The difference for G550 full hard galvanized roofing sheet and soft galvanized roofing sheet
| Comparison Dimensions | Full hard Galvanized roofing sheet | Soft Zinc roofing sheet |
| Processing Technology | Direct cold rolling without annealing after galvanizing. | Annealing after galvanizing to soften the material. |
| Hardness and strength | High hardness, high strength | Low hardness, soft and easy to bend |
| Ductility Poor ductility | Poor ductility, difficult to process complex shapes | Good ductility, suitable for deep stamping and complex forming |
| Adhesion of zinc coating | The coating is more tightly bonded to the substrate and has strong corrosion resistance | Annealing may reduce the adhesion of the coating and make it easy to fall off |
| Deformation resistance | Strong, not easily deformed by external forces | Weak, may dent under long-term load |
| Typical uses | Industrial plants, high load environments | Decorative roofs, temporary buildings, special-shaped structures |
G550 Corrugated Galvanized Zinc Roof Sheet
- According to thickness, 0.1-0.6mm is the most produced.
- Type of tile: mainly corrugated tile
- Width: 1000mm before pressing, 900mm after pressing. 900mm before pressing, 800mm after pressing are the two most common tile types, and the most produced. The width can be fine-tuned according to the actual needs of customers, and can also be produced according to the width required by customers.
- Zinc coating: Mostly ordinary zinc layer (30-40g), a high zinc layer can be produced according to customer needs.
- Hardness: divided into soft and hard. Thin tiles (below 0.2mm) are mostly hard (G550), and thick tiles (above 0.2mm) are both hard and soft(G300- 350). The actual hardness still depends on customer needs and is produced on demand.
- Quantity: The minimum order quantity is usually one container (27 tons), but it is usually determined according to the weight of raw material. Please contact us for confirmation of details.
