Description
PPGI Metal Deck – Prepainted Galvanized Floor Decking Sheets Supplier
Detailed Product Description
PPGI (Pre-painted Galvanized Iron) Metal Decking Sheets are formed by roll-forming high-quality color-coated galvanized steel coils into structural corrugated floor panels. These metal decks act as both a working platform during construction and a reinforcement member once the concrete cures.
The pre-painted surface adds corrosion resistance and visual appeal, making it ideal for exposed installations or buildings where aesthetic finish matters. Unlike traditional galvanized decking, PPGI metal deck combines structural integrity with surface protection, offering dual performance in one product.

Key Features of PPGI Metal Deck
- Corrosion Resistance
The dual protection of zinc coating and color paint extends the lifespan of the decking, even in humid or industrial environments. - Aesthetic Appeal
The colored finish enhances the visual quality of the interior or exposed surfaces, eliminating the need for painting or ceiling finishing. - High Load Bearing Capacity
Engineered profile designs offer excellent structural performance for both construction loads and in-service conditions. - Time & Labor Saving
PPGI metal decks act as permanent formwork, reducing the need for temporary support and speeding up installation. - Fire-Resistant Coating Options
Available with fire-rated coatings to meet local building regulations. - Customizable Solutions
Thickness, color, length, and profile shape can be customized to suit project requirements.
Applications of PPGI Metal Deck
PPGI Metal Deck is widely used in:
Multi-story commercial and residential buildings
Steel structure factories and workshops
Shopping malls and exhibition halls
Airports and metro stations
Warehouses and logistic centers
Car parks and mezzanine floors
How to Choose the Right PPGI Metal Deck
When selecting a suitable PPGI metal deck for your project, consider the following:
Load Requirements: Heavier loads require thicker decks and higher-profile designs.
Span Length: Choose decking that meets your span and support spacing.
Environmental Conditions: Opt for PVDF or SMP coatings in harsh environments for longer service life.
Fire Ratings: If local codes require, select decks with fire-resistant paint systems.
Color Matching: Choose colors that match your architectural design or company branding.
Budget Constraints: PE-coated decks are cost-effective; PVDF offers premium durability.
Frequently Asked Questions (FAQ)
Q1: What’s the difference between PPGI metal deck and regular galvanized deck?
A1: PPGI metal deck includes a color coating layer in addition to zinc, providing better corrosion resistance and appearance. Galvanized deck only has a zinc layer.
Q2: Can you customize the profile or shape of the deck?
A2: Yes, we offer OEM/ODM services and can roll-form custom deck shapes based on your project design or drawings.
Q3: Is the PPGI metal deck suitable for outdoor use?
A3: Yes, especially with SMP or PVDF coatings which resist UV, rain, and corrosion.
Q4: How is the deck packed for international shipment?
A4: The decks are stacked, bundled with steel straps, and wrapped with waterproof paper for sea or land transport.
Q5: Do you provide technical support or span/load tables?
A5: Absolutely. We provide load-bearing charts, CAD drawings, and installation guidance upon request.
