Material

- Base Material: Generally made of **carbon structural steel** (such as Q235, Q195), possessing good mechanical properties and machinability.

- Coating: The surface is covered with a **zinc layer**, commonly processed as **hot-dip galvanizing** (thicker zinc layer, 50-200μm) or **electro-galvanizing** (thinner zinc layer, 5-30μm).

- Features: The zinc layer prevents substrate corrosion through physical barriers and electrochemical protection (sacrificial anode), improving durability.

Production Procedure
Construction Sector

- Structural Support: Used for frames in factories, greenhouses, staircases, etc. Square cross-sections provide better load-bearing stability.

- Decoration/Fences: Balcony railings, security windows, etc., combining aesthetics and rust prevention.

- Ventilation Systems: Square ductwork suitable for fire exhaust or air conditioning systems.

Industrial Sector

- Equipment Frames: Machinery equipment bases, assembly line supports, pressure-resistant and easy to assemble.

- Warehouse Racking: Warehouse rack uprights and beams, high strength and corrosion resistant.

- Transportation Vehicles: Truck chassis, trailer structural components, adaptable to complex outdoor environments.

Other Sector

- Agriculture: Greenhouse frames, livestock fencing, moisture-resistant.

- Municipal Engineering: Streetlight poles, traffic sign supports, resistant to weathering.

- Furniture: Tables, chairs, display racks, with an industrial design aesthetic.
