Specification: 15-100
Wall thickness: 0.5-3.0mm
Galvanized belt square pipe has the characteristics of strong anti-corrosion and wide range of uses. Below are the detailed features and uses of galvanized strip square pipe:
Characteristics:
Processing: made of hot-rolled or cold-rolled galvanized strip steel or galvanized coil by cold bending forming and then high-frequency welding, or pre-cold-formed square pipe made of hot-dip galvanized treatment.
Anti-corrosion properties: the galvanizing process makes it stronger protection, strong corrosion resistance, zinc layer forms dense quaternary crystals, effectively preventing the penetration of corrosion factors.
Service life: compared with hot-dip galvanized square pipe, the service life may be shorter, especially in harsh environments prone to white spots, peeling, rust and other phenomena.
Usage:
Widely used in curtain wall, construction, machinery manufacturing, steel construction engineering, shipbuilding, solar power generation bracket, steel structure engineering, power engineering and other fields.
Advantages of Pre-Galvanized Pipes
1. Uniform Zinc Coating
Pre-galvanized pipes receive a consistent zinc layer during the steel production process, ensuring even corrosion protection across the entire surface.
2. Cost-Effective for Lightweight Applications
Since the galvanization occurs before fabrication, pre-galvanized pipes are more economical for manufacturers producing standardized pipe sizes in bulk.
3. Smooth Surface Finish
The pre-galvanizing process results in a smoother surface compared to hot-dip galvanized pipes, making them ideal for aesthetic applications like handrails and electrical conduits.
4. Faster Production Time
Since the pipes are pre-coated, manufacturers can skip the post-fabrication galvanizing step, reducing lead times for projects requiring quick delivery.
5. Good Weldability
Pre-galvanized pipes retain better weldability than hot-dip galvanized pipes, as the zinc layer is thinner and less likely to interfere with welding processes.
6. Lightweight Yet Durable
These pipes are often used in applications where heavy-duty corrosion resistance is not the primary concern, such as indoor electrical conduits and HVAC ducting.
7. Environmentally Friendly
The pre-galvanizing process generates fewer emissions and waste compared to traditional hot-dip galvanizing, aligning with sustainable manufacturing practices.
