PPGI Metal Deck

PPGI metal deck is roll-formed prepainted galvanized structural sheet; procurement must connect substrate strength, zinc and paint systems, base-metal thickness, profile geometry, design span, embossment, fastening and fire or composite-slab requirements.

02Product form

Specifications and dimensions

Base-metal or coated thickness stated explicitly with profile depth, pitch and effective cover width
Panel length, end cut, side lap, embossment and bearing detail
Design span, construction load, slab depth, shear studs, fasteners and temporary propping

Standards and supply condition

ASTM A755/A755M and A653/A653M for applicable prepainted galvanized structural sheet
Project structural design code and approved deck design data control capacity and composite action

Manufacturing and processing

Structural-grade prepainted galvanized coil is roll formed through progressive stands to the deck profile.
Embossing, cut-to-length, bundling, profile measurement and coating-damage inspection complete supply.

Typical applications

Composite concrete floor systems
Permanent formwork and roof deck
Industrial, commercial and logistics buildings

Quality and acceptance controls

Verify substrate grade, metallic coating and organic coating system as three separate order requirements.
Check dry-film thickness, adhesion, color, gloss, surface appearance, forming performance and back coat.
Agree color tolerance, protective film, cut-edge treatment, coil or bundle packing and dry storage before shipment.

Include in your RFQ

Substrate grade and metallic-coating specification
Paint chemistry, primer, top/back coat and dry-film thickness
Color standard, gloss and permitted color tolerance
Thickness, width or profile geometry, tolerances and quantity
Forming duty, protective film, tests and inspection document
Packing orientation, dry storage, destination and delivery term

Selection limits

A deck profile cannot be selected from sheet thickness alone; tested or calculated section properties and project loads control.
Paint and zinc coating do not replace fire design, corrosion detailing, fastener design or temporary construction stability.
