1. Architectural & Landscape Engineering

 
The most common application field, leveraging its natural patina aesthetic and low maintenance:
 

Landscape products: Corten steel flower boxes, garden sculptures, landscape retaining walls, park benches and urban street furniture.

Building facades: Exterior cladding, curtain walls, decorative steel plates for commercial and public buildings (blending with natural and architectural environments).

Small building structures: Canopies, railings, steel frames of outdoor corridors and temporary construction facilities.

2. Civil Engineering & Infrastructure

 
Relying on its good structural strength and atmospheric corrosion resistance, suitable for outdoor load-bearing and semi-load-bearing components:
 

Highway/railway facilities: Guardrails, sound barriers, bridge auxiliary components (abutments, guard plates), railway signal brackets.

Municipal infrastructure: Street lamp poles, billboard steel structures, sewage treatment plant frame components, water conservancy revetment plates.

Port/wharf facilities: Low-salt spray coastal zone auxiliary components (non-load-bearing) such as guard plates and handrails.

3. General Industrial Applications

 
For outdoor industrial equipment and structural parts requiring corrosion resistance and moderate strength:
 

Industrial plant components: Outdoor steel frames of workshops, ventilation duct outer casings, equipment guardrails and support brackets.

Logistics & storage facilities: Outdoor shelf frames, container auxiliary parts, yard fence steel plates.

Agricultural & environmental equipment: Outer casings of agricultural machinery, environmental protection equipment frames (e.g., dust removal equipment) for open-air working conditions.

4. Light Structural Engineering

 
Taking advantage of its good cold formability and weldability for small and medium-sized load-bearing structures:
 

Prefab building parts: Steel plates for prefabricated outdoor houses, temporary construction site offices and warehouse components.

Light steel structures: Steel frames of small outdoor pavilions, scenic spot viewing platforms and bicycle sheds.
