Raised Mesh (Raised expanded metal) is supplied in the condition in which it is produced on the machine where the individual strands are set at an angle to the plane of the sheet. Raised mesh is typically stronger and more robust than an equivalent flattened mesh due to the structural strength gained from the mesh bonds and strands being set at an angle. Open area / visibility through raised mesh is variable depending on the angle at which the mesh is installed / used. Raised mesh also provides excellent grip when used as a decking material fixed on top of timber boards or if a suitably heavy duty mesh is selected, it can be used as an effective anti-slip deck for vehicle ramps where dirt and water can easily fall through the mesh.
By passing the mesh through a set of heavy duty pressure rolls, the angled strands are flattened back to the original plane of the sheet. It is common that the material thickness is reduced slightly when flattened to ensure a level and even condition. Flattened mesh allows for a more consistent open area and the finished product is easier to shear to close tolerances. Fixing and welding flattened mesh is made easier due to the more two dimensional section of the mesh.
