What Acerotecho | Inppa does

INPPA Acerotecho is a privately-held Chilean steel roofing manufacturer founded in 1949 by Joaquín Carracedo and currently led by third-generation Patricio Carracedo. The company operates a single integrated manufacturing plant in Maipú, Santiago, producing stone-coated (gravilladas) and pre-painted (prepintadas) steel tiles, insulated EPS-core panels (Panel IN-4 Aislado and Panel Muro Aislado), industrial trapezoidal panels (PV-4), architectural louvers, and sheet-metal accessories (hojalatería), all with Zinc-Alum AZ-150 protective coating and ASTM A792 M08 compliance. Production is 100% national and supported by automation and AI-integrated processes as of 2025.

The business serves four core customer segments — residential homeowners and housing developers, industrial and commercial construction, government and public-sector housing programs, and trade professionals (architects, contractors, installers) — across Chile from Arica to Punta Arenas, covering all four macro-climatic zones. Distribution is omnichannel: all five major Chilean retail chains (Sodimac, Imperial, Chilemat, Construmart, MTS), the government's Mercado Público procurement platform, the iConstruye construction-industry portal, direct enterprise sales, a transactional e-commerce storefront at inppa.cl, and a WhatsApp-based named-advisor consultation motion.

Revenue mechanics are unit-priced hardware sales (CLP $490 to $42,000 per unit/m² depending on product tier), custom-length fabrication contracts, and electrostatic powder-coating services. A sub-brand, InppaHouse (inppahouse.cl), extends the offering into modular steel-frame housing. The company holds no disclosed patents or external institutional investment and operates with a lean 15-person headcount, relying on its long-tenured retail distribution and project-based enterprise sales to scale.
