1. Construction Industry
This is the primary use scenario for galvanized C channels, leveraging their structural stability and corrosion resistance:
Roof and Wall Purlins
They are the most common purlin type for steel structure buildings (workshops, warehouses, stadiums, etc.). Installed horizontally between the main steel beams, they support roof panels (color steel plates, corrugated sheets) and wall cladding, distributing the load evenly to the main structure. Galvanization ensures long service life even in outdoor, humid, or coastal environments.
2. Infrastructure Projects
Highway and Railway FacilitiesUsed in the support frames of highway guardrails, signboards, and lighting poles, adapting to outdoor harsh environments (rain, snow, ultraviolet radiation).
Applied in the construction of railway subgrade supports, tunnel lining auxiliary structures, and contact net brackets, with high strength, meeting the load requirements of transportation infrastructure.
3. Industrial Manufacturing and Equipment
Manufactured into frames for conveyor belts, assembly lines, and mechanical equipment, their customizable length and hole positions meet the precise installation needs of different equipment.
Shelving and Storage Racks
4. Agricultural and Livestock Facilities
As the main structural component of agricultural greenhouses, they support film, solar panels, or shading nets. The zinc coating resists corrosion from soil moisture and fertilizer erosion, extending the greenhouse service life.
Livestock Shed Structures
Used in the frames of chicken coops, pigsties, and cattle sheds, supporting walls, roofs, and feeding equipment, with corrosion resistance adapting to the humid and corrosive environment of livestock houses.
5. Residential and Decoration Fields
Used in suspended ceiling keels, partition wall frameworks, and decorative background wall supports in residential and commercial spaces, featuring lightweight and easy processing characteristics.
Made into small-scale load-bearing structures such as balconies, awnings, and sunshades for residential buildings, with a beautiful appearance and no need for additional painting.

Coating Thickness:
Standard galvanization: 60–80 μm (total for both sides), suitable for indoor or dry outdoor environments, with a service life of 10–15 years. |
|||||
|
Heavy galvanization: 100–120 μm, designed for coastal, humid, or chemical corrosion environments; service life 20–30 years.
Compliance standard: GB/T 13912 (China), ASTM A123 (US), EN ISO 1461 (EU). |
|||||
|
Coating Adhesion:
Passes the bend test (180° bend around a mandrel equal to 2× the channel thickness) without peeling or cracking of the zinc layer. |
|||||
|
Surface Quality:
Uniform zinc coating, no bare spots, blisters, or excessive spangles; minor zinc drips are allowed (≤5 mm in diameter) and can be removed by grinding. |
