CThru Metals offers a full suite of manufacturing capabilities to ensure we deliver the highest precision on your expanded metal project’s requirements.

CThru Mesh® is used in lightning strike protection for aircraft, wind turbine blades and other carbon fiber uses, batteries, electrodes, fuel cells, heating elements, filtration and a host of other applications. We work with a variety of materials, including copper, aluminum, titanium, stainless steel, exotic alloys and plastics. We meet exact specifications for thickness, strength, weight, open area and resistivity.

How It’s Made

We use precision proprietary expanding technology to cut metal foils into various thicknesses, shapes, and configurations. Your application’s requirements determine the expanded metal’s material, overall thickness and configurations.

CThru offers standard diamond sizes from 0.030”- 0.500”, with the number of openings per square inch varying from 25 to 5,000. After material is expanded, the metal’s thickness can be controlled to your needs, with a range of additional capabilities that include:

flattening expanded metal

Flattening

Flattening offers reduced thickness, a smoother surface and reduced pocket depth. This process is ideal for applications that require particular surface finish specifications.

stretching expanded metal

Stretching

Stretching changes the shape of your expanded metal’s openings. Stretching is ideal for battery, fuel cell and filtration application that require increased pocket depths for maximizing, air, liquid and composite volumes.

annealing furnace expanded metal

Annealing

Heat treatment of expanded metal foils normalizes the material from work hardening in the expanding process.

blanking expanded metal  blanking metal

Custom Blanking

By leveraging our in-house stamping capabilities, CThru Metals can stamp expanded metal sheets into unlimited geometries. Tolerance capabilities as tight as .001” ensure your parts are stamped to exact specifications.

solid sections in expanded metal

Solid Sections

CThru Metals can add solid sections to the edges or solid strips throughout the sheet of material.
