THE COMPANY

Gerard Daniel Worldwide is a global leader in the manufacture of woven wire cloth (a.k.a. wire mesh) and related products, with facilities in the US, Canada and Europe. With a new 75,000 sq.ft. manufacturing facility and corporate operations located in Hanover, Pennsylvania, customers benefit from the multiple capabilities of the entire network. As the largest weaver and distributor of wire cloth, Gerard Daniel Worldwide can offer the best selection and inventory. "Global Presence, Personal Service" is the hallmark of the company, and the basis for our success. Whether your wire cloth requirements are small volume or large, our technical staff is available to help you with any questions regarding the proper selection of materials for your requirements. Look to Gerard Daniel for your electro-chemical solutions.

INDUSTRY SPECIFIC MATERIALS

Our electro-chemical meshes are used in fuel cells, batteries, and electrolyzers. Uses for the mesh include membrane or electrode substrates, current collectors, flow field screens, and gas diffusion electrodes. We offer our exclusive ColdBond™ product, which provides performance benefits to the electro-chemical industry that other woven and non-woven products can not offer.

STRUCTURAL ADVANTAGES

With our proprietary ColdBond™ process, wire cloth can be metallurgically bonded so that the wires are welded at their crossover points. This fusing enhances mesh rigidity, improves conductivity and eliminates wire fraying. These properties give woven wire cloth superior processing characteristics in tracking, mechanical strength, and eliminate dangerous sharp edges for handling that are common with expanded and perforated metals. Wire cloth thickness can be precisely controlled to provide very thin material that is ideal for electrodes.

UNIQUE VERSATILITY

Utilizing wire cloth as a current collector offers designers properties in battery and fuel cell electrodes that are not found in other grid structures. More surface area and a higher profile (knuckles) allow for better adhesion of active material and conductivity. Because the mesh is made of two separate wires, it can withstand more flexure without losing active material than alternative grids made from a single unit foil. By utilizing a mesh with open area (as opposed to a solid foil) for the substrate, a greater volume of active material per inactive material is achieved, resulting in higher volumetric power densities.
