Specifications
Expanded metal walkway grating is an extremely common application for expanded metal panels. The raised bonds and strands provide stronger supporting capacity than the original steel platform. With
different weight per square foot and the shapes of the diamond pattern, expanded metal walkway grating yields different strength to weight ratio for various industrial and commercial situations.
Compared with bar grating, expanded metal grating has the advantages of anti-slip effect, heavy bearing capacity, and is especially safer for women in high-heeled shoes. Engineers regard it as an
excellent choice when safety and conformance to standards is crucial criteria.

Platform
Expanded metal platform can be used to support both objects and human beings. For the purpose of skid resistance and space saving, most of clients prefer expanded metal platform. Furthermore,
expanded metal platform, being not unravel and having the capacity of heavy bearing, is strongly recommended. General expanded metal platform consists of expanded metal panels, U-edges and posts.
A expanded metal panel used as platform for supporting billboard.
EMWG-02: Expanded metal platform for supporting billboard in a high altitude.A red coated expanded metal walkway grating be used here upon stream as ridge.

Installation procedures (for platform, stair treads and ladder rungs):
For maximum load, position long way of design parallel to the clear span. LWD must be installed parallel to span. Butt or overlap one half of design. No increase in overall thickness.
Bolt or welded every 6 inches or every fourth design to rigid supports.
Install with straight edge up (top-straight edge, bottom-rounded edge). Bonds of adjoining should shape in same direction and align with adjoining pieces.
Picture here shows walkway should be installed with supporters, bolt and their proper position.
EMWG-06: Install your expanded metal walkway according to instructions.
