Aluminum is ductile and with good extensibility, so it can be stretched and expanded.Expanded gratingis 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.
