Heat Resistant Galvanized Corrugated Steel Sheet Gi

Using hot-dip galvanized steel sheet as the base material, a dense zinc layer is formed through continuous hot-dip galvanizing process. Then, it is shaped by corrugated roller pressing to enhance the structural strength. Combined with heat-resistant coating, it strengthens the ability to resist high temperatures and aging. The corrugated structure improves the resistance to bending and drainage performance. The galvanized layer provides long-term anti-corrosion protection, and the heat-resistant coating can reduce heat absorption and delay the aging of the base material. It is suitable for long-term high-temperature sun exposure scenarios, balancing structural safety, service life and overall cost advantages.

Heat Resistant Galvanized Corrugated Steel Sheet Gi integrates anti-corrosion, heat resistance, structural strength and ease of installation, addressing the issues of traditional sheet materials being prone to rust, not being able to withstand high temperatures, and having high maintenance costs. The product can be customized in terms of thickness, zinc coating weight, corrugated shape and size, meeting the needs of ordinary industrial buildings, high-temperature workshops, coastal areas with high salt spray, and high-temperature sun-exposed regions, etc. Once laid, it can be used stably for a long time and reduces the total cycle operation and maintenance costs.

• Long-lasting anti-corrosion performance: The hot-dip galvanized layer forms a physical barrier and cathodic protection, providing superior corrosion resistance in the atmosphere compared to ordinary steel, suitable for humid, coastal, and industrial polluted environments, and extending the service life.
• Stable heat resistance performance: The heat-resistant coating reduces the absorption of sunlight heat, delays coating aging and substrate deformation, and can adapt to long-term high-temperature conditions, maintaining stable appearance and performance.
• Excellent structural strength: The corrugated shape enhances the bending resistance and wind load resistance, with uniform force distribution, suitable for large-span roofs, and able to withstand wind and external force impacts.
• Efficient drainage and waterproofing: The corrugated shape guides rainwater to drain quickly, reducing the risk of water accumulation and leakage, and combined with proper joints, it meets the waterproofing requirements of the roof.
• Lightweight and easy installation: The self-weight is moderate, reducing the roof load, with high transportation and construction efficiency, shortening the construction period, and suitable for new construction and old roof renovation.
• Green and recyclable: The base material is 100% recyclable, in line with RoHS and REACH environmental standards, without heavy metal pollution, and in line with green building requirements.
• Cost controllable: Factory direct supply, with outstanding cost performance, low maintenance frequency in the future, and superior overall usage cost compared to traditional roofing materials.
