The Complete Guide to Fiber Glass Mesh: Revolutionizing Modern Construction

For over two decades as a premier fiber glass mesh manufacturer, Hebei YUNIU Technology Co., Ltd. has been at the forefront of fiberglass innovation. Since our founding in 2002 and subsequent expansion to Shijiazhuang and Thailand in 2020, we've supplied high-performance fiber mesh solutions to 3,162 customers across 128 countries.But what truly sets our fiber glass mesh for plaster and structural applications apart? Why are leading engineering firms increasingly specifying fiberglass over traditional steel reinforcement? This comprehensive guide will answer these questions while showcasing YUNIU's unique capabilities in this growing market.

What is Fiberglass Mesh Used For?

Fiber glass mesh fabric serves as a multifunctional backbone in modern construction across three key domains:

Structural Reinforcement Innovations

• Reinforces GFRC panels for facades requiring <1/4 the weight of traditional concrete  

Precast Component Enhancement  ：

•  Embedded in hollow-core slabs and architectural elements  

•  Reduces steel usage by 35% while maintaining ISO 9001-certified load capacities  

Surface Perfection Solutions  

Advanced EIFS Integration:

• Our 145g/m² fiber glass mesh for plaster prevents 80% of thermal-induced cracks in ASTM-tested exterior systems  

 Tile & Stone Backing:  

• 5x5mm mesh configuration eliminates 90% of substrate movement issues  

•  Used in 12 high-rise projects across Southeast Asia's seismic zones  

Specialized Industrial Applications  

Infrastructure Protection:  

•  Marine-grade mesh protects pipelines with 10-year corrosion warranties  

•  Roadway grids reduce asphalt cracking by 60% in freeze-thaw cycles  

• Smart Waterproofing:  

•  Serves as carrier fabric for 2mm-thick membranes in 58 hydropower projects  

What is the Purpose of Using Fiberglass Mesh?

The main purpose of using fiberglass mesh (also known as fiberglass mesh) is to enhance the crack resistance, durability and overall structural stability of building materials, while adapting to a variety of complex environmental requirements. The following are its core uses and advantages:

1. Enhanced crack resistance

Wall and gypsum board joint treatment

Used in gypsum board joints (such as lightweight partitions, ceilings), cover the joint tape to prevent cracks caused by shrinkage or vibration.

Exterior wall plastering/insulation system

Embedded in cement mortar, insulation layer (such as EPS/XPS board) or exterior wall paint to disperse stress and reduce cracking caused by temperature difference, settlement or material shrinkage.

2. Waterproof and impact resistance

Waterproof engineering

Used in waterproof layers (such as asphalt membranes, polymer coatings) such as basements, roofs, and pools to improve tensile strength and prevent deformation of the base layer from damaging the waterproof layer.

Impact protection

In areas susceptible to impact (such as garage walls and industrial floors), combined with mortar, it can enhance the surface impact resistance.

3. Reinforcement of thin-layer materials

Tile and stone paving

When paving marble and tiles, embed them in a thin layer of adhesive (such as tile glue) to prevent the base from hollowing or deformation and falling off.

Concrete repair

Used for concrete crack repair or ground leveling layer to avoid secondary cracking of the repair layer due to displacement of the base.

4. Key materials for insulation system

External insulation system (EIFS)

Lay glass fiber mesh on the surface of insulation board (such as polystyrene board), and then cover it with anti-cracking mortar to form a "soft steel bar" structure to ensure that the insulation layer is resistant to wind pressure and cracking.

5. Other industries and special uses

Filtration and screening

The corrosion resistance makes it suitable for filter screens or gas filter materials in the chemical and environmental protection fields.

High temperature resistant scenes

Some glass fiber meshes can withstand high temperatures after special treatment and are used in flues, fire partitions, etc.

Why is Fiberglass Better Than Steel?

Fiberglass has advantages over steel in certain application scenarios, mainly based on its unique physical, chemical and engineering properties. The following are the core advantages and applicable scenarios of fiberglass (such as fiberglass mesh and composite materials) over steel:

1. Lightweight (core advantage)

The weight is about 70%~80% lighter than steel: the density of fiberglass is about 2.5g/cm³, and the density of steel is 7.8g/cm³.

2. Corrosion resistance (no risk of rust)

Fiberglass is composed of inorganic materials (silicon dioxide) and will not oxidize and rust

3. Insulation performance

Fiberglass is non-conductive and is suitable for electrical equipment housings, high-voltage tower insulation layers, etc. It has a low thermal conductivity (about 0.04W/m·K, steel is 50W/m·K), which can block heat transfer and is used for insulation layers or fireproof materials.

4. Design flexibility and plasticity

Glass fiber can be woven into mesh, cloth, felt, etc., or compounded with resin into parts of any shape (such as pipes, special-shaped structures). It is highly flexible and can fit curved or complex surfaces (such as arched roofs and cylinders).

 How strong is the fiberglass mesh?

Our fiberglass mesh factory undergoes rigorous strength testing:

• Tensile strength: 3,200-4,500N/5cm (ASTM D4595)

•  Elongation at break: ≤5% (vs. 20-25% for steel)

• Peel strength: ≥3.5N/mm (EN 13496)

• Alkali resistance: ≤5% strength loss after 28 days in pH13 solution

These indicators explain why our mesh is suitable for seismic areas that require a high strength-to-weight ratio.

How to choose the right fiberglass mesh?

Selection requires evaluation of five key factors:

1. Weight Class:

• Lightweight (60-90g/m²): Interior Gypsum Board

• Medium Weight (110-145g/m²): Standard EIFS

• Heavy Weight (160-300g/m²): Structural GFRC

2. Coating Type:

• Standard AR (Alkali Resistant)

• Vinyl Coated Waterproof

• Fire Retardant Treatment

3. Grid Size:

• 4x4mm: General Purpose

• 5x5mm: High Adhesion Applications

• 10x10mm: Drainage Applications

4. Roll Size:

• Standard: 1m x 50m

• Custom: Up to 2m in width

5. Certification:

• CE Mark

• ASTM E2098

• ISO 9001:2015
