The zinc coating on galvanized steel acts as a powerful barrier against salt spray and high humidity, making it highly resistant to corrosion in coastal cities like Jeddah and Dammam. Unlike uncoated black steel, which rusts rapidly in these conditions, galvanized sheets maintain structural integrity for years without requiring expensive maintenance.
Look for sheets that comply with Saudi Standards, Metrology and Quality Organization guidelines for hot-dip galvanizing, typically requiring a zinc coating weight of 200 to 400 grams per square meter. Matkel provides certified laboratory test reports for every batch to verify compliance with local engineering standards and extreme climate conditions.
Available thicknesses typically range from 0.5mm to 2.0mm. For roofing and waterproofing applications, 0.6mm or 0.7mm provides optimal flexibility and wind resistance. Heavier load-bearing structures require thicknesses exceeding 1.0mm. Our technical team at Matkel can recommend the precise gauge for your project to maximize durability and minimize material waste.
Welding naturally burns away the zinc coating at joint areas, creating potential rust points. Immediately treat all welds with a cold galvanizing spray or industrial-grade rust inhibitor after installation. Additionally, inspect joints regularly in high-heat regions, and avoid surface scratches during handling to preserve long-term corrosion protection.
Wholesale pricing is calculated based on sheet thickness, zinc coating grade, and total shipment volume across Saudi Arabia. We offer tailored rates for contractors and large-scale developments with flexible payment terms. Our contracts lock pricing upon order confirmation, shielding your project budget from global raw material volatility and local market shifts.
