Galvanized steel sheet is coated with zinc, giving better protection against rust and humidity, especially in coastal cities like Jeddah and Dammam. It is preferred for roofs, tanks, and outdoor projects exposed to rain and high heat.
For residential and farm roofs, 0.45 to 0.6 mm galvanized sheet usually provides enough stability. Walls, boxes, and silos may require greater thickness based on load and location. Match the thickness to your project requirements before purchase.
Prices vary by thickness, size, quantity, and delivery location across Saudi Arabia. They may be quoted per sheet, per square meter, or per ton. Request an updated quote from Matkel after confirming the dimensions and quantity you need.
Galvanized steel sheet handles high heat and humidity well when the zinc coating is adequate. However, constant exposure to salt air in coastal areas can accelerate corrosion. Choose an appropriate galvanization thickness and add thermal insulation if needed.
It does not need heavy maintenance if the galvanizing is intact, but periodic inspection is wise for outdoor projects. In Saudi summers, adding thermal insulation can reduce heat transfer and rain noise, especially in suspended roofs.
