News - Global Construction Drives Growth in PPGI and GI Steel Coil Markets

The global markets for PPGI (pre‑painted galvanized steel) coils and GI (galvanized steel) coils are seeing strong growth as infrastructure investment and construction activity accelerate across multiple regions. These coils are widely used in roofing, wall cladding, steel structures and appliances because they combine durability, corrosion resistance and aesthetic finish.

 Market Size & Growth

The global galvanized steel coil market for building materials reached around US$ 32.6 billion in 2024, and is projected to grow at a CAGR of about 5.3% from 2025 to 2035, reaching about US$ 57.2 billion by 2035.
A broader report indicates the hot‑dip galvanized steel coil segment may grow from about US$ 102.6 billion in 2024 to US$ 139.2 billion by 2033, at ~3.45% CAGR.

The PPGI coil market is also expanding rapidly, with increasing demand from construction, appliance and automotive sectors.

Key Applications Driving Demand

Roofing & wall cladding: PPGI coils are used for roofing systems, facades and cladding, thanks to their weather resistance, aesthetic finish and ease of installation.

Construction & infrastructure: GI coils are increasingly specified in structural components and building materials because of their corrosion resistance and long service life.
Appliances & light manufacturing: PPGI (pre‑painted) coils are used in appliance panels, cabinets and other metal sheet applications where surface finish matters.

 Regional Market Dynamics

North America (US & Canada): The U.S. galvanized steel coil market is seeing strong momentum, driven by infrastructure spending and domestic manufacturing. One report notes the U.S. galvanized steel coil market is estimated at ~US$10.19 billion in 2025 with a high projected CAGR.
Southeast Asia: The steel trade landscape in Southeast Asia is showing rapid expansion of local capacity and high demand for construction materials. For example, the region is acting as both production hub and high‑end import market.
In Vietnam, the building materials & hardware market is projected to generate US$13.19 billion in 2024 with steady growth ahead.
Latin America / South America / Americas overall: While less highlighted than Asia‑Pacific, the Americas constitute an important regional market for galvanized/PPGI coils, especially for roofing, industrial buildings and manufacturing. Reports mention exports and supply chain shifts impacting the region.

Product & Technology Trends

Coating innovation: Both PPGI and GI coils are seeing advances in coating systems — for instance zinc‑aluminum‑magnesium alloy coatings, dual‑layer systems, improved anti‑corrosion treatments — improving lifetime and performance in harsh environments.
Sustainability & regional manufacturing: Many producers are investing in eco‑friendly production, optimized logistics, local capacity in Southeast Asia to serve regional markets and reduce lead times.
Customization & aesthetic demand: Especially for PPGI coils, demand is rising for color variety, surface finish consistency, and building materials tailored for architectural use in SE Asia and the Americas.

Outlook & Strategic Take‑aways for Suppliers & Buyers

Demand for PPGI steels coils and GI steel coils (particularly for roofing and cladding) is expected to remain strong across North America, Southeast Asia and emerging markets in the Americas, driven by infrastructure, construction and manufacturing.

Suppliers who emphasize coating quality, color/finish options (for PPGI), local/regional supply chain, and eco‑friendly credentials will be better positioned.

Buyers (roofing manufacturers, panel fabricators, appliance makers) should look for suppliers with consistent quality, good regional support (especially in SE Asia & Americas), and flexible production (custom widths/thicknesses/coatings).

Regional variations matter: while China domestic demand may slow, export‑oriented markets in SE Asia and the Americas still offer growth.

Monitoring raw material costs (zinc, steel), trade policies (tariffs, origin rules) and lead‑time optimizations (local/regional mills) will be increasingly important.

In summary, whether it’s PPGI (pre‑painted galvanized) steel coils or GI (galvanized) steel coils, the market landscape is positive — with strong regional momentum in North America and Southeast Asia, alongside broad global drivers of infrastructure, sustainability and finishing demand.
