Looking for durable aluminium window and door frames built to withstand tropical climates? ALCA Metals manufactures finished aluminium frame products directly from its own extrusionfacility in North Sumatra, Indonesia, ensuring consistent quality from billet casting through finalfinishing. As an integrated aluminium extrusion manufacturer operating since 1985, ALCA Metals understands what residential and commercial developers need: frames that resist rust, requireminimal maintenance, and still deliver a clean, modern look across housing complexes,apartments, shophouses, and office buildings. Unlike timber frames that warp or steel frames prone to rust, ALCA Metals’ aluminum window frame
and aluminium door frame products go through industrial-grade anodizing and powdercoating, giving them strong resistance to humidity, rain, and direct sun exposure. Precision extrusion profiles also ensure tighter seals during installation, improving water and air resistance while supporting better energy efficiency in air-conditioned spaces.
