Anthracite Grey Roll of Steel Vent Mesh

What is soffit vent mesh used for?

Soffit vent mesh is used to provide continuous ventilation at roof eaves, cavity walls and cladding base details. It allows airflow into roof voids and wall cavities while preventing birds, insects and debris from entering.

Can this vent mesh be used for roof eaves ventilation?

Yes. It is specifically designed for roof eaves ventilation and over-fascia detailing in pitched roof construction.

Is it suitable for cavity wall ventilation?

Yes. The perforated steel design makes it suitable for masonry cavity walls, timber frame construction and steel frame systems where continuous airflow is required.

What material is the mesh manufactured from?

It is manufactured from structural grade DX52D steel.

Plain galvanised: 0.57mm thickness with Z275 coating.
Colour coated versions: 0.64mm thickness with Z275 metallic coating and 50µm + 50µm double-sided paint system (SSAB GreenCoat RWS Pro).

What does Z275 mean?

Z275 refers to a zinc coating weight of 275 grams per square metre, providing corrosion resistance for external applications.

What is the thickness of the mesh?

Plain galvanised: 0.57mm
Colour coated (GreenCoat RWS Pro): 0.64mm

The colour coated option uses heavier gauge steel for added rigidity.

Can the mesh be bent on site?

Yes. The mesh can be bent to suit installation details such as fascia transitions, cladding returns or cavity closers. It should be bent carefully using appropriate tools to avoid damaging the coating.

Can it be cut on site?

Yes. It can be cut using tin snips, electric shears or suitable metal cutting tools. Care should be taken to protect cut edges in aggressive environments.

What is GreenCoat RWS Pro?

GreenCoat RWS Pro is a high-performance colour coated steel from SSAB designed for external building components such as rainwater systems and roofline products. It offers enhanced corrosion resistance and UV durability.

Does the colour coated version have a warranty?

GreenCoat RWS Pro products are supported by SSAB performance warranties when installed in accordance with manufacturer guidelines. Warranty duration depends on environment and installation conditions.

Is this suitable for exposed eaves?

Yes. The black (RAL 9005) and anthracite grey (RAL 7016) options are ideal for exposed eaves and visible soffit details where colour matching is required.

Can it be used behind steel cladding systems?

Yes. It is commonly used at the base of steel roofing and cladding systems, composite panels and rainscreen façades to maintain ventilation.

Does it prevent birds and insects?

Yes. The elongated perforation pattern allows airflow while preventing birds, rodents and larger insects from entering cavities.

How is it fixed in place?

It can be mechanically fixed using screws, nails or staples depending on substrate. Fixings should be corrosion resistant and suitable for external use.

What size rolls are available?

93mm x 30m
157mm x 20m

Why are there two width options?

The 93mm vent strip is generally used for standard roof eaves ventilation and narrow cavity closures. The 157mm cavity ventilation strip is recommended for deeper cavity walls, timber frame construction and cladding systems requiring wider coverage.

Is it suitable for timber frame buildings?

Yes. It is suitable for timber frame construction, masonry cavity walls and steel frame systems.

Can it be used for ridge ventilation?

Yes. It may be used in ridge or high-level ventilation details where a perforated steel strip is specified.

Is it suitable for commercial and industrial projects?

Yes. It is suitable for residential, commercial and industrial roofing and cladding applications.

Is the colour coating applied on both sides?

Yes. The SSAB GreenCoat RWS Pro versions feature a 50µm + 50µm double-sided coating system.

Can it be used in coastal environments?

The Z275 galvanised coating provides general corrosion resistance. In coastal or aggressive environments, the colour coated GreenCoat RWS Pro version offers enhanced protection. Always check project-specific requirements.

Can it be used as an over-fascia ventilator?

Yes. It can be used in over-fascia ventilation details to maintain airflow beneath roof coverings.

Can it be used behind fibre cement cladding?

Yes. It is suitable for fibre cement, metal, timber and composite cladding systems where base ventilation is required.

Is it compatible with steel roofing systems?

Yes. It is fully compatible with steel roofing and cladding systems, including colour coated steel sheets.

Does it meet ventilation requirements for pitched roofs?

It supports continuous airflow at eaves and cavity openings. Always ensure the overall roof design meets local building regulation ventilation requirements.

Is it rigid enough for straight installation?

Yes. The 0.57mm and 0.64mm steel thickness provides sufficient rigidity for straight runs while remaining workable for detailing.

Can it be used for insect screening at ventilation openings?

Yes. It is suitable for screening larger ventilation openings in roofing and cladding systems.

Can it be used in refurbishment projects?

Yes. It is suitable for retrofit roof ventilation upgrades and refurbishment works where additional eaves ventilation is required.

Does it require maintenance?

No routine maintenance is typically required. It should be inspected as part of general roof maintenance.

What colour options are available?

Plain galvanised
RAL 9005 Black
RAL 7016 Anthracite Grey

Why choose colour coated over plain galvanised?

The colour coated GreenCoat RWS Pro option provides:

Heavier 0.64mm steel

Enhanced UV resistance

Improved corrosion performance

Superior aesthetics for exposed installations

It is recommended where the ventilation strip will be visible.
