Choose the specification before the sheet

The first option fits a project built around a galvanized sheet plate, fish-scale opening, and defined stock or cut-to-size panel. The heavy expanded metal mesh range fits industrial orders that begin with a selected metal, hole configuration, strand size, panel width, and finish.

That difference changes the quotation process. A decorative screen may start with the visible pattern and sheet size. A machinery guard, platform, or security fence needs the opening, strand dimensions, material, and panel layout considered together. We can work from those details when you send a drawing or sample.

Material choices

The standard expanded metal mesh sheet uses a galvanized sheet plate. This gives you a direct material choice for construction mesh, protecting mesh, decorative mesh, filters, sieving, barbecue mesh, and cages.

The heavy range includes stainless steel, low carbon steel, aluminum, copper, titanium, and galvanized steel. Those options allow the base metal to be selected alongside the application and fabrication plan. For example, a galvanized steel order remains close to the standard sheet's stated material, while stainless steel, aluminum, copper, or titanium changes the material specification for the project.

State the material with the sheet thickness, opening, panel dimensions, and intended use. A material choice without the other dimensions does not define the finished panel for quotation.

Hole patterns and mesh form

The standard sheet uses a fish-scale hole shape and describes two forms: raised mesh and flattened mesh. Raised mesh leaves the strands angled to the sheet plane. Flattened mesh passes through pressurized metal rolls to create a flat surface.

The heavy range lists diamond, hexagonal, fish-scale, turtle-shaped, and fancy hole configurations. It also groups products as small, medium, heavy, and special expanded mesh. Fish-scale is the common pattern between the two options. Diamond, hexagonal, turtle-shaped, and fancy patterns are listed within the heavy range.

Mesh form affects how you plan the panel. A flattened sheet can suit a project that needs a flat surface or more surface area for welding into a frame. A raised sheet keeps the angled strand form. For a machinery guard, place the hole pattern, mesh form, orientation, and frame opening on the drawing so the fabricator can match the panel to the guard.

Dimensions, strand sizes and custom work

The standard sheet gives two reference sizes: 2440 mm LWD by 1220 mm SWD, and 1250 mm LWD by 2500 mm SWD. Stock sheets are manufactured to a nominal plus tolerance and may arrive slightly oversized. Cut-to-size panels are available, and sheared panels support dimensional accuracy, close tolerances, and sheet squareness.

The heavy range uses a broader dimensional specification. Its maximum LWD is 300 mm, maximum SWD is 120 mm, and maximum sheet width is 3.4 m. Strand thickness ranges from 0.5 mm to 14 mm, while strand stem ranges from 0.5 mm to 8 mm.

These measurements describe different parts of the product, so keep them separate on your drawing. For a stock-sheet order, give the LWD, SWD, sheet size, and orientation. For a platform or machinery guard, give the required sheet width, LWD, SWD, strand thickness, and strand stem. We can make custom specifications and OEM or ODM configurations within the stated product range.

Imagine a large guard panel being moved through a plant and fitted into a frame. The panel width and frame opening must be coordinated before fabrication. For a decorative screen, compare the two standard sheet sizes with the frame dimensions and mark whether the panel needs to be sheared square or supplied in a larger format.

Finish and installation details

The standard sheet is identified with galvanized sheet plate. The heavy range lists hot-dip galvanizing, powder coating, anodizing, PVDF, and spray painting as surface treatments.

For the heavy option, select the treatment together with the base metal and hole pattern. For the standard option, carry the galvanized material through the quotation and drawing. Do not leave the finish as a separate note if the panel will be cut, framed, or installed in sections.

Installation planning starts with the finished panel dimensions. Mark panel edges, cut locations, fixing points, mesh orientation, and the frame opening. A walkway or platform drawing should also show the panel layout and support spacing for review with the selected strand dimensions. A machinery protection drawing should show the equipment envelope and inspection clearance.

Send the access-route and frame-opening measurements with the order dimensions. That lets us check whether the ordered panel size suits the installation sequence before fabrication.

Questions to settle before ordering

Send a complete mesh specification

Select the standard expanded metal mesh sheet when galvanized material, a fish-scale opening, and a defined stock or cut-to-size sheet match the job. Select the heavy expanded metal mesh range when the order needs more metal, pattern, strand, width, or finish choices. Send the material, hole pattern, mesh form, LWD, SWD, strand dimensions, panel size, orientation, finish, frame drawing, and quantity for a quote.
