Sifus,
My in laws house grill rusty after 10 yrs ( mild steel powder coat), planning to change to stainless steel 304 for their apartment. Quoted Rm 3.5K, wtf is this chop head price.?
Anybody installed these 1-2 yrs, these type i dono the market price

Security door saw many examples like not really that secure
The connection part where its openable are easily hacked
Apartment like this, still must use grill per management design
Yours quite cheap, which area?
