Expanded Grating

Aluminum is ductile and with good extensibility, so it can be stretched and expanded. Expanded grating is made from aluminum 6063. After melting and extruding, the aluminum ingot becomes aluminum profile. Different from aluminum grating, the expanded aluminum profile shall be expanded before aging, cause  aluminum becomes tough which could be broken when expanding after aging.

HY Expanded Grating is the most practical and economical product, it is born to have the knurled surface, no need to serrate it. Aluminum expanded grating is called diamond grating walkway as its diamond and serrated&knurled surface. Its beautiful appearance with knurled surface makes it popular in many industrial areas requiring non-skip features. By stretching the pre-punched extrusions, the expanded grating has knurled, diamond-shaped holes, which make it sparkling and beautiful. Knurled expanded grating is also called safety grating, usually used in roof safety systems and used as walkway grating. They are usually used after cutting and banding. We provide expanded walkway with 13mm, 22mm, 30mm and 40mm thickness.

For installation, the most recommended method is using clips. This method is applied to kinds of walkways or roof tops. Another method is welding like aluminum grating. Other methods as per customers' requirements are available.
