Expanded metal gratings have mainly two types: light and heavy type.
Materials for expanded metal gratings:
Aluminum, carbon steel, stainless steel and other metals.
Grating Patterns:
Diamond, triangle, scale hole, etc.
Specification: thickness:0.5mm-8mm
Hole width: 2.5mm-50mm
Hole length: 4.5mm-100mm
Openness: 0.5mm-8mm
Features:
Expanded metal grating offers many advantages over bar grating. It is made of one continuous piece of material yielding a greater strength to weight ratio. There are no welded parts and the surface is naturally skid proof without further processing. The pattern and openings provides a wider range of load capacity gratings to meet your exact requirements giving greater economy to your project.
Expanded metal grating is the most practical and economical way to assure strength, safety, and a non-skid surface, .Expanded metal grating is ideal for use on plant runways, working platforms, and catwalks as it is easily cut into irregular shapes and can be installed quickly by welding or bolting.
This metal grating offers ease of fabrication, economy, strength, safety and are available in carbon steel , stainless steel and aluminum.
Application:
As fences for walkway, tread plates, stair protection:
Walkways
Stairways
