reduces joint spacing and allows thinner slabs while maintaining load capacity.

For shotcrete and tunneling linings, the mesh provides flexural reinforcement that resists spalling under dynamic loads.

Because the mesh does not corrode, it is suitable for marine structures where chloride exposure would degrade steel reinforcement.

Quality Control and Testing

Each roll undergoes tensile testing per ASTM D5035 to verify break strength and elongation.

Aperture uniformity is checked with laser scanning; average deviation must be below 0.3 mm.

Surface adhesion is evaluated by pull‑off tests on concrete cubes after 28‑day curing, targeting a minimum bond stress of 1.2 MPa.

Visual inspection ensures no broken fibers, foreign inclusions, or coating defects before packaging.

Technical Data

Frequently Asked Questions

Can dimensions be customized?

Yes. Roll width, length, mesh opening, and linear density are all specified per project drawing or sample.

What information is required before quotation?

We need the desired fiber material, target tensile strength, aperture size, roll dimensions, and any surface treatment (e.g., anti‑UV coating).

How is quality inspected?

Every roll is tested for tensile strength, aperture uniformity, and bond strength; results are recorded and available upon request.

What packaging methods are available?

Standard packaging includes polyethylene‑wrapped rolls on pallets with corner protectors; moisture‑barrier bags are offered for overseas shipments.
