The benefits include durability, impact resistant, and tensile strength while being impossible to scale and difficult to cut.  (see Expanded Metal versus Chain Link video) 
Spantek’s Expanded Metal for fencing offers attractive appearance, simple maintenance, and easy installation. Expanded metal mesh is available in a variety of diamond size openings, gauges and decorative patterns that can be specifically cut to meet your requirements.

The diamond shaped mesh’s small openings and wide strands deter climbing, cutting, and tunneling. Panels are constructed of steel sheets, simultaneously slit, and stretched into a rigid, open mesh design making continuous sheets that prohibit unraveling at the strands.  Expanded metal is easily adapted to fitting on either existing frame support systems, custom-made design systems or for new and retrofits fences for commercial, industrial, governmental or institutional facilities.
