How much do window grilles cost in Penang?

Window and door grilles in Penang cost between RM 28 and RM 150 per square foot installed, with a standard window panel of about 4 ft by 3 ft landing around RM 350 to RM 1,200. Mild steel is cheapest at RM 28 to RM 55 per square foot, aluminium runs RM 45 to RM 90, and stainless steel is the premium option at RM 75 to RM 150.

What grille material is best for coastal Penang properties?

For seafront properties in areas like Bayan Lepas, Tanjung Tokong, and Batu Ferringhi, aluminium or stainless steel is best because Penang's salt air corrodes mild steel quickly. Aluminium does not rust and suits high-rise condos, while grade 316 stainless steel resists salt-air pitting and is the right choice for ground-floor and seafront homes where security still matters.

Does mild steel rust on Penang grilles?

Yes, mild steel rusts, and Penang's coastal salt air accelerates it so a bare painted grille can show rust bleed within three to five years. The protection is the coating: insist on a hot-dip galvanised base with epoxy primer and powder coat, budget RM 5 to RM 10 per square foot more for it, and plan to inspect coastal-facing grilles every three to four years.

How long does it take to install grilles in Penang?

Grilles are made to measure, so expect two to four weeks from accepting the quote to installation. Mild steel fabrication takes one to two weeks, aluminium and stainless take two to three weeks, and installation for a whole house is usually one to two days.
