Fine Mesh for Filtration
Our unrivalled range of fine expanded meshes are ideal for multi-purpose
filtration. Cost savings can be achieved when switching from perforated
or woven materials to expanded metal guazes. Finer meshes are available
as coil form, sheet or cut to size pieces.
Versatile and adaptable, expanded meshes can also be pressed, formed,
shaped and welded in-house into components for straining, retention and
filtration, utilised across a wide range of industries.
Below are examples of some of the meshes available. For more

Formed Filtration Components
A clear focus on meeting customer needs has led to extensive
experience of prototyping and new product development for
formed expanded metal filtration components. We thrive on
assisting our customers to utilise expanded meshes to solve
filtration problems, helping to reduce costs and increase
efficiency.
In-house tooling capabilities give us a leading edge in assisting
customers to develop new filtration products. We manufacture
a range of formed filtration components, from vent ridge tiles for
roof ventilation to small bullet filters for domestic heating systems.
We specialise in high volume pressings for filter retention panels
and casings and can also accommodate specialist batch work.
Given the competitive advantages of cost savings,
technical expertise and strength, meshes can be
shaped into filtration products that meet exacting
customer specifications and performance criteria.
The most common filtration products
that we produce are cylindrical tubes,
conicals, casings, filter housings,
strainers and pressed panels.
Expanded Metal Support Mesh
Expanded metal support mesh (pictured
below left) can be manufactured to
bespoke specifications to provide filter
manufacturers with the perfect solution
for adding cost effective reinforcement
to a multitude of filtration applications,
providing strength and flexibility.

Filter Panels
As standard, we currently offer made to order products
with frames and backing meshes constructed in
stainless steel, aluminium, galvanised steel and tinplate,
in thicknesses ranging from 7mm to 50mm.
Expamet filtafoil, bondina, galvanised and stainless steel
mesh are widely used as infill options. We can also
utilise any infill material you may require.
Construction
Expamet filtafoil panels
are constructed from multiple
layers of expanded aluminium
foil mesh, arranged alternately at
right angles to each other. This structure
ensures a robust, high performance filter
with low resistance to airflow.
Each layer of foil has jointless continuity, which
prevents the hazard of loose fibres and ensures strength
and efficiency.
Features and Benefits
Bespoke Solutions Available
Low Initial and Lifetime Cost
Washable and Reuseable
Proven Performance
Low Resistance to Airflow
High Efficiency
Robust Construction
Filtafoil Adhesive
can greatly enhance the performance of your filter.
Tests show that the dust arresting capacity and
efficiency of your filter are increased, prolonging
its lifespan and further protecting your environment.
Caring for your Filter
Cleaning in accordance with our recommendations
will reduce the total lifetime cost of your filter. Using
mild detergent, the Super Panel will remain robust and
effective after many washes and Economy Panels after
several washes. Stainless steel and galvanised panels
must be steam cleaned.
