0.3mm Bright Surface Regular Spangle Galvanized Roofing Sheet

0.3mm Bright Surface Regular Spangle Galvanized Roofing Sheet

Corrugated galvanized steel is one of the strongest, most durable roofing materials, since it

lasts longer, is more resistant to wind, and absorbs less heat than asphalt shingles.

Key Advantages

♦ Excellent Corrosion Resistance

The zinc coating forms a protective barrier against moisture and oxidation, making it ideal for

outdoor and humid environments.

♦ High Strength & Impact Resistance

The corrugated (wavy) design enhances structural rigidity, allowing it to withstand heavy wind,

snow loads, and mechanical stress.

♦ Lightweight & Easy to Install

Lighter than concrete or solid metal sheets, reducing transportation and installation costs. Suitable

for prefab buildings and temporary structures.

♦ Cost-Effective

More affordable than stainless steel or aluminum, with a long service life (10–30 years with proper

zinc coating).

♦ Fireproof & Durable

Non-combustible material, compliant with fire safety standards.

Common Thickness

Galvanized corrugated sheets are defined by base steel thickness and zinc coating weight:

Base Steel Thickness:

Standard range: 0.12mm – 1.5mm

Roofing/walls: 0.3mm – 0.6mm (balance of strength & cost)

Heavy-duty use (industrial): 0.8mm+

Zinc Coating Weight:

Standard coating: 40–275 g/m² (both sides)

High-performance: Up to 275 g/m² for extreme corrosion resistance.

Primary Applications

✅Construction: Factory roofs, wall cladding, warehouses, canopies.

✅Transportation: Highway sound barriers, tunnel linings.

✅Agriculture: Greenhouse roofs, livestock shelters.

✅Temporary Structures: Construction site fencing, modular housing.

Does galvanized roofing sheet rust?

The answer is yes, but very slowly. In fact, slow enough that it's usually not a problem. This is

why galvanized steel has been in use for the last 2,000 years, and why it's probably going to

be okay in your application.
