Why You Chose Pre‑painted Galvanized Color Coated Steel Sheets?
Outstanding Corrosion Resistance & Long Service Life
Pre‑painted galvanized color coated steel sheets use a hot-dip galvanized base with coating weight ranging from Z40 to Z275, with options of zero spangle, regular spangle, and large spangle. The double-layer protection of galvanized substrate and color coating effectively resists rain, UV rays, humidity, and mild corrosion, ensuring stable performance and long service life even in outdoor environments.
Light Weight & High Structural Strength
These steel sheets are lightweight, only 6–10 kg per square meter, greatly reducing the load of building structures and lowering transportation and installation costs. Meanwhile, the corrugated design enhances structural rigidity, with yield strength reaching 250–550 MPa, delivering good seismic resistance and wind pressure resistance for roofing and wall cladding.
Fully Customizable Specifications & Appearance
We support full customization for pre‑painted galvanized color coated steel sheets, including thickness (0.12–1.0 mm), width (200–1200 mm), custom colors based on customer samples, printed logos, and decorative patterns. Flexible customization makes them suitable for various architectural styles and project requirements.
Easy Installation & Eco-friendly Recyclable Material
The corrugated structure allows fast and simple installation, significantly shortening construction periods and reducing labor costs. As a metal building material, pre‑painted galvanized color coated steel sheets are 100% recyclable, complying with green building standards and sustainable development requirements.
Main Applications of Pre‑painted Galvanized Color Coated Steel Sheets
Pre‑painted galvanized color coated steel sheets are widely used in many construction fields:
- Roofing materials for industrial factories, warehouses, and workshops
- External wall cladding and enclosure panels
- Ceiling and interior decoration panels
- Roof and wall systems for prefabricated houses and temporary buildings
- Agricultural buildings such as barns and storage sheds
All products adopt standard seaworthy packaging, suitable for international ocean transportation and bulk export orders.
FAQ about Pre‑painted Galvanized Color Coated Steel Sheets
Q1: What is the difference between PPGI and PPGL steel sheets?
A: PPGI is pre‑painted galvanized steel sheet with zinc coating; PPGL is pre‑painted galvalume steel sheet with zinc-aluminum alloy coating. PPGI provides cost-effective corrosion resistance for general construction, while PPGL has higher anti-corrosion performance for harsh environments.
Q2: What thickness and width are available for color coated steel sheets?
A: The thickness ranges from 0.12 mm to 1.0 mm, and the width ranges from 200 mm to 1200 mm, which can be customized according to project needs.
Q3: Can we customize colors and logos on the steel sheets?
A: Yes, we accept custom color matching based on customer samples and can print logos, patterns, and graphics to meet brand and design requirements.
Q4: Are pre‑painted galvanized color coated steel sheets waterproof?
A: Yes, the corrugated design has excellent drainage performance. With professional installation and matching accessories, they provide reliable waterproof performance for roofing systems.
