Expanded Metal Products

Familiar RangeSankey’s expanded metal mesh range includes popular brands such as Ornamesh®, Gridmesh®, Louvamesh™, Maximesh®, Balustmesh®, Rendalok® and Ruralmesh® formerly offered by BlueScope Lysaght.

Countless ApplicationsOur versatile product range is ideal for applications in architecture, building design, rural applications, and production of consumer products which use metal. The range includes products well suited for decorative and practical screens for privacy, and against sun and wind, and others that are ideal for fl ooring, balustrading, and security.

A Superior ProductThe manufacturing process of expanded metal mesh involves taking a fl at sheet of metal and simultaneously slitting and stretching it to form a diamond shaped hole pattern. During the process no metal is lost and the fi nal product is stronger per kilogram and lighter per metre than the original sheet of metal.

VersatilityOften incorporated as a popular architectural feature, expanded metal mesh offers the benefi ts of decoration, protection, support and security. This versatile mesh allows light, heat, and air through, while retaining its strength, forming a very strong barrier for security purposes.

VariationsIt is available in many variations which include pattern types, mesh sizes, material thicknesses (0.5-5.0mm), coatings (Uncoated/zinc-coated), material types (steel/aluminium), and weight bearing capacities.

While the diamond design may vary, this illustration shows how a solid sheet of material becomes expanded metal without waste. The result of this expanding operation is a product that is lighter per metre and stronger per kilogram than the original sheet from which it came.

Manufacturing Process

① The sheet advances between the knife one strand width beyond the lower knife.

② The upper knife presses down and forms one half of the diamond design.

③ The upper knife then rises up and ④ transverses one half diamond to the side as ⑤ the material advances another strand width.

⑥ The upper knife presses down again to form another row of half diamonds to complete the hole shape.

⑦ The upper knife rises up again, ⑧ transversing back in the opposite direction to its original starting position. The cycle continues until the sheet is completely transformed into expanded metal mesh.

LWMLWM is the distance from a point on a knuckle to a corresponding point on the following knuckle measured across the long way of the diamond shaped hole. This distance is also sometimes referred to as ‘‘pitch’’ LWM.

SWSW is the overall dimension of the expanded metal mesh sheet measured in the same direction as the short way measure (SWM).

LWLW is the overall dimension of the expanded metal mesh sheet measured in the same direction as the long way measure (LWM).

Free Air SpaceFree air space is the percentage of the viewable expanded sheet area that is space, as opposed to metal material. Approximate values are provided in the product selection chart. Values for raised expanded metal vary from lowest value at normal incidence (i.e. when viewed with the sheet held at right angles to the line of vision) to highest value at maximum incidence (i.e. when viewed with the sheet slanting so that the thickness of strand is parallel to the line of vision, thus presenting a greater free area). For fl attened meshes only the value at normal incidence is given/relevant.

GuillotiningGuillotining is an operation to cut expanded sheets to SW x LW size (within the guillotining tolerance).

1. The above table is based on the XPM Industry Standard 1001 - Testing of Load Bearing Expanded Metal (structural meshes).

2. Load capacities given in the table are for Sankey Ruralmesh spanning in LW direction over clear spans, having every fourth strand welded to support with a minimum landing of 25mm.

3. The uniform and concentrated load capacities are essentially the same for double and triple spans. Linear interpolation and extrapolation are permitted.

4. Uniform load capacity is the maximum load just prior to permanent deflection (set) of mesh. Permanent set equals span/500 or 0.80mm, whichever is greater.

5. Deflections shown in the table refer to uniform loads causing a deflection of 6mm or span/360, whichever is less.

6. Concentrated loads have been applied through a 100mm diameter plate. They correspond to a localised deflection of 10mm.

7. For large simple spans the load carrying capacity is generally governed by deflection for double and triple spans by uniform or concentrated loads.

8. A load of 102kg approximates 1kN.9. A load of 102kg/m² approximates 1kPa pressure.

General Information

CamberCamber refers to the bow in a sheet. It is measured by placing a straight edge along the concave side of the sheet parallel to LW, touching both ends of the sheet. The maximum distance between the edge of the expanded metal and the straight edge is the camber.The tolerance for standard expanded mesh is 5mm per 1 metre of length. For fl attened expanded metal it is 7mm per 1 metre of length.

Out of SquareThe nature of the manufacturing process means expanded metal sheets have a degree of out of squareness. The tolerance for out of square is a maximum of 5mm per 1 metre of length, or 10mm per square metre on diagonals. These tolerances are for both standard stock and made-to-order sizes. Sheets can be re-squared by shearing on all sides.
