Spangle
The "spangle" is a type of surface morphology found on hot-dip galvanized (pure zinc-coated) steel coils. When the steel strip passes through the zinc pot, its surface becomes coated with liquid zinc. As the zinc layer naturally solidifies, zinc grains nucleate and grow, forming what is known as "spangle."
The name "spangle" comes from the fact that the complete zinc crystals display a snowflake-like pattern, which is quite vivid and descriptive.

Applications

Galvanized coil features lightweight, aesthetics, and excellent corrosion resistance. It can be used directly or as the base metal for PPGI steel. Therefore, GI coil has been a new material for many fields, such as construction, shipbuilding, vehicle manufacturing, furniture, home appliances, etc.

1. Construction
They are often used as roofing sheets, interior and exterior wall panels, door panels and frames, the surface sheet of the balcony, ceiling, railings, partition walls, windows, and doors, gutter, sound insulation walls, ventilation ducts, rainwater pipes, rolling shutters, agricultural warehouses, etc.

2. Home Appliances
GI coil is widely applied to home appliances, such as the back panel of air conditioners, and the outer casing of washing machines, water heaters, refrigerators, microwave ovens, switch cabinets, instrument cabinets, etc.


3. Transportation
It is mainly used as decorative panels for cars, corrosion-resistant parts for cars, decks of trains or ships, containers, road signs, isolation fences, ship bulkheads, etc.

4. Light Industry
It is ideal for making chimneys, kitchen utensils, garbage cans, paint buckets, etc. At Wanzhi Steel, we also make some galvanized products, such as chimney pipes, door panels, corrugated roofing sheets, floor decks, stove panels, etc.

5. Furniture, such as wardrobes, lockers, bookcases, lampshades, desks, beds, bookshelves, etc.

6. Other Uses, such as post and telecommunication cable, highway guardrails, billboards, newsstands, etc.
