SGCC GI Steel Features
In addition to the common corrosion resistance and processability of galvanized steel, SGCC galvanized steel offers unique advantages due to its standardized specifications, production processes, and performance details, as follows:
- Strict standardized performance indicators ensure higher quality stability.
- Superior adhesion between the zinc coating and the substrate, minimizing peeling during processing.
- Specialized surface treatment processes to accommodate a wider range of application requirements.
- More stable mechanical properties in low-temperature environments.
- Better compatibility with coatings, resulting in superior performance in secondary processing (pre-painting, coating, composite materials).
Applications of SGCC Galvanized Steel
- Construction industry: Outdoor steel structures (such as supports and guardrails), roof and wall materials, ventilation ducts, etc.
- Automotive industry: Body components (such as chassis parts and door frames), interior support structures.
- Home appliance manufacturing: Refrigerator and washing machine shells and liners, air conditioner outdoor unit components.
- Industrial equipment: distribution box and control cabinet housings, mechanical protective covers, pipes and brackets in humid environments.
- Outdoor facilities: billboard frames, traffic signs, streetlight poles, etc.
FAQ about SGCC
Q1: What is the difference between SGCC and SGCH?
A: SGCC has relatively lower hardness, better formability, and corrosion resistance; SGCH has higher hardness and strength than SGCC, but relatively poorer plasticity and formability.
Q2: Can SGCC replace stainless steel?
A: SGCC galvanized steel can be used in general corrosive environments, but stainless steel is still required in strong acid/alkali environments.
Q3: How is the zinc coating thickness of SGCC tested?
A: Using an X-ray fluorescence analyzer (XRF) or laboratory weighing method (in accordance with ISO 1460 standards).
Q4: Can the bright-finished surface (F) be used outdoors?
A: Yes, but it must be combined with sufficient zinc coating (e.g., Z120+) or a protective coating; otherwise, its weather resistance is inferior to that of the zinc flower surface.
Q5: Do you supply other galvanized steel products besides coils, sheets, and strips?
Yes, we also supply galvanized corrugated steel sheets, galvanized structural steel, galvanized wire, galvanized pipes, etc.
