I visited to a few showroom selling security door. According to the sales people, told me that they have a few types there. Local made stainless steel grilles(thicker), china made stainless steel(thinner) and hollow metal grilles. Do anyone know what is the different between all the types above in term of the safety? Is that really make a different with using different materials?
Also, anyone using the brand of YSE before? Any comment about it?
