Galvanized Steel Corrugated Roofing Panels

Galvanized corrugated roofing panels deliver proven durability in harsh weather, combining corrosion-resistant zinc coating with a ribbed design that sheds water efficiently—trusted for decades in agricultural, industrial, and residential projects.

Description

The Roofing Solution That’s Been Weathering Storms Since Day One

We’ve seen countless roofing materials come and go over our 15 years in the steel industry. But galvanized corrugated panels? They remain a staple for good reason. These aren’t your average roofing sheets – they’re engineered to handle everything from monsoon rains to scorching desert heat while staying put for decades.

What makes our panels stand out? Start with the Z275-Z600 zinc coating. In coastal Bangladesh where we’ve installed over 500,000 sqm, these panels still look sharp after 25 years with minimal maintenance. The cold-rolled SGCC/DX51D steel (300-550 MPa tensile) gives you that sweet spot between strength and workability – tough enough for industrial warehouses but light enough (just 4.5-7.5 kg/m²) for residential retrofits.

  • The corrugated profile isn’t just about looks – it increases load capacity to 2.5 kN/m² while creating natural water channels. We’ve tested this in Norway’s snowy regions with excellent results
  • Fire safety matters. Our panels carry A1 non-combustible ratings, a must for chemical plants and data centers
  • The anti-UV coating prevents that chalky degradation we often see in cheaper alternatives. Your roof keeps its integrity and appearance longer

From Farm to Factory – Real Performance Where It Counts

Farmers in Kenya use our 762-600 profile for grain storage – the steep corrugations handle heavy rainfall while resisting rust from grain moisture. Meanwhile, a textile factory in Vietnam chose our 900-225 profile for its wide coverage and 12m custom lengths, cutting installation time by 30%.

Thickness ranges from 0.12mm to 0.8mm, but we typically recommend 0.4mm+ for permanent structures. Surface options include:
– Regular spangle (cost-effective for industrial use)
– Skin-passed (smoother for painted finishes)
– Minimized spangle (when appearance is key)

Why Our Factory Makes the Difference

Being a Chinese manufacturer isn’t just about pricing – it’s about vertical integration. We control everything from coil sourcing to final packaging, which means:
– Consistent Z600 coating (most competitors max out at Z275)
– Precision cutting to ±1mm tolerances
– Custom corrugation patterns within 2 weeks (not the industry-standard 4)

Need special coatings? We’ve formulated Al-Zn alloys for a solar farm in Chile that cut cooling costs by 15%. Or PVDF paint for a luxury resort in the Maldives where salt spray eats ordinary coatings alive.

Talk to us about your project – whether you need 100 or 10,000 panels, we’ll tailor the solution without the sales jargon. Our engineers have handled everything from Antarctic research stations to tropical resorts, so we know how to make steel work for your specific conditions.
