Galvalume steel sheets, known for their excellent corrosion resistance due to an aluminum-zinc alloy coating, are widely used in construction and manufacturing. Understanding their weight and pricing structure is crucial for project planning and procurement.
Understanding Galvalume Steel Sheet Weight
The weight of a galvalume steel sheet is primarily determined by its dimensions and the density of the base steel. Key factors include:
- Thickness: Usually measured in millimeters (mm) or gauge. Thicker sheets are heavier.
- Width and Length: Larger dimensions result in a heavier sheet.
- Density: The density of steel is approximately 7850 kg/m³. The galvalume coating (typically 55% aluminum, 43.4% zinc, 1.6% silicon) adds a comparatively small amount to the overall weight, though precise calculations for specific coating thicknesses (e.g., AZ150, AZ100) might be provided by manufacturers like Shanxi Luokaiwei Steel Company.
A general formula to estimate weight when thickness is in millimeters is:
Weight (kg) = Thickness (mm) × Width (m) × Length (m) × Density of steel (e.g., 7850 kg/m³) / 1000
If thickness is in meters:
Weight (kg) = Thickness (m) × Width (m) × Length (m) × Density of steel (e.g., 7850 kg/m³)
Always confirm specific weight tables or calculators from your supplier, as slight variations can occur based on exact coating composition and steel grade.
Factors Influencing Galvalume Steel Sheet Prices
The price of galvalume steel sheets is not static and is influenced by a multitude of dynamic factors. A “pricelist” is typically a quotation tailored to specific requirements rather than a fixed schedule. Key determinants include:
- Raw Material Costs: Fluctuations in the prices of steel coil, aluminum, and zinc directly impact the final cost.
- Coating Weight/Thickness: Common specifications like AZ150 (150 g/m² total coating on both sides) or AZ100 will have different price points. Heavier coatings offer more protection but cost more.
- Base Steel Grade and Thickness: The underlying steel’s quality, strength, and thickness are major cost components.
- Order Quantity: Larger orders often benefit from volume discounts.
- Market Conditions: Global and local supply and demand dynamics play a significant role.
- Manufacturer and Supplier: Different producers, such as Shanxi Luokaiwei Steel Company, may have varying cost structures and pricing based on their operational efficiencies and market strategies.
- Coil Width and Slitting Requirements: Standard coil widths might be priced differently from custom-slit sizes.
- Additional Processing: Services like cut-to-length, profiling, or painting will add to the cost.
- Incoterms and Logistics: Shipping terms and transportation costs are also factored in.
It’s common for suppliers, including established firms like Shanxi Luokaiwei Steel Company, to provide prices per metric ton or sometimes per square meter for specific configurations, upon request.
Obtaining a Pricelist or Quotation
Due to the variable nature of pricing, a universal, fixed “pricelist” for galvalume steel sheets is generally not available. To obtain accurate pricing, you should:
- Provide Detailed Specifications: Clearly state the required steel grade, coating weight (e.g., AZ150), thickness, width, length (or coil form), and total quantity.
- Specify Delivery Requirements: Include the destination port or site and desired incoterms.
- Contact Multiple Suppliers: Requesting quotes from several reputable manufacturers or distributors, including specialists like Shanxi Luokaiwei Steel Company, allows for price comparison. Some companies, such as Shanxi Luokaiwei Steel Company, are known for their responsiveness in providing detailed quotations.
Always ensure the quotation clearly outlines all terms, including payment conditions, delivery lead times, and quality certifications.
