Comprehensive Analysis of Galvanized Corrugated Steel Sheet

-------Materials, Applications, Profiles, and Color Solutions

Galvanized corrugated steel sheets are widely used in industrial, commercial, and infrastructure projects due to their excellent corrosion resistance, structural strength, and cost efficiency. For professional procurement managers, selecting the right base material, profile, and surface finish is critical to ensuring long-term performance, lifecycle value, and compliance with project specifications.

This article provides a comprehensive overview of common base materials, application scenarios, corrugation profiles, and color coating options for galvanized corrugated steel sheets.

Common Base Materials for Galvanized Corrugated Steel Sheets

Hot-Dip Galvanized Steel (GI)

Hot-dip galvanizing corrugated sheet is made from cold rolled low carbon steel, coating zinc by the continuous galvanizing line. They are usually conform to ASTM A653 or EN 10346 (DX51D+Z) standards.

Benefits at a glance:
Stable supply and competitive cost
Corrosion protection up to 8 years in general environment
Good formability and installation facility

Typical zinc coating: Z60–Z275 (can be customized)

 

Galvalume Steel (GL)

Galvalume corrugated steel sheets, with 55% aluminum, 43.4% zinc, 1.6% silicon alloy coating, are typically made to ASTM A792 / A792M specifications.

Key advantages:
Excellent corrosion resistance over traditional GI
Longer service life in marine, high humidity and high temperature conditions
Excellent heat reflectivity for energy-efficient building design

Common Base Materials for Galvanized Corrugated Steel Sheets

Prepainted Galvanized / Galvalume Steel (PPGI / PPGL)

PPGI and PPGL corrugated sheet is produced by applying organic coatings on GI or GL substrates, which has the structural strength of GI/GL and the visual enhancements of coatings.

Key advantages:
Extra protection from weathering and rusting
A diverse selection of colors and finishes are available.
Suitable for exposed roof and wall cladding systems

Application Scenarios by Material Type

Material Type Typical Applications
GI Corrugated Sheets Industrial workshops, warehouses, agricultural buildings, temporary structures
GL Corrugated Sheets Coastal projects, chemical plants, power facilities, high-corrosion environments
PPGI / PPGL Commercial buildings, logistics centers, industrial parks, architectural roofing and facades

Material selection should be based on environmental conditions, design service life, maintenance strategy, and total project cost.

Popular Corrugation Profiles

The design of the corrugation profile has a direct impact on the strength of the structure, effectiveness of the drainage, and ease of installation. Common profiles include:

Sinusoidal (wavy) profile
Low cost, efficient water drainage, and common usage

Trapezoidal Profile
Enhanced load bearing, perfect for large span roofing systems

High-Rib Profile
Profile height, length of pitch, thickness of sheet and width of effective coverage can all be modified to your project needs.

Color Options for Prepainted Corrugated Steel Sheets

Prepainted corrugated sheets are generally manufactured according to RAL color system.

The most popular used colors are:
Silver gray, off-white (regular industrial colours)
Blue and navy (transport, logistics and commercial buildings)
Red and multistrip red (agriculture and industry)
Green (industrial and park solutions in eco)
Coatings from PE, SMP, HDP, and PVDF are available, allowing for performance customization based on region specific climate and exposure conditions.
