WHAT IS SHERMESH ?

Shermesh is a metallic hexagonal grid system which is used to hold a castable lining to a sheet of metal. Shermesh resists degradation due to abrasion, corrosion, thermal and shock loads, and excessive coke buildup. It acts to retain and reinforce the castable against cracking and spalling, and to limit the propagation of damage to it.

Shermesh will greatly increase the service life of refractory beyond almost any other form of anchoring. Catastrophic rapid spalling of linings does not occur with Shermesh, since it is retained by many welds working together, unlike S-bars, Y anchors, and similar anchoring systems. Lance type Shermesh provides maximum anchoring of Shermesh, with two tabs per cell being physically interlocked with the castable. Application of refractory is quick and reliable, since slotted holes in all faces promote flow between individual cells. Shermesh is flexible, being able to conform to any radius over 8 inches. It is strong in both tension and compression, and is far less liable to injure castable installers than most competitive single anchors. Shermesh is available in in. or 1 in. depth.

For use with monolithic (single layer) linings, Shermesh is welded directly to the inside surface of the vessel and is filled with castable refractory. Shermesh can also be used with multi-component linings by spacing it away from the vessel face using studs and washers. Insulating castable is applied to the vessel surface between the studs to the specified thickness, washers are welded to the studs, and the Shermesh welded to the washers. The final layer is then gunned or packed into the mesh.

Shermesh is a superlative reinforcement and wearing surface for ordinary concrete floors, as it minimizes the possibility of long cracks and spalling. The hexagonal cells allow the outer surface of the cement to pre-crack locally, relieving stress, and allowing the material to breathe and flex without spalling. Expansion joints can be eliminated in most cases, providin a natural skid-resistant surface. When a Shermesh reinforced floor does begin to wear, the metal edges peen over, increasing the wear-resistant steel surface, while maintaining a safe, non-skid surface. Installation is straightforward on both new surfaces and retrofits. Contact P. Sherman's technical department for further information.

Uniform high quality.  P. Sherman uses a unique stamping die and clinching process. This provides tighter clinching and more uniform tolerances, saving time and money during fabrication and providing a better final lining quality.

Mesh-Plate Composites.  In addition to manufacturing Shermesh panels, P. Sherman can also provide mesh already welded to plates in the alloy of your choice, which you can incorporate directly into your finished product. Plate is cut on a CNC plasma, and mesh is attached by welding to your specifications.

Custom forming.  We can roll or form mesh and mesh/plate composite after welding. This reduces your fabrication time, eliminates wear on forming rolls and dies, and makes for a very tight contact between the mesh and plate.

Excellent Quality Control.  P. Sherman provides as a minimum, mill tests and traceability for all Shermesh and mesh/plate composites. We can also provide ASME welding procedures and qualifications for mesh/plate composites, ferrite testing and positive material identification.

Strong Technical Support  P. Sherman can supply application engineering expertise to teach your welders to install mesh properly, refractory testing services to prequalify procedures and installers, and welding engineering help to work through metallurgical and fabrication problems.
