Product Introduction & System Anatomy

Engineered for Harsh Mining, Industrial Fabrication & Extreme Weather

Champion Frameless Corrugated Steel Arch canopies eliminate all internal purlins, rafters, and lattice trusses. High-strength steel coils are continuously roll-formed and curved on site into rigid arch panels, then locked together with automated 360° mechanical seams. The result is an indestructible self-supporting steel shell anchored continuously to reinforced concrete curb foundations.

⚙️

100% Clear-Span Interior Height

Without truss chord drop, heavy dump trucks, mobile cranes, and front-end loaders utilize 100% of the internal arch clearance.

🌪️

Hurricane & Hail Proof Durability

Heavy 1.0mm–1.5mm corrugation resists severe falling rock impacts, heavy snow loads up to 2.0 kN/m², and 160 km/h hurricane winds.

⏱️

High-Velocity Field Seaming

Continuous roll-forming seamer delivers rapid installation speed: up to 150 m² fully arched and sealed per working day.

Enterprise Value Proposition

Engineered Superiority Over Conventional Construction

Quantifiable lifecycle savings, extreme rapid mobilization, and zero operational downtime for heavy enterprise applications.

⚙️

100% Frameless & Zero Internal Trusses

Continuous roll-formed corrugated steel arch shell requires zero internal support frames, rafters, or purlins, maximizing 100% of usable volume.

🛡️

Galvalume / G90 High-Tensile Steel Coil

Fabricated on-site from 0.8mm–1.5mm Galvalume steel coils with 360° mechanical lock seams for permanent 100% leak-proof durability.

🌪️

Extreme Wind, Hail & Fire Resistance (Class A1)

Engineered arched shell geometry naturally distributes aerodynamic wind pressures up to 160 km/h and resists severe rockfall/hail impact.

Engineering Definition

Pure Self-Supporting Corrugated Steel Arch

This system is a continuous roll-formed metal shell fixed to a reinforced concrete curb. It does not use shipping containers, tubular roof trusses, PVDF roof membranes or ground-mounted corner castings.

  • Continuous AZ150/AZ180 Galvalume corrugated steel shell
  • Mechanical double-lock seams with no roof fastener penetrations
  • Galvanized base channel anchored to a project-specific concrete curb
  • Final geometry, thickness and anchorage calculated from actual site loads
