Half-expanded hole perforation
Perforated sheet plates
Half-expanded hole
Half-expanded perforation hole is mostly applied in anti-slip walkways production, processing equipment and heat exchanger. Half expanded perforation holes enable liquid drainage i.e. prevent water retention, oil and other liquid materials on the walkways. Half – expanded perforation is produced in aluminum, zinc as well as hot and cold rolled mater sheets.
