Fencing, Grating, Braais and More for Municipal Parks

City and municipal parks managers looking for a safe, cost effective method for cordoning off public parks need look no further. Expanded mesh metal products have the potential to be used in a number of park-related contexts, from providing secure barriers, being used as bridges and walkways over muddy areas to grids for braais. expanded metal is an extremely useful material. Not only is expanded metal versatile, it has a number of other benefits as well.

Elaine van Rooyen, marketing manager of leading engineering and manufacturing company Andrew Mentis, says this interest is being sparked by the confidence engendered by expanded metal’s inherent structural integrity, which is not compromised during the manufacturing process.

“No material is lost during the manufacturing process, even though the original sheet of metal can be expanded into anything up to ten times its original size,” she says. “The result is a mesh which is considerably lighter than the equivalent area of steel plate.”

Elandsfontein-based Andrew Mentis was the first company to begin manufacturing expanded metal more than 60 years ago and is today the leading supplier of quality expanded metal in a variety of sizes and materials.

The expanding process creates a network of rigid strands which add strength, while allowing free passage of light and air. The raised mesh or Mentex®, as it is called, can be put through an additional process in which the raised meshes are flattened into the same plane as the sheet of metal expanded. This is known as Flatex®.

With extensive experience in the various applications of expanded metal, Andrew Mentis manufactures both the raised and flattened meshes and the accurate selection of the appropriate mesh depends on the application at hand.

Typically, both Mentex® and Flatex® expanded metal is manufactured from high quality local mild steel, but can be manufactured from any other ductile metal. The product is normally supplied unpainted, but readily lends itself to any of the normal finishing processes such as painting, stove enamelling, plating and galvanising; any of which can be applied for the beautification of city and municipal parks.

Mentex® and Flatex® expanded metal is available in a comprehensive range of sizes, mesh sizes and thicknesses and can be fabricated in any form. The mesh can be bent, shaped to radii, angled or notched, while maintaining its inherent rigidity. It is also available in various mesh sizes, from mini meshes with small openings of 1.4 mm by 2 mm, and with a thickness of 0,4 mm, to larger meshes with 115 mm by 300 mm openings and a thickness of 6 mm.

Industries that have already recognised the benefits of this unique product and have successfully put it to work across a spectrum of applications include mining, construction and food. It is used for screens, grates, shelving, racks, protection guards, internal partitioning, burglar proofing, fencing, reinforcement, walkways, platforms and stairs, beds, garden furniture, braai grids, filters, dividers, scaffolding, truck bodies, tunnel and shaft linings, grain silos and even decoratively.

“In an industry where quality delivers a return on investment in the long-term, a big variety of customers are tapping into our extensive experience and expertise with expanded metal,” van Rooyen says. “Its uses are many and varied and are limited only by the vision, creativity and imagination of the designer. Its versatility is endless.”

Andrew Mentis’ architectural expanded metal products are widely applied in the parks industry.

These include:

  • Mentis plaster Stop:  delivers a straight-edge and finish for plaster at all openings and abutments.
  • Brickforce:  reinforcing in brickwork to strengthen walls.
  • Mentex 99 (hailguards): used as hailguards to prevent gutters from filling up with dirt, leaves and especially hail. For city officials wanting to make their parks safer, tidier and more welcoming to the public, Mentis has a number of dedicated products and trained staff available to give advice on the best and most cost-effective options available.
